                  CONVERSION TECHNOLOGIES INTERNATIONAL, INC.
                       3,067,000 SHARES OF COMMON STOCK,
3,067,000 REDEEMABLE CLASS A WARRANTS AND 3,067,000 REDEEMABLE CLASS B WARRANTS
    Conversion  Technologies International,  Inc. (the  "Company") hereby offers
3,067,000 shares  (the "Shares")  of Common  Stock, $.00025  par value  ("Common
Stock"),   3,067,000  Redeemable  Class  A   Warrants  (collectively,  "Class  A
Warrants") and 3,067,000  Redeemable Class  B Warrants  (collectively, "Class  B
Warrants").  The Shares, the Class A Warrants  and the Class B Warrants may only
be purchased as a group, consisting of an equal number of each security, but are
transferable separately immediately upon issuance. Each Class A Warrant entitles
the holder to purchase one share of Common  Stock and one Class B Warrant at  an
exercise  price of  $5.85, subject  to adjustment, at  any time  until the fifth
anniversary of the date  of this Prospectus. Each  Class B Warrant entitles  the
holder  to purchase  one share of  Common Stock  at an exercise  price of $7.80,
subject to adjustment, at any  time until the fifth  anniversary of the date  of
this  Prospectus. Commencing one year from the date hereof, the Class A Warrants
and Class B Warrants (collectively, the "Warrants") are subject to redemption by
the Company  at a  redemption price  of $.05  per Warrant  on 30  days'  written
notice,  provided that  the closing  bid price of  the Common  Stock averages in
excess of  $8.20 and  $10.95 per  share, respectively,  for any  30  consecutive
trading days ending within 15 days of the notice of redemption. See "Description
of Securities."
    The  registration statement of  which this Prospectus is  a part also covers
the   offering   for   resale   by   certain   securityholders   (the   "Selling
Securityholders")  of 1,112,500  Class A  Warrants (the  "Selling Securityholder
Warrants"), the  Common  Stock  and  Class B  Warrants  underlying  the  Selling
Securityholder  Warrants, and  the Common Stock  issuable upon  exercise of such
Class B Warrants. See "Concurrent Offering." The Selling Securityholder Warrants
and the securities underlying such Warrants are sometimes collectively  referred
to  as  the  "Selling  Securityholder  Securities."  The  Selling Securityholder
Warrants  are  issuable  on  the  closing   of  the  Offering  to  the   Selling
Securityholders   upon  the  automatic  conversion   of  warrants  (the  "Bridge
Warrants") acquired by them in the Company's private placement in December  1995
(the  "Bridge  Financing"). The  Selling  Securityholders have  agreed  with the
Company not to sell any of the  Selling Securityholder Warrants for at least  90
days  after the closing  of the Offering  and, for the  period expiring 270 days
after such closing, have agreed to certain resale restrictions. See  "Concurrent
Offering."  Sales  of  the  Selling Securityholder  Warrants  or  the underlying
securities, or the potential of  such sales, may have  an adverse effect on  the
market  price of  the securities  offered hereby.  Unless the  context otherwise
requires, all  references  herein to  the  Warrants shall  include  the  Selling
Securityholder Warrants.
    Prior to this offering (the "Offering"), there has been no public market for
the  Common Stock or Warrants, and there can  be no assurance that such a market
will develop. The Common Stock,  the Class A Warrants  and the Class B  Warrants
have  been approved for  listing on the Nasdaq  SmallCap Market ("Nasdaq") under
the symbols CTIX,  CTIXW and  CTIXZ, respectively. The  initial public  offering
price  of the Shares and the Warrants and the exercise prices and other terms of
the Warrants have been determined by  negotiation between the Company and D.  H.
Blair  Investment Banking  Corp. (the  "Underwriter"). See  "Underwriting" for a
discussion of  factors considered  in determining  the initial  public  offering
price.  Pursuant to  Schedule E  of the By-Laws  of the  National Association of
Securities Dealers, Inc.  (the "NASD"), the  Shares and the  Warrants are  being
offered  at a price  no greater than  the maximum recommended  by RAS Securities
Corp., a  qualified  independent  underwriter,  for  the  reason  set  forth  in

THESE  SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE  SECURITIES COMMISSION NOR HAS THE  SECURITIES
 AND  EXCHANGE COMMISSION OR  ANY STATE SECURITIES  COMMISSION PASSED UPON THE
  ACCURACY OR ADEQUACY      OF THIS  PROSPECTUS. ANY  REPRESENTATION TO  THE

                                  THE COMPANY
 
    The Company is an early-stage specialty materials company currently  engaged
in  (i) developing, manufacturing and marketing industrial abrasives produced in
a patented process utilizing industrial  wastes as raw materials, together  with
certain virgin materials, and (ii) recycling cathode ray tube ("CRT") glass used
in  televisions for sale to the original manufacturers of such glass and others.
Substantially all of the Company's revenues  to date have been derived from  its
CRT  glass recycling operations and, although  the Company plans to continue its
CRT  glass  recycling  operations,  the  Company's  primary  focus  is  on   the
development,  manufacture  and  marketing  of its  abrasives.  The  Company also
utilizes its manufacturing equipment to convert  certain types of CRT glass  and
certain other manufacturing by-products and industrial wastes into manufacturing
raw materials for use by the Company in its production of abrasives and for sale
to other manufacturers.
 
    The   Company's  initial  abrasives  product  is  its  ALUMAGLASS  brand  of
manufactured abrasives. ALUMAGLASS can be used as a loose grain abrasive applied
with blasting equipment or as an ingredient in products such as polishing agents
and non-skid flooring.  Blasting of loose  grain abrasives is  used in  numerous
industries  throughout  the  world  for various  cleaning,  stripping  and other
surface treatment or surface preparations applications such as industrial  metal
finishing, coating removal, structural steel and commercial vehicle cleaning and
preparations   of  surface  substrates.  The  Company  believes,  based  on  its
applications testing,  that ALUMAGLASS  may provide  performance advantages  and
cost savings in comparison to competitive products such as aluminum oxide, steel
grit,  glass  beads, plastic  media and  other  abrasives in  many applications.
Potential purchasers  of  ALUMAGLASS  include  military  and  defense  agencies,
entities  engaged in the electronics,  aerospace, automotive, glass products and
construction industries  and  entities  engaged in  surface  finishing,  coating
removal  and maintenance  of manufacturing and  processing equipment, buildings,
highways, bridges  and  commercial  vehicles and  vessels.  ALUMAGLASS  is  also
marketed as an aggregate for direct incorporation into products such as non-skid
flooring  and  as an  additive for  direct incorporation  into products  such as
plasters, tiles and other construction materials.
 
    ALUMAGLASS is manufactured from an alumino-silicate glass which the  Company
produces  in  a  glass melting  furnace  customized for  the  Company's patented
process. The Company's technology enables it to produce such glass utilizing  as
raw  materials primarily waste products from  the aluminum and other industries,
including the  electronics industry  with which  the Company  has established  a
relationship  through its  CRT glass  recycling. In  many cases,  the Company is
either paid to take these waste materials or receives them at little or no cost.
The Company  believes  that  its  ability to  procure  raw  materials  utilizing
recycling and recovery techniques will enable it to offer its products at a cost
savings to comparable products for many applications.
 
    The  Company's strategy is to focus its efforts on the sale and marketing of
its ALUMAGLASS product line and, if warranted by market demand for its abrasives
products, the  Company may  use a  substantial portion  of the  proceeds of  the
Offering  to increase its manufacturing capacity  by building a second melter at
 
                                       3
<PAGE>
its facility  in Dunkirk,  New York.  The Company  may also  seek  opportunities
within  the  United  States  and  abroad  to  construct  and  operate additional
abrasives manufacturing  facilities,  which  may  include  CRT  glass  recycling
operations,   either   independently  or   through   joint  ventures   or  other
collaborative arrangements  with  strategic  partners. At  the  same  time,  the
Company plans to continue its CRT glass recycling business, which it believes is
important  to its strategic positioning as a waste conversion company as well as
its ability to continue to obtain  raw materials for its manufactured  products.
The  Company also intends  to utilize certain of  its manufacturing equipment to
convert manufacturing by-products and other industrial wastes into raw materials
for use by the Company in the production of its abrasives or for sale to others.
The Company also  intends to continue  its research and  development efforts  to
identify  and  test additional  applications  for its  ALUMAGLASS  abrasives, to
pursue the  development of  processes  to manufacture  other products,  such  as
specialty  glass and glass ceramics, utilizing industrial waste as raw materials
and to identify  synergistic products,  services or technologies  that could  be
available  to  the  Company  through  acquisition,  corporate  teaming  or other
opportunities.
 
    The  Company  has  experienced   significant  operating  losses  since   its
inception.  At  March  31,  1996,  the Company  had  an  accumulated  deficit of
approximately  $(15,164,000),  a  working   capital  deficit  of   approximately
$(7,366,000) and a negative net worth of approximately $(4,771,000). The Company
incurred  an operating loss  of approximately $(11,909,000)  for the fiscal year
ended June  30,  1995, and  has  incurred  an operating  loss  of  approximately
$(1,938,000)  for the nine months ended March 31, 1996. The Company expects that
it will continue  to incur  losses until  such time,  if ever,  as revenues  are
sufficient to fund its continuing operations. There can be no assurance that the
Company  will ever  generate sufficient  revenues to  achieve profitability. The
Company has received  a report from  its independent auditors  that includes  an
explanatory  paragraph  indicating that  there is  substantial  doubt as  to the
ability of the Company to continue as a going concern. For a discussion of these
and other risks associated  with an investment in  the Shares and Warrants,  see
"Risk  Factors" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
    The Company's operations are conducted through its wholly-owned  subsidiary,
Dunkirk  International Glass  and Ceramics Corporation  ("Dunkirk"). The Company
acquired Dunkirk in  August 1994 pursuant  to a merger  (the "Merger") in  which
holders  of Dunkirk's common stock received shares of the Company's Common Stock
in exchange for their shares of  Dunkirk common stock. Dunkirk was  incorporated
in  Delaware in July  1990 and was in  the development stage at  the time of the
Merger. The Company was incorporated under the laws of the State of Delaware  in
June  1993  for  the purpose  of  acquiring  Dunkirk and  conducted  no business
activities prior to the Merger. All references to the Company in this Prospectus
include the Company and Dunkirk, unless the context otherwise requires.
 
    The Company owns and operates  a 230,000 square foot manufacturing  facility
in  Dunkirk, New  York. Its  executive offices  are located  at Bethany Crossing
Office Center, 82  Bethany Road,  Hazlet, New  Jersey 07730,  and its  telephone
number is (908) 888-3828.
 
    ALUMAGLASS-TM- is a trademark of the Company.

                                  RISK FACTORS
 
    The securities offered hereby are speculative in nature and an investment in
the  Shares and the Warrants  offered hereby involves a  high degree of risk. In
addition to  the other  information contained  in this  Prospectus,  prospective
investors  should carefully  consider the  following risk  factors in evaluating
whether to purchase the Shares and the Warrants offered hereby.
 
    ACCUMULATED DEFICIT; WORKING CAPITAL DEFICIT; NEGATIVE NET WORTH; HISTORY OF
OPERATING LOSSES; EXPECTATION  OF FUTURE  LOSSES.  The  Company has  experienced
significant operating losses since its inception. At March 31, 1996, the Company
had  an accumulated  deficit of  approximately $(15,164,000),  a working capital
deficit of approximately $(7,366,000) and a negative net worth of  approximately
$(4,771,000).   The  Company   incurred  an  operating   loss  of  approximately
$(11,909,000) for  the fiscal  year ended  June 30,  1995, and  has incurred  an
operating loss of approximately $(1,938,000) for the nine months ended March 31,
1996.   Such  losses  have  resulted  principally  from  limited  revenues  from
operations  and  costs  associated  with   the  development  of  the   Company's
technologies,  general  and  administrative expenses  and  a  one-time, non-cash
charge to  operations  relating  to  the write-off  of  purchased  research  and
development  technologies in  conjunction with the  Merger that  had not reached
technological feasibility and, in the opinion of management, had no  alternative
use.  The  Company has  experienced  decreased revenues  and  incurred increased
losses to date  and expects that  it will  continue to incur  losses until  such
time,  if  ever, as  revenues  from product  sales  are sufficient  to  fund its
continuing operations. The Company's profitability will depend on its ability to
commercialize its abrasives products. There can be no assurance that the Company
will  ever   generate  sufficient   revenues  to   achieve  profitability.   See
"Management's  Discussion and  Analysis of  Financial Conditions  and Results of
Operations."
 
    GOING CONCERN EXPLANATORY  PARAGRAPH IN INDEPENDENT  AUDITORS' REPORT.   The
Company  has received  a report from  its independent auditors  that includes an
explanatory paragraph  indicating that  there  is substantial  doubt as  to  the
ability  of the Company to continue as  a going concern. Among the factors cited
by the auditors  as raising  substantial doubt as  to the  Company's ability  to
continue  as a  going concern  is that  the Company  has generated  only minimal
revenues, has incurred significant losses since inception, has a working capital
and stockholders' deficiency  and is  dependent upon  additional financing.  See
Report of Independent Auditors.
 
    CAPITAL  INTENSIVE BUSINESS; NEED  FOR ADDITIONAL FINANCING.   The Company's
business is capital intensive. The Company  believes that the net proceeds  from
the  Offering, together with  cash generated from operations,  will enable it to
fund its operations for at least 12 months following completion of the Offering.
If the Company is not  profitable prior to such  time, the Company will  require
additional  financing. The Company  has no commitments  for any future financing
and there can be no assurance that the Company will be able to obtain additional
financing in the  future from either  debt or equity  financings, bank loans  or
other sources on acceptable terms or at all. If available, any additional equity
financings may be dilutive to the Company's stockholders and any debt financings
may  contain  restrictive covenants  and  additional debt  service requirements,
which could adversely affect the Company's operating results. If the Company  is
unable  to  obtain necessary  financing, it  will  be required  to significantly
curtail  its  activities  or  cease  operations.  See  "Use  of  Proceeds"   and
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations."
 
    SUBSTANTIAL INDEBTEDNESS; DEBT SERVICE REQUIREMENTS; USE OF PROCEEDS TO  PAY
OUTSTANDING   INDEBTEDNESS  AND  PAST  DUE  ACCOUNTS  PAYABLE;  CONSEQUENCES  OF
DEFAULT.    At  March  31,  1996,  Dunkirk  had  outstanding  an  aggregate   of
approximately $12,300,000 of indebtedness (excluding capital lease obligations),
substantially all of which is secured by the assets of Dunkirk and guaranteed by
the  Company. Accordingly, the Company is subject to all of the risks associated
with substantial indebtedness,  including the  risk that  cash flow  may not  be
sufficient  to make required payments of principal and interest on indebtedness.
The Company  will  require  substantial  cash flow  to  meet  its  debt  service
requirements   relating  to   its  outstanding   indebtedness,  which  aggregate
approximately $1,647,000 (excluding capital  lease obligations and  indebtedness
to  be repaid  from the net  proceeds of  the Offering) for  the 12-month period
following the closing of the Offering. The  Company expects to use a portion  of
the proceeds of the Offering to meet its debt service requirements if funds from
operations are insufficient to do so. To the extent that all of Dunkirk's assets
continue  to be pledged, such assets will  not be available to secure additional
indebtedness, which may adversely affect the
 
                                       7
<PAGE>
Company's ability to borrow in the future. A substantial portion of the proceeds
of the  Offering will  be used  to repay  indebtedness, including  approximately
$2,318,000  of Bridge Notes and $1,348,500 of other indebtedness (which includes
approximately $112,000  of deferred  principal and  interest which  the  Company
intends to pay out of working capital proceeds). Further, at March 31, 1996, the
Company   had  approximately  $2,600,000   of  accounts  payable,  approximately
$1,650,000 of which are more than 30 days  past due and which will be paid  with
the  proceeds of the Offering and the remainder of which are expected to be paid
with funds  from  operations.  However,  in  the  event  that  the  Company  has
insufficient cash to fund its operations and meet its debt service requirements,
the  Company may use  the $2,200,000 of  proceeds allocated to  build its second
melter at the Dunkirk facility for  working capital. In such event, the  Company
may  be required to  obtain additional financing  in order to  build such second
melter. The Company currently has no  commitments or arrangements to obtain  any
such  financing and there can  be no assurance that  the Company can obtain such
financing on  acceptable  terms or  at  all. See  "Management's  Discussion  and
Analysis  of Financial Condition and Results of  Operations" and Note 4 and Note
10 of  Notes  to Consolidated  Financial  Statements  for a  discussion  of  the
payments due under the Company's indebtedness.
 
    In  addition, a portion of the  Company's indebtedness is subject to various
covenants. In the event of a default in payment of outstanding indebtedness,  or
in  the event  of a  default arising out  of a  violation of  any covenants, the
Company and/or Dunkirk may lose all or  a portion of its assets and the  Company
and/or  Dunkirk may  be forced to  materially reduce its  business activities or
cease its  operations.  Certain  of  the  instruments  governing  the  Company's
indebtedness  also  contain default  provisions relating  to insolvency  and the
inability to pay debts as  they become due. Although  the Company may be  deemed
insolvent,  the Company has not received any notice that a creditor has enforced
or intends to enforce any  rights relating to any  possible default or that  any
action will be taken against the Company.
 
    LIMITED OPERATING HISTORY; NEW BUSINESS; LIMITED PRODUCT SALES.  The Company
has  a limited operating history and substantially all of its revenues have been
derived from  recycling  CRT  glass.  The Company  has  only  generated  minimal
revenues  from ALUMAGLASS sales. The construction  of the Company's first melter
to produce its ALUMAGLASS abrasives was completed in February 1995, and  limited
production of its ALUMAGLASS abrasives commenced in the spring of 1995. Although
the  Company  recently  commenced  limited commercial  sales  of  its ALUMAGLASS
abrasives, there  can  be  no  assurance  that  the  Company  will  be  able  to
manufacture  and  market  successfully  its  ALUMAGLASS  abrasives.  The Company
intends to use a substantial portion of  the proceeds of the Offering to  expand
its  abrasives  business. While  attempting to  commercialize its  products, the
Company will be subject to risks inherent in a new business. Such risks  include
unanticipated   problems  relating   to  environmental   regulatory  compliance,
manufacturing, the competitive  environment in  which the  Company operates  and
marketing  problems,  and  additional  costs  and  expenses  may  exceed current
estimates. There  can  be no  assurance  that,  even after  the  expenditure  of
substantial  funds  and efforts,  the Company  will ever  achieve or  maintain a
substantial level  of  sales  of  its  products.  The  failure  to  successfully
manufacture  or market  ALUMAGLASS will  have a  material adverse  effect on the
Company's financial  condition  and results  of  operations. See  "--  Uncertain
Market  Acceptance of Abrasives" and "-- Equipment Failure, Limited Engineering,
Design and Construction Experience; Limited Manufacturing Experience."
 
    UNCERTAIN MARKET ACCEPTANCE OF ABRASIVES.  To date, the Company has had only
minimal sales  of its  ALUMAGLASS  abrasives. There  can  be no  assurance  that
significant  sales will occur or that  the Company's abrasives will obtain broad
market acceptance. The decision by a potential customer to utilize the Company's
abrasives is, among other things, technical in nature, requiring the customer to
make an evaluation as to whether  changes in its capital equipment or  operating
procedures  will be required in order to realize the performance benefits of the
Company's products. See "Business -- Market Overview -- Abrasives." There can be
no assurance that potential customers will  choose to change their equipment  or
established  procedures or be willing to incur  any necessary costs to make such
changes or that the benefits derived from utilizing ALUMAGLASS will outweigh the
costs incurred to make such changes. Further, there can be no assurance that all
customers will experience  the performance and  cost advantages demonstrated  in
the  Company's ALUMAGLASS applications  testing. For example,  ALUMAGLASS may be
too hard for  certain applications,  such as  removal of  coatings from  certain
plastic or vinyl substrates, in relation to plastic
 
                                       8
<PAGE>
abrasives  or  too soft  for other  applications, such  as etching  titanium, in
comparison to  aluminum  oxide.  In  addition, in  order  to  receive  the  full
performance  and cost benefits of ALUMAGLASS, users must use effective abrasives
reclamation systems and appropriate  blasting pressures. If  the Company is  not
successful  in marketing its abrasives, its ability to generate revenues will be
limited to its  CRT glass  recycling operations, waste  conversion services  and
other  future products and services that  may be developed or otherwise obtained
by the  Company.  The  Company believes  that  there  are a  limited  number  of
potential  CRT  glass  recycling  customers and  that  its  CRT  glass recycling
operations have limited growth potential. In addition, there can be no assurance
that the Company's waste  conversion services will  be successfully marketed  or
that future products and services will be developed or obtained. See "-- Limited
Number of CRT Customers" and "Business."
 
    EQUIPMENT  FAILURE; LIMITED ENGINEERING, DESIGN AND CONSTRUCTION EXPERIENCE;
LIMITED MANUFACTURING EXPERIENCE.  The Company has completed construction of and
operated since spring  1995 one 25-ton-per-day  melter. From time  to time,  the
Company  has experienced mechanical or  technical difficulties with such melter,
which has required repairs and  maintenance that have interrupted the  Company's
ability   to  manufacture  its  abrasives.  Any  such  mechanical  or  technical
difficulties with such melter in the  future could result in an interruption  in
the   Company's  ability  to   manufacture  its  abrasives.   See  "Business  --
Manufacturing, Recycling  and  Conversion  Processes --  Melting  Process."  The
failure  of the Company to  effect prompt repairs and  otherwise keep its melter
operating at targeted  capacities could have  a material adverse  effect on  the
business,  financial  condition and  results of  operations  of the  Company. If
warranted by  sufficient  demand  for  its  ALUMAGLASS  abrasives,  the  Company
anticipates  that  it  will  construct  a  second  melter  and  has  allocated a
substantial portion of the proceeds  of the Offering to  do so. The Company  may
experience  problems associated with the engineering, construction, scale-up and
operation  of  such  melter  and  any  additional  melters,  including,  without
limitation, cost overruns, start-up delays and technical or mechanical problems.
To  date, the Company has engaged in only limited manufacturing and there can be
no assurance that the Company's efforts to expand its manufacturing capabilities
will not exceed  estimated costs  or take longer  than expected,  or that  other
unanticipated problems will not arise that would materially adversely affect the
Company's  business and prospects. See  "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business."
 
    LIMITED SALES  AND  MARKETING  EXPERIENCE.   The  Company  has  had  limited
experience  in  selling  and  marketing  its  abrasives  and  its  recycling and
conversion services. Furthermore, the Company  has assembled only a small  sales
and  marketing organization. There can be no  assurance that the Company will be
able to recruit,  train or  retain qualified personnel  to sell  and market  its
products  and services or that it will  develop a successful sales and marketing
strategy. In addition, for  certain applications of  its abrasives, the  Company
will  be dependent on its distributors for primary marketing efforts or may seek
to enter into joint  venture, licensing or  other collaborative arrangements  to
sell  and  market its  products. Such  arrangements  may result  in the  lack of
control by the Company over the sales and marketing of its products or result in
lower revenues to the Company than  if it marketed its products directly.  There
can  be no assurance that any sales and marketing or other efforts undertaken by
the Company  or on  behalf of  the Company  by others  will be  successful.  See
"Business -- Sales and Marketing."
 
    LIMITED  NUMBER  OF  CRT  CUSTOMERS.   To  date,  substantially  all  of the
Company's revenues have  been derived  from recycling  CRT glass  for a  limited
number  of customers. Certain of the  Company's contracts with its CRT customers
contain minimum Company  purchase requirements  and, in  certain cases,  minimum
customer  purchase obligations. For the fiscal year  ended June 30, 1995 and the
nine months ended  March 31, 1996,  three of the  Company's CRT glass  recycling
customers,  Techneglas,  Inc., Thomson  Consumer  Electronics, Inc.  and Toshiba
Display Devices,  Inc.,  each accounted  for  more  than 10%  of  the  Company's
revenues and, in the aggregate, accounted for approximately 90% of the Company's
revenues.  The loss of any one of  these customers could have a material adverse
effect on  the  Company's financial  condition  and results  of  operations.  In
addition,  even  assuming  that  the Company's  existing  customers  continue to
utilize the Company's CRT  glass recycling services,  the Company believes  that
there  are a limited number  of potential customers for  the Company's CRT glass
recycling operations and that  its CRT glass  recycling operations have  limited
growth  potential. The Company currently obtains  only waste CRT glass generated
from manufacturers of televisions located in the United States, and there are  a
limited number of such
 
                                       9
<PAGE>
manufacturers.  In  addition, such  manufacturers typically  seek more  than one
outlet for their CRT glass, in order  to avoid dependence on any one source.  In
some  cases, manufacturers ship their waste  CRT glass to smelters or landfills.
Further, transportation  costs limit  the  sources from  which the  Company  can
obtain  CRT glass on  a cost-effective basis.  Accordingly, the Company believes
that its ability to  generate revenues from CRT  glass recycling is limited  and
that  the Company will  be dependent on revenues  from its ALUMAGLASS abrasives,
waste conversion  services and  other future  products and  services for  future
growth. See "-- Uncertain Market Acceptance of Abrasives."
 
    UNCERTAIN  INDUSTRIAL  WASTE  SUPPLY.   The  Company  utilizes manufacturing
by-products and industrial  wastes as raw  materials for the  production of  its
ALUMAGLASS  abrasives. In addition, the Company will seek to generate revenue in
the future from converting manufacturing by-products and industrial wastes  into
other finished products or into raw materials to be sold to other manufacturers.
However, there can be no assurance that producers of such by-products and wastes
will  view  the  Company's  processes  as  a  commercially  and  environmentally
acceptable means of disposing of such by-products and wastes or will not find  a
less  expensive means of disposing of such  by-products and wastes. As a result,
the Company may be forced to incur higher costs to procure raw materials for its
manufacturing processes and  may experience difficulty  in obtaining wastes  for
its conversion services. See "Business -- Products and Services."
 
    RISKS  INHERENT IN INTERNATIONAL OPERATIONS.   The Company intends to market
its products  and  services  internationally and  plans  to  seek  opportunities
overseas to construct and operate additional abrasives manufacturing facilities,
which  may  include  CRT  glass recycling  operations,  either  independently or
through joint  ventures  or  other  collaborative  arrangements  with  strategic
partners.  To the extent that the  Company operates its business overseas and/or
sells its products in foreign  markets, it will be subject  to all of the  risks
inherent  in international operations and transactions, including the burdens of
complying with  a wide  variety of  foreign laws  and regulations,  exposure  to
fluctuations  in  currency  exchange  rates  and  tariff  regulations, potential
economic instability and export license requirements. In addition, international
environmental regulations and  enforcement of such  regulations vary by  country
and  are subject to changes which may adversely affect the Company's operations.
See "Business."
 
    COMPETITION.  The Company's manufactured abrasives will compete with product
offerings of other companies, principally  aluminum oxide, glass beads,  plastic
abrasives,  garnet and  steel grit  and, with  respect to  certain applications,
sand, slags, crushed glass or water  blasting techniques. Many of the  companies
offering  such  products  are  large  corporations  with  substantially  greater
technical and financial resources  and sales and  marketing experience than  the
Company.  The Company's ability to effectively compete may be adversely affected
by the ability of these competitors to offer their products at lower prices than
the prices of  the Company's  products and to  devote greater  resources to  the
development  and sales and marketing of their products than are available to the
Company. With  respect to  its industrial  CRT glass  recycling operations,  the
Company  competes with  several other companies  who accept waste  CRT glass for
recycling or  other purposes,  each of  which  may deal  with customers  of  the
Company  and satisfy their  recycling, beneficial use or  disposal needs. In the
market for the  conversion of  manufacturing by-products  and industrial  wastes
into  glass  and  ceramic  manufacturing  raw  materials,  the  Company  will be
competing in the  hazardous and non-hazardous  waste and industrial  by-products
treatment  and disposal markets, which are served by several large companies and
numerous small  companies.  Any  of  such competitors  or  any  other  potential
competitor  may develop technologies superior to those of the Company. There are
several established corporations which offer proprietary high temperature  waste
vitrification  services which may compete with the services and products offered
or proposed to be  offered by the  Company. No assurance can  be given that  the
Company will be able to compete effectively. See "Business -- Competition."
 
    CHARGES  ARISING FROM DEBT ISSUANCE COSTS.   Upon completion of the Offering
and repayment  of the  Bridge  Notes, a  non-recurring charge  representing  the
unamortized  debt discount and  debt issuance costs  incurred in connection with
the Bridge Financing will be recorded as an extraordinary loss in the quarter in
which the  Offering is  completed. The  aggregate debt  discount, debt  issuance
costs  and interest associated with the  Bridge Notes are approximately $535,000
(an aggregate of approximately  $69,000 of interest was  recorded in the  fiscal
quarters  ended  December  31,  1995  and  March  31,  1996).  See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
                                       10
<PAGE>
    DEPENDENCE ON PATENTS  AND PROPRIETARY  TECHNOLOGY.   The Company's  success
will depend, in part, on its ability to maintain protection for its products and
manufacturing processes under United States and foreign patent laws, to preserve
its  trade secrets and  to operate without infringing  the proprietary rights of
third parties. The Company has two patents and two patent applications  pending.
There  can be no  assurance that any  patent applications will  result in issued
patents, that any issued patents will afford adequate protection to the  Company
or  not be challenged, invalidated, infringed or circumvented or that any rights
thereunder will afford competitive advantages to the Company. Furthermore, there
can be no assurance  that others have not  independently developed, or will  not
independently  develop, similar products and technologies or otherwise duplicate
any of the Company's products and technologies.
 
    There can be  no assurance that  the validity  of any patent  issued to  the
Company  would  be upheld  if challenged  by  others in  litigation or  that the
Company's activities would  not infringe  patents owned by  others. The  Company
could  incur substantial costs in defending  itself in suits brought against it,
or in suits  in which the  Company seeks  to enforce its  patent rights  against
others.  Should  the Company's  products or  technologies  be found  to infringe
patents issued to  third parties,  the Company would  be required  to cease  the
manufacture,  use and sale  of the Company's  products and the  Company could be
required to pay substantial damages. In addition, the Company may be required to
obtain licenses  to patents  or other  proprietary rights  of third  parties  in
connection  with the  development and use  of its products  and technologies. No
assurance can be given that any  such licenses required would be made  available
on terms acceptable to the Company, or at all.
 
    The  Company also relies on trade secrets and proprietary know-how, which it
seeks to protect,  in part,  by confidentiality agreements  with its  university
research  partners, employees, consultants, advisors and others. There can be no
assurance that  such parties  will maintain  the confidentiality  of such  trade
secrets  or proprietary  information, or  that the  trade secret  or proprietary
information of the Company will not  otherwise become known or be  independently
developed  by competitors in a manner that  would have a material adverse effect
on the Company's business,  financial condition and  results of operations.  See
"Business -- Intellectual Property."
 
    DEPENDENCE   ON  ENVIRONMENTAL   REGULATION.    Federal,   state  and  local
environmental legislation and regulations mandate stringent waste management and
operations practices, which require  substantial capital expenditures and  often
impose strict liabilities for non-compliance. Environmental laws and regulations
are,  and  will continue  to be,  a  principal factor  affecting demand  for the
technology and services being developed or offered by the Company. The level  of
enforcement  activities by federal, state and local environmental protection and
related agencies,  and changes  in regulations  and waste  generator  compliance
activities, will also affect demand. To the extent that the burdens of complying
with  such laws and regulations may be eased as a result of, among other things,
political factors,  or that  suppliers of  manufacturing by-products  and  other
industrial  wastes find alternative  means to comply  with applicable regulatory
requirements, the Company's ability to  procure such by-products and wastes  and
the  demand for the Company's services  could be adversely affected, which could
have a material adverse  effect on the  Company's business, financial  condition
and  results  of operations.  Any changes  in  these regulations  which increase
compliance  standards  may  require  the  Company  to  change  or  improve   its
manufacturing process. To the extent the Company conducts its business overseas,
international  environmental  regulations will  be applicable.  Such regulations
vary by  country and  are subject  to  changes which  may adversely  affect  the
Company's operations. See "Business -- Environmental Matters."
 
    REGULATORY STATUS OF OPERATIONS.  The Company and its customers operate in a
highly  regulated  environment,  and  the Dunkirk  facility  is  and  any future
facilities may  be  required  to  have various  federal,  state  and/  or  local
government  permits and authorizations, registrations  and/or exemptions. Any of
these permits or approvals may be subject to denial, revocation or  modification
under  various  circumstances. Failure  to comply  with  the conditions  of such
permits, approvals, registrations,  authorizations or  exemptions may  adversely
affect  the installation or operation  of the Company's manufacturing facilities
and may subject the Company to federal, state or locally-imposed penalties.  The
Company's  ability  to  satisfy  the permitting  requirements  for  a particular
facility does not assure that permitting requirements for other facilities  will
be  satisfied.  In  addition, if  new  environmental legislation  is  enacted or
current regulations are amended or are
 
                                       11
<PAGE>
interpreted or  enforced  differently,  the  Company or  its  customers  may  be
required  to obtain additional operating permits, registrations, certifications,
exemptions or  approvals. There  can be  no assurance  that the  Company or  its
customers will meet all of the applicable regulatory requirements.
 
    POTENTIAL ENVIRONMENTAL LIABILITY.  The Company's business exposes it to the
risk that harmful substances may be released or escape into the environment from
its facilities, processes or equipment, resulting in potential liability for the
clean-up  or  remediation  of  the  release  and/or  potential  personal  injury
associated with the  release. Liability  for investigation  and/or clean-up  and
corrective  action costs exists under  the Comprehensive Environmental Response,
Compensation and  Liability Act  of 1980,  as amended  ("CERCLA"), the  Resource
Conservation  and Recovery Act  of 1976, as  amended ("RCRA"), and  the New York
State Environmental Conservation Law.  Additionally, the Company is  potentially
subject  to regulatory liability for  the generation, transportation, treatment,
storage or disposal of hazardous waste if it does not act in accordance with the
requirements of  federal  or  state  hazardous  waste  regulations  or  facility
specific regulatory determinations, authorizations or exemptions. The Company is
also  potentially subject to  regulatory liability for releases  into the air or
water under  the Clean  Air  Act of  1970, as  amended,  and the  Federal  Water
Pollution  Control Act of 1972, as  amended (hereinafter the "Clean Water Act"),
and analogous state laws and regulations and various other applicable federal or
state laws and regulations if it does not comply with those requirements.
 
    The Company may  also be  exposed to certain  environmental risks  resulting
from  the actions of its  CRT glass suppliers and  other suppliers of industrial
wastes.  Although  the  Company  maintains  general  liability  insurance,  this
insurance  is subject  to coverage  limits and  generally excludes  coverage for
losses or liabilities related to environmental damage or pollution. Although the
Company conducts and plans to conduct  its operations prudently with respect  to
environmental   regulations  and  plans  to  structure  its  relationships  with
customers and  contractors  in  a manner  so  as  to minimize  its  exposure  to
environmental  liabilities,  the  Company's  business,  financial  condition and
results of operations could be materially adversely affected by an environmental
claim that  is not  covered or  only  partially covered  by insurance  or  other
available remedy.
 
    In  addition, although the Company does  not utilize any underground storage
tanks, there are several empty tanks at  the Dunkirk facility that were used  by
the former owner of the property to store various materials. An investigation by
an  environmental  engineering  firm  has  disclosed  modest  soil contamination
confined to the immediate vicinity of two tank locations and remediation may  be
required.   Based  on  estimates  from   qualified  environmental  services  and
engineering firms,  total remediation  and tank  closure costs  are expected  to
range   from  approximately   $28,000,  if   no  remediation   is  required,  to
approximately $64,000  if  soil and  groundwater  remediation is  required.  See
"Business -- Environmental Matters."
 
    DEPENDENCE ON KEY MANAGEMENT AND PERSONNEL.  The Company is highly dependent
upon  the efforts of its senior management  and scientific staff. The Company is
also  dependent  upon  its  other  management  personnel,  as  well  as  certain
scientific  advisors and consultants  from Alfred University  and other academic
institutions and organizations. The loss of the services of one or more of these
individuals could have a material adverse effect upon the Company. The Company's
future success will depend in large part upon its ability to attract and  retain
additional  highly skilled  scientific, managerial,  manufacturing and marketing
personnel. The Company faces  competition for hiring  such personnel from  other
companies,  research and  academic institutions,  government agencies  and other
organizations. There can be  no assurance that the  Company will continue to  be
successful in attracting and retaining such personnel. See "Management."
 
    POSSIBLE ADVERSE EFFECTS OF ELECTION OF UNION.  In February 1996, a majority
of  the employees  of Dunkirk  elected the  United Steelworkers  of America (the
"Union") to  act as  their bargaining  representative pursuant  to the  National
Labor Relations Act (the "NLRA"). Dunkirk is obligated under the NLRA to bargain
with  the  Union  in  good  faith. The  outcome  of  such  bargaining  cannot be
determined. There can  be no assurance  that the  election of the  Union or  the
outcome  of the bargaining process  will not result in  higher labor costs, work
stoppages or  strikes  or  otherwise  have a  material  adverse  effect  on  the
Company's   business,  financial   condition  or  results   of  operations.  See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations -- Overview."
 
    POTENTIAL   CONFLICTS  OF   INTEREST  ARISING   FROM  CERTAIN  RELATED-PARTY
TRANSACTIONS.  The Company has  entered into consulting agreements with  certain
directors, principal stockholders and affiliates of certain
 
                                       12
<PAGE>
directors  and principal stockholders  of the Company,  pursuant to which, among
other things, certain of  such persons received warrants  and pursuant to  which
certain  of  such persons  will be  entitled  to receive  success fees  upon the
completion of certain project development activities. Such agreements may result
in conflicts of interest for the  directors and principal stockholders who  are,
or  whose affiliates  are, parties to  such consulting  agreements. The Company,
however, does not believe that the  existence of such agreements will  interfere
with  the ability of the Company's directors to discharge their fiduciary duties
to  the  Company's  stockholders.   See  "Certain  Transactions  --   Consulting
Agreements."
 
    IMMEDIATE  DILUTION.  The purchasers of  Shares and Warrants in the Offering
will experience immediate dilution  of approximately $3.29 or  73.1% in the  per
share  net tangible  book value  of their  Common Stock  ($3.05 or  67.8% if the
Underwriter's over-allotment option is  exercised in full). Additional  dilution
to  public investors, if  any, may result  to the extent  that the Warrants, the
Underwriter's Option and/or outstanding options and warrants are exercised at  a
time  when the  net tangible book  value per  share of Common  Stock exceeds the
exercise price of any such securities. See "Dilution."
 
    CHARGE TO EARNINGS IN THE EVENT OF RELEASE OF ESCROW SECURITIES.  The Escrow
Securities will be released from escrow if the Company attains certain  earnings
levels  over the next two to four years or if the Common Stock trades at certain
levels over the next  three years. The position  of the Securities and  Exchange
Commission  (the "Commission") with respect to such escrow arrangements provides
that in  the  event any  shares  or options  are  released from  escrow  to  the
stockholders   of  the  Company  who   are  officers,  directors,  employees  or
consultants of  the  Company,  a  compensation  expense  will  be  recorded  for
financial reporting purposes. Accordingly, the Company will, in the event of the
release of any Escrow Securities to the Company's officers, directors, employees
or consultants, recognize during the period in which the earnings thresholds are
met  or such stock  levels achieved, a  noncash charge to  earnings equal to the
fair value of such  shares on the  date of their release,  which would have  the
effect  of increasing the Company's loss or reducing or eliminating earnings, if
any, at  such time.  The recognition  of such  compensation expense  may have  a
depressive  effect  on  the  market  price  of  the  Company's  securities.  See
"Principal Stockholders  -- Escrow  Securities." Notwithstanding  the  foregoing
discussion,  there  can  be no  assurance  that  the Escrow  Securities  will be
released from escrow.
 
    POTENTIAL ADVERSE  EFFECTS  OF  PREFERRED STOCK.    The  Company's  Restated
Certificate  of Incorporation authorizes the issuance of shares of "blank check"
preferred stock, which will  have such designations,  rights and preferences  as
may  be determined from time to time by the Board of Directors. Accordingly, the
Board  of  Directors  is  empowered,  without  stockholder  approval,  to  issue
preferred  stock with dividend, liquidation,  conversion, voting or other rights
which could adversely affect the voting power or other rights of the holders  of
the  Common Stock. The preferred stock could be utilized to discourage, delay or
prevent a change in control of the Company. Although the Company has no  present
intention to issue any shares of preferred stock, there can be no assurance that
the  Company will  not do so  in the  future. See "Description  of Securities --
Preferred Stock."
 
    NO DIVIDENDS.  The  Company has not  paid any cash  dividends on its  Common
Stock  and does not expect to declare or  pay any cash or other dividends in the
foreseeable future.  As a  holding  company, the  Company holds  no  significant
tangible assets other than its investments in and advances and loans to Dunkirk.
The  Company's ability to make  cash dividend payments to  holders of the Common
Stock is  dependent  upon the  receipt  of  sufficient funds  from  Dunkirk.  In
addition,  the terms of Dunkirk's $8 million Solid Waste Disposal Facility Bonds
("IDA Bonds") issued through the Chautauqua County Industrial Development Agency
prohibit  Dunkirk  from   paying  dividends   to  the   Company  under   certain
circumstances  during any fiscal year  in excess of 50%  of Dunkirk's net income
for such fiscal  year. See  "Dividend Policy" and  "Management's Discussion  and
Analysis  of  Financial Condition  and Results  of  Operations --  Liquidity and
Capital Resources."
 
    NO PUBLIC  MARKET  FOR  SECURITIES; POSSIBLE  VOLATILITY  OF  MARKET  PRICE;
ARBITRARY DETERMINATION OF OFFERING PRICE.  Prior to the Offering, there has not
been  any  market for  any  of the  Company's securities,  and  there can  be no
assurance that an active trading market  will develop or be sustained after  the
Offering.  The initial public offering price of  the Shares and the Warrants and
the exercise prices  and other  terms of the  Warrants have  been determined  by
negotiation  between the Company  and the Underwriter pursuant  to Schedule E of
the By-laws of the NASD and are  not necessarily related to the Company's  asset
value,  net worth, results of operations or  any other criteria of value and may
not  be   indicative  of   the   prices  that   may   prevail  in   the   public
 
                                       13
<PAGE>
market.  The market prices  of the Common  Stock and the  Warrants could also be
subject to  significant fluctuations  in response  to variations  in  government
regulations relating to the Company's operations, general trends in the industry
and  other factors, including  extreme price and  volume fluctuations which have
been  experienced   by  the   securities  markets   from  time   to  time.   See
"Underwriting."
 
    OUTSTANDING  WARRANTS AND  OPTIONS; EXERCISE  OF REGISTRATION  RIGHTS.  Upon
completion of  the Offering,  the Company  will have  outstanding (i)  3,067,000
Class  A Warrants to purchase  an aggregate of 3,067,000  shares of Common Stock
and 3,067,000 Class  B Warrants;  (ii) 3,067,000  Class B  Warrants to  purchase
3,067,000  shares of Common Stock; (iii)  the Selling Securityholder Warrants to
purchase 1,112,500 shares of Common Stock  and 1,112,500 Class B Warrants;  (iv)
the  Underwriter's Option to purchase an aggregate of 1,226,800 shares of Common
Stock, assuming exercise of the underlying Warrants; (v) options to purchase  an
aggregate  of  80,493  shares  of  Common  Stock  granted  under  the Conversion
Technologies International,  Inc.  1994  Employee  Stock  Option  Plan  and  the
Conversion   Technologies  International,  Inc.  1994   Stock  Option  Plan  for
Non-Employee Directors; (vi) non-qualified options to purchase 50,000 shares  of
Common Stock issued to the President and Chief Executive Officer of the Company;
and  (vii) warrants to purchase  an aggregate of 319,204  shares of Common Stock
issued prior to the Offering. Holders of outstanding options to purchase  71,923
shares  of Common  Stock have  placed such  options into  escrow. See "Principal
Stockholders -- Escrow  Securities." The  Company has reserved  an aggregate  of
510,400  shares of Common Stock for issuance  under its stock option plans as of
the date of this Prospectus. Holders of such warrants and options are likely  to
exercise  them  when, in  all likelihood,  the  Company could  obtain additional
capital on  terms  more favorable  than  those  provided by  such  warrants  and
options.  Further,  while  these  warrants  and  options  are  outstanding,  the
Company's ability  to obtain  additional  financing on  favorable terms  may  be
adversely  affected. The  holders of  the Underwriter's  Option, the  holders of
1,326,166 shares of Common Stock  outstanding upon consummation of the  Offering
and  the holders  of warrants  to purchase 293,365  shares of  Common Stock have
certain demand  and  "piggy-back"  registration rights  with  respect  to  their
securities. The exercise of such rights could involve substantial expense to the
Company.  See  "Management  -- Stock  Option  Plans,"  "Principal Stockholders,"
"Description of Securities" and "Underwriting."
 
    POTENTIAL ADVERSE EFFECT  OF REDEMPTION  OF WARRANTS.   Commencing one  year
from the date of this Prospectus, the Warrants may be redeemed by the Company at
a redemption price of $.05 per Warrant upon not less than 30 days' prior written
notice  if, with respect to  the Class A Warrants, the  closing bid price of the
Common Stock shall have averaged in excess of $8.20 per share and, with  respect
to  the Class B Warrants, $10.95 per  share, in each instance for 30 consecutive
trading days ending  within 15 days  of the notice.  Redemption of the  Warrants
could  force the holders (i) to exercise the Warrants and pay the exercise price
therefor at a time when it may be disadvantageous for the holders to do so, (ii)
to sell the Warrants at the then current market price when they might  otherwise
wish to hold the Warrants or (iii) to accept the nominal redemption price which,
at   the  time  the  Warrants  are  called  for  redemption,  is  likely  to  be
substantially less than the  market value of the  Warrants. See "Description  of
Securities -- Redeemable Warrants."
 
    CURRENT  PROSPECTUS REQUIRED TO EXERCISE WARRANTS.  Holders of Warrants will
be able to  exercise the Warrants  only if  (i) a current  prospectus under  the
Securities  Act relating  to the securities  underlying the Warrants  is then in
effect  and  (ii)  such  securities  are  qualified  for  sale  or  exempt  from
qualification  under the applicable  securities laws of the  states in which the
various holders  of Warrants  reside. Although  the Company  has undertaken  and
intends  to use its best  efforts to maintain a  current prospectus covering the
securities underlying the Warrants following  completion of the Offering to  the
extent  required by federal securities laws, there  can be no assurance that the
Company will be able to do so. The value of the Warrants may be greatly  reduced
if  a  prospectus covering  the  securities issuable  upon  the exercise  of the
Warrants is not kept current or if  the securities are not qualified, or  exempt
from  qualification,  in the  state  in which  the  holders of  Warrants reside.
Persons holding Warrants who  reside in jurisdictions  in which such  securities
are  not qualified and in which there is no exemption will be unable to exercise
their Warrants and would either have to  sell their Warrants in the open  market
or  allow them to expire unexercised. If and when the Warrants become redeemable
by the terms thereof, the Company may  exercise its redemption right even if  it
is  unable to  qualify the underlying  securities for sale  under all applicable
state securities laws. See "Description of Securities -- Redeemable Warrants."
 
    POSSIBLE ADVERSE EFFECT ON LIQUIDITY OF THE COMPANY'S SECURITIES DUE TO  THE
INVESTIGATION  OF D.H. BLAIR INVESTMENT BANKING CORP. AND D.H. BLAIR & CO., INC.
BY THE SECURITIES  AND EXCHANGE  COMMISSION.   The Commission  is conducting  an
investigation concerning various business activities of the Underwriter and D.H.
Blair  & Co., Inc. ("Blair & Co."), a selling group member which will distribute
substantially all of the
 
                                       14
<PAGE>
securities offered  hereby. The  investigation  appears to  be broad  in  scope,
involving  numerous aspects  of the Underwriter's  and Blair  & Co.'s compliance
with the federal securities laws and compliance with the federal securities laws
by issuers whose securities were underwritten by the Underwriter or Blair & Co.,
or in  which the  Underwriter  or Blair  &  Co. made  over-the-counter  markets,
persons  associated with the Underwriter or Blair  & Co., such issuers and other
persons. The Company has been advised by the Underwriter that the  investigation
has  been  ongoing since  at  least 1989  and that  it  is cooperating  with the
investigation. The Underwriter  cannot predict whether  this investigation  will
ever  result in any type of formal enforcement action against the Underwriter or
Blair & Co., or, if so, whether any such action might have an adverse effect  on
the  Underwriter or the securities offered  hereby. The Company has been advised
that Blair  & Co.  intends to  make a  market in  the securities  following  the
Offering. An unfavorable resolution of the Commission's investigation could have
the  effect of limiting  such firm's ability  to make a  market in the Company's
securities, which  could  adversely  affect  the  liquidity  or  price  of  such
securities. See "Underwriting."
 
    POSSIBLE   RESTRICTIONS  ON   MARKET-MAKING  ACTIVITIES   IN  THE  COMPANY'S
SECURITIES.  The Underwriter has advised the Company that Blair & Co. intends to
make a market in the Company's  securities. Rule 10b-6 under the Securities  Act
of 1934, as amended (the "Exchange Act"), may prohibit Blair & Co. from engaging
in  any market-making activities with regard to the Company's securities for the
period from nine business  days (or such other  applicable period as Rule  10b-6
may  provide) prior to  any solicitation by  the Underwriter of  the exercise of
Warrants until the later of the termination of such solicitation activity or the
termination (by waiver or otherwise) of any right that the Underwriter may  have
to  receive a fee for the exercise of Warrants following such solicitation. As a
result, Blair  &  Co. may  be  unable to  provide  a market  for  the  Company's
securities  during  certain  periods  while  the  Warrants  are  exercisable. In
addition, under applicable  rules and  regulations under the  Exchange Act,  any
person  engaged in the  distribution of the  Selling Securityholder Warrants may
not simultaneously  engage  in  market-making activities  with  respect  to  any
securities  of the Company for the applicable "cooling off" period (at least two
and possibly nine business days) prior to the commencement of such distribution.
Accordingly, in  the event  the  Underwriter or  Blair &  Co.  is engaged  in  a
distribution  of the Selling Securityholder Warrants, neither of such firms will
be able  to make  a market  in the  Company's securities  during the  applicable
restrictive  period. Any  temporary cessation  of such  market-making activities
could have an adverse  effect on the market  price of the Company's  securities.
See "Underwriting."
 
    POSSIBLE  DELISTING OF SECURITIES  FROM NASDAQ.   While the Company's Common
Stock, Class A  Warrants and Class  B Warrants meet  the current Nasdaq  listing
requirements and will be initially included on Nasdaq, there can be no assurance
that  the  Company  will  meet the  criteria  for  continued  listing. Continued
inclusion on Nasdaq generally  requires that (i) the  Company maintain at  least
$2,000,000  in  total assets  and $1,000,000  in capital  and surplus,  (ii) the
minimum bid price  of the Common  Stock be $1.00  per share, (iii)  there be  at
least  100,000 shares in the  public float valued at  $200,000 or more, (iv) the
Common Stock have at least two active market makers and (v) the Common Stock  be
held  by at  least 300  holders. If  the Company  is unable  to satisfy Nasdaq's
maintenance requirements, its securities  may be delisted  from Nasdaq. In  such
event,  trading, if any,  in the Common  Stock and Warrants  would thereafter be
conducted in the over-the-counter market in  the so-called "pink sheets" or  the
NASD's  "Electronic Bulletin  Board" and  it could  be more  difficult to obtain
quotations of the market  price of the  Company's securities. Consequently,  the
liquidity  of the Company's securities could be impaired, not only in the number
of securities which could  be bought and  sold, but also  through delays in  the
timing  of transactions,  reduction in security  analysts' and  the news media's
coverage of the Company and lower prices for the Company's securities than might
otherwise be attained.
 
    RISKS OF PENNY STOCK.  If the Company's securities were deleted from  Nasdaq
(see "Risk Factors -- Possible Delisting of Securities from Nasdaq"), they could
become  subject to Rule  15g-9 under the Exchange  Act, which imposes additional
sales practice  requirements  on broker-dealers  that  sell such  securities  to
persons  other than established customers and "accredited investors" (generally,
individuals with net worths in excess of $1,000,000 or annual incomes  exceeding
$200,000  or $300,000 together with their  spouses). For transactions covered by
such rule, a broker-dealer must make a special suitability determination for the
purchaser and have received the  purchaser's written consent to the  transaction
prior  to  sale. Consequently,  such rule  may adversely  affect the  ability of
broker-dealers to sell  the Company's  securities and may  adversely affect  the
ability of purchasers in the Offering to sell in the secondary market any of the
securities acquired.
 
    Commission  regulations define a  "penny stock" to  be any non-Nasdaq equity
security that has a  market price (as  therein defined) of  less than $5.00  per
share   or   with   an  exercise   price   of   less  than   $5.00   per  share,
 
                                       15
<PAGE>
subject to  certain exceptions.  For any  transaction involving  a penny  stock,
unless  exempt, the rules require delivery, prior  to any transaction in a penny
stock, of a disclosure schedule prepared by the Commission relating to the penny
stock market. Disclosure is also required  to be made about commissions  payable
to  both  the  broker-dealer  and  the  registered  representative  and  current
quotations for the securities.  Finally, monthly statements  are required to  be
sent disclosing recent price information for the penny stock held in the account
and information on the limited market in penny stocks.
 
    The  foregoing  required  penny stock  restrictions  will not  apply  to the
Company's securities if such  securities are listed on  Nasdaq and have  certain
price  and volume information provided on a current and continuing basis or meet
certain minimum net tangible assets or average revenue criteria. There can be no
assurance that the Company's  securities will qualify  for exemption from  these
restrictions.  In any event,  even if the Company's  securities were exempt from
such restrictions, it would remain subject  to Section 15(b)(6) of the  Exchange
Act,  which gives the  Commission the authority  to prohibit any  person that is
engaged in unlawful  conduct while participating  in a distribution  of a  penny
stock  from associating with a broker-dealer  or participating in a distribution
of a penny stock, if  the Commission finds that such  a restriction would be  in
the  public interest. If the  Company's securities were subject  to the rules on
penny stocks,  the  market  liquidity  for the  Company's  securities  could  be
severely adversely affected.
 
    SHARES  ELIGIBLE FOR FUTURE SALE.  Future  sales of Common Stock by existing
stockholders pursuant to  Rule 144  under the  Securities Act,  pursuant to  the
Concurrent  Offering or otherwise, could have an  adverse effect on the price of
the Company's securities. Pursuant to the Concurrent Offering, 1,112,500 Selling
Securityholder Warrants and the underlying  securities have been registered  for
resale concurrently with the Offering, subject to a contractual restriction that
the  Selling Securityholders not sell any of the Selling Securityholder Warrants
for at least 90  days from the  closing of the Offering  and, during the  period
from  91 to  270 days  after the  closing of  the Offering,  only sell specified
percentages of such Selling Securityholder Warrants. Upon the sale of the Shares
and the Warrants  offered hereby,  the Company will  have outstanding  4,992,150
shares  of  Common  Stock, 3,067,000  Class  A  Warrants and  3,067,000  Class B
Warrants (5,452,200  shares of  Common  Stock, 3,527,050  Class A  Warrants  and
3,527,050  Class  B  Warrants  if  the  Underwriter's  over-allotment  option is
exercised in full). The  shares of Common  Stock, the Class  A Warrants and  the
Class  B  Warrants  sold  in  the  Offering  will  be  freely  tradeable without
restriction under the  Securities Act,  unless acquired by  "affiliates" of  the
Company  as that term is defined in  the Securities Act. The remaining 1,925,150
outstanding shares  of  Common  Stock are  "restricted  securities"  within  the
meaning  of Rule 144 under the Securities  Act and will become eligible for sale
under Rule 144 commencing in August 1996. The holders of approximately 1,891,440
shares (or approximately 98% of the shares of Common Stock outstanding prior  to
the  Offering (after giving effect  to the conversion of  the Series A Preferred
Stock into  Common Stock)),  and the  holders  of all  options and  warrants  to
purchase  shares of Common Stock have agreed not to sell or otherwise dispose of
any securities of the Company  for a period of 13  months from the date of  this
Prospectus without the prior written consent of the Underwriter. The Underwriter
and   the  holders  of  1,326,166  shares   of  Common  Stock  outstanding  upon
consummation of the Offering have registration rights covering their securities.
Sales of Common Stock, or  the possibility of such  sales, in the public  market
may  adversely affect  the market  price of  the securities  offered hereby. See
"Concurrent Offering,"  "Description of  Securities"  and "Shares  Eligible  for
Future Sale."
 
    BROAD  DISCRETION  AS  TO USE  OF  PROCEEDS.   Of  the net  proceeds  of the
Offering, approximately $3,498,500  or approximately 30%  has been allocated  to
working  capital  and  other  general  corporate  purposes  (and  not  otherwise
allocated for  a  specific  purpose) and  will  be  used for  such  purposes  as
management may determine in its sole discretion without the need for stockholder
approval  with respect to any such allocation.  In addition, if the Company does
not build a second melter for the production of ALUMAGLASS, an additional amount
of approximately $2,200,000 currently allocated to capital expenditures for such
melter would become available  for working capital  and other general  corporate
purposes. See "Use of Proceeds."

                                DIVIDEND POLICY
 
    The Company has not paid any cash dividends on its Common Stock and does not
expect  to declare or pay any cash or other dividends in the foreseeable future.
As a holding  company, the Company  holds no significant  tangible assets  other
than its investments in and advances and loans to Dunkirk. The Company's ability
to  make cash dividend payments to holders of the Common Stock is dependent upon
the receipt of sufficient funds from Dunkirk. In addition, the terms of the  IDA
Bonds  prohibit  Dunkirk  from paying  dividends  to the  Company  under certain
circumstances during any fiscal  year in excess of  50% of Dunkirk's net  income
for  such fiscal  year. See "Management's  Discussion and  Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the Shares and the Warrants
offered hereby, after deducting underwriting discounts and commissions and other
estimated  expenses  of  the  Offering,   are  estimated  to  be   approximately
$11,803,000  (approximately  $13,672,000  if  the  Underwriter's  over-allotment
option is  exercised  in full).  The  Company expects  the  net proceeds  to  be
utilized approximately as follows:

- ------------------------
(l) Represents  $2,225,000 principal amount plus accrued interest at the rate of
    10% per annum (estimated at approximately  $93,000 through May 10, 1996)  of
    Bridge  Notes  issued  in the  Bridge  Financing in  December  1995. Certain
    stockholders of the  Company purchased  an aggregate  of $650,000  principal
    amount  of Bridge Notes and two  investment funds in which Lindsay Rosenwald
    is the sole stockholder and President of the general partner and  investment
    manager,  respectively, purchased an aggregate  of $200,000 principal amount
    of Bridge Notes. See "Certain Transactions." The Bridge Notes will mature on
    the completion of the  Offering. The proceeds of  the Bridge Financing  were
    and   are   being  used   primarily  for   working  capital   purposes.  See
    "Capitalization" and "Certain Transactions."
 
(2) Includes (i) $252,500 principal amount borrowed under a working capital bank
    line of credit with Key Bank of New York ("Key Bank"), which bears  interest
    at  the prime  rate plus 2.5%  per annum (10.75%  as of March  31, 1996) and
    which the Company has agreed to repay in 12 monthly installments  commencing
    March  15, 1996 or in full upon the closing of the Offering, (ii) a $124,000
    demand note issued to Key Bank  in February 1995, which note bears  interest
    at  the prime  rate plus 1%  (9.25% as of  March 31, 1996),  the proceeds of
    which were used for working capital purposes, (iii) $460,000 of interest due
    following the closing  of the Offering  on the IDA  Bonds, which amount  has
    been  paid from the Company's debt service reserve funds under the IDA Bonds
    and which  must be  replenished  in accordance  with  the terms  of  waivers
    obtained  from  the  holder of  the  IDA  Bonds and  the  trustee  under the
    applicable indenture, and (iv) $400,000 aggregate principal amount of  notes
    due  on  the  closing of  the  Offering  issued by  the  Company  to certain
    directors, officers  and securityholders  in  March and  May, 1996  to  fund
    working  capital, which  bear interest at  10% per  annum. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operation" and
    "Certain Transactions."
 
(3) Includes, at March 31,  1996, approximately $420,000 past  due more than  30
    but less than 60 days, approximately $190,000 past due more than 60 but less
    than  90 days and approximately  $1,040,000 past due more  than 90 days. The
    Company  has  approximately  an  additional  $950,000  of  accounts  payable
 
                                       17
<PAGE>
    which are less than 30 days past due which the Company intends to pay out of
    funds from operations. In the event such funds are insufficient, the Company
    will  be required  to use  a portion  of the  proceeds allocated  to working
    capital to pay such accounts payable.
 
(4) Includes $2,200,000  for construction  of  a second  melter at  the  Dunkirk
    facility,  which  will  have  the  capacity to  produce  up  to  75  tons of
    ALUMAGLASS per day, and $350,000 for a capital expansion program relating to
    the post-melting abrasives finishing (crushing, sorting and packaging)  area
    at  such facility. The  Company does not  intend to build  the second melter
    until such time  as the  Company's current melter  is running  at near  full
    capacity.  In  the  event  that  prior  thereto  the  Company's  funds  from
    operations are insufficient  to meet its  cash requirements, including  debt
    service obligations, the Company may use the proceeds allocated to build the
    second  melter to fund  its working capital  requirements. See "Management's
    Discussion and Analysis of Financial Condition and Results of Operations."
(5) Includes estimated costs for product applications testing program,  customer
    product  sampling  program,  technical  assistance  program,  telemarketing,
    direct mail and trade journal advertising, sales training, other  activities
    related to the Company's distribution network and other marketing support.
 
(6) Includes   estimated  costs  associated  with  the  Company's  research  and
    development efforts related to  identifying additional applications for  its
    ALUMAGLASS  product line,  identifying synergistic  products or technologies
    that may be available to the  Company through corporate partnering or  other
    opportunities,  research  and  development in  connection  with  its planned
    specialty glass  and glass  ceramic products  and improvements  to  existing
    manufacturing  processes. Pursuant to its  agreement with Alfred University,
    the Company will pay  Alfred University approximately  $164,000 in 1996  for
    certain  research and  development services.  See "Business  -- Research and
    Development."
 
(7) Includes $125,000 that the  Company has the option  to invest to purchase  a
    50% interest in a new company to be jointly owned by the Company and VANGKOE
    Industries,  Inc. ("VANGKOE"), which is intended  to apply color coatings to
    materials purchased from the Company and  sold by VANGKOE. See "Business  --
    Sales and Marketing." Also includes estimated costs associated with locating
    potential sites for new abrasive manufacturing facilities, negotiations with
    potential  strategic partners, researching local regulatory requirements and
    locating and negotiating with local  vendors of raw materials and  potential
    customers.
 
(8) Includes  (i)  accrued  legal and  accounting  expenses not  related  to the
    Offering, estimated  to  be approximately  $356,000,  (ii) $55,000  for  the
    repurchase  by the  Company of  2,455 shares of  Common Stock  from a former
    consultant pursuant  to a  settlement  agreement, which  amount is  due  and
    payable  on the earlier of May 24, 1996 and the closing of the Offering, and
    (iii) approximately $112,000 of principal and  interest due as of April  30,
    1996 to Key Bank and Sullivan Graphics, Inc., which will be repaid following
    the closing of the Offering in accordance with the terms of waivers obtained
    from  such  parties.  The Company  may  also utilize  proceeds  allocated to
    working capital to pay  its approximately $950,000  of accounts payable,  at
    March  31, 1996, that are less than 30 days past due, to the extent not paid
    from funds  from  operations.  Further,  an  additional  $2,200,000  may  be
    available  for working  capital if prior  to the construction  of the second
    melter at the  Dunkirk facility,  the Company  is required  to utilize  such
    funds  to meet  its working capital  requirements. In  addition, the Company
    expects to  use  a substantial  portion  of  the proceeds  of  the  Offering
    allocated  to working capital to fund the debt service obligations described
    below. See "Management's Discussion and Analysis of Financial Condition  and
    Results of Operations -- Liquidity and Capital Resources."
 
    The foregoing represents the Company's current estimate of its allocation of
the net proceeds of the Offering. This estimate is based on certain assumptions,
including  that competitive, regulatory and  market conditions remain stable and
that  demand  for  the  Company's   abrasives  is  sufficient  to  warrant   the
construction of a second melter at the Dunkirk facility.
 
    The  Company  anticipates  that  the  net  proceeds  from  the  Offering and
anticipated  revenues  from  CRT  glass  recycling,  sales  of  ALUMAGLASS   and
mechanical  conversion  services should  be  sufficient to  bring  the Company's
payables current, to construct a second melter at the Company's Dunkirk facility
and to  fund the  Company's operations  for  at least  12 months  following  the
closing  of the Offering.  The Company's fixed expenses  for such period include
approximately $484,000 in  aggregate annual  base compensation  for the  current
executive  officers of the Company and  debt service obligations relating to the
Company's  outstanding   indebtedness,   which  are   estimated   to   aggregate
approximately  $1,647,000 (excluding capital  lease obligations and indebtedness
to be repaid  from the net  proceeds of  the Offering) for  the 12-month  period
 
                                       18
<PAGE>
following  the  closing  of the  Offering.  In  the event  that  in management's
estimation there are not adequate revenues to justify construction of the second
melter at the Dunkirk facility within the 12-month period following the  closing
of  the  Offering,  an  additional  $2,200,000  of  the  net  proceeds currently
allocated for construction of such melter will be available for working  capital
and  other general  corporate purposes. See  "Risk Factors  -- Capital Intensive
Business; Need  for  Additional  Financing"  and  "Management's  Discussion  and
Analysis of Financial Condition and Results of Operations."
 
    The  amounts  actually  expended  for  each purpose  set  forth  in  "Use of
Proceeds" may vary  significantly in the  event any of  these assumptions  prove
inaccurate.  The Company  reserves the  right to change  its use  of proceeds as
unanticipated events  may  cause the  Company  to redirect  its  priorities  and
reallocate  the proceeds accordingly. A portion of the proceeds may also be used
to acquire or invest  in complementary businesses or  products or to obtain  the
right   to  use  complementary  technologies.  Although  the  Company  evaluates
potential acquisitions of  businesses, products  and technologies  from time  to
time,  there  are  no  present understandings,  commitments  or  agreements with
respect to any such acquisitions.
 
    Pending utilization, the net  proceeds of the Offering  will be invested  in
short-term, interest-bearing investments.
 
    Any   additional  proceeds  received  upon  exercise  of  the  Underwriter's
over-allotment option, the Warrants, the Selling Securityholder Warrants or  the
Underwriter's Option will be added to working capital.

    The  following table sets forth the capitalization  of the Company (i) as of
March 31,  1996; (ii)  the pro  forma capitalization  as of  March 31,  1996  to

the closing of  the Offering and  the issuance  of an aggregate  of $200,000  of
promissory notes in May 1996; and (iii) the pro forma capitalization as adjusted
to  reflect  the sale  of the  Shares and  the Warrants  offered hereby  and the
application of the net proceeds therefrom to repay the Bridge Notes and  related
interest  and certain other indebtedness outstanding  prior to the Offering. See
"Use  of  Proceeds."  This  table  should  be  read  in  conjunction  with   the

                                    DILUTION
 
    Dilution represents the difference between the initial public offering price
paid by the purchasers in the Offering and the net tangible book value per share
immediately after completion of the Offering. Net tangible book value per  share
represents the amount of the Company's total tangible assets minus the amount of
its  liabilities, divided by  the number of shares  of Common Stock outstanding,
including the 1,023,054 shares of Common  Stock issuable upon the conversion  of
the  Series A  Preferred Stock upon  the closing  of the Offering.  At March 31,
1996, the Company  had a  negative net tangible  book value  of $(6,071,444)  or
$(3.15)  per common share.  After giving retroactive  effect to the  sale of the
Shares and  the  Warrants  offered  hereby and  the  Company's  receipt  of  the
estimated net proceeds therefrom and the use of a portion of the net proceeds to
repay the Bridge Notes (including related interest) and approximately $1,236,500
of  other indebtedness, the net tangible book value of the Company, as adjusted,
at March 31, 1996  would have been  $6,060,783 or $1.21  per common share.  This
would result in an immediate dilution to the public investors of $3.29 per share
(or  73.1%) and the aggregate increase in the net tangible book value to present
stockholders would be $4.36 per share.
 
    The following table illustrates the information with respect to dilution  to
new investors on a per share basis:

</TABLE>
 
- ------------------------
(1) If  the over-allotment  option is exercised  in full, the  net tangible book
    value after the Offering would  be approximately $1.45 per share,  resulting
    in dilution to new investors in the Offering of $3.05 per share (or 67.8%).

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The  Company is an early-stage specialty materials company currently engaged
in developing, manufacturing  and marketing industrial  abrasives and  recycling
CRT  glass. The Company's initial efforts included developing and seeking patent
protection for its ALUMAGLASS abrasives and establishing its CRT glass recycling
operations. The CRT glass recycling operations commenced prior to the  Company's
abrasives  operations in order  to provide an  initial source of  revenue and to
provide the Company with materials, such as panel glass and sludges, which could
be used as raw materials in the manufacture of the Company's abrasives products.
Dunkirk began receiving CRT glass for recycling in March 1994 and began shipping
recycled CRT glass  to customers  in August 1994  and substantially  all of  the
Company's  revenues  to date  have been  derived from  CRT glass  recycling. The
Company has also derived  minimal revenues to date  from fees charged to  accept
waste  materials and  from the sale  of ALUMAGLASS. Revenue  recognition of fees
charged to accept waste materials is deferred until the materials are resold  or
used by the Company as a raw material.
 
    Although the Company intends to continue its CRT glass recycling operations,
the Company's primary focus has been and will continue to be on the development,
manufacture  and  marketing of  its abrasives.  The  Company's melter  went into
service in February 1995 and went through a shake-down, stress-test and a  final
modification  program. Limited  production of ALUMAGLASS  abrasives commenced in
the spring  of 1995.  Since March  1995  through the  present, the  Company  has
conducted  extensive applications testing for ALUMAGLASS, initiated arrangements
with distributors  for product  marketing, initiated  direct sales  efforts  for
potential  large  volume  customers  and  developed  marketing  and  promotional
strategies for the ALUMAGLASS product  line. Based on its applications  testing,
the  Company believes  that ALUMAGLASS  will provide  performance advantages and
cost savings in comparison to aluminum  oxide, steel grit, glass beads,  plastic
media  and other abrasives. Sales  of ALUMAGLASS to date  have been limited. The
Company has allocated a substantial portion  of the proceeds of the Offering  to
expand its abrasives business.
 
    Since inception through March 31, 1996, the Company has sustained cumulative
losses  of  approximately  $15,164,000.  Such amount  includes  (i)  a one-time,
non-cash charge to operations relating to the write-off in conjunction with  the
Merger  of approximately $6,232,000 for  purchased research and development (in-
process) technologies that had not reached technological feasibility and, in the
opinion of management,  had no  alternative use,  (ii) approximately  $2,308,000
expensed as process development costs related to research and development of the
Company's  CRT glass processing and ALUMAGLASS  abrasives product line and (iii)
other expenses, net of revenue, of approximately $6,624,000. The Company expects
that it will continue to incur losses until such time, if ever, as revenues  are
sufficient to fund its continuing operations. See
"-- Results of Operations."
 
    The  Company has a limited operating history. There can be no assurance that
the Company will ever  achieve or maintain  profitability. The Company  believes
that  the  key variables  and  other factors  which  could affect  the Company's
financial condition  and results  of  operations are  market acceptance  of  its
abrasives  and its ability to continue to  obtain CRT glass and waste streams as
raw materials for the manufacture of its abrasives on cost-effective terms.  The
development  of new technologies to  limit, recycle or dispose  of CRT glass and
waste materials could adversely affect the Company's ability to obtain CRT glass
and other wastes on  cost-effective terms or at  all. The Company only  recently
commenced  sales of ALUMAGLASS and  there can be no  assurance that broad market
acceptance will be achieved. The  Company believes, however, that recent  trends
toward  reusable products  and non-hazardous  products will  increase demand for
ALUMAGLASS because it  is reusable  and, depending  on the  application, can  be
returned  to  the  Company's  melter  for use  in  new  abrasives.  In addition,
ALUMAGLASS has been  formulated to be  safe in use  and handling. Other  factors
important to the success of the Company will be the Company's ability to operate
its   melter  and  other  equipment  with   minimum  downtime  for  repairs  and
maintenance. See "Risk Factors."
 
    Following the Offering, the Company estimates that it will need to  generate
monthly  revenue of approximately $550,000 to  achieve break even cash flow from
operations, based on an estimated cash outlay
 
                                       24
<PAGE>
of approximately $273,000 for cost of goods, approximately $140,000 for selling,
general and administrative expenses and approximately $137,000 for debt  service
at that level of revenue. The Company will attempt to achieve this revenue level
principally  by increasing  sales of  ALUMAGLASS both as  an abrasive  and as an
aggregate and  additive  for  direct incorporation  into  other  materials.  The
Company believes that it can achieve $550,000 of monthly revenue at a production
level  of approximately  16 tons  of ALUMAGLASS per  day assuming  only a modest
increase in  CRT  glass recycling  revenue  from historical  levels  and  modest
revenue  from mechanical conversion. The  Company has recently commenced limited
sales to distributors of ALUMAGLASS and is in discussions with several potential
large volume customers for ALUMAGLASS. Based on the foregoing, the Company hopes
to achieve positive cash flow within six to nine months following the closing of
the Offering, although there can be  no assurance that sales of ALUMAGLASS  will
increase,  that any large volume customers  will purchase ALUMAGLASS or that the
Company will ever generate sufficient revenues to achieve break even cash  flow.
In  addition, the  Company has recently  entered into an  agreement with VANGKOE
which includes a  guaranteed minimum  purchase provision  commencing in  October
1996  (see "Business --  Marketing and Sales").  There can be  no assurance that
VANGKOE will meet  its minimum  purchase obligation  or that  the Company  could
enforce  its rights against VANGKOE, a  newly-formed entity with nominal assets,
in the event of a breach of  such obligation. The Company also believes that  it
can  realize economies of scale that will  reduce costs as a percentage of sales
as its melter is run at consistently  higher output levels and as its  abrasives
finishing area becomes fully operational. These economies are expected to relate
to energy costs, the elimination of duplicative processes and continued focus on
the  Company's batch formulas to  produce the lowest possible  cost of goods. To
the extent that  the Company  experiences economies  of scale  from running  its
facilities at or near full capacity and/or to the extent it can reduce operating
costs, required revenue levels may be reduced.
 
    Until  such time, if ever,  as the Company achieves  positive cash flow from
operations, it will utilize the proceeds of the Offering to fund working capital
needs, including its debt service requirements. The Company anticipates that its
negative cash flow from  operations will be  approximately $150,000 to  $250,000
during  each of the first  two months following the  closing of the Offering and
may decrease over the succeeding months as revenues grow and economies of  scale
are  realized. However,  there can be  no assurance that  the Company's revenues
will ever increase, that economies of scale  will ever be realized, or that  the
Company will ever achieve break even status. However, in the event that revenues
fail  to meet the expected levels required  to achieve break even cash flow, the
Company may  refrain  from  constructing  a second  melter,  and  an  additional
$2,200,000  of  the proceeds  of  this Offering  will  be available  for working
capital. The Company  has not  identified additional  sources of  funds at  this
time,  but  it may  seek a  new  working capital  credit facility  following the
Offering, although it has no commitments to do so at this time. The Company  may
also consider other equity or debt financing strategies in the future to satisfy
its  working  capital  requirements,  although  the  Company  has  no  plans  or
commitments with respect to such strategies at this time.
 
    The foregoing discussion contains  certain forward-looking statements  which
involve  risks  and uncertainties.  The  Company's actual  results  could differ
materially from the results anticipated in such forward-looking statements as  a
result  of the  factors described  herein under  the caption  "Risk Factors" and
elsewhere in this Prospectus.
 
    The Company's workforce recently elected the United Steelworkers of  America
to  act  as  its  bargaining  representative  with  respect  to  their  terms of
employment with  the Company.  The  Company believes  that it  currently  offers
competitive  wages and benefits  and does not  anticipate that negotiations will
have a  material  adverse  effect on  the  Company.  However, there  can  be  no
assurance  that the election of the Union will not result in higher labor costs,
work stoppages or strikes.
 
    The Company has outstanding 740,559 Escrow Shares and 71,923 Escrow  Options
which  will  be released  from escrow  if the  Company attains  certain earnings
levels over the next two to four years or if the Common Stock trades at  certain
levels  over the next three years. The Company will, in the event of the release
of any  Escrow Securities  to the  Company's officers,  directors, employees  or
consultants,  recognize during the  period in which  the earnings thresholds are
met or such stock  levels achieved, a  noncash charge to  earnings equal to  the
fair  value of such  shares on the date  of their release,  which would have the
effect of increasing the Company's loss or reducing or eliminating earnings,  if
any, at such time. The recognition of
 
                                       25
<PAGE>
such  compensation expense may have  a depressive effect on  the market price of
the Company's  securities. See  "Principal Stockholders  -- Escrow  Securities."
Notwithstanding  the foregoing  discussion, there can  be no  assurance that the
Escrow Securities will be released from escrow.
 
    The Company acquired Dunkirk in August 1994 pursuant to the Merger in  which
holders  of Dunkirk common stock received 257,808 shares of the Company's Common
Stock in complete exchange  for their shares of  Dunkirk common stock. Also,  an
aggregate of $269,928 of indebtedness of Dunkirk was exchanged for 13,281 shares
of  the Company's Common Stock in the Merger.  The Merger was accounted for as a
purchase. Prior  to  the  Merger,  Dunkirk  was  a  development  stage  company,
principally  engaged in developing its technologies and building its facility in
Dunkirk, New  York. The  Company was  formed in  June 1993  for the  purpose  of
acquiring  Dunkirk and  conducted no  business prior  to the  Merger, other than
activities  related  to  its  formation  and  initial  capitalization  and   the
consummation of the Merger.
 
RESULTS OF OPERATIONS
 
   NINE-MONTH PERIOD ENDED MARCH 31, 1996 COMPARED TO NINE-MONTH PERIOD ENDED
   MARCH 31, 1995
 
    The  Company's consolidated results of  operations for the nine-month period
ended March 31,  1995 include  only seven months  of the  operations of  Dunkirk
since  the Merger occurred  effective August 31, 1994.  However, for purposes of
the following presentation, the  Company's results of  operations for the  nine-
month period ended March 31, 1995 include the operations of Dunkirk for both the
seven-month  period following the effective date of the Merger and the two-month
period preceding the effective date of the Merger.
 
    The Company had  consolidated revenue  of approximately  $2,077,000 for  the
nine-month  period  ended  March 31,  1996,  consisting primarily  of  CRT glass
recycling  fees  and  approximately  $134,000  of  ALUMAGLASS  sales.  For   the
nine-month  period ended March 31, 1995, the Company had consolidated revenue of
approximately $787,000,  of  which  approximately  $32,000  was  from  sales  of
ALUMAGLASS  and the  remainder was  CRT glass  recycling fees.  This increase in
revenue during the  nine-month period  ended March 31,  1996 primarily  reflects
completion  of the Company's CRT glass recycling operation and the corresponding
increase in the Company's CRT glass  recycling capacity and the commencement  of
the  Company's sales  of ALUMAGLASS. The  Company's revenues from  its CRT glass
recycling operations for the three-month period ended March 31, 1996 were  lower
than  for the prior quarter, primarily  due to adverse weather conditions, which
affected  both  incoming  and  outgoing  shipments,  and  the  effects  of   the
curtailment of certain capital expenditures and wage expenses by the Company. In
order  to conserve cash until  the closing of the  Offering, the Company delayed
replacing certain worn equipment and laid off approximately 10 employees.
 
    Cost of goods sold decreased  to approximately $2,026,000 in the  nine-month
period  ended  March  31,  1996  from  approximately  $2,778,000  for  the  same
nine-month period of the prior year. This decrease reflects a $539,000 reduction
in the Company's  reserve for  potential disposal costs  of raw  materials as  a
result of a decrease in the Company's raw materials inventory as compared with a
$985,000  increase in the  reserve for the  same prior year  period during which
inventories were being built up  in anticipation of production needs.  Excluding
the  effect  of the  change in  the  Company's reserve  for disposal  during the
nine-month periods ended March 31, 1995  and 1996, cost of goods sold  increased
approximately  $772,000 in the  nine-month period ended March  31, 1996 over the
same prior year period. This  adjusted cost increase reflects higher  personnel,
energy,  freight and other  manufacturing costs associated  with the increase in
revenue for the nine-month period ended March 31, 1996.
 
    Selling, general and administrative expenses for the nine-month period ended
March  31,  1996  decreased  to  approximately  $1,213,000  from   approximately
$2,121,000   in  the  same  prior  year  period.  This  decrease  resulted  from
substantially lower  legal, travel,  consulting and  other costs  and a  $99,000
settlement  received from a former officer of Dunkirk during the 1996 nine-month
period.
 
    The Company incurred process development costs of approximately $776,000 for
the nine-month period ended March 31, 1996 as compared with process  development
costs of approximately $982,000 for the
 
                                       26
<PAGE>
same  prior year  period. A decrease  in developmental activity  directed at the
Company's ALUMAGLASS abrasives product during the three-month period ended March
31, 1996  and the  completion of  the Company's  CRT glass  recycling  operation
accounted for this entire cost reduction.
 
    During  the nine-month period  ended March 31, 1995,  the Company incurred a
one-time, non-cash charge to operations relating to a write-off of approximately
$6,232,000, which represented purchased research and development technologies in
conjunction with the Merger that had not reached technological feasibility  and,
in the opinion of management, had no alternative use.
 
    Net  interest expense increased to  approximately $681,000 in the nine-month
period ended March 31, 1996 from approximately $224,000 for the same prior  year
period, reflecting increased indebtedness of the Company.
 
    FISCAL YEAR ENDED JUNE 30, 1995 COMPARED TO FISCAL YEAR ENDED JUNE 30, 1994
 
    For  the fiscal year  ended June 30,  1994 ("fiscal 1994"),  the Company and
Dunkirk were separate (unconsolidated) companies. Dunkirk was in the development
stage and the Company was a holding company, with no investments in  operational
entities.  Neither the  Company nor Dunkirk  realized any  revenue during fiscal
1994. During the fiscal  year ended June 30,  1995 ("fiscal 1995"), the  Company
began  generating revenue and, accordingly, a comparison of operating results of
fiscal 1995 to fiscal 1994 is not meaningful. Fiscal 1995 includes 10 months  of
operations of Dunkirk since the merger transaction occurred effective August 31,
1994.
 
    In  fiscal 1994, the principal expenses  incurred by the Company and Dunkirk
were selling,  general  and  administrative  ("SG&A") costs  in  the  amount  of
approximately $358,000 and $721,000, respectively, and approximately $766,000 of
process  development costs  incurred by  Dunkirk which  represented research and
development costs associated  with the  CRT glass recycling  operations and  the
development  of  ALUMAGLASS  abrasives. The  Company's  SG&A  expenses primarily
consisted of  financing costs  and administrative  compensation. Dunkirk's  SG&A
expenses  primarily consisted of  personnel, consulting, audit  and legal costs.
The Company and  Dunkirk also  incurred net interest  expense on  their debt  of
approximately $13,000 and $26,000, respectively, for fiscal 1994.
 
    The  Company's  consolidated  revenue  for  fiscal  1995  was  approximately
$1,173,000, which  consisted  primarily  of revenue  generated  from  CRT  glass
recycling,  with ALUMAGLASS  sales totaling only  approximately $78,000. Limited
production of ALUMAGLASS did not commence until the spring of 1995.
 
    Consolidated cost of goods  sold for fiscal  1995 amounted to  approximately
$2,789,000,   the  major  components  of   which  were  plant  personnel  costs,
approximately $935,000 in additions to a reserve for potential disposal costs of
raw materials, plus  energy costs  and depreciation  expense. Consolidated  SG&A
costs   for  fiscal  1995  totaled   approximately  $2,529,000,  which  included
consulting, legal  and audit  services,  administrative personnel  costs,  costs
associated  with  initial  abrasives  testing and  marketing  efforts  and other
general  administrative  expenses.  The  Company  also  incurred   approximately
$1,532,000 of process development costs in fiscal 1995, which included costs for
energy  and  utilities,  personnel  and  depreciation  as  they  related  to the
development of the Company's CRT glass recycling services and ALUMAGLASS product
line. The  Company  also incurred  a  one-time, non-cash  charge  to  operations
relating  to  the write-off  of approximately  $6,232,000 relating  to purchased
research and development technologies in  conjunction with the Merger.  Finally,
the Company incurred net interest expense of approximately $346,000 on its debt.
If  Dunkirk had been acquired July  1, 1994, the Company's consolidated revenue,
net loss and pro  forma net loss  per common share  would have been  $1,235,716,
$(12,974,814) and $(17.24), respectively.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The  Company's business  is capital  intensive. The  Company has  funded its
operations principally  from  debt  financing  and the  sale  of  its  Series  A
Preferred Stock. At March 31, 1996, the Company had approximately $11,900,000 in
principal amount of long-term indebtedness (excluding capital lease obligations)
and  a working  capital deficit of  approximately $(7,366,000).  The Company had
approximately $2,600,000 of accounts  payable as of March  31, 1996. As of  such
date,  approximately $420,000 were past due more  than 30 but less than 60 days,
approximately $190,000 were  past due more  than 60  but less than  90 days  and

approximately  $1,040,000 were past due more than 90 days. The Company currently
has negative  cash flow  from operations  averaging approximately  $250,000  per
month  and has been dependent on equity financings and stockholder loans to fund
its  operations.  The   Company's  debt  service   requirements  are   currently
approximately  $412,000  per quarter  (excluding  capital lease  obligations and
indebtedness to be repaid from the net proceeds of the Offering). The  Company's
long-term  indebtedness is  secured by liens  on substantially all  of its fixed
assets.
 
    Dunkirk was initially capitalized by the issuance to its CRT glass recycling
customers of  $535,000 principal  amount  of subordinated  unsecured  promissory
notes  during  the period  from  January 1994  to  March 1994.  An  aggregate of
$535,000 principal amount of such notes, bearing interest at the prime rate plus
2%, were  outstanding as  of March  31,  1996. In  addition, another  CRT  glass
recycling  customer  has  committed  to purchase  subordinated  debt  based upon
shipments to  Dunkirk and,  at  March 31,  1996,  has an  outstanding  principal
balance  of $104,543. Principal on the  subordinated notes is payable in varying
quarterly installments beginning in April 1998 through January 2004.
 
    During the  period  from  June  1994 to  October  1994,  Dunkirk  issued  an
additional  $636,000 principal amount of  promissory notes to quasi-governmental
agencies, of which $535,754 principal amount was outstanding at March 31,  1996.
Of  this amount, $344,258 is a mortgage  note secured by Dunkirk's real property
and the balance are subordinated promissory notes secured by liens on  equipment
of  Dunkirk. Such  notes bear interest  at rates ranging  from 5% to  8% and are
payable in monthly installments through October 2004.
 
    In December  1994  and  January  1995,  Dunkirk  borrowed  an  aggregate  of
$2,585,400  from Key Bank, of which  $2,334,313 principal amount was outstanding
at March 31, 1996, bearing interest at the prime rate. Approximately $398,000 of
the proceeds of the loan  were placed in a segregated  reserve fund to secure  a
portion of the Company's obligations under the loan. The collateral for the loan
is  a first purchase money lien on certain machinery and equipment and repayment
is guaranteed by the New York State Job Development Authority. This debt is also
guaranteed by the Company and Gerald Balcar,  a founder of Dunkirk and a  former
officer  and director of Dunkirk and the Company. The debt is payable in monthly
installments through January 2002. Key Bank has waived principal payments in  an
aggregate  amount of approximately $97,000 due under the loans for the months of
January, February,  March and  April, however,  such amount  is required  to  be
repaid  together with the regularly scheduled principal payments for May, out of
the proceeds of the Offering.
 
    The proceeds  of such  financings  were used  for  working capital  and  the
purchase  of fixed assets.  The promissory notes  and agreements related thereto
contain a limited number of customary covenants and default provisions.
 
    Dunkirk borrowed $386,500 in short-term borrowings from Key Bank during  the
period  from April 1994 to April 1995,  which has been used for working capital,
including $252,500 principal amount outstanding at  March 31, 1996 at the  prime
rate  plus 2.5% under a $300,000 line  of credit arrangement. The line of credit
is collateralized by accounts receivable and inventory and is guaranteed by  Mr.
Balcar.  The borrowings also  include a $124,000  demand note at  the prime rate
plus 1% secured by  a certificate of  deposit owned by Mr.  Balcar. The line  of
credit is repayable over a 12-month period commencing March 15, 1996, or in full
upon the closing of the Offering. The agreements with Key Bank contain a limited
number  of  covenants  and  default provisions.  The  Company  intends  to repay
borrowings under the line  of credit and  the demand note  with proceeds of  the
Offering. See "Use of Proceeds."
 
    In  addition  to  the  foregoing  indebtedness,  in  January  1994,  Dunkirk
purchased its facility from  Sullivan Graphics, Inc.  for $750,000, $475,000  of
which  was paid in subordinated mortgage  notes issued by Dunkirk. The principal
balance of  the  notes  at  March  31, 1996  is  $330,998,  payable  in  monthly
installments  through  February  2004  with  interest  at  10%.  The  notes  are
collateralized by  Dunkirk's  real  property and  contain  normal  covenant  and
default  provisions of a mortgage agreement.  Sullivan Graphics, Inc. has waived
approximately $15,000 of  interest and  principal payments due  under the  notes
which must be repaid on the closing of the Offering.

    In  March and July 1995, Dunkirk issued an aggregate of $8,000,000 principal
amount of IDA  Bonds. Approximately $800,000  of the proceeds  of the IDA  Bonds
were  placed in a segregated  reserve fund to secure  a portion of the Company's
obligations under the IDA Bonds.  The balance of the  proceeds of the IDA  Bonds
have  been used for  capital expenditures including  components of the Company's
current abrasives finishing area capital expenditure program. The IDA Bonds  are
secured  by the fixed assets purchased with  the proceeds thereof. The IDA Bonds
have an interest rate of 11.5%,  subject to downward adjustment if certain  debt
service coverage ratios are achieved. The current quarterly interest payment due
under  the IDA  Bonds is $230,000.  The holder of  the IDA Bonds  has waived the
interest payments due  December 1995 and  March 1996 (and  any event of  default
which  would  otherwise  have  occurred  under  the  applicable  indenture)  and
permitted those payments  to be  made from  the Company's  debt service  reserve
funds.  Such amounts must be replenished within 10 days following the closing of
the Offering.  Principal  repayments commence  in  1998 and  continue  over  the
following 12-year period. The terms of the IDA Bonds restrict Dunkirk's ability,
under  certain circumstances,  to pay  dividends to  the Company.  See "Dividend
Policy."
 
    In April 1994,  the Company  sold $600,000  of convertible  bridge notes  to
certain stockholders of the Company (the "1994 Financing"). The proceeds of such
notes  were used primarily for  working capital. All of  such bridge notes (with
interest) were converted into  45,304 shares of Common  Stock at the closing  of
the Merger.
 
    During  the period commencing  August 1994 and ending  May 1995, the Company
sold an aggregate  of 2,958,000  shares of  its Series  A Preferred  Stock at  a
purchase  price of  $2.50 per share,  all of  which shares will  convert into an
aggregate of 1,023,054 shares  of Common Stock at  the closing of the  Offering.
The  Company received approximately $6,000,000 in  net proceeds from the private
placement, which was used principally for working capital and general  corporate
purposes.
 
    In  September, October and November 1995, the Company issued an aggregate of
$650,000 principal amount of bridge notes to certain of its stockholders to fund
working capital  requirements.  Pursuant  to  the  terms  of  those  notes,  the
principal  amount  of  such notes  was  exchanged  for Bridge  Notes  and Bridge
Warrants in  December 1995.  Accrued interest  on  the notes  was paid  in  cash
following the exchange. See "Certain Transactions."
 
    In  December 1995, the Company consummated the Bridge Financing, pursuant to
which it issued $2,225,000 aggregate principal amount of Bridge Notes (including
the $650,000 referred  to in  the preceding  paragraph) and  Bridge Warrants  to
purchase   an  aggregate  1,112,500   shares  of  Common   Stock.  See  "Certain
Transactions." The proceeds  of the Bridge  Financing, which were  approximately
$1,849,750,  have  been  and are  being  used for  certain  capital expenditures
related to  the Company's  abrasives  finishing area  and working  capital.  The
principal  of  and accrued  interest on  the Bridge  Notes will  be paid  with a
portion of the proceeds of the Offering. A charge in the amount of approximately
$466,000 will occur in  the quarter in  which the Bridge Notes  are repaid as  a
result  of  the  unamortized debt  discount,  debt issuance  costs  and interest
incurred in connection with the Bridge Financing.
 
    In March 1996, the  Company borrowed an aggregate  of $200,000 from  certain
directors,  officers and  securityholders pursuant  to promissory  notes bearing
interest at the rate of 10% per annum, payable on the earlier of the closing  of
the  Offering and September 27, 1996. The  proceeds of such notes are being used
primarily for working capital. In May  1996, the Company borrowed an  additional
$200,000  from one of such securityholders  pursuant to promissory notes bearing
interest at the rate of 10% per annum and payable on the earlier of the  closing
of the Offering and November 1996. See "Certain Transactions."
 
    The Company's capital lease payments were approximately $82,000 for the year
ended  June 30, 1995 and are estimated to be approximately $115,000, $84,000 and
$40,000 for the fiscal years ending June 30, 1996, 1997 and 1998,  respectively,
under  current commitments. The Company's utility expenses average approximately
$65,000 per month. Such amount is expected to increase as the Company's  current
capital expansion program is completed.
 
                                       29
<PAGE>
    From  January 1994 through March 31, 1996,  the Company made an aggregate of
approximately $12,866,000 in capital expenditures. Of such amount, approximately
$1,870,000 was  used in  the  construction of  its  CRT glass  recycling  lines,
approximately   $9,200,000  was  used  in  the  construction  of  its  abrasives
manufacturing operations, including  the pre-melting,  preparation and  batching
area,  the  Company's  melter  and  the  post-melting  abrasives  finishing area
(crushing, sorting and packaging) and approximately $1,796,000 was used for  the
Company's laboratory and other miscellaneous capital expenditures.
 
    The  Company  intends  to  complete  a  capital  expansion  program  to make
improvements and additions  to its  post-melting abrasives  finishing area.  The
Company  expects to use approximately $350,000  of the proceeds of this Offering
for completion of  such program.  These improvements and  additions, which  will
become  operational in phases in 1996, are  anticipated to result in an increase
in the Company's abrasives finishing capacity and will provide further  capacity
for  its manufacturing and  waste conversion operations. At  March 31, 1996, the
Company had capital commitments of approximately $46,000.
 
    Subject  to  achieving  sufficient  demand  for  the  Company's   ALUMAGLASS
abrasives,  the  Company  anticipates  using  approximately  $2,200,000  of  the
proceeds of the Offering  for the construction of  a second melter, which  would
bring abrasives production capacity at the Dunkirk facility to approximately 100
tons  per day. The Company anticipates that construction of such melter could be
completed approximately six months following the  date of order. If the  Company
does  not build  such melter,  an additional $2,200,000  of the  proceeds of the
Offering will be available for working capital and general corporate purposes.
 
    The Company may also seek opportunities within the United States and  abroad
to  construct and  operate additional abrasives  manufacturing facilities, which
may include  CRT glass  recycling operations,  either independently  or  through
joint  ventures or other collaborative arrangements with strategic partners. The
Company expects that future abrasives manufacturing facilities, if any, will  be
financed  through debt issuances  such as the  capital equipment loans described
above and,  in the  case of  on-site  facilities, capital  provided in  part  by
strategic  partners. There can be no assurance that such debt financing or other
collaborative arrangements will be available  on terms favorable to the  Company
or at all.
 
    Certain  of the Company's  contracts with its  CRT customers contain minimum
Company purchase requirements and, in  certain cases, minimum customer  purchase
obligations. See "Business."
 
    The  Company  anticipates  that  the  net  proceeds  from  the  Offering and
anticipated  revenues  from  CRT  glass  recycling,  sales  of  ALUMAGLASS   and
mechanical  conversion  services should  be  sufficient to  bring  the Company's
payables current, to construct a second melter at the Company's Dunkirk facility
and to  fund the  Company's operations  for  at least  12 months  following  the
closing  of the Offering.  The Company's fixed expenses  for such period include
approximately $484,000 in  aggregate annual  base compensation  for the  current
executive  officers of the Company and  debt service obligations relating to the
Company's  outstanding   indebtedness,   which  are   estimated   to   aggregate
approximately  $1,647,000 (excluding capital  lease obligations and indebtedness
to be repaid  from the net  proceeds of  the Offering) for  the 12-month  period
following  the  closing  of the  Offering.  In  the event  that  in management's
estimation there are not adequate revenues to justify construction of the second
melter at the Dunkirk facility, the proceeds of the Offering will be  sufficient
for  the  Company to  remain  in operation,  with  certain modifications  to its
business plan, for at least 12 months following completion of the Offering.  See
"Risk  Factors -- Capital Intensive Business; Need for Additional Financing" and
"Use of Proceeds."
 
    The Company has federal  net operating loss  carryforwards that amounted  to
approximately  $5.8  million  at  June 30,  1995,  including  approximately $1.5
million of net operating loss carryforwards generated by Dunkirk prior to August
31, 1994. Pursuant  to Section  382 of  the Internal  Revenue Code  of 1986,  as
amended (the "Code"), utilization of net operating loss carryforwards is limited
if  there has  been a  change in  control (ownership)  of the  Company. Upon the
merger transaction with  Dunkirk, effective August  31, 1994, such  a change  in
control  (ownership) occurred. As a result  of the change, the Company's ability
to utilize its net  operating loss carryforwards generated  by Dunkirk prior  to
August  31, 1994  (approximately $1.5  million) will be  limited. See  Note 9 of
Notes to Consolidated Financial Statements.
 
    The  Report  of  Independent  Auditors  includes  an  explanatory  paragraph
indicating  that  there is  substantial  doubt as  to  the Company's  ability to
continue as a going concern. See Report of Independent Auditors.

OVERVIEW
 
    The Company is an early-stage specialty materials company currently  engaged
in  (i) developing, manufacturing and marketing industrial abrasives produced in
a patented process utilizing industrial  wastes as raw materials, together  with
certain  virgin materials, and (ii) recycling  CRT glass used in televisions for
sale to the original manufacturers of  such glass and others. Substantially  all
of the Company's revenues to date have been derived from its CRT glass recycling
operations  and, although the Company plans  to continue its CRT glass recycling
operations, the Company's primary focus  is on the development, manufacture  and
marketing  of  its  abrasives.  The  Company  also  utilizes  its  manufacturing
equipment to convert certain types of CRT glass and certain other  manufacturing
by-products  and industrial wastes  into manufacturing raw  materials for use by
the Company in its production of abrasives and for sale to other manufacturers.
 
    The  Company's  initial  abrasives  product  is  its  ALUMAGLASS  brand   of
manufactured abrasives. ALUMAGLASS can be used as a loose grain abrasive applied
with blasting equipment or as an ingredient in products such as polishing agents
and  non-skid flooring.  Blasting of loose  grain abrasives is  used in numerous
industries throughout  the  world  for various  cleaning,  stripping  and  other
surface  treatment or surface preparations applications such as industrial metal
finishing, coating removal, structural steel and commercial vehicle cleaning and
preparations  of  surface  substrates.  The  Company  believes,  based  on   its
applications  testing, that  ALUMAGLASS may  provide performance  advantages and
cost savings in comparison to competitive products such as aluminum oxide, steel
grit, glass  beads, plastic  media  and other  abrasives in  many  applications.
Potential  purchasers  of  ALUMAGLASS  include  military  and  defense agencies,
entities engaged in the electronics,  aerospace, automotive, glass products  and
construction  industries  and  entities engaged  in  surface  finishing, coating
removal and maintenance  of manufacturing and  processing equipment,  buildings,
highways,  bridges  and  commercial  vehicles and  vessels.  ALUMAGLASS  is also
marketed as an aggregate for direct incorporation into products such as non-skid
flooring and  as an  additive for  direct incorporation  into products  such  as
plasters, tiles and other construction materials.
 
    ALUMAGLASS  is manufactured from an alumino-silicate glass which the Company
produces in  a  glass melting  furnace  customized for  the  Company's  patented
process.  The Company's technology enables it to produce such glass utilizing as
raw materials primarily waste products  from the aluminum and other  industries,
including  the electronics  industry with  which the  Company has  established a
relationship through its  CRT glass  recycling. In  many cases,  the Company  is
either paid to take these waste materials or receives them at little or no cost.
The  Company  believes  that  its ability  to  procure  raw  materials utilizing
recycling and recovery techniques will enable it to offer its products at a cost
savings to comparable products for many applications.
 
STRATEGY
 
    The Company's strategy is to focus its efforts on the sale and marketing  of
its ALUMAGLASS product line and, if warranted by market demand for its abrasives
products,  the Company  may use  a substantial  portion of  the proceeds  of the
Offering to increase its manufacturing capacity  by building a second melter  at
its  facility  in Dunkirk,  New York.  The Company  may also  seek opportunities
within the  United  States  and  abroad  to  construct  and  operate  additional
abrasives  manufacturing  facilities,  which  may  include  CRT  glass recycling
operations,  either   independently  or   through   joint  ventures   or   other
collaborative  arrangements  with  strategic  partners. At  the  same  time, the
Company plans to continue its CRT glass recycling business, which it believes is
important to its strategic positioning as a waste conversion company as well  as
its  ability to continue to obtain  raw materials for its manufactured products.
The Company also intends  to utilize certain of  its manufacturing equipment  to
convert manufacturing by-products and other industrial wastes into raw materials
for  use by  the Company  or for  sale to  others. The  Company also  intends to
continue its research and  development efforts to  identify and test  additional
applications  for  its  ALUMAGLASS  abrasives,  to  pursue  the  development  of
processes to  manufacture other  products,  such as  specialty glass  and  glass
ceramics,   utilizing  industrial  waste  as   raw  materials  and  to  identify
synergistic products, services or  technologies that could  be available to  the
Company through acquisition, corporate teaming or other opportunities.

PRODUCTS AND SERVICES
 
    ALUMAGLASS ABRASIVES
 
    The  Company's initial product line is  its ALUMAGLASS brand of manufactured
abrasives. ALUMAGLASS is manufactured  from an alumino-silicate glass,  produced
in  a  patented process  utilizing  commercially available  melting technologies
customized for the Company's manufacturing processes. ALUMAGLASS can be used  as
a  loose grain abrasive applied with  blasting equipment for industrial cleaning
and maintenance and  manufacturing operations  or as an  ingredient in  products
such  as polishing agents and non-skid  flooring. Other product applications are
under development and the  Company believes that  such applications may  include
utilizing  ALUMAGLASS as  a coated  abrasive in  industrial sanding  or grinding
operations. See "-- Market Overview."
 
    The Company's  manufacturing  process  allows it  to  utilize  post-consumer
bottle   glass,  sludges  generated   by  CRT  glass   manufacturers  and  other
manufacturing by-products  and  industrial  wastes  as  raw  materials  for  the
manufacture  of its abrasives. In many cases,  the Company is paid to take these
wastes or receives  them at  little or  no cost.  The Company  has entered  into
supply  agreements to  procure certain of  the waste materials  it receives from
industrial entities. These  agreements set  forth requirements  relating to  the
nature,  composition,  quantity, transportation  and  packaging of  the material
supplied to  the  Company.  These agreements  also  contain  mutual  indemnities
pursuant to which each party agrees to indemnify and hold the other harmless for
breaches by such indemnifying party of its representations and covenants and for
environmental  liabilities  caused  by  such  indemnifying  party.  The  Company
performs batch tests on each delivery to ensure that such requirements are  met.
Material  not meeting specifications is rejected and returned at the generator's
cost.
 
    The Company believes  that the provision  of wastes to  the Company is  less
costly  to its customers  than other regulated  waste disposal alternatives. The
Company  also  believes  that  providing  wastes  to  the  Company  reduces  the
generator's   liability  and  offers  a   pollution  prevention  alternative  to
traditional  waste  treatment  and   disposal  practices.  In  addition,   these
generators  may be eligible to receive  beneficial re-use certification that the
waste material is  used for product  manufacture. In many  situations, this  may
allow  such generators to  claim pollution prevention  credits, by eliminating a
former waste  stream  and providing  it  to the  Company  as raw  material.  See
"Business  -- Environmental Matters." In  certain cases, the Company's abrasives
may also be capable of being reclaimed by the Company after the product is  used
by customers.
 
    The  Company's manufacturing process  gives it the  flexibility to customize
its abrasives to  provide the  various characteristics  required for  particular
applications.   For  example,  by  altering  the   batch  mix  of  raw  material
ingredients, the Company can alter the chemical composition of its abrasives  to
alter   performance  characteristics.  In  addition,  the  Company's  mechanized
finishing area  allows ALUMAGLASS  to  be produced  in  coarse, medium  or  fine
particle  or "grit"  sizes and, with  further processing, into  micro grits. The
Company expects  fine  to medium  grit  ALUMAGLASS to  be  suitable for  use  in
equipment   maintenance  operations,  industrial   process  cleaning  and  other
applications where  the  integrity  of  substrates  is  critical,  such  as  the
maintenance  of turbine blades in power  generation equipment and equipment used
in the aerospace industry. The Company expects medium to coarse grit  ALUMAGLASS
to  be suitable for use in a variety  of cabinet and blast room applications and
as an  ingredient  for  direct  incorporation into  products  such  as  non-skid
flooring. The Company expects coarse grit ALUMAGLASS to be suitable for cleaning
structures  or items having steel substrates  such as bridges, ships, rail cars,
car carriers and cargo containers.
 
    The Company's applications testing efforts to date have focused on utilizing
ALUMAGLASS for  industrial metal  finishing, structural  and commercial  vehicle
cleaning,  paint removal and the cleaning and preparation of other surfaces with
steel or other metal or plastic substrates. Such tests have been conducted by or
at the direction of the Company. Based on the results of such tests, the Company
believes that ALUMAGLASS  provides performance  advantages and  cost savings  in
comparison  to competitive products,  such as aluminum  oxide, steel grit, glass
beads and plastic abrasives, in many applications. For example:
 
    - ALUMAGLASS, unlike many other abrasives, is angular, with sharp edges. The
      product fractures when blasted, continually yielding sharp edges for reuse
      until consumed. As a result, the product offers superior speed of cleaning
      and less of it is required.
 
                                       32
<PAGE>
    - ALUMAGLASS is a relatively hard  abrasive, suitable for many  applications
      where metallic abrasives, such as steel grit and aluminum oxide, are used;
      however,  ALUMAGLASS  has  a  relatively  low  specific  gravity requiring
      significantly less energy to compress air for blasting the product.
 
    - ALUMAGLASS requires no  special health and  safety equipment for  blasting
      personnel.  Because it is lighter in weight and blasted at lower pressures
      than heavy abrasives,  it is  safer for  operators to  use when  deploying
      blast  hoses  and creates  less wear  and tear  in blasting  equipment. In
      addition, compared  to metallic  abrasives  blasted at  higher  pressures,
      there  is less risk  of sparking, which  may cause fires  or explosions in
      sensitive applications such as petrochemical or refining operations.
 
    - As an ingredient in non-slip,  non-skid flooring applications, the  higher
      particle  density of ALUMAGLASS compared  to metallic abrasives results in
      approximately 30%  less ALUMAGLASS  being  required for  comparable  jobs.
      ALUMAGLASS  is also typically less  expensive than products typically used
      such as aluminum oxide.
 
    - While results  may  vary  depending  upon the  blast  conditions  and  the
      substrate  being blasted, ALUMAGLASS typically  yields a comparable number
      of reuse cycles compared to aluminum oxide and glass beads, although steel
      grit  and  plastic  abrasives  typically  yield  more  reuse  cycles  than
      ALUMAGLASS. However, because ALUMAGLASS will not rust, it may exceed these
      reuse   cycles  and  be   more  effective  than   steel  grit  in  certain
      applications, such  as  outdoor  steel blasting  operations  in  humid  or
      coastal areas.
 
    - Unlike  metallic abrasives, ALUMAGLASS typically  will not become embedded
      in metal substrates where  a hard abrasive is  required. This negates  the
      need for subsequent surface preparation treatment.
 
    - ALUMAGLASS  is an alumino-silicate glass, rather than a metallic abrasive.
      Therefore, ALUMAGLASS can be used in applications where softer  abrasives,
      such  as glass beads and plastics, are  used. When used at the recommended
      blasting pressures, ALUMAGLASS creates the fine surface finishes of  these
      competing  softer abrasives and works faster. ALUMAGLASS is less expensive
      than plastic  abrasives,  although  typically more  expensive  than  glass
      beads.  In many  glass bead  applications, however,  customers blend glass
      beads  with  aluminum  oxide  to  achieve  desired  cleaning  and  surface
      preparation  results and ALUMAGLASS is  typically less expensive than such
      composites.
 
    RECYCLING OF CRT GLASS
 
    The Company  is engaged  in recycling  CRT glass  used in  televisions.  The
Company's  CRT glass recycling customers  include electronics manufacturers such
as  Techneglas,  Inc.,  Thomson  Consumer  Electronics,  Inc.,  Toshiba  Display
Devices,  Inc. and Hitachi Electronic Devices, U.S.A., Inc. In the Company's CRT
recycling operations, waste  CRT glass,  or "dirty  cullet," is  shipped to  the
Company  by  its  customers  pursuant  to  agreements  with  the  Company. These
agreements provide that the Company  is to be paid a  fee for receiving the  CRT
glass. Certain of the Company's contracts with its CRT customers contain minimum
Company  purchase requirements and, in  certain cases, minimum customer purchase
obligations. The Company receives  both funnel glass (the  back of a  television
screen,  which is  relatively thin  and tubular in  shape) and  panel glass (the
front of a television screen, which is relatively thick and flat in shape).  The
funnel  glass is cleaned, separated and  sold back to the original manufacturers
and others. The panel glass is cleaned, separated and sold as a raw material  to
the  original manufacturers and others or used  as a raw material by the Company
in the production of its ALUMAGLASS abrasives.
 
    The Company  employs  a  CRT  glass recycling  system  utilizing  a  sorting
technology for which the Company has filed a joint patent application with Asoma
Instruments,  Inc. of Austin, Texas ("ASOMA"). The sorting technology uses X-ray
fluorescence to identify and sort CRT glass by chemical composition. The Company
and ASOMA are joint owners of the patent application and any patent that issues,
and neither the Company nor ASOMA can grant licenses of such patent without  the
consent  of the other party.  In the event that  either party grants any license
with respect to such patent to a  third party, 66-2/3% of the royalties will  be
paid to ASOMA and 33-1/3% of such royalties will be paid to the Company.

<PAGE>
    CRT  glass fragments  received by the  Company of approximately  one inch or
less in diameter are not currently recycled by the Company due to limitations of
its X-ray fluorescence technology. The Company is currently in discussions  with
potential  customers  to  purchase such  glass  and,  although there  can  be no
assurance, believes that  it can  sell such glass  at prices  acceptable to  the
Company.  In the event the Company is unable  to sell such glass, it believes it
can dispose of such glass  at little or no cost  by delivering it to others  who
use various glass materials in the manufacture of their products or the products
of  others.  The Company  also believes  that it  can dispose  of such  glass in
landfills at prevailing rates. The Company maintains a reserve for the potential
cost of  disposing  of  CRT  glass  it  is unable  to  recycle  or  use  in  its
manufacturing  process. Such reserve is adjusted  periodically for the amount of
such material on-hand, landfill rate  changes and management's determination  of
the  need for any such reserves based upon the proven saleability or disposition
options for such materials.
 
    Through March 31, 1996, CRT glass recycling has accounted for  substantially
all  of the Company's revenues.  The Company's initial sources  of CRT glass for
recycling  have  been  television  manufacturers,  who  provided  financial  and
technical  support to the Company. The  Company also approached certain computer
manufacturers early in its operations, but such manufacturers indicated a desire
for the Company's CRT glass recycling  operations to be fully operational  prior
to  considering sending  their glass  to the  Company. The  Company has recently
contacted these  and  other manufacturers  as  well as  disassemblers  of  post-
consumer  televisions and computers to seek to enter into arrangements to obtain
CRT glass from them. There can be no assurance that the Company will enter  into
arrangements  with such manufacturers  on terms acceptable to  the Company or at
all.
 
    The Company believes  that the recycling  of CRT glass  is important to  its
strategic  positioning and to  its overall relationship  with its customers. The
Company believes that the recycling of  CRT glass provides its customers with  a
less costly and more environmentally responsible means of disposing of waste CRT
glass compared to currently available alternative methods of CRT glass disposal.
Further,  customers  can repurchase  recycled CRT  glass from  the Company  at a
savings  compared  to  virgin  ingredients.  Based  upon  discussions  with  its
customers,  the  Company  believes that  the  purchase price  for  the Company's
recycled glass may  be up  to 30%  less than the  cost of  virgin materials.  In
addition,  the Company is able  to utilize certain types  of CRT glass which are
not recycled as raw materials for ALUMAGLASS  and may be able to use such  glass
for  its specialty  glass products under  development. In  addition, the Company
believes that the electronics industry may be a source of other waste streams as
raw materials  in the  Company's abrasives  and planned  glass-ceramics  product
lines.  The Company believes that relationships with its CRT glass customers may
serve as a catalyst for the  development of new facilities, including  potential
facilities  to serve CRT  glass recycling needs where  landfill laws restrict or
ban landfill disposal of  televisions and computers.  The Company believes  that
its  CRT glass recycling and materials reuse capability positions the Company to
process large  volume end-of-life  television  and computer  waste if  and  when
regulation excludes them from U.S. landfills.
 
    MECHANICAL CONVERSION
 
    The  Company  utilizes its  post-melting  abrasives finishing  equipment and
know-how to convert manufacturing by-products and waste glass and ceramics  into
raw materials for use by the Company in its manufacture of abrasives or for sale
to  others. Examples include the cleaning,  sorting and grinding of waste bisque
otherwise used for china as a source  of alumina for the Company's abrasives  or
for  sale to others as a raw material, and the cleaning, sorting and grinding of
soda lime  glass as  a raw  material for  the Company's  abrasives or  as a  raw
material  for  glass producers.  The Company  intends  to use  a portion  of the
proceeds of this Offering to  expand its post-melting abrasives finishing  area,
thereby   increasing  the  Company's  capacity  to  mechanically  convert  waste
materials into raw material for the  Company or others. The planned increase  in
the  Company's abrasives finishing capacity will provide additional capacity for
the crushing, grinding and packaging of materials which other manufacturers  can
utilize as raw materials for their manufacturing processes.
 
    The  Company believes that there  may be demand for  these services and will
devote  additional  resources  to  identifying  these  materials  and   locating
customers  for these  services after  the Offering.  The Company  has engaged in
discussions with several manufacturers of glass and glass-ceramic products  that
may be interested
 
                                       34
<PAGE>
in  purchasing crushed, screened and packaged  china bisque, soda lime glass and
CRT panel glass from the Company. The Company has made initial test shipments of
such products to  several customers  and has itself  developed a  number of  end
product  applications for these  materials, such as  the Company's planned glass
bead product.
 
    POTENTIAL FUTURE PRODUCTS
 
    SPECIALTY GLASS.    The Company's  first  potential future  product  in  the
specialty  glass  area is  a glass  bead to  be  made in  part from  panel glass
received by the Company from its CRT glass recycling customers. Such panel glass
would be crushed in the Company's post-melting abrasives finishing area and then
used as a raw material, together  with other materials, in the manufacturing  of
the  glass  bead.  The  Company  believes  that  such  beads  will  have  a high
retroreflective index  and greater  durability and  elasticity, expected  to  be
useful  in applications which include surface  finishing and highway signage and
possibly pavement  marking. The  Company  has filed  a patent  application  with
respect  to the formulation  and production of such  glass beads, although there
can be no assurance  that such patent  will issue. The  Company is currently  in
discussions  with several established  companies in the  glass bead business and
may determine to enter into a  joint venture or other collaborative  arrangement
with  a corporate partner in order to  pursue the commercial development of this
product. The  Company may  attempt  to develop  other specialty  glass  products
including  frit  for  electrical  resistance glass,  decorative  glass  and high
density glass.
 
    GLASS-CERAMICS.  The Company plans to evaluate the production of a series of
high-strength, low-weight  glass-ceramic products  using waste  materials to  be
provided  through  its relationships  with the  specialty steel  and electronics
industries and other industries generating silica and metals-enriched industrial
wastes. The  Company  believes  that,  combined  with  virgin  materials,  these
products  have potential uses as substitutes for structural materials, including
steel, in the aircraft, automotive,  construction and machinery industries.  The
Company  also believes that ALUMAGLASS particles  may be sold as ingredients for
direct incorporation into products such  as floor tiles, glass-ceramic  powders,
plastic  fillers and other ceramic  product applications. These applications may
be pursued independently or  through joint venture  or cooperative efforts  with
others.
 
    OTHER  ABRASIVE PRODUCTS.  The Company expects to develop future products in
its core  abrasives business.  Such  products may  include (i)  higher  strength
abrasives  which  may  be  produced  utilizing  new  formulations,  (ii) blended
composites of ALUMAGLASS and other abrasive materials, (iii) products  utilizing
ALUMAGLASS as a coated abrasive on sandpaper, grinding wheels or other items and
(iv)  abrasives such as crushed glass  produced through the Company's mechanical
conversion processes.
 
    No assurance can be given that the Company will be successful in  developing
any  future  products  or that  it  will be  able  to market  any  such products
successfully.
 
MANUFACTURING, RECYCLING AND CONVERSION PROCESSES
 
    ABRASIVES MANUFACTURING PROCESS
 
    The Company's  abrasives are  manufactured in  a three-step  process --  the
pre-melting,   batching  process,  the  melting  process  and  the  post-melting
finishing process.
 
    PRE-MELTING, BATCHING PROCESS.   The pre-melting, batching process  includes
the  collection  and intake  of materials  such  as post-consumer  bottle glass,
sludges produced  in  the  manufacture  of CRT  glass  and  other  manufacturing
by-products  and industrial wastes,  as well as certain  virgin materials, to be
used as raw materials for the  Company's abrasives. Various alumina, silica  and
certain  other metal or calcia-enriched  manufacturing by-products and wastes of
the electronics, aluminum, specialty steel, automotive and other industries have
been identified  and utilized  by the  Company as  product ingredients  for  its
manufacturing  processes.  The Company  has entered  into supply  agreements for
certain of the  materials with  industrial entities,  and secured  authorization
from  applicable environmental  regulatory authorities to  utilize various waste
materials as product ingredients. Other virgin and waste materials are available
on a  purchase  order basis.  The  Company's  procedures to  secure  wastes  for
beneficially utilized production ingredients in its
 
                                       35
<PAGE>
manufacturing  process has  been determined to  be exempt  from RCRA regulation,
enabling the Company to utilize these materials without subjecting itself to the
financial and  operational constraints  typically  imposed on  waste  management
facilities. See "Business -- Environmental Matters."
 
    Once collected, raw materials are loaded into bins or otherwise separated so
that  specified  quantities of  each  material can  be  assembled pursuant  to a
computerized batching system  for which the  Company has been  issued a  patent.
Once a batch of raw materials having the desired chemical components, consisting
principally of soda, silica, alumina and calcia, has been assembled, it is taken
to the Company's melter for the next phase of manufacture.
 
    MELTING  PROCESS.   Each  mixed batch  of  raw material  is loaded  into the
Company's melter  in  order to  produce  the alumino-silicate  glass  comprising
ALUMAGLASS.  The Company's  melter is  a customized  glass melting  furnace. The
melter employs a customized air emissions scrubber and heat exchange  technology
that  reduces harmful  solid or  liquid residual waste  or air  emissions in the
production process. Certain emissions captured  in the scrubber are returned  to
the  melter for use as raw materials. The alumino-silicate glass produced in the
melter is cooled, where it  forms hard particles or "frit"  and is taken to  the
abrasives finishing area.
 
    The melter went into service in February 1995 and went through a shake-down,
stress-test and a final modification program to bring its production capacity to
25  tons of ALUMAGLASS per day, although there  can be no assurance that it will
maintain such  capacity  consistently.  From  time  to  time,  the  Company  has
experienced  mechanical or  technical difficulties  with such  melter which have
required repairs and maintenance that have interrupted the Company's ability  to
manufacture  its  abrasives.  In early  1995,  the melter  did  not successfully
oxidize a sludge being tested, which resulted in the formation of a thick  glass
that  clogged the pouring area. The melter had to be flushed with soft glass for
five  days  before  returning  to  normal  production.  In  November  1995,  the
repositioning of air bubblers used to speed the flow of glass resulted in a leak
because  of increased wear on a relatively  soft area of the melter's refractory
brick floor. The  Company took  the melter  out of  service for  three weeks  to
replace  and fortify  the area, to  make additional planned  improvements and to
conduct a full examination of the  melter. Such examination showed minimal  wear
in other parts of the melter. The Company estimates that the melter will have to
be  taken out of service approximately once every four years for approximately a
three-week  period  to  replace  worn  refractory  bricks,  which  is   required
maintenance   for  glass   melters  generally.   Any  mechanical   or  technical
difficulties with the melter  in the future could  result in an interruption  in
the  Company's ability to manufacture its  abrasives. The failure of the Company
to effect prompt  repairs and otherwise  keep its melter  operating at  targeted
capacities  could  have a  material adverse  effect  on the  business, financial
condition and results of operations of the Company.
 
    If warranted  by  demand  for  the Company's  abrasives,  the  Company  will
construct a second melter expected to have the capacity to produce approximately
75 tons of ALUMAGLASS per day. The Company has allocated a substantial amount of
the  proceeds of the Offering  for the construction of  such melter. The Company
believes that there  are a number  of potential suppliers  of glass melters  and
other  furnaces. The Company believes that a 75-ton-per-day unit can provide the
Company with economies of scale in both capital and operating costs. See "Use of
Proceeds" and "Management's Discussion and  Analysis of Financial Condition  and
Results of Operations." In addition, if sufficient levels of demand are achieved
in  certain areas of the United States or  abroad, the Company may seek to build
additional facilities to manufacture its abrasives, which may include CRT  glass
recycling  lines. These facilities may be developed independently by the Company
or pursuant to arrangements with corporate  partners such as large volume  users
of loose grain abrasives such as shipyards or large heavy-industry corporations.
These  entities may have many of the desired waste items on hand and may require
volumes of the  abrasives that  justify on-site construction  to avoid  shipping
costs.  Any excess  capacity of  such facilities could  be used  for third party
sales. It is  anticipated that  the construction  of these  facilities would  be
financed  with debt, with an equity component to be provided by the Company and,
if applicable, its corporate partner.
 
                                       36
<PAGE>
    POST-MELTING FINISHING PROCESS.  The  post melting abrasives finishing  area
consists  of various items of equipment  which perform the functions of crushing
ALUMAGLASS frit  to desired  sizes, sieving  the crushed  frit to  separate  the
particles  and, once  the ALUMAGLASS  has been tested  to assure  "grit" size is
consistent with industry standards, packaging ALUMAGLASS for sale to customers.
 
    The  abrasives  finishing  area  currently  has  a  production  capacity  of
approximately 15 tons per day for coarse grit sizes and lower volumes for medium
and  fine  grit  sizes.  However,  the Company  intends  to  complete  a capital
expansion program to make improvements and additions to its finishing area which
is expected to result  in a three-to four-fold  increase in finishing  capacity.
See  "Management Discussion  of Analysis of  Financial Condition  and Results of
Operations." The Company also utilizes  the abrasives finishing area to  convert
certain  manufacturing  by-products and  other  materials it  receives  into raw
materials for its abrasives and for sale to others.
 
    The Company believes that the cost-effectiveness of the Company's  abrasives
manufacturing processes resulting from its ability to utilize waste materials or
raw  materials  will  provide significant  competitive  advantages.  The Company
enjoys further operating cost advantages compared to competitors in that certain
of the waste materials  used in the production  of ALUMAGLASS provide a  British
Thermal  Unit  or "BTU"  value which  lowers the  Company's energy  costs, which
typically are a major cost component of glass and glass-ceramics production.  In
addition,  the Company expects its products to be classified as "recycled" under
applicable guidelines of the United States Environmental Protection Agency,  and
accordingly  to achieve  preferential procurement  status. The  Company believes
that such classification may be significant to users who express a preference or
provide  special   procurement   consideration  for   recycled   products.   See
"Environmental Matters."
 
    CRT GLASS RECYCLING PROCESS
 
    The  first step in the recycling of CRT glass is the inspection of the glass
received by the Company to assure  that it complies with requirements set  forth
in  purchase and  supply agreements  between the  Company and  its CRT customers
relating to the nature  of the glass, amounts  of extraneous materials mixed  in
with  the glass and  other requirements. Such  inspection is generally conducted
manually, but may involve the use  of hand held devices which identify  chemical
constituents  of CRT glass. Nonconforming shipments are rejected and returned to
the supplier at the supplier's expense.
 
    Once accepted, CRT glass is processed through the Company's "primary" cullet
line. The  process  involves extracting  pieces  of CRT  glass  of less  than  a
specified  size, separating the panel glass  from the funnel glass, cleaning and
removing coatings  on the  glass, identifying  the chemical  composition of  the
panel glass by use of X-ray fluorescence and batching the funnel glass and panel
glass  for resale  back to  customers. This  process is  repeated for  CRT glass
fragments  too  small  for  the  Company's  primary  cullet  line  by  identical
processing  through the Company's  "secondary" cullet line.  CRT glass fragments
received by the Company of  approximately one inch or  less in diameter are  not
currently  recycled by the Company due  to limitations of its X-ray fluorescence
technology.
 
    MECHANICAL CONVERSION PROCESS
 
    The  Company  has  identified  several  waste  streams  which  it  receives,
including  post-consumer bottle glass,  bisque used to make  china and CRT panel
glass, as materials which, if converted from the form in which they are received
by the Company into a form suitable to be used as a manufacturing raw  material,
become  valuable materials independent  of the Company's  recycling or abrasives
manufacturing operations. The Company identifies the chemical or other  valuable
properties  of these materials and identifies third parties that can utilize the
materials in their  manufacturing or  other operations. Then,  depending on  the
customer's  needs, the Company utilizes its equipment, principally its recycling
lines and post-melting,  abrasives finishing  equipment, to  sort, clean  and/or
grind  and  crush the  material  into the  desired  form. The  material  is then
packaged and shipped to customers.
 
    The Company also has the ability to make composite materials, if  requested,
by  mixing  the  waste  material  being converted  with  other  waste  or virgin
materials. The Company  also uses  its equipment to  mechanically convert  these
materials  into  a form  suitable for  use as  a raw  material in  its abrasives
production.
 
                                       37
<PAGE>
RESEARCH AND DEVELOPMENT
 
    The  Company's research  and development  efforts are  conducted principally
through (i) the Company's internal staff,  (ii) the Center for Advanced  Ceramic
Technology  at Alfred  University pursuant  to agreements  with the  Company and
(iii) the Company's Scientific Advisory Board.
 
    The Company  currently  employs  five  individuals  principally  devoted  to
research   and  development,  including,  among  others,  Robert  Dejaiffe,  the
Company's Vice President-Technology, Dr. Ashvin Srivastava, Director of Research
at Dunkirk, and Dr. Kimberly Lotter, Laboratory Director at Dunkirk, all of whom
have extensive experience in glass  and ceramic technologies. See  "Management."
The  Company  maintains  an on-site  laboratory  at its  Dunkirk  facility where
various analyses,  tests  and  other research  and  development  activities  are
conducted on a regular basis.
 
    The Company has entered into a research agreement (the "Research Agreement")
with  The Center for Advanced Ceramic  Technology at Alfred University ("CACT"),
pursuant to  which CACT  performs various  tests and  studies on  behalf of  the
Company,  as directed by the Company. CACT is the Company's primary research and
development partner.  CACT  is  currently  engaged  in  a  study  of  the  basic
characterization of ALUMAGLASS. The Research Agreement expires in December 1996.
Under the Research Agreement, the Company is obligated to pay CACT an amount not
to  exceed $163,728 for the  term of the Agreement.  Payments are made quarterly
based on a  budget approved in  advance by the  Company. The Agreement  provides
that  royalties or other consideration received from a third party from the sale
or licensing  of any  patents developed  pursuant  to the  Agreement are  to  be
divided  equally  between  CACT and  the  Company,  except that  the  Company is
entitled to all royalties received from  third parties in which the Company  has
an equity interest of 20% or more. Individuals at CACT were also involved in the
development  of the  Company's abrasives  manufacturing process  and the related
patent, but assigned their  rights thereto to the  Company. Richard M.  Spriggs,
Ph.D.,  the Chairman of the Company's Scientific Advisory Board, is the Director
of CACT.  The  Company  also  engages other  academic  institutions  to  provide
specific research and development services from time to time.
 
    The  Company also  utilizes its Scientific  Advisory Board  for research and
development activities such  as advising as  to potential product  applications,
the   feasibility  of  new  product  formulations  and  the  impact  of  process
modifications on product characteristics. See "Management -- Scientific Advisory
Board."
 
    The Company co-developed the X-ray fluorescence technology for its CRT glass
recycling operation with ASOMA, with respect to which the Company and ASOMA have
filed a joint patent  application. The Company  may pursue other  co-development
opportunities with third parties in the future or look to others for licenses of
technology  or  other  arrangements,  although  the  Company  has  no  plans  or
commitments to do so as of the date of this Prospectus.
 
    The Company will continue its  research and development efforts to  identify
additional  applications for its ALUMAGLASS abrasives, to pursue the development
of processes to manufacture other products and to identify synergistic products,
services or  technologies  that  could  be  available  to  the  Company  through
acquisitions,  corporate teaming  or other  opportunities. The  Company believes
that there  are  many  environmentally  oriented  manufacturing  and  processing
technologies  that are in early stages of commercialization and development that
could provide synergies with the Company's technologies through licensing, joint
ventures, acquisitions or otherwise.
 
MARKET OVERVIEW
 
    ABRASIVES
 
    Traditionally, a variety of  media and methodologies have  been used in  the
broad market of industrial equipment and facilities cleaning and maintenance. In
particular, sand used in blasting applications and chemical solvents have held a
significant share of the market. In recent years, however, increased regulations
relating  to the environment  and worker health  and safety, have  resulted in a
dramatic decline in the use  of sand, which is known  to contribute to the  lung
disease  silicosis.  In  addition,  given  the  greater  demand  for reclaimable
abrasives, which  reduce  the  amount  of spent  abrasive  material  subject  to
landfill  and  potential  environmental  liability,  the  Company  believes that
non-reclaimable abrasives, such as sand and metal slags,
 
                                       38
<PAGE>
are competitively disadvantaged.  Chemical solvents have  also decreased in  use
with  respect to many applications due  to such regulatory changes, particularly
regulations which have resulted  in increased disposal  costs. Products such  as
ALUMAGLASS,  glass  beads  and  mineral,  metallic  and  plastic  abrasives, are
affected to a  lesser extent  by such  regulations due  to the  nature of  their
composition  and the fact that they are reclaimable for multiple uses and have a
lower quantity for disposal. ALUMAGLASS,  for example, contains no free  silica,
which  causes silicosis, and,  depending on the application,  can be recycled by
the Company at  its Dunkirk facility  rather than disposed  of after use.  Other
approaches  such  as water  blasting are  also  gaining acceptance.  The Company
believes that  this  regulatory framework,  as  well as  the  other  performance
advantages   offered  by  its   abrasives,  will  result   in  increased  market
opportunities for ALUMAGLASS.
 
    Loose grain abrasives, typically applied  with blasting equipment, are  used
in  numerous  industries  throughout  the  world  for  equipment  and facilities
maintenance.  Applications  include  cleaning,   stripping  and  other   surface
treatment   or  surface  preparation  applications,  such  as  industrial  metal
finishing, coating removal,  structural steel and  commercial vehicle  cleaning,
paint  removal and the cleaning and preparation of service substrates. Potential
purchasers of the  Company's abrasives  include military  and defense  agencies,
entities  engaged in the electronics,  aerospace, automotive, glass products and
construction industries  and  entities  engaged in  surface  finishing,  coating
removal  and the maintenance  of manufacturing and  process industries equipment
and  facilities,  buildings,  highways,  bridges  and  commercial  vehicles  and
vessels.
 
    Industrial  abrasives can also be  directly incorporated into other products
such as non-skid flooring, sand paper, grinding wheels and polishing  compounds.
Abrasives  are  mixed  with  cement and  paints  to  provide  non-skid surfaces.
Abrasives are applied as a coating on plastic wood. Abrasives are also used  for
applications  such as softening leather, stonewashing  denim and shot peening to
remove metal fatigue found in aircraft.
 
    The Company  believes that  ALUMAGLASS provides  performance advantages  and
cost savings compared to competing abrasive products and that ALUMAGLASS will be
able to obtain significant market acceptance through the Company's marketing and
sales  efforts. See "-- Products and Services," "-- Sales and Marketing" and "--
Competition." To some degree, the cost advantages associated with ALUMAGLASS are
derived from  the  Company's ability  to  obtain  industrial wastes  to  use  as
manufacturing  raw  materials at  little  or no  cost.  To the  extent  that the
suppliers of  such wastes  utilize alternative  means of  disposal, the  Company
would  be required  to purchase  virgin materials  for use  as manufacturing raw
materials.  However,  the  Company  believes  that  adequate  supplies  of  such
materials   would  be  available  to  the  Company  on  satisfactory  terms  and
conditions, including cost.
 
    There can be no  assurance that ALUMAGLASS  will achieve market  acceptance.
The  decision by  a potential  customer to  utilize the  Company's abrasives is,
among other  things, technical  in nature,  requiring the  customer to  make  an
evaluation  as  to  whether  changes  in  its  capital  equipment  or  operating
procedures will be required in order to realize the performance benefits of  the
Company's  products. The primary capital equipment change that could be required
relates to equipment used to reclaim abrasives. ALUMAGLASS has been designed  as
a  reclaimable abrasive that can  be reused between five  and ten times during a
single  application.  Current  techniques  to  reclaim  abrasives  and  separate
contaminants  from the  abrasive include gravity  separation, cyclone separators
and  air  classifier  systems.  Of   these,  gravity  separation  is   typically
inappropriate  for ALUMAGLASS due  to the relatively  light weight of ALUMAGLASS
compared to the  contaminants to  be removed.  Thus, a  potential customer  with
gravity  separation equipment may have to  replace such equipment with a cyclone
separator or air classifier at a cost that the Company believes would range from
$20,000 to $50,000,  depending on the  size of the  unit. The primary  operating
procedure  change  that potential  customers  must employ  is  reducing blasting
pressure for ALUMAGLASS by  20% to 30% compared  to pressures used for  heavier,
metallic  abrasives. There  can be  no assurance  that potential  customers will
choose to change  their equipment  or established  procedures or  be willing  to
incur any necessary costs to make such changes or that the benefits derived from
utilizing ALUMAGLASS will outweigh the costs incurred to make such changes.

    CRT GLASS RECYCLING
 
    The  Company currently recycles only waste CRT glass generated by television
manufacturers located in the United States. There are several manufacturers from
which the Company  does not receive  glass and it  does not receive  all of  the
waste glass produced by its current customers. Such manufacturers typically seek
more  than one outlet for  their CRT glass, in order  to avoid dependence on any
one source. In some cases, manufacturers ship their waste CRT glass to  smelters
or  landfills.  Therefore,  the  Company  believes  that  there  is  some growth
potential for its CRT  recycling operations. However,  such market, as  narrowly
defined,  is limited by  the relatively few manufacturers  located in the United
States, the relatively low percentage of CRT glass which becomes waste prior  to
being  incorporated into  televisions and  shipping costs  associated with doing
business with manufacturers located at significant distances from the Company.
 
    The Company  also  plans to  expand  its  CRT glass  recycling  business  by
recycling  waste CRT glass  generated by manufacturers  of computer monitors and
post-consumer CRT glass obtained from entities engaged in television or computer
disassembly as discussed below. However, the Company does not currently have any
commitments to take such glass  and there can be  no assurance that the  Company
will enter into any arrangements to do so.
 
    Additional  large markets for  CRT recycling are  presented by post-consumer
television  and  computer  monitor   glass.  However,  such  business   involves
disassembly  which is  currently a manually  intensive operation and  may not be
commercially viable for  the Company.  The Company  may enter  this business  by
obtaining  CRT glass  directly from entities  engaged in  television or computer
disassembly. In  addition,  the  Company  has  from  time  to  time  engaged  in
discussions  with potential strategic  partners with respect  to a co-venture to
enter this business  but has  no commitments to  do so  as of the  date of  this
Prospectus.  The Company believes that this may  be a large market in the future
as environmental regulations move toward  banning or significantly limiting  the
amount  of such  glass which can  be disposed of  in landfills. There  can be no
assurance that the  Company will be  able to enter  this market on  commercially
acceptable terms or at all.
 
    MECHANICAL CONVERSION
 
    The Company believes that the U.S. demand for the Company's waste conversion
services  as part  of its  manufacturing process  will be  driven by industries'
needs to remove and  manage manufacturing by-products  and industrial wastes  in
compliance  with  various federal,  state and  local environmental  statutes and
regulations. See  "--  Environmental Matters."  Other  industrialized  countries
around  the world are  also proposing or  enforcing similar, and  in some cases,
more stringent  environmental legislation.  Consequently, the  Company  believes
that  demand for the Company's waste conversion services may increase because of
anticipated, increasingly stringent environmental  regulations and the  concerns
of waste generators over accompanying waste disposal liabilities in the U.S. and
abroad.  The Company's  competitive advantage and  successful market penetration
will depend on its ability to  provide low-cost waste conversion services  while
also minimizing the waste generators' liabilities. See "-- Competition."
 
SALES AND MARKETING
 
    The  Company  only recently  began to  implement  its marketing  program for
ALUMAGLASS and  will increase  its  marketing and  sales efforts  following  the
Offering  by  increasing  its  sales  and  marketing  force  and  increasing its
distribution support efforts through additional telemarketing and trade  journal
and  direct mail advertising. Particular attention will be given to direct sales
efforts with respect  to potential  large volume customers,  such as  utilities,
shipyards and large corporations with various manufacturing, maintenance and/ or
processing   operations.  In  addition,   the  Company  will   continue  to  add
distributors to increase market penetration of ALUMAGLASS. The Company will also
increase its  efforts  to market  ALUMAGLASS  for other  applications,  such  as
non-skid flooring and polishing compounds.
 
    ALUMAGLASS brand abrasives are marketed and distributed in the United States
through  the  Company's  direct  sales efforts  and  through  distributors. N.T.
Ruddock & Company, Fusco Abrasive Systems, Inc. and Omni Finishing Systems, Inc.
are initial  lead  regional distributors  of  the Company's  abrasives  and  are
large-volume  distributors of loose grain abrasives in the United States. Recent
additions to the Company's domestic distribution network include, among  others,
Porter Warner Industries Inc., Standard
 
                                       40
<PAGE>
Sand  & Silica Co., Corrosion Specialties Incorporated, Carpenter Brothers Inc.,
Grand Northern Products, Inc., MJD  Enterprises Inc., Dawson MacDonald  Company,
Metal  Preparations Co., Inc. and W.  H. Shurtleff Company. In addition, Midvale
Industries, Air Power Equipment Corp. and Ryan Equipment Co., Inc. are among the
regional sub-distributors  served  by  N.T. Ruddock  &  Company,  although  such
distributors  may also order  directly from the  Company. Other distributors are
currently testing the product. The Company has also established distributors  in
the   United  Kingdom,  Canada,  Mexico  and   Israel.  Many  of  the  Company's
distributors sell  and have  blasting equipment  in place  at numerous  customer
locations.  The  Company is  working with  these  distributors and  suppliers of
blasting equipment to have equipment users test and convert to ALUMAGLASS.
 
    The Company is  also pursuing  the introduction of  highly focused  abrasive
product  offerings  in certain  market segments,  such  as auto  refinishing and
non-skid flooring  additives.  Marketing  of  such  potential  products  may  be
conducted  directly by the Company or  through retail channels and could include
private branded products. The Company may also seek to sell ALUMAGLASS to  micro
abrasives  manufacturers who  would grind ALUMAGLASS  into micro  grit sizes for
sale  as  a  micro  abrasive   for  specialty  manufacturing  applications   and
applications  such  as  cleaning  intricate  medical  or  dental  equipment  and
polishing compounds.
 
    The Company is a party to  a Purchase, Supply and Distributorship  Agreement
(the  "VANGKOE Agreement"), entered into in March  1996 and amended in May 1996,
with VANGKOE, as assignee of Cytech Laboratories, Inc., relating to the sale  of
ALUMAGLASS  and  certain waste  materials processed  in the  Company's abrasives
finishing area for use as aggregates and additives for products such as swimming
pool plasters, tiles  and other  construction materials.  The VANGKOE  Agreement
contains  a guaranteed minimum purchase commitment  of approximately 350 tons of
ALUMAGLASS per  month over  a twelve-month  period commencing  October 1996.  At
VANKGKOE's  option,  VANGKOE  may  satisfy its  minimum  purchase  commitment by
substituting one-third of such commitment  with crushed CRT glass (resulting  in
the  sale of approximately 234 tons of  ALUMAGLASS per month). If the guaranteed
minimum purchase commitment is purchased, the Company will receive approximately
$1,560,000 in  revenue  (or  approximately  $1,240,000  if  VANGKOE  substitutes
crushed  CRT glass for one-third of  such commitment). In consideration for such
minimum purchase  commitment,  the Company  has  agreed not  to  knowingly  sell
ALUMAGLASS  to other customers for use as  an ingredient in pool plasters during
the term of the VANGKOE Agreement. VANGKOE is a newly-formed entity with nominal
assets and  no experience  in marketing  and distributing  materials similar  to
those  required  to  be  purchased  by  VANGKOE  under  the  VANKGKOE Agreement.
Accordingly, there  can be  no  assurance that  VANGKOE  will meet  its  minimum
purchase  commitments under  the VANKGKOE Agreement  or that  VANKGKOE will ever
satisfy any of its obligations under  the VANGKOE Agreement. In such event,  the
Company's  ability to  enforce its  rights under  the VANGKOE  Agreement will be
limited.
 
    The VANGKOE Agreement  also provides  the Company  with a  60-day option  to
enter  into a joint venture  with VANGKOE relating to  technology to apply color
coating to materials to be purchased by VANGKOE under the VANGKOE Agreement.  If
the  Company  determines to  proceed with  the joint  venture, the  parties will
create a new company ("NEWCO")  to apply at cost  certain color coatings to  the
material  purchased from  the Company.  VANGKOE will  grant NEWCO  an exclusive,
perpetual, royalty-free license of its technology related to such color  coating
process.  The Company  has agreed  to invest  one-half of  the cost  to fund the
purchase of coating equipment (not to exceed $125,000) and VANGKOE will obtain a
loan to finance the remaining 50% of the funds required for the purchase of such
equipment and  the Company  will  guarantee such  VANGKOE  loan (not  to  exceed
$125,000).  The VANGKOE  Agreement provides that  the Company will  share 50% of
VANGKOE's profit from its sales of the finished material color coated by  NEWCO.
VANGKOE  has agreed to obtain a primary lease  for a facility to be subleased at
cost to NEWCO and to provide a  minimum of $30,000 of working capital to  NEWCO.
If  VANGKOE defaults  on its loan  and the  Company's guarantee of  such loan is
drawn upon and not repaid immediately by VANGKOE or if VANGKOE does not  perform
certain  of  its  other obligations  under  the VANGKOE  Agreement,  the coating
technology will be  assigned to NEWCO  and VANGKOE's interest  in NEWCO will  be
assigned  to the Company, which will become the sole owner of NEWCO. The VANGKOE
Agreement further commits
 
                                       41
<PAGE>
VANGKOE to license its coating technology to  the Company for use at any  future
facility  the Company may establish for a  royalty of $0.01 per pound. The color
coating technology has  been recently  developed and  products coated  utilizing
such  technology have not  been commercially sold. Accordingly,  there can be no
assurance that NEWCO will be successful in commercializing such technology, that
the Company will ever receive revenues as a result of products sold coated  with
such  technology or  that the  Company will  not lose  its entire  investment in
NEWCO.
 
    The Company's  marketing strategies  include, among  others,  telemarketing,
direct  mail  and  trade  journal  advertising,  product  sampling  programs and
customer support  programs such  as technical  assistance programs  and  testing
support.
 
    Certain  members of the Company sales and marketing force also provide sales
support for the Company's CRT glass recycling business and are actively  engaged
in  identifying additional sources of CRT  glass and sales outlets for processed
glass.
 
    The Company currently has six individuals dedicated principally to sales and
marketing and several  others who support  the sales and  marketing effort on  a
regular  basis.  The Company  has allocated  a  portion of  the proceeds  of the
Offering to expand  its sales  and marketing  staff in  the near  future and  as
market acceptance of ALUMAGLASS grows.
 
INTELLECTUAL PROPERTY
 
    The Company has been awarded two United States patents. The first patent was
issued  in December 1993 and relates  to the Company's process for manufacturing
abrasive particles  from  inorganic  waste  materials,  including  sludges  from
various  industrial processes and waste  water treatment, emission control dusts
from  high-temperature  industrial  processes,  fly  ash  from  incineration  of
industrial  and residential wastes and certain other process-specific effluents.
Examples of  such  inorganic  wastes  are spent  pot  liner  from  the  aluminum
industry, refractory wastes from smelting, melting or refining furnaces, various
types  of slags and  precipitants related to  metal recovery operations, foundry
sands, glass wastes, including  television and computer  moniter CRT glass,  and
certain  wastes from the manufacture of  ceramic products. The second patent was
issued in October 1995 and relates to the pre-melting batching process  involved
in  the manufacture  of the  Company's abrasives.  In addition,  the Company and
ASOMA have  jointly  filed  an  application  for a  U.S.  patent  on  the  X-ray
fluorescence  technology used in  the Company's CRT  glass recycling operations.
See "-- Products and Services -- CRT Glass Recycling." The Company also has  two
additional  patent applications on file. One  relates to the Company's abrasives
and one relates to the Company's planned glass bead product.
 
    The Company's  success will  depend, in  part, on  its ability  to  maintain
protection  for its products and manufacturing processes under United States and
foreign patent  laws, to  preserve  its trade  secrets  and to  operate  without
infringing  the proprietary rights  of third parties. There  can be no assurance
that any of  the Company's patent  applications will result  in issued  patents,
that any issued patents will afford adequate protection to the Company or not be
challenged, invalidated, infringed or circumvented or that any rights thereunder
will  afford competitive advantages to the Company. Furthermore, there can be no
assurance  that  others   have  not   independently  developed,   or  will   not
independently  develop, similar products and technologies or otherwise duplicate
any of the Company's products and  technologies. There can be no assurance  that
the  validity of any patent issued to  the Company would be upheld if challenged
by others in  litigation or  that the  Company's activities  would not  infringe
patents  owned by others. The Company could incur substantial costs in defending
itself in suits brought against  it, or in suits in  which the Company seeks  to
enforce  its  patent rights  against others.  Should  the Company's  products or
technologies be found to infringe patents  issued to third parties, the  Company
would  be  required to  cease the  manufacture,  use and  sale of  the Company's
products and  the Company  could  be required  to  pay substantial  damages.  In
addition,  the Company may  be required to  obtain licenses to  patents or other
proprietary rights of third parties in  connection with the development and  use
of  its  products and  technologies. No  assurance  can be  given that  any such
licenses required would be made available on terms acceptable to the Company, or
at all.
 
                                       42
<PAGE>
    The Company also relies on trade secrets and proprietary know-how, which  it
seeks  to protect,  in part, by  confidentiality agreements  with its university
research partners, employees, consultants, advisors and others. There can be  no
assurance  that such  parties will  maintain the  confidentiality of  such trade
secrets or  proprietary information,  or that  the trade  secret or  proprietary
information  of the Company will not  otherwise become known or be independently
developed by competitors in a manner  that would have a material adverse  effect
on the Company's business, financial condition and results of operations.
 
    The  Company's logo is a registered  trademark. In addition, the Company has
filed a  trademark application  for  ALUMAGLASS with  the Patent  and  Trademark
Office.  A request to  extend the time for  filing an objection  to the mark was
requested by a  third party  and granted.  Such extension  expired December  31,
1995. The Company has not been notified of the filing of a request for a further
extension of such time period.
 
COMPETITION
 
    The  Company's manufactured abrasives will compete with product offerings of
other companies,  principally aluminum  oxide, glass  beads, plastic  abrasives,
garnet, steel grit, coal slag and, with respect to certain applications, sand or
water  blasting techniques.  Many of  the companies  offering such  products are
large corporations  with  substantially  greater financial  resources  than  the
Company.  Large  international  competitors of  manufactured  metallic abrasives
include:  Exolon-ESK,  General  Abrasives  Triebacher,  Inc.,  Washington  Mills
Electro  Minerals  Corp.,  Irvin  Industries,  Inc.  and  others.  Various other
manufacturers produce mined, plastic, glass bead and mineral abrasives, as  well
as  high  speed  water jet  spray  abrasive  systems. The  Company's  ability to
effectively compete against these companies  could be adversely affected by  the
ability  of these competitors to  offer their products at  lower prices than the
Company's products  and  to  devote  greater  resources  to  the  marketing  and
promotion of their products than are available to the Company.
 
    The principal competitive factors in the abrasives market are cost of usage,
performance,  reliability of supply and  health and safety issues. Sophisticated
users tend to  evaluate the total  cost of  usage of an  abrasives product,  and
consider  factors such as (i) the per pound cost of the abrasive; (ii) the speed
of cleaning (as it relates  to labor and overhead  cost to accomplish the  job);
(iii)  energy consumption  cost to  apply the  abrasive; (iv)  special equipment
costs and equipment maintenance costs; (v) disposal costs of the spent abrasive;
and (vi) post-abrasive application costs, such as removal of embedded  abrasive.
The  Company believes that  ALUMAGLASS provides users  with superior performance
and lower total cost  of usage in many  applications. See "Business --  Products
and Services."
 
    The  Company competes for certain of its raw materials for its abrasives and
waste  conversion  services  in  the  hazardous  and  non-hazardous  waste   and
industrial  by-products treatment and disposal  markets, which are characterized
by several  large  companies and  numerous  small companies  and  publicly-owned
landfills  who charge  for the disposal  of waste.  International waste disposal
competitors include, among others, WMX Technologies, Inc. Laidlaw Waste Systems,
Inc., Browning-Ferris Industries, Inc., Mid-American Waste Systems, Inc., Allied
Waste Industries,  Inc. and  Strategic Materials,  Inc. and  a number  of  large
European-based companies. Although the Company beneficially reuses the wastes it
receives  and  may accept  qualified  wastes for  reduced  fees compared  to its
disposal competitors, any  such companies  or any other  competitor may  develop
technologies  superior to those of the  Company or offer waste disposal services
at competitive prices. In addition, to the extent that the burdens of  complying
with  environmental laws and regulations  are eased as a  result of, among other
things, political factors,  competitors may  offer the  Company's customers  and
potential  customers  alternative  and less  costly  means to  dispose  of their
wastes. The Company's  competitive advantage and  successful market  penetration
will  depend on its ability to  provide low-cost waste conversion services while
also minimizing the waste generators' liabilities.
 
    With respect to its industrial  CRT glass recycling operations, the  Company
competes  with several other companies who  accept waste CRT glass for recycling
or other purposes,  each of which  may deal  with customers of  the Company  and
satisfy  their recycling, beneficial reuse or disposal needs. In addition, under
certain conditions,  CRT  glass might  also  be disposed  of  by melting  it  to
recapture the residuals. See "-- Market Overview" and "-- Strategy."
 
                                       43
<PAGE>
ENVIRONMENTAL MATTERS
 
    The federal environmental legislation and policies that the Company believes
are  applicable to  its manufacturing  operations in  the United  States include
RCRA, the Clean Water Act, the  Clean Air Act, CERCLA, the Superfund  Amendments
and  Reauthorization Act ("SARA") and the  Pollution Prevention Act of 1990. The
Company is also subject to state air,  water and solid and hazardous waste  laws
and  regulations  that  affect  its  manufacturing  operations.  State  laws and
regulations normally must be at least  as stringent, and may be more  stringent,
than  their  federal counterparts.  These federal  and  state laws  regulate the
management and  disposal  of hazardous  and  non-hazardous wastes,  control  the
discharge  of pollutants into  the air and water,  provide for the investigation
and remediation of  contaminated land  and groundwater  resources and  encourage
pollution   prevention  programs.   Many  of   these  laws   have  international
counterparts, particularly in Europe and elsewhere in North America.
 
    RCRA provides  a  comprehensive  regulatory framework  for  the  generation,
transportation,  treatment, storage and  disposal of solid  and hazardous waste.
RCRA regulations  require  that  hazardous waste  generators,  transporters  and
operators  of hazardous  waste treatment,  storage and  disposal facilities meet
strict standards  set by  government agencies.  In certain  circumstances,  RCRA
requires  owners/operators  of  treatment, storage  and  disposal  facilities to
obtain RCRA Part B  permits from the  EPA or from  state agencies authorized  to
implement  the RCRA program. Obtaining such permits  may be a lengthy and costly
process that requires regulatory inspection and approval of, among other things,
the facility design, equipment and operating plans and procedures. In  addition,
applicants  for a RCRA permit for a treatment, storage or disposal facility must
submit detailed information regarding all past waste management practices at the
facility,  and  may  be  required  to  undertake  corrective  action  for   past
contamination.
 
    Additionally,   RCRA  regulations  establish  "land  disposal  restrictions"
("LDRs") that prohibit disposal  of specified hazardous  wastes on land  unless,
subject  to certain exemptions,  these wastes meet  or are treated  to meet Best
Demonstrated Available  Technology  ("BDAT") treatment  standards.  The  statute
imposes  civil and, under certain  circumstances, criminal liability for failure
to comply with the regulatory requirements.
 
    Under RCRA, wastes are classified as hazardous either by specific listing or
because  they   display  certain   hazardous  characteristics.   Under   current
regulations,  waste residues derived from  listed hazardous wastes are generally
considered to  be hazardous  wastes until  they are  delisted through  a  formal
rulemaking  process that  may require  a few months  to several  years. For this
reason, waste residue  generated by  the processing of  listed hazardous  wastes
will  be considered a hazardous waste,  regardless of whether this waste residue
may be environmentally benign. Subsequent management of such waste residue would
be subject  to full  RCRA  regulation, including  the prohibition  against  land
disposal without treatment in compliance with BDAT.
 
    To maximize the market acceptance of the Company's manufacturing technology,
the  Company has chosen to focus its  initial project efforts on the development
of recycling processes, materials and products which are most likely to  qualify
for  exemptions or favorable regulatory treatment. For example, the Company will
use materials that are not solid wastes  and are not subject to RCRA  permitting
requirements (for example, reclaimed characteristically hazardous by-products or
sludges).  The Company will handle secondary materials  in a way to qualify such
materials for exclusions under state  or federal RCRA regulations (for  example,
use  of materials as effective substitutes for other products in a manufacturing
process), and  the Company  will  store materials  in an  environmentally  sound
manner  (for example, within the manufacturing  building or on a concrete slab).
The  permitting  burden  on  a  facility  utilizing  its  current  manufacturing
technology  will depend  on the nature  of the waste  streams (including whether
they are classified as solid wastes  or hazardous wastes), the configuration  of
the  process  at  the particular  facility,  the  manner in  which  products are
recovered from the waste and the type of waste residuals created by the process.
 
    The New York State Department  of Environmental Conservation ("NYSDEC")  has
been  delegated authority to  administer the RCRA  program in New  York, and has
adopted regulations governing the treatment,  storage and disposal of solid  and
hazardous  wastes. NYSDEC regulations  require the Company  to obtain regulatory
exemptions  and/or  beneficial  use  determinations  for  each  hazardous  waste
material it
 
                                       44
<PAGE>
accepts  for  recycling  purposes. Without  these  regulatory  exemptions and/or
beneficial use determinations, the Company would  be required to obtain a  State
RCRA  permit to operate its  facility, and would become  subject to onerous RCRA
regulatory requirements.
 
    The Company  presently  has  obtained  both  regulatory  determinations  and
beneficial  use  determinations from  NYSDEC concluding  that the  materials and
processes that it will use and the products that it will produce at its  Dunkirk
Facility are not subject to permits under the New York State solid and hazardous
waste  laws. However, in  view of the fact-specific,  case-by-case nature of the
approval process and the varying policies of different jurisdictions, there  can
be  no guarantee  that any  or all  of the  Company's projects  will qualify for
favorable regulatory treatment in other jurisdictions. In addition, there can be
no assurance that new  materials accepted at the  Dunkirk facility will  qualify
for favorable regulatory treatment.
 
    Pursuant to RCRA and New York State law, federal and state regulations exist
governing  aboveground and  underground storage tanks.  Under these regulations,
tanks used to store various types of petroleum must be registered with the State
until they are  permanently closed. These  regulations also establish  standards
for  permanent  closure, and  impose penalties  for failure  to comply  with the
registration or closure requirements. Although the Company does not utilize  any
underground storage tanks, there are several empty tanks at the Dunkirk facility
that  were used by the former owner  of the property to store various materials,
including fuel oil for consumptive heating use on the premises, mineral oil  for
use  in formulating printing ink and  a non-hazardous wash solution for cleaning
printing presses. The  estimated cost to  clean and  close the tanks  is in  the
range  of  $28,000  to  $34,000,  based  upon  bid  proposals  from  a qualified
environmental services firm.  An investigation by  an environmental  engineering
firm  has disclosed modest soil contamination confined to the immediate vicinity
of two  tank locations.  Because of  the  amount and  confined location  of  the
contamination,  it is  not certain  that any  remediation will  be required. The
environmental engineering firm has  estimated that, if  remediation of soil  and
groundwater  is  required,  the  cost of  excavation,  removal  and  disposal of
contaminated material would not exceed $30,000. Thus, total remediation and tank
closure  costs  are  expected  to  range  from  approximately  $28,000,  if   no
remediation  is  required,  to  approximately $64,000  if  soil  and groundwater
remediation is required.
 
    The Clean Air Act empowers EPA to establish and enforce ambient air  quality
standards  and limits on  emissions of pollutants  from specific facilities. The
Clean Air Act Amendments  of 1990 impose specific  requirements upon "major"  or
"area" sources of regulated air pollutants. In certain cases, depending upon the
area   the  source   is  located,   such  sources   may  be   required  to  meet
technology-based emissions limits based  upon Best Available Control  Technology
("BACT")  for  sources  subject  to new  source  performance  standards; Maximum
Achievable Control Technology ("MACT") for  hazardous air pollutant sources  and
Reasonably  Available Control Technology ("RACT")  or Lowest Achievable Emission
Rates ("LAER") for criteria pollutant sources in non-attainment areas. New  York
State  has  also enacted  the  Air Pollution  Control  Act, and  has promulgated
regulations pursuant to that Act that regulate air contaminant sources.
 
    Under the Clean Air Act and its Amendments, and state laws and  regulations,
the  Company may be  required to obtain a  Title V operating  permit, as well as
various other  air permits  to  construct or  operate  emission sources  at  its
facility.  The Dunkirk facility has obtained, or is in the process of obtaining,
all necessary air permits.
 
    CERCLA and subsequent amendments under SARA impose continuing liability upon
generators of hazardous substances and owners and operators of facilities  where
hazardous  waste  is released  or threatened  to  be released,  as well  as upon
parties who  arrange for  the  transportation of  hazardous substances  to  such
facilities.  CERCLA effectively imposes strict, joint and several liability upon
these parties. Accordingly,  the Company could  incur liability as  an owner  or
operator  for  releases  of hazardous  substances  at its  Dunkirk  Facility, or
possibly as a hazardous waste generator.  In addition, the Company plans to  own
and  operate other  production units  and installations,  and may  be exposed to
potential liability under CERCLA for  releases of hazardous substances into  the
environment at those sites.
 
    The  NYSDEC has reviewed extensive environmental sampling data regarding the
Company's Dunkirk facility and concluded that it is unnecessary to consider  the
site  for inclusion on the list of facilities that warrant further investigation
for potential remediation.
 
                                       45
<PAGE>
    The Community  Right-to-Know  mandate  established  by  SARA  requires  full
disclosure  of certain environmental  releases to the  public and contributes to
public awareness  and  activity  regarding  corporate  environmental  management
issues.  The Company is required pursuant  to this mandate to immediately report
any release  that meets  an  established reportable  quantity threshold  and  to
report  annually the release of certain listed chemicals in excess of applicable
thresholds. The  Company could  be found  liable and  subject to  penalties  for
failure to immediately report a reportable spill or release.
 
    The  Clean  Water  Act  establishes effluent  guidelines  and  water quality
criteria to protect the nation's  waterways. Facilities that discharge  effluent
containing  regulated pollutants directly  to "waters of  the United States" are
required to obtain a National  Pollution Discharge Elimination System  ("NPDES")
permit  that regulates the amount  of pollutant that may  be discharged into the
water. Facilities that discharge into  publicly operated sewer systems, such  as
the  Dunkirk  facility, are  required to  obtain sewer  use permits.  Dunkirk is
presently discharging its effluent to a local sewer system in compliance with  a
sewer use permit.
 
    The  Pollution Prevention Act of 1990  establishes pollution prevention as a
national objective, naming it a primary  goal wherever feasible. The Act  states
that  if  pollution cannot  be  prevented, materials  should  be recycled  in an
environmentally safe manner  in lieu of  treatment or disposal.  Under the  Act,
companies  would be  encouraged to  use recycling  facilities, such  as Dunkirk,
rather than to dispose of  their sludges or byproducts  as wastes. The Act  also
requires facilities like Dunkirk to report annually the volume of certain listed
chemicals  that  are  recycled  on  site. The  Dunkirk  facility  has  filed the

    The Company is a party to litigation commenced by the Company in the Supreme
Court of New York, County of  Chautauqua, against a general contractor hired  to
construct  the improved abrasives finishing area, which is part of the Company's
current capital expansion program. The contractor commenced work in April  1995,
but was asked to stop work in November 1995 following significant cost overruns,
problems and delays in construction and disputes with the Company over the scope
of  the work  to be  performed by the  contractor. Each  of the  Company and the
contractor have filed and  served a summons with  notice. The contractor  claims
damages  of approximately  $425,000, and the  contractor has  filed a mechanic's
lien with respect to such claim. The Company has served the contractor with  its
complaint,   alleging,  among  other  things,  breach  of  contract,  fraud  and
defamation, and seeks damages  in excess of $1,000,000.  Until such time as  the
contractor  serves the Company with its answer, the precise counterclaims of the
contractor cannot be ascertained. The Company has engaged an engineering firm to
review the contractor's work  and oversee completion  of the improved  abrasives
finishing area. Approximately $350,000 of the proceeds of the Offering have been
designated for completion of the abrasives finishing area.
 
    The  Company  does not  believe  that an  adverse  outcome in  the foregoing
dispute would have a material adverse effect on the Company. The Company is  not
involved in any other material legal proceedings.
 
EMPLOYEES
 
    At  March 1,  1996, the  Company had  approximately 67  full-time employees,
including  approximately  49  in  manufacturing,  5  in  research  and   product
applications   development,  approximately   6  in   sales  and   marketing  and
approximately 7 in finance  and administration. The  Company also currently  has
one  part-time  employee.  From time  to  time, the  Company  utilizes temporary
employees. The  Company  has used  up  to 20  temporary  employees to  meet  its
requirements.  The  Company  believes that  additional  permanent  and temporary
employees can be hired on satisfactory terms.
 
    In February 1996, a majority of the employees of Dunkirk elected the  United
Steelworkers  of America to  act as their  bargaining representative pursuant to
the NLRA. Dunkirk is obligated under the NLRA to bargain with the Union in  good
faith.  The outcome  of such  bargaining cannot be  determined. There  can be no
assurance that  the election  of the  Union  or the  outcome of  the  bargaining
process  will  not result  in  higher labor  costs,  work stoppages,  strikes or
otherwise have a material  adverse effect on  the Company's business,  financial
condition or results of operations.
 
    The Company has not experienced any work stoppages and the Company considers
its relations with its employees to be satisfactory.

SCIENTIFIC ADVISORY BOARD
 
    Since the Company's inception, the Company has sought the advisory  services
of  a number of scientists, researchers and clinicians with extensive experience
in the Company's fields of interest (the "Scientific Advisors"). The Company has
established a  Scientific Advisory  Board whose  members assist  the Company  in
identifying  product development opportunities, in reviewing and evaluating with
management the progress of research  programs, and in recruiting and  evaluating
scientists and other employees.
 
    Most  of  the Scientific  Advisors are  employed  by and/or  have consulting
agreements with entities other than the  Company, some of which may conflict  or
compete  with the Company, and they are  expected to devote only a small portion
of their time to the Company. They  are not expected to actively participate  in
the  Company's activities. Certain of the institutions with which the Scientific
Advisors are affiliated may have regulations or policies which limit the ability
of such personnel to act as part-time  consultants or in other capacities for  a
commercial  enterprise or may adopt such  regulations or policies in the future.
Furthermore, it is probable that any  inventions or processes discovered by  the
Scientific  Advisors will not become the property of the Company but will remain
the property of such persons or of such persons' full-time employers.

LIMITATION OF LIABILITY
 
    The General Corporation Law  of Delaware permits  a corporation through  its
Certificate  of  Incorporation  to  eliminate  the  personal  liability  of  its
directors to the corporation or its stockholders for monetary damages for breach
of fiduciary duty with  certain exceptions. The exceptions  include a breach  of
fiduciary  duty of loyalty, acts or omissions not in good faith or which involve
intentional misconduct or a knowing  violation of law, improper declarations  of
dividends,  and  transactions  from  which  the  directors  derived  an improper
personal benefit.  The Company's  Certificate  of Incorporation  exonerates  its
directors  from  monetary  liability to  the  fullest extent  permitted  by this
statutory provision but does not  restrict the availability of non-monetary  and
other equitable relief.
 
                                       52
<PAGE>
    The  Company believes that it is the position of the Commission that insofar
as the foregoing provision may be invoked to disclaim liabilities arising  under
the  Securities Act, the provision is against  public policy as expressed in the
Securities Act and is therefore unenforceable. Such limitation of liability also
does not affect the availability of injunctive relief or recission.
 
    The Company intends to  enter into Indemnification  Agreements with each  of
its  directors and executive officers prior to the date of this Prospectus. Each
such Indemnification Agreement will provide that the Company will indemnify  the
indemnitee  against expenses,  including reasonable  attorney's fees, judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by him  in  connection with  any  civil  or criminal  action  or  administrative
proceeding arising out of the performance of his duties as an officer, director,
employee  or agent of the  Company. Indemnification is available  if the acts of

STOCK OPTION PLANS
 
    EMPLOYEE STOCK OPTION PLAN
 
    In  June  1994,  the Board  of  Directors  adopted, and  in  April  1995 the
Stockholders approved  the  Conversion  Technologies  International,  Inc.  1994
Employee  Stock Option  Plan (the  "Employee Stock  Option Plan").  The Employee
Stock Option Plan provides for the grant to consultants, officers and  employees
of both "incentive stock options" within the meaning of Section 422 of the Code,
and  stock  options  that are  non-qualified  for federal  income  tax purposes.
Effective upon the closing of the Offering, the total number of shares which may
be issued upon exercise of options granted pursuant to the Employee Stock Option
Plan will increase from 79,170 shares to 440,000 shares pursuant to an amendment
to the Employee  Stock Option  Plan adopted  by the  Board and  approved by  the
holders  of a majority of the outstanding voting capital stock of the Company in
November 1995.
 
    As of the date of  this Prospectus, the Company  has options to purchase  an
aggregate  of 73,010 shares of Common Stock outstanding under the Employee Stock
Option  Plan.  Effective  as  of  the  date  of  this  Prospectus,  pursuant  to
resolutions adopted by the Board in December 1995, all options outstanding under
the  Employee Stock Option Plan have been  repriced to have an exercise price of
$4.40 per share, representing the Board's good faith estimate of the fair  value
of  one share  of Common Stock  as of the  date of this  Prospectus after giving
effect to the Offering.
 
    The  Employee  Stock  Option  Plan  will  terminate  in  June  2004,  unless
terminated  earlier  by  the  Board  of  Directors.  The  Compensation Committee
administers the Employee Stock Option Plan and determines which of the Company's
consultants, officers and employees will receive options, the time when  options
are  granted, whether the  options are incentive  stock options or non-qualified
stock options, the terms of such options,  the exercise date of any options  and
the  number of shares subject to  options. Members of the Compensation Committee
are not  eligible to  receive  options under  the  Employee Stock  Option  Plan.
Directors  who  are also  employees are  eligible to  receive options  under the
Employee Stock Option Plan. Non-employee  directors are not eligible to  receive
options under the Employee Stock Option Plan.
 
    The  exercise price  of incentive stock  options granted  under the Employee
Stock Option Plan  may not be  less than 100%  of the fair  market value of  the
Common  Stock at the time of grant, and the term of any option may not exceed 10
years. With respect to any employee who owns stock representing more than 10% of
the voting power of the outstanding  capital stock of the Company, the  exercise
price of any incentive stock option may not be less than 110% of the fair market
value  of such shares at the time of grant,  and the term of such option may not
exceed five  years.  The exercise  price  of  a non-qualified  stock  option  is
determined  by the  Compensation Committee  on the  date the  option is granted.
However, in the case of options granted  after the date of this Prospectus,  the
exercise  price of a non-qualified stock option may not be less than 100% of the
fair market value of the  Common Stock at the time  of grant. Subsequent to  the
date  of the grant  of a non-qualified stock  option, the Compensation Committee
may, at its discretion  and with the  consent of the  optionee, establish a  new
price for such non-qualified stock option.
 
                                       54
<PAGE>
    Options  granted under  the Employee  Stock Option  Plan are nontransferable
and, with certain  exceptions in  the event  of the  death or  disability of  an
optionee,  may be exercised by  the optionee only during the  term of his or her
employment. Options granted under the Employee Stock Option Plan typically  vest
over a three-year period and expire after seven years.
 
    STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS
 
    In  June  1994,  the Board  of  Directors  adopted, and  in  April  1995 the
Stockholders approved the Conversion Technologies International, Inc. 1994 Stock
Option Plan for Non-Employee Directors (the "Stock Option Plan for  Non-Employee
Directors").  The purpose of the Stock Option Plan for Non-Employee Directors is
to attract and retain the services of experienced and knowledgeable  independent
directors of the Company for the benefit of the Company and its stockholders and
to  provide additional incentive for such directors  to continue to work for the
best interests of the Company and its stockholders through continuing  ownership
of Common Stock. Effective upon the closing of the Offering, the total number of
shares  which may  be issued  upon exercise of  options granted  pursuant to the
Stock Option Plan for Non-Employee Directors will increase from 24,360 shares to
70,400 shares pursuant to an amendment to the Stock Option Plan for Non-Employee
Directors adopted by the Board and approved by the holders of a majority of  the
outstanding voting capital stock of the Company in November 1995.
 
    As  of the date of  this Prospectus, the Company  has options to purchase an
aggregate of 7,483  shares of Common  Stock outstanding under  the Stock  Option
Plan  for Non-Employee Directors.  Effective as of the  date of this Prospectus,
pursuant to  resolution adopted  by  the Board  in  December 1995,  all  options
outstanding  under the  Stock Option Plan  for Non-Employee  Directors have been
repriced to have an exercise price of $4.40, representing the Board's good faith
estimate of the fair value of one share  of Common Stock as of the date of  this
Prospectus after giving effect to the Offering.
 
    The  Stock Option  Plan for  Non-Employee Directors  is administered  by the
Board of  Directors.  Subject  to  the  terms  of  the  Stock  Option  Plan  for
Non-Employee  Directors,  the  Board  of Directors  has  the  sole  authority to
determine questions arising under, and to adopt rules for the administration of,
the Stock Option Plan for  Non-Employee Directors. The Directors will  determine
which  of the  Company's non-employee directors  will receive  options, the time
when options are granted, the terms of such options and the exercise date of any
options. The Stock Option Plan for  Non-Employee Directors may be terminated  at
any  time by  the Board of  Directors, but  such action will  not affect options
previously granted pursuant thereto.
 
    Directors of the  Company who  are not,  and who  have not  been during  the
immediately   preceding  12-month  period,  employees  of  the  Company  or  any
subsidiary  of  the  Company  (a  "Non-Employee  Director")  are   automatically
participants in the Stock Option Plan for Non-Employee Directors.
 
    Prior  to  the Effective  Date  of the  Stock  Option Plan  for Non-Employee
Directors (as defined below), the Board of Directors shall determine the  number
of  shares subject to  each option. After the  Effective Date, each Non-Employee
Director who is in office on July 1 of any year (commencing with the first  July
1  occurring after the Effective Date of  the Stock Option Plan for Non-Employee
Directors) shall, as of  July 1, automatically be  granted an option to  acquire
121  shares of Common  Stock. The Effective Date  will be the  date on which the
Offering is consummated. The price of shares that may be purchased upon exercise
of an option is the fair market value of the Common Stock on the date of  grant,
as  evidenced by the average of the high and low sales prices of Common Stock on
such date  as reported  on the  Nasdaq Stock  Market or  the closing  price,  if
applicable,  or the average of the last bid  and asked prices on the date of the
grant as reported  on the Nasdaq  Stock Market.  If there is  no public  trading
market  for such shares,  the fair value  of such shares  shall be determined in
good faith by the Board  of Directors of the Company.  The term of each  option,
except as discussed below, is for a period not exceeding ten years from the date
of  grant.  Options may  not be  assigned or  transferred except  by will  or by
operation of the laws of descent and distribution.
 
    In the event of a  Change in Control of the  Company (as defined below),  an
option  granted to  a Non-Employee  Director will  become fully  exercisable if,
within one year of such Change in Control, such Non-Employee Director ceases for
any reason to be a member of the Board of Directors. A Change in Control will be
deemed to have occurred if (a) there is consummated any consolidation or  merger
of  the  Company  in  which  the Company  is  not  the  continuing  or surviving
corporation   or   any   sale   of   all,   or   substantially   all,   of   the
 
                                       55
<PAGE>
assets of the Company; (b) the stockholders approve any plan or proposal for the
liquidation  or dissolution of the Company; (c) any person or entity becomes the
beneficial owner of 50% or more of  the outstanding Common Stock; or (d)  during
any  period of two consecutive  years, individuals who at  the beginning of such
period constitute  the  entire  Board  of Directors  cease  for  any  reason  to
constitute  a  majority  thereof  unless the  election,  or  the  nomination for
election by the Company's stockholders, of  each new director was approved by  a
vote  of at  least two-thirds  of the  directors then  still in  office who were
directors at the beginning of the period. Any exercise of an option permitted in
the event of a Change  of Control must be made  within 180 days of the  relevant
Non-Employee Director's termination as a director of the Company.

SERIES A PRIVATE PLACEMENT
 
    Between August  1994 and  May 1995,  Paramount Capital,  Inc.  ("Paramount")
acted  as  placement  agent in  connection  with  the private  placement  of the
Company's Series  A  Preferred  Stock  (the  "Series  A  Placement").  Paramount

restated as of the  date of this  Prospectus to be  warrants to purchase  97,185
shares  of Common Stock at an exercise  price of $4.84 per share. Until November
1997, Paramount will  be entitled to  receive a  fee of 13%  on any  investments
received  by the Company from investors or corporate partners (excluding project

with  warrants to purchase that number of  shares of Common Stock of the Company
as is equal  to 5%  of the  amount invested divided  by the  Common Stock  share

by either party upon 30-days' prior written notice.

BRIDGE LOANS
 
    In April 1994,  the Company  consummated the 1994  Financing whereby  Harvey
Goldman,  the Chairman,  President and Chief  Executive Officer  of the Company,
Jeffrey Wolf, a  former Chairman,  director and  a stockholder  of the  Company,

and Chief Executive Officer, purchased $600,000 in an aggregate principal amount
of  7% Convertible  Bridge Notes,  due October  31, 1995.  These notes converted
(together with  interest) into  45,304 shares  of Common  Stock of  the  Company
simultaneously  with  the closing  of the  Merger.  In addition,  each purchaser
received a warrant to purchase shares  of Common Stock at an aggregate  exercise
price equal to the principal amount of the note purchased by such purchaser. The
warrants  had an initial per share exercise price equal to $13.55. Such warrants
have been amended and restated, effective as of the date of this Prospectus,  to
become  exercisable for 125,786 shares  of Common Stock at  an exercise price of
$4.77 per share. In connection with the 1994 Financing, Palmetto has a right  of

    In September, October and November  1995, the Company borrowed an  aggregate
of  $650,000 from  stockholders of the  Company or their  affiliates for working
capital. Of such amount, an  aggregate of $250,000 was  provided by TFP III  and
TFVP  V, $200,000  was provided  by Palmetto  and an  aggregate of  $200,000 was
provided by the Aries Domestic Fund L.P. and the Aries Trust, two funds in which
Lindsay Rosenwald is the sole stockholder  and President of the general  partner
and  investment manager,  respectively. The principal  amount of  such loans was
exchanged at the closing of the  Bridge Financing for $650,000 principal  amount
of  Bridge Notes and Bridge Warrants to  purchase 325,000 shares of Common Stock
(which Bridge Warrants  will be exchanged  automatically on the  closing of  the
Offering for the Selling Securityholder Warrants).
 
    In December 1995, the Company completed the Bridge Financing of an aggregate
of  $2,225,000 principal amount of Bridge Notes and 1,112,500 Bridge Warrants in
which it received net  proceeds of approximately  $1,849,750 (after expenses  of
such offering). The Bridge Notes are payable, together with interest at the rate
of  10%  per annum,  on the  earlier of  December  1996 and  the closing  of the
Offering. See  "Use  of Proceeds."  The  Bridge Warrants  entitled  the  holders
thereof  to purchase one share  of Common Stock commencing  in December 1996 but
will be exchanged automatically on the  closing of the Offering for the  Selling
Securityholder Warrants, each of which will be identical to the Class A Warrants
included  in the Units offered hereby.  The Selling Securityholder Warrants have
been  registered  for  resale  in  the  Registration  Statement  of  which  this
Prospectus forms a part, subject to the contractual restriction that the Selling
Securityholders  have agreed not to exercise the Selling Securityholder Warrants
for a period of one year  from the closing of the  Offering and not to sell  the
Securityholder  Warrants except after specified periods commencing 90 days after
the closing date of the Offering. Certain stockholders of the Company  purchased
an  aggregate of  $650,000 principal amount  of Bridge Notes  and 325,000 Bridge
Warrants by cancellation of promissory notes previously issued by the Company to
them in an equivalent principal amount. See "Concurrent Offering."
 
    In March 1996,  the Company borrowed  an aggregate of  $200,000 pursuant  to
primissory  notes bearing interest at the rate  of 10% per annum, payable on the
earlier of the closing of the Offering  and September 1996. Of such amount,  Dr.
Rosenwald provided $150,000, Scott Katzmann and Peter Kash each provided $18,750

    740,559  shares  of Common  Stock  have been  deposited  into escrow  by the
holders thereof, including Harvey Goldman  (100,725), Scott A. Katzmann  (12,179
shares),  The Long  Term Equity Holdings  Trust (138,218  shares) and VentureTek
L.P. (138,218 shares). Mr.  Goldman and Perry A.  Pappas, executive officers  of
the  Company, have deposited  into escrow options to  purchase 50,000 and 21,923
shares of  Common Stock,  respectively, held  by them  on the  date hereof.  The
Escrow  Securities are not assignable or  transferable. The holders thereof have
the power  to vote  the Escrow  Shares while  such Shares  are held  in  escrow.
Holders  of any  options in  escrow may  exercise their  options prior  to their
release from escrow; however,  the shares issuable upon  any such exercise  will
continue  to be held in  escrow as Escrow Shares.  The Escrow Securities will be
released from escrow, on a pro rata basis,  if, and only if, one or more of  the
following conditions is/are met:
 
        (a)  the  Company's net  income before  provision  for income  taxes and
    exclusive of any extraordinary earnings  or charges which would result  from
    the  release  of the  Escrow  Securities (all  as  audited by  the Company's
    independent public accountants) (the "Minimum Pretax Income") amounts to  at
    least $4.7 million for the fiscal year ending June 30, 1998;
 
        (b)  the Minimum Pretax Income amounts to  at least $7.0 million for the
    fiscal year ending June 30, 1999;
 
        (c) the Minimum Pretax Income amounts  to at least $9.3 million for  the
    fiscal year ending June 30, 2000;
 
        (d)  the  Closing  Price  (as defined)  of  the  Company's  Common Stock
    averages in excess  of $11.25  per share  for 60  consecutive business  days
    during the 18-month period commencing on the date of this Prospectus;
 
        (e)  the Closing Price of the  Company's Common Stock averages in excess
    of $15.00 per  share for 60  consecutive business days  during the  18-month
    period commencing 18 months from the date of this Prospectus; or
 
        (f)  during the periods  specified in (d)  or (e) above,  the Company is
    acquired by or  merged into  another entity in  a transaction  in which  the
    value  of the  per share consideration  received by the  stockholders of the
    Company on the date of such transaction or at any time during the applicable
    period set  forth  in  (d)  or (e),  respectively,  equals  or  exceeds  the
    applicable levels set forth in (d) or (e), respectively.
 
    The  Minimum Pretax Income  amounts set forth above  shall (i) be calculated
exclusive of any extraordinary earnings or any charges to income resulting  from
release  of the Escrow  Securities, and (ii)  be increased proportionately, with
certain  limitations,  in  the  event  additional  shares  of  Common  Stock  or
securities  convertible into, exchangeable for  or exercisable into Common Stock
are issued after completion of the Offering. The Closing Price amounts set forth
above are subject to adjustment in the event of any stock splits, reverse  stock
splits or other similar events.
 
    Any  money, securities,  rights or  property distributed  in respect  of the
Escrow Securities, including any property  distributed as dividends or  pursuant
to  any stock split, merger, recapitalization,  dissolution, or total or partial
liquidation of the Company, shall be held in escrow until release of the  Escrow
Securities.  If none  of the applicable  Minimum Pretax Income  or Closing Price
levels set forth above have been met by October 15, 2000, the Escrow Securities,
as well as any dividends or other distributions made with respect thereto,  will
be  cancelled and contributed to the capital of the Company. The Company expects
that the release of any Escrow Securities to officers, directors, employees  and
consultants  of the Company  will be deemed  compensatory and, accordingly, will
result in a  charge to reportable  earnings, which would  equal the fair  market
value of such shares on the date of release. Such charge could increase the loss
or reduce or eliminate the Company's net income for financial reporting purposes
for  the period(s) during  which such shares  are, or become  probable of being,
released from escrow. Although the amount of compensation expense recognized  by
the  Company will  not affect the  Company's total stockholders'  equity, it may
have a negative effect on the market price of the Company's securities.
 
    The Minimum Pretax  Income and  Closing Price  levels set  forth above  were
determined by negotiation between the Company and the Underwriter and should not
be  construed to  imply or  predict any  future earnings  by the  Company or any
increase in the market price of its securites.

the  closing of the Offering; provided, however, that purchasers of such Selling
Securityholder Warrants are not subject to such restrictions on exercise.  After
the  one  year  period  following  the  closing  of  the  Offering,  the Selling
Securityholders may exercise and sell the Common Stock issuable upon exercise of
the Selling Securityholder Warrants without restriction if a current  prospectus
relating  to such Common Stock is in effect and the securities are qualified for
sale. The Company will  not receive any  proceeds from the  sale of the  Selling
Securityholder  Warrants. Sales  of Selling Securityholder  Warrants issued upon
conversion of the  Bridge Warrants  or the  securities underlying  such Class  A
Warrants or even the potential of such sales could have an adverse effect on the
market prices of the Common Stock and the Warrants.
 
    The  sale of the  securities by the Selling  Securityholders may be effected
from time to time  in transactions (which may  include block transactions by  or
for  the account of the Selling  Securityholders) in the over-the-counter market
or in  negotiated  transactions,  a  combination of  such  methods  of  sale  or
otherwise.  Sales may be  made at fixed  prices which may  be changed, at market
prices or in negotiated transactions, a  combination of such methods of sale  or
otherwise.
 
    There  are no material relationships  between any Selling Securityholder and
the  Company,  except  that  TFP  III,  TFVP  V  and  Palmetto  Partners,  Ltd.,
stockholders of the Company, are Selling Securityholders. In addition, the Aries
Domestic  Fund L.P. and the  Aries Trust, two investment  funds in which Lindsay
Rosenwald, the  President and  Chairman of  Paramount, the  Company's  placement
agent  for the Series A Placement, is  the sole stockholder and President of the
general   partner   and   investment   manager,   respectively,   are    Selling
Securityholders.  See "Certain Transactions."  The Company has  been informed by
the Underwriter that  there are no  agreements between the  Underwriter and  any
Selling  Securityholder regarding the distribution of the Selling Securityholder
Warrants or the underlying securities.
 
    Selling Securityholders  may  effect  such  transactions  by  selling  their
securities  directly to purchasers, through  broker-dealers acting as agents for
the Selling  Securityholders or  to broker-dealers  who may  purchase shares  as
principals  and  thereafter  sell  the  securities  from  time  to  time  in the
over-the-counter  market,  in   negotiated  transactions   or  otherwise.   Such
broker-dealers,  if  any, may  receive compensation  in  the form  of discounts,
concessions  or  commissions  from   the  Selling  Securityholders  and/or   the
purchasers  from whom such broker-dealer  may act as agents  or to whom they may
sell  as  principals  or  otherwise  (which  compensation  as  to  a  particular
broker-dealer may exceed customary commissions).
 
    Under  applicable rules and  regulations under the  Exchange Act, any person
engaged in the  distribution of  the Selling Securityholder's  Warrants may  not
simultaneously engage in market-making activities with respect to any securities
of  the Company  during the  applicable "cooling-off"  period (at  least two and
possibly nine business  days) prior  to the commencement  of such  distribution.
Accordingly,  in  the event  the  Underwriter or  Blair &  Co.  is engaged  in a
distribution of the Selling Securityholder Warrants, neither of such firms  will
be  able to  make a  market in  the Company's  securities during  the applicable
restrictive period.
 
                                       64
<PAGE>
However,  neither the Underwriter nor Blair & Co. has agreed to nor is either of
them obligated to act as broker-dealer in the sale of the Selling Securityholder
Warrants and the Selling Securityholders may be required, and in the event Blair
& Co.  is a  market-maker, will  likely  be required,  to sell  such  securities
through another broker-dealer. In addition, each Selling Securityholder desiring
to  sell Warrants will be  subject to the applicable  provisions of the Exchange
Act and the rules and regulations thereunder, including without limitation Rules
10b-6 and 10b-7,  which provisions  may limit the  timing of  the purchases  and
sales of shares of the Company's securities by such Selling Securityholder.
 
    The Selling Securityholders and broker-dealers, if any, acting in connection
with  such sales  might be  deemed to  be "underwriters"  within the  meaning of
Section 2(11) of the Securities Act and any commission received by them and  any
profit  on  the resale  of the  securities  might be  deemed to  be underwriting
discount and commissions under the Securities Act.
 
                           DESCRIPTION OF SECURITIES
 
    The following description of the Company's securities does not purport to be
complete and is subject in  all respects to applicable  Delaware law and to  the
provisions  of the Company's Amended  and Restated Certificate of Incorporation,
as  amended,  and  By-laws,  the  Warrant  Agreement  among  the  Company,   the
Underwriter  and  American Stock  Transfer &  Trust  Company, as  warrant agent,
pursuant to which  the Warrants will  be issued and  the Underwriting  Agreement
between  the Company and the Underwriter, copies of all of which have been filed
with the Commission  as Exhibits  to the  Registration Statement  of which  this
Prospectus is a part.
 
GENERAL
 
    The  Company's  authorized capital  stock consists  of 25,000,000  shares of
Common Stock, $.00025 par value, and 15,000,000 shares of preferred stock, $.001
par value  ("Preferred Stock"),  of  which 2,958,000  shares are  designated  as
Series  A  Preferred  Stock  and  12,042,000 are  "blank  check"  or  subject to
designation by the  Board. All  of the Company's  2,958,000 shares  of Series  A
Preferred  Stock outstanding will convert into  1,023,054 shares of Common Stock
at the closing of the Offering and will not be subject to reissuance.
 
COMMON STOCK
 
    The Company currently has outstanding  902,096 shares of Common Stock,  held
of  record by approximately 60 holders. An additional 1,023,054 shares of Common
Stock will be  issued upon conversion  of the  Series A Preferred  Stock at  the
closing of the Offering. Holders of Common Stock have the right to cast one vote
for  each share held of record on all  matters submitted to a vote of holders of
Common Stock, including the election of directors. There is no right to cumulate
votes for the  election of  directors. Stockholders  holding a  majority of  the
voting  power of the capital stock issued  and outstanding and entitled to vote,
represented in person or by proxy, are  necessary to constitute a quorum at  any
meeting of the Company's stockholders, and the vote by the holders of a majority
of  such outstanding shares is required  to effect certain fundamental corporate
changes such  as liquidation,  merger  or amendment  of the  Company's  Restated
Certificate of Incorporation.
 
    Holders  of Common Stock are entitled to receive dividends pro rata based on
the number of shares held, when, as  and if declared by the Board of  Directors,
from  funds legally available therefor, subject to  the rights of holders of any
outstanding Preferred Stock.  In the  event of the  liquidation, dissolution  or
winding  up of the affairs  of the Company, all assets  and funds of the Company
remaining after the payment of all  debts and other liabilities, subject to  the
rights  of the holders of any outstanding Preferred Stock, shall be distributed,
pro rata, among the holders of the Common Stock. Holders of Common Stock are not
entitled to preemptive or  subscription or conversion rights,  and there are  no
redemption  or  sinking  fund provisions  applicable  to the  Common  Stock. All
outstanding shares of Common Stock are,  and the shares of Common Stock  offered
hereby will be when issued, fully paid and non-assessable.
 
REDEEMABLE WARRANTS
 
    CLASS  A WARRANTS.  Each  Class A Warrant entitles  the registered holder to
purchase one share of Common Stock and one Class B Warrant at an exercise  price
of $5.85 at any time until 5:00 P.M., New York
 
                                       65
<PAGE>
City  time,  on  May  15,  2001.  Commencing one  year  from  the  date  of this
Prospectus, the  Class A  Warrants are  redeemable by  the Company  on 30  days'
written notice at a redemption price of $.05 per Class A Warrant if the "closing
price"  of the Company's Common Stock for any 30 consecutive trading days ending
within 15 days  of the  notice of  redemption averages  in excess  of $8.20  per
share.  "Closing  price" shall  mean  the closing  bid  price if  listed  in the
over-the-counter market on  Nasdaq or  otherwise or  the closing  sale price  if
listed  on the  Nasdaq National  Market or  a national  securities exchange. All
Class A Warrants must be redeemed if any are redeemed.
 
    CLASS B WARRANTS.   Each Class B Warrant  entitles the registered holder  to
purchase  one share of  Common Stock at an  exercise price of  $7.80 at any time
after issuance until 5:00 P.M. New York  City time, on May 15, 2001.  Commencing
one  year from the date of this  Prospectus, the Class B Warrants are redeemable
by the Company  on 30 days'  written notice at  a redemption price  of $.05  per
Class B Warrant, if the closing price (as defined above) of the Company's Common
Stock for any 30 consecutive trading days ending within 15 days of the notice of
redemption  averages in excess of $10.95 per share. All Class B Warrants must be
redeemed if any are redeemed.
 
    GENERAL.  The Class A Warrants and Class B Warrants will be issued  pursuant
to  a  warrant  agreement  (the  "Warrant  Agreement")  among  the  Company, the
Underwriter and American Stock Transfer & Trust Company, New York, New York,  as
warrant   agent  (the  "Warrant  Agent"),  and  will  be  evidenced  by  warrant
certificates in  registered form.  The Warrants  provide for  adjustment of  the
exercise  price and for a change in  the number of shares issuable upon exercise
to protect holders  against dilution  in the event  of a  stock dividend,  stock
split,  combination or reclassification of the  Common Stock or upon issuance of
shares of Common  Stock at  prices lower  than the  market price  of the  Common
Stock, with certain exceptions.
 
    The  exercise prices of the Warrants  were determined by negotiation between
the Company and the Underwriter and should not be construed to be predictive  of
or to imply that any price increases in the Company's securities will occur.
 
    The  Company  has  reserved  from  its  authorized  but  unissued  shares  a
sufficient number of shares  of Common Stock for  issuance upon the exercise  of
the  Class A Warrants and the Class B  Warrants. A Warrant may be exercised upon
surrender of the  Warrant certificate  on or prior  to its  expiration date  (or
earlier  redemption date) at the offices of  the Warrant Agent, with the form of
"Election to Purchase" on the reverse side of the Warrant certificate  completed
and executed as indicated, accompanied by payment of the full exercise price (by
certified  or bank check payable to the order  of the Company) for the number of
shares with respect to which the  Warrant is being exercised. See "Risk  Factors
- --  Current  Prospectus  Required  to  Exercise  Warrants."  Shares  issued upon
exercise of Warrants and  payment in accordance with  the terms of the  Warrants
will  be validly  issued, fully  paid and  non-assessable. For  the life  of the
Warrants, the holders thereof have the opportunity to profit from a rise in  the
market  value of the Common Stock, with  a resulting dilution in the interest of
all other stockholders. So  long as the Warrants  are outstanding, the terms  on
which the Company could obtain additional capital may be adversely affected. The
holders  of the Warrants might  be expected to exercise them  at a time when the
Company would, in all likelihood, be able to obtain any needed capital by a  new
offering  of securities on terms  more favorable than those  provided for by the
Warrants.
 
    The Warrants do not confer upon the Warrantholder any voting or other rights
of a stockholder of the Company. Upon notice to the Warrantholders, the  Company
has  the right to reduce the exercise price or extend the expiration date of the
Warrants.
 
UNDERWRITER'S OPTIONS
 
    The Company has agreed  to grant to the  Underwriter or its designees,  upon
the closing of the Offering, the Underwriter's Options to purchase up to 306,700
shares  of Common Stock and/or  306,700 Class A Warrants  and/or 306,700 Class B
Warrants. These securities will  be identical to  the securities offered  hereby
except that the Class A Warrants and the Class B Warrants issuable upon exercise
of  the Underwriter's Options will  not be subject to  redemption by the Company
until the Underwriter's Options have been exercised and the underlying  warrants
are    outstanding.   The   Underwriter's   Options   cannot   be   transferred,
 
                                       66
<PAGE>
sold, assigned  or hypothecated  for two  years, except  to any  officer of  the
Underwriter or members of the selling group or their officers. The Underwriter's
Options  are exercisable during the three-year  period commencing two years from
the date of this Prospectus  at an exercise price of  $6.16 per share of  Common
Stock,  $.07 per  Class A  Warrant and  $.07 per  Class B  Warrant (140%  of the
initial public  offering price  of  such securities)  subject to  adjustment  in
certain  events to  protect against dilution.  The holders  of the Underwriter's
Options  have   certain   demand   and  piggyback   registration   rights.   See
"Underwriting."
 
OTHER WARRANTS
 
    As  of the closing of the Offering, exclusive of the Warrants offered hereby
and  the  Selling  Securityholder  Warrants  and  after  giving  effect  to  the
conversion  of the Series A Preferred Stock  into Common Stock, the Company will
have outstanding warrants to purchase an  aggregate of 319,204 shares of  Common
Stock,  issued to stockholders of and consultants to the Company having exercise
prices ranging from $4.40 to $5.28 per share. See "Certain Transactions."
 
PREFERRED STOCK
 
    After completion of the Offering, the Company will be authorized to issue up
to 12,042,000 shares of  "blank-check" Preferred Stock.  The Board of  Directors
will  have the authority to issue this Preferred Stock in one or more series and
to fix the number of shares  and the relative rights, conversion rights,  voting
rights   and  terms  of  redemption  (including  sinking  fund  provisions)  and
liquidation preferences, without further vote or action by the stockholders.  If
shares  of Preferred  Stock with voting  rights are issued,  such issuance could
affect the  voting  rights of  the  holders of  the  Company's Common  Stock  by
increasing  the number  of outstanding shares  having voting rights,  and by the
creation of class or series voting rights. If the Board of Directors  authorizes
the  issuance of shares of Preferred Stock with conversion rights, the number of
shares of Common Stock outstanding could  potentially be increased by up to  the
authorized   amount.   Issuance  of   Preferred   Stock  could,   under  certain
circumstances, have the effect of delaying or preventing a change in control  of
the  Company and  may adversely  affect the rights  of holders  of Common Stock.
Also, Preferred Stock could  have preferences over the  Common Stock (and  other
series  of preferred stock) with respect to dividend and liquidation rights. The
Company currently has no plans to issue any Preferred Stock.
 
TRANSFER AGENT
 
    American Stock  Transfer &  Trust Company,  New York,  New York,  serves  as
Transfer  Agent  for  the shares  of  Common  Stock and  Warrant  Agent  for the
Warrants.
 
BUSINESS COMBINATION PROVISIONS
 
    The  Company  is  subject  to   a  Delaware  statute  regulating   "business
combinations,"  defined  to  include  a  broad  range  of  transactions, between
Delaware corporations and "interested stockholders," defined as persons who have
acquired at least 15% of a corporation's stock. Under the law, a corporation may
not engage in  any business combination  with any interested  stockholder for  a
period of three years from the date such person became an interested stockholder
unless  certain conditions are  satisfied. The Company has  not sought to "elect
out" of  the  statute and,  therefore,  upon closing  of  the Offering  and  the
registration  of  its  shares  of  Common  Stock  under  the  Exchange  Act, the
restrictions imposed by such statute will apply to the Company.
 
REGISTRATION RIGHTS
 
    The Company has granted certain demand and piggy-back registration rights to
holders of 1,023,054  shares of  Common Stock  issuable upon  conversion of  the
Series A Preferred Stock purchased in the Series A Placement.
 
    The Company has granted certain demand and piggy-back registration rights to
holders  of 45,304  shares of  Common Stock issued  in connection  with the 1994
Financing.
 
    The Company has granted certain piggy-back registration rights to holders of
257,808 shares of Common Stock issued in connection with the Merger.
 
                                       67
<PAGE>
    The Company has granted certain demand and piggy-back registration rights to
the holders  of warrants  to purchase  293,365 shares  of Common  Stock and  the
holders of the Common Stock issued or issuable upon exercise thereof.
 
    All of the above described registration rights have been waived for a period
of 13 months following completion of the Offering.
 
    The  holders of  the Underwriter's Options  will have  demand and piggy-back
registration rights relating to such options and the underlying securities.  See
"Underwriting."
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have outstanding 4,992,150
shares  of Common Stock. Of  these shares, the 3,067,000  shares of Common Stock
offered hereby  will  be  freely transferable  without  restriction  or  further
registration  under the  Securities Act, unless  purchased by  affiliates of the
Company as that  term is defined  in Rule  144 under the  Securities Act  ("Rule
144")   described  below.  The  1,925,150   shares  of  Common  Stock  currently
outstanding (after giving effect to conversion of the Series A Preferred  Stock)
are  "restricted securities" or  within the meaning  of Rule 144  and may not be
sold publicly unless they  are registered under the  Securities Act or are  sold
pursuant to Rule 144 or another exemption from registration. Such shares will be
eligible for sale in the public market pursuant to Rule 144 commencing in August
1996.  However, the holders of  approximately 1,891,440 shares (or approximately
98% of the Common Stock outstanding  prior to the Offering (after giving  effect
to  the conversion of the Series A  Preferred Stock into Common Stock)), and the
holders of all of  the Company's options and  warrants outstanding prior to  the
Offering, have agreed not to publicly sell or otherwise dispose of any shares of
Common  Stock without the Underwriter's prior written consent for a period of 13
months after the date of this Prospectus. See "Underwriting."
 
    In  general,  under  Rule  144  a  person  (or  persons  whose  shares   are
aggregated),  including  persons who  may be  deemed to  be "affiliates"  of the
Company as that term is  defined under the Securities  Act, is entitled to  sell
within  any three-month period a number  of restricted shares beneficially owned
for at least two years that  does not exceed the greater  of (i) 1% of the  then
outstanding shares of Common Stock or (ii) an amount equal to the average weekly
trading volume in the Common Stock during the four calendar weeks preceding such
sale.  Sales under Rule 144  are also subject to  certain requirements as to the
manner of sale, notice and the availability of current public information  about
the  Company.  However,  a  person  who  is  not  deemed  an  affiliate  and has
beneficially owned such shares for at least three years is entitled to sell such
shares without regard to the volume or other resale requirements.
 
    Under Rule  701 of  the Securities  Act, persons  who purchase  shares  upon
exercise of options granted prior to the date of this Prospectus are entitled to
sell  such shares after  the 90th day  following the date  of this Prospectus in
reliance on  Rule  144,  without  having  to  comply  with  the  holding  period
requirements  of Rule 144 and, in the  case of non-affiliates, without having to
comply with the public  information, volume limitation  or notice provisions  of
Rule  144. Affiliates are subject to all Rule 144 restrictions after this 90-day
period, but without a holding  period. If all the  requirements of Rule 701  are
met,  an aggregate of 24,046 shares  subject to outstanding vested stock options
may be sold pursuant to such rule at  the end of this 90-day period, subject  to
an  agreement by  all option  holders not  to sell  or otherwise  dispose of any
shares of  Common Stock  for  a period  of  13 months  after  the date  of  this
Prospectus without the Underwriter's prior written consent.
 
    Pursuant  to  registration  rights  acquired in  the  Bridge  Financing, the
Company has, concurrently with the Offering, registered for resale on behalf  of
the Selling Securityholders, the Selling Securityholder
 
                                       68

Securities   subject   to   the  contractual   restriction   that   the  Selling
Securityholders agreed  with  the  Company  (i)  not  to  exercise  the  Selling
Securityholder Warrants for a period of one year for the closing of the Offering
and  (ii) not to sell the Selling Securityholder Warrants except pursuant to the
restrictions set forth below:

    The Underwriter also  has demand and  "piggy-back" registration rights  with
respect   to   the   securities  underlying   the   Underwriter's   Option.  See
"Underwriting." In addition,  the Company  has granted  demand and  "piggy-back"
registration  rights to  the holders  of 1,326,166  shares of  Common Stock. See
"Description of Securities -- Registration Rights."
 
    Prior to the Offering, there  has been no market  for any securities of  the
Company,  and no predictions  can be made of  the effect, if  any, that sales of
Common Stock or  the availability  of Common  Stock for  sale will  have on  the
market  price of  such securities  prevailing from  time to  time. Nevertheless,
sales of  substantial  amounts  of  Common Stock  in  the  public  market  could
adversely affect prevailing market prices.
 
                                  UNDERWRITING
 
    D.H. Blair Investment Banking Corp., the Underwriter, has agreed, subject to
the  terms and  conditions of the  Underwriting Agreement, to  purchase from the
Company the 3,067,000  shares of Common  Stock, 3,067,000 Class  A Warrants  and
3,067,000  Class B Warrants offered hereby on  a "firm commitment" basis, if any
are purchased. It  is expected that  Blair &  Co. will distribute  as a  selling
group  member substantially all of the Common Stock and Warrants offered hereby.
It is  also expected  that Blair  &  Co. will  make a  market in  the  Company's
securities  following the Offering. Blair & Co. is substantially owned by family
members  of  J.  Morton  Davis,  including  limited  partners  of  a   principal
stockholder  of the Company.  See "Certain Transactions." Mr.  Davis is the sole
stockholder of the Underwriter.
 
    The Underwriter has advised the Company that it proposes to offer the Shares
and Warrants to the public at the public offering prices set forth on the  cover
page  of this Prospectus and to certain dealers  who are members of the NASD, at
such prices less concessions of not in excess of $.10 per Share, $.001 per Class
A Warrant and $.001 per Class  B Warrant, of which a  sum not in excess of  $.05
per Share, $.0005 per Class A Warrant and $.0005 per Class B Warrant may in turn
be  reallowed  to  other  dealers  who  are  members  of  the  NASD.  After  the
commencement of the offering, the public offering prices, the concession and the
reallowance may be changed by the Underwriter.
 
    The  Company  has  agreed  to  indemnify  the  Underwriter  against  certain
liabilities,  including liabilities  under the  Securities Act.  The Company has
also agreed to pay to the Underwriter a non-accountable expense allowance  equal
to 3% of the gross proceeds derived from the sale of Shares and Warrants offered
hereby,   including  any   Shares  and   Warrants  purchased   pursuant  to  the
Underwriter's overallotment option, $20,000 of which has been paid to date.
 
    The Company has granted to the Underwriter an option exercisable during  the
30-day  period commencing on the  date of this Prospectus,  to purchase from the
Company at the public offering price, less underwriting discounts, up to 460,050
additional shares of Common Stock and/or 460,050 Class A Warrants and/or 460,050
Class B Warrants for the purpose of covering over-allotments, if any.
 
    The holders of approximately 98% of  the shares of Common Stock  outstanding
prior  to the Offering  (after giving effect  to the conversion  of the Series A
Preferred Stock), and the holders of  all of the Company's options and  warrants
outstanding  prior to the Offering, have agreed not to sell, assign, transfer or
otherwise dispose publicly of any of their  shares of Common Stock for a  period
of 13 months from the
 
                                       69
<PAGE>
date  of this Prospectus  without the prior written  consent of the Underwriter.
The holders of  740,559 shares of  Common Stock and  options to purchase  71,923
shares  of Common Stock  have deposited such  shares and options  into escrow as
described under "Principal Stockholders -- Escrow Securities."
 
    The  Company  has  agreed  to  nominate  one  director  designated  by   the
Underwriter  to the Company's Board of Directors for a period of five years from
the completion  of the  Offering, although  it  has not  yet selected  any  such
designee.  Such  designee  may  be a  director,  officer,  partner,  employee or
affiliate of the Underwriter.
 
    During the five-year period from the  date of this Prospectus, in the  event
the  Underwriter originates a financing or  a merger, acquisition or transaction
to which the Company is a party,  the Underwriter will be entitled to receive  a
finder's  fee in consideration  for origination of such  transaction. The fee is
based on a percentage of the consideration paid in the transaction ranging  from
7%  of  the  first  $1,000,000 to  2  1/2%  of any  consideration  in  excess of
$9,000,000.
 
    The Company has agreed not to  solicit Warrant exercises other than  through
the Underwriter, unless the Underwriter declines to make such solicitation. Upon
any  exercise of the  Warrants after the  first anniversary of  the date of this
Prospectus, the Company will pay  the Underwriter a fee  of 5% of the  aggregate
exercise  price of the Warrants, if (i) the market price of the Company's Common
Stock, on the date the Warrants are exercised is greater than the then  exercise
price  of  the Warrants;  (ii) the  exercise  of the  Warrants was  solicited in
writing by  a  member  of the  NASD;  (iii)  the  Warrants are  not  held  in  a
discretionary  account; (iv)  disclosure of  compensation arrangements  was made
both at the time of  the Offering and at the  time of exercise of the  Warrants;
and (v) the solicitation of exercise of the Warrant was not in violation of Rule
10b-6 promulgated under the Exchange Act.
 
    Rule  10b-6 may  prohibit Blair  & Co.  from engaging  in any  market making
activities with regard  to the  Company's securities  for the  period from  nine
business  days (or such other applicable period as Rule 10b-6 may provide) prior
to any solicitation  by the Underwriter  of the exercise  of Warrants until  the
later  of the termination  of such solicitation activity  or the termination (by
waiver or otherwise) of any right that the Underwriter may have to receive a fee
for the exercise of Warrants following  such solicitation. As a result, Blair  &
Co.  may  be unable  to provide  a  market for  the Company's  securities during
certain periods while the Warrants are exercisable.
 
    The Company has  agreed to sell  to the Underwriter  and its designees,  for
nominal consideration, the Underwriter's Option to purchase up to 306,700 shares
of Common Stock and/or 306,700 Class A Warrants and/or 306,700 Class B Warrants,
substantially  identical to the Shares and Warrants being offered hereby, except
that the Class A Warrants and Class  B Warrants included therein are subject  to
redemption  by the Company at  any time after the  Underwriter's Option has been
exercised and the underlying warrants are outstanding. The Underwriter's  Option
will  be exercisable during the three-year  period commencing two years from the
date of this Prospectus at an exercise price of $6.16 per share of Common Stock,
$.07 per Class A Warrant and $.07 per Class B Warrant, subject to adjustment  in
certain  events  to protect  against dilution,  and are  not transferable  for a
period of two years from the date  of this Prospectus except to officers of  the
Underwriter  or  to members  of the  selling  group. The  Company has  agreed to
register during the four-year period commencing  one year from the date of  this
Prospectus,  on two  separate occasions,  the securities  issuable upon exercise
thereof under the  Securities Act, the  initial such registration  to be at  the
Company's   expense  and  the  second  at   the  expense  of  the  holders.  The
Underwriter's Option  includes a  provision  permitting the  holder to  elect  a
cashless   exercise.  The   Company  has   also  granted   certain  "piggy-back"
registration rights to holders of the Underwriter's Option.
 
    The Underwriter has informed  the Company that it  does not expect sales  to
discretionary accounts.
 
    The  Underwriter  acted  as  Placement Agent  for  the  Bridge  Financing in
December 1995 for  which it received  a Placement  Agent fee of  $222,500 and  a
non-accountable expense allowance of $66,750.
 
    The  Commission is  conducting an investigation  concerning various business
activities of the Underwriter and Blair & Co., a selling group member which will
distribute substantially  all of  the Shares  and Warrants  offered hereby.  The
investigation  appears to be  broad in scope, involving  numerous aspects of the
 
                                       70
<PAGE>
Underwriter's and Blair & Co.'s compliance with the federal securities laws  and
compliance  with the  federal securities laws  by issuers  whose securities were
underwritten by the Underwriter or Blair &  Co., or in which the Underwriter  or
Blair   &  Co.  made  over-the-counter  markets,  persons  associated  with  the
Underwriter or Blair & Co., such issuers and other persons. The Company has been
advised by the  Underwriter that  the investigation  has been  ongoing since  at
least  1989 and that  it is cooperating with  the investigation. The Underwriter
cannot predict whether this investigation will ever result in any type of formal
enforcement action against the  Underwriter or Blair &  Co., or, if so,  whether
any  such  action  might  have  an adverse  effect  on  the  Underwriter  or the
securities offered hereby. The  Company has been advised  that Blair & Co.  will
make  a  market  in  the  securities  following  the  Offering.  An  unfavorable
resolution of the Commission's investigation  could have the effect of  limiting
such  firm's ability to make  a market in the  Company's securities, which could
affect the liquidity or price of such securities.
 
    Prior to  the Offering,  there has  been no  public market  for any  of  the
securities offered hereby. Accordingly, the public offering prices of the Shares
and  Warrants offered hereby and the terms  of the Warrants have been determined
by negotiation between the Company and  the Underwriter and are not  necessarily
related to the Company's asset value, net worth or other established criteria of
value.  Factors considered in determining such  prices and terms, in addition to
prevailing market conditions, include the history  of and the prospects for  the
industry  in  which the  Company competes,  the present  state of  the Company's
development and its future prospects, an assessment of the Company's management,
the Company's capital structure and such other factors as were deemed relevant.
 
    VentureTek L.P., a limited partnership whose limited partners consist of the
children and  grandchildren of  J. Morton  Davis, the  sole stockholder  of  the
Underwriter,   and  The  Long   Term  Equity  Holdings   Trust,  a  trust  whose
beneficiaries consist of the grandchildren of Mr. Davis, beneficially own in the
aggregate approximately 14.4%  of the  outstanding Common Stock  of the  Company
prior  to the Offering. See "Principal Stockholders" and "Certain Transactions."
As a result of such stockholdings, the Underwriter may be deemed an affiliate of
the Company by  the NASD. Accordingly,  the Offering is  being made pursuant  to
Schedule  E to  the By-Laws of  the NASD. In  accordance with Schedule  E to the
By-Laws of the NASD, the independent  investment banking firm of RAS  Securities
Corp.  ("RAS") has recommended a maximum  initial public offering price of $4.40
per Share, $.05 per Class  A Warrant and $.05 per  Class B Warrant. Pursuant  to
Schedule E to the NASD By-Laws, the Shares and the Warrants are being offered at
a  price no greater than the maximum recommended by RAS, which firm has informed
the Company that it  has performed "due diligence"  with respect to  information
contained  in the Registration Statement of which  this Prospectus is a part and
has participated in the preparation of the Registration Statement. The NASD  and
the  Commission  have indicated  that, in  their  view, a  qualified independent
underwriter, such as RAS,  may be deemed  to be an underwriter,  as the term  is
defined  in the Securities Act. The Underwriter will pay a fee of $50,000 to RAS
for its  services in  connection with  recommending the  maximum initial  public
offering  price of  the Shares  and Warrants in  this offering.  The Company has
agreed to indemnify RAS against certain liabilities, including liabilities under
the Securities Act.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Conversion Technologies International, Inc.
 
    We  have audited the  accompanying consolidated balance  sheet of Conversion
Technologies International, Inc. and Subsidiary (Company) at June 30, 1995,  and
the  related consolidated statements of operations, stockholders' deficiency and
cash flows for the period from March 1, 1994 (date operations commenced) to June
30, 1994 and the year ended June 30, 1995. We have also audited the accompanying
statements of operations,  stockholders' deficiency  and cash  flows of  Dunkirk
International  Glass and Ceramics  Corporation (Predecessor) for  the year ended
June 30,  1994  and  the two  months  ended  August 31,  1994.  These  financial
statements   are  the   responsibility  of   the  Companies'   managements.  Our
responsibility is to express an opinion  on these financial statements based  on
our audits.
 
    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all  material respects,  the consolidated  financial position  of  Conversion
Technologies  International,  Inc.  and Subsidiary  at  June 30,  1995,  and the
consolidated results of  their operations  and cash  flows for  the period  from
March  1, 1994 (date operations  commenced) to June 30,  1994 and the year ended
June 30, 1995 and Dunkirk International Glass and Ceramics Corporation's results
of operations and cash flows for the year ended June 30, 1994 and the two months
ended  August  31,  1994  in  conformity  with  generally  accepted   accounting
principles.
 
    The  accompanying financial statements have  been prepared assuming that the
Company will continue as a going concern. As more fully described in Note 3, the
Company has  generated only  minimal revenue,  has incurred  significant  losses
since  inception,  has a  working capital  and  stockholders' deficiency  and is
dependent upon  additional funding.  These  conditions raise  substantial  doubt
about  the  Company's ability  to  continue as  a  going concern.  The financial
statements do not include any adjustments to reflect the possible future effects
on  the  recoverability  and  classification  of  assets  or  the  amounts   and
classification of liabilities that may result from the possible inability of the
Company to continue as a going concern.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 1995
  (AMOUNTS AND DISCLOSURES INCLUDED FOR MARCH 31, 1995 AND 1996 ARE UNAUDITED)
 
1.  ORGANIZATION
    Conversion  Technologies International, Inc. (the  "Company") is a specialty
materials company (i) manufacturing industrial abrasives marketed under the name
ALUMAGLASS-TM-, (ii) processing  certain glass  and ceramic  materials, such  as
cathode  ray tube (CRT) glass, for resale to original manufacturers or others or
converting such materials into manufacturing  raw materials for the Company  and
others  and  (iii)  developing  certain  other  technologies.  The  Company  has
developed products and services to meet the  needs of a number of its  strategic
industrial  partners and to  potentially serve large  international markets. The
Company's revenue  streams  are  a  combination of  waste  conversion  fees  and
manufactured product sales.
 
    On  June 10,  1994, the Company  authorized a  four for one  stock split and
reduced the  common stock  par value  to $.00025  per share.  Additionally,  the
Company  increased its common and preferred  shares authorized to 25,000,000 and
15,000,000, respectively.
 
2.  ACQUISITION OF DUNKIRK INTERNATIONAL GLASS AND CERAMICS CORPORATION
    Effective August 31, 1994,  Conversion Technologies International, Inc.  and
Dunkirk  International Glass and Ceramics Corporation ("Dunkirk" or "Predecessor
Company")  completed  a  merger  whereby  the  common  shareholders  of  Dunkirk
exchanged  their common shares for 257,808  shares of the Company's common stock
valued at $13.55 per share (each common share of Dunkirk was converted to 49.107
common  shares  of   the  Company).  Prior   to  this  transaction,   Conversion
Technologies  International, Inc. had  owned 35 shares  of Dunkirk's Convertible
Series A Preferred Stock, which were cancelled upon the merger transaction.  The
Company  contributed $1.5 million to Dunkirk as a condition of the closing. This
transaction has  been accounted  for as  a purchase.  In conjunction  with  this
merger transaction, the Company recorded a charge against earnings of $6,232,459
relating  to the  write-off of purchased  research and  development (in process)
technology that had not reached  technological feasibility and, in  management's
opinion,  had  no alternative  future  use at  the  merger date.  The in-process
technology was  expensed on  the date  of acquisition.  As part  of this  merger
transaction, a portion of Dunkirk's debt was converted into 13,281 shares of the
Company's common stock at a conversion price of $20.36 per share.
 
    If  this  merger transaction  had occurred  on July  1, 1994,  the Company's
consolidated revenue, net loss and pro forma  net loss per common share for  the
year ended June 30, 1995 would have been $1,235,716, ($12,974,814) and ($17.24),
respectively.
 
    As  of the date  of the merger  transaction, Dunkirk was  in the development
stage. Dunkirk was incorporated  on July 3, 1990,  for the purpose of  recycling
and  beneficially  reusing  industrial  waste  CRT  glass  and  converting other
industrial waste  materials  into  high  value  specialty  abrasives  and  other
glass-ceramic  materials. Dunkirk  started developing its  patented processes in
1991. CRT glass processing commenced in the summer of 1994 and Dunkirk commenced
production of its ALUMAGLASS-TM- family of  abrasives in the spring of 1995  and
accordingly,  the Company has exited  the development stage. Product application
testing and initial marketing of  ALUMAGLASS-TM- is currently underway.  Dunkirk
incurred  cumulative net losses of  approximately $2,845,000 from its inception,
July 3, 1990 to August 31, 1994. In addition, as of August 31, 1994, Dunkirk had
a working capital  deficiency of  approximately $2,728,000  and a  shareholders'
deficiency  of approximately $1,240,000 which  includes the above mentioned $1.5
million capital contribution from the Company.

3.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    The accompanying consolidated financial statements  have been prepared on  a
going  concern  basis  which  contemplates the  realization  of  assets  and the
liquidation of liabilities in the ordinary  course of business. The Company  has
had  limited revenue, has incurred significant  losses since inception which has
resulted in a working capital and stockholders' deficiency and has only  limited
available  borrowing facilities for  working capital. In  view of the foregoing,
continuation of the Company as a going concern depends on its ability to achieve
profitability through  an  adequate  revenue  stream  and/or  obtain  additional
funding.  The accompanying consolidated financial  statements do not include any
adjustments relating to the realization of assets and liquidation of liabilities
that might be  necessary should the  Company be  unable to continue  as a  going
concern.
 
    Management  is  in active  discussions  with several  additional  sources of
capital and is also in discussions with several potential strategic partners  to
assist in the Company's commercialization plans.
 
    The  consolidated financial statements and related notes thereto as of March
31, 1996 and for the nine months ended March 31, 1995 and 1996 are unaudited and
have been prepared in  a manner consistent with  the preparation of the  audited
consolidated financial statements of the Company included herein. In the opinion
of  management,  such unaudited  consolidated  financial statements  reflect all
adjustments (consisting  of  normal recurring  accruals)  necessary for  a  fair
presentation of the financial position, results of operations and cash flows for
the interim periods presented.
 
PRINCIPLES OF CONSOLIDATION
 
    The  consolidated financial  statements include  the accounts  of Conversion
Technologies  International,  Inc.  and  its  wholly-owned  subsidiary,  Dunkirk
International  Glass  and Ceramics  Corporation.  The consolidated  statement of
operations and cash flows for the nine months ended March 31, 1995 and the  year
ended June 30, 1995 include the results of Dunkirk from August 31, 1994 (date of
merger).   Intercompany  accounts  and  transactions  have  been  eliminated  in
consolidation.
 
REVENUE RECOGNITION
 
    The Company derives most of its  revenue from a combination of fees  charged
to accept waste materials and from the sale of its products. Revenue recognition
of  the fees charged to accept the waste material is deferred until the material
is placed through the conversion process.
 
    For the year ended June 30, 1995, 90.8% of the Company's revenue was derived
from three  major customers.  Revenue  generated from  each of  these  customers
amounted  to $436,246, $387,752  and $241,838 which  represents 37.2%, 33.0% and
20.6% of total revenue, respectively.
 
RESERVE FOR DISPOSAL
 
    Dunkirk began accepting waste materials (primarily CRT glass) in early 1994.
Upon accepting  the  waste materials,  Dunkirk  established a  reserve  for  the
potential disposal costs for the waste materials accepted, in the event that the
conversion  processes being  developed were not  successful. For  the year ended
June 30, 1994 and two months  ended August 31, 1994, Dunkirk recorded  additions
of  $290,000 and $135,000,  respectively, to this reserve.  From August 31, 1994
(date of merger) to June 30, 1995, the Company recorded an addition of  $935,000
to  this reserve. From July  1, 1995 to March 31,  1996, the Company reduced the
reserve by approximately $539,000. The increases/decreases in the reserve, which
substantially resulted  from  changes in  the  volume of  inventory,  have  been
charged/credited  against operations. The Company  intends to adjust the reserve
when the conversion processes prove commercially successful.

</TABLE>
 
PROPERTY, PLANT AND EQUIPMENT
 
    Property,  plant and  equipment is stated  at cost.  The Company capitalized
interest costs of $63,499 and $361,512 for the year ended June 30, 1995 and nine
months ended March 31,  1996, respectively, with regard  to the construction  of
certain  long-term  assets. Depreciation  and  amortization is  computed  on the
straight-line method over the estimated useful lives of the assets. Amortization
of assets under  capital leases is  provided on a  straight-line basis over  the
lesser of the useful lives of the related assets or the terms of the leases.
 
CASH EQUIVALENTS
 
    The  Company  considers  all  highly-liquid  investments  with  an  original
maturity of three months or less to be cash equivalents.
 
INCOME TAXES
 
    Deferred income  tax assets  and liabilities  are recorded  for  differences
between  the financial  statement and tax  bases of assets  and liabilities that
will result in taxable or deductible amounts in the future based on enacted  tax
laws  and rates applicable to the periods  in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary to
reduce deferred tax  assets to the  amount expected to  be realized. Income  tax
expense is the tax payable or refundable for the period plus or minus the change
during the period in deferred tax assets and liabilities.
 
PROCESS DEVELOPMENT COSTS
 
    Process development costs represent research and development associated with
the   Company's   CRT   glass  processing   and   ALUMGLASS-TM-   product  lines
(technologies) since the date of the merger transaction.
 
PRO FORMA NET LOSS PER COMMON SHARE
 
    The pro forma net  loss per common share  is based on the  net loss for  the
relevant period or year, divided by the weighted average number of common shares
outstanding  during the period or year (excluding the common shares that will be
deposited into escrow in connection  with the Company's initial public  offering
- -- see Note 10). Common Stock equivalents such as stock options and warrants are
not included as their effect is anti-dilutive. However, immediately prior to the
closing  of the Company's  initial public offering (see  Note 10), the Company's
Series A  Preferred Stock  will be  converted into  1,023,054 shares  of  common
shares  (see Note 10). The weighted average number of these converted shares, at
June 30,  1994  and 1995  and  March 31,  1996  were 0,  587,742  and  1,023,054
respectively, and they have been included in the

related  pro forma  net loss  per common  share calculation.  Therefore, the pro
forma weighted average number of common shares outstanding at June 30, 1994  and
1995 and March 31, 1996 were 18,679, 734,754 and 1,185,387, respectively.
 
DEFERRED FINANCING COSTS
 
    Costs  related to  obtaining debt  financing are  being amortized  under the
interest method of accounting. During the nine months ended March 31, 1996,  the
Company incurred $375,250 and $420,324 of costs related to a Bridge Financing in
December  1995 and a  proposed initial public offering  ("IPO") of the Company's
securities, respectively (see  Note 10). The  deferred finance costs  associated
with  the Bridge Financing will be treated as an extraordinary loss upon payment
of such financing which will  be made upon the completion  of the IPO (see  Note
10).  The deferred finance costs associated with  the IPO will be netted against
equity when the proceeds are received.
 
RECLASSIFICATION
 
    Certain June 30, 1994 balances for Dunkirk have been reclassified to conform
to the current presentation.
 
PENDING ACCOUNTING PRONOUNCEMENT
 
    SFAS No. 121  "Accounting for the  Impairment of Long-Lived  Assets and  for
Long-Lived  Assets  to  be Disposed  of"  proscribes new  rules  for recognizing
impairments to property, plant and equipment. The standard is effective for  the
Company  no later than fiscal 1997. Assuming the Company can generate sufficient
revenue to achieve profitability and/or obtain additional financing,  management
believes this standard would have no impact on the Company.
 
4.  DEBT
 
    Long-term debt consists of the following obligations as of June 30, 1995:

</TABLE>
 
5.  NOTES PAYABLE
    In  August 1994, Conversion Technologies International, Inc. repaid $205,000
of promissory notes from a related party, which bore interest at 10% per annum.
 
    Dunkirk has a  $300,000 line of  credit with a  bank. At June  30, 1995  and
March 31, 1996, Dunkirk had borrowed $262,500 and 252,500, respectively, against
this  line. The line of credit is limited to a percentage of acceptable accounts
receivable. Interest is payable monthly at a bank-determined variable base  rate
plus  2.5%  (11.5% at  June 30,  1995).  The note  payable is  collateralized by
accounts receivable, a first priority lien on all finished manufactured products
and is guaranteed by the former Dunkirk president (see Note 10).
 
    Dunkirk has a $124,000 demand note payable to a bank (collateralized by  the
former  Dunkirk president's  certificate of deposit  having a  carrying value of
$130,000 at June 30, 1995 and March  31, 1996 -- see Note 10). Interest  accrues
and  is due monthly at a variable base  rate determined by the bank plus 1% (10%
at June 30, 1995).
 
6.  RESTRICTED ASSETS
    Dunkirk has $78,772 and $585 of project funds available at June 30, 1995 and
March 31, 1996,  respectively, for  the acquisition of  qualified machinery  and
equipment  from the unexpended balance  on the sale of  the solid waste disposal
facility bonds. In addition,  a debt service reserve  fund equivalent to 10%  of
the  bonds plus interest is required to be deposited in escrow ($508,291 at June
30, 1995 and  $833,671 at March  31, 1996) (see  Note 10), and  may be  released
under  certain conditions.  In anticipation  of the  Company's IPO,  $230,000 of
interest due at  December 1,  1995 and  again at March  1, 1996  on the  Dunkirk
Chautaqua  County Industrial  Development Agency  solid waste  disposal facility
bonds, a total of $460,000, was paid from the debt service reserve fund and must
be restored from the  proceeds of the  offering. As a  result of these  interest
payments,  the actual debt  service reserve fund  balance at March  31, 1996 was
reduced to $373,671.
 
    Dunkirk also  has  a  debt  service reserve  fund,  including  interest,  of
$406,845 at June 30, 1995 and $422,855 at March 31, 1996, deposited in escrow as
required  by the JDA  for payment of  the final installments  due on the related
debt.

8.  CAPITAL STOCK
    During fiscal  1995,  the  Company  issued  2,958,000  shares  of  Series  A
Preferred  Stock, par  value $.001,  at $2.50  per share  through private equity
placements. The  Series A  Preferred Stock  was convertible  into the  Company's
common stock on a one for one basis subject to certain anti-dilution provisions.
These   shares  are  now  convertible  on  an  approximate  0.1218-to-one  basis
concurrent with the Company's reverse common  stock split (see Note 10). In  the
event of involuntary or voluntary liquidation, the holders of Series A Preferred
Stock  are entitled to receive a liquidation preference out of the assets of the
Company legally available for distribution. The liquidation preference is  equal
to  the original issuance price per share plus any declared and unpaid dividends
thereon. Dividends are payable at the annual rate of 5% of the original issuance
price per share of Series A Preferred Stock, on a non-cumulative basis as, when,
and if  declared by  the Board  of Directors.  The Company  does not  intend  to
declare  dividends in the  foreseeable future. At  any time after  June 1, 1998,
upon not less  than thirty days  nor more  than sixty days  written notice,  the
Company may, at its option, redeem the Series A Preferred Stock, in whole, at an
amount  per share equal  to $2.50 plus  any declared and  unpaid dividends. Each
share of Series  A Preferred Stock  entitles the  holder to votes  equal to  the
number  of shares of common  stock into which such  shares are then convertible.
However, the affirmative votes of  the holders of at least  60% of the Series  A
Preferred Stock is required for certain transactions as outlined in the Restated
Certificate of Incorporation. (See Note 10.)

provisions to which  the Series A  Preferred Stock warrants  and certain  common
stock warrants are subject to (see Note 10).
 
    In  June  1994,  the Company  adopted  an  Employee Stock  Option  Plan (the
"Employee  Plan")  and   a  Non-Employee   Director  Stock   Option  Plan   (the
"Non-Employee  Plan"). Stock  options may  be granted  at the  discretion of the
Board of Directors.  The Company has  reserved 79,170 and  24,360 shares of  its
common  stock  for  issuance upon  the  exercise  of options  granted  under the
Employee and Non-Employee  Plans, respectively (see  Note 10). The  Non-Employee
Plan options are exercisable in full one year after the date of grant and expire
ten  years from  the date  of grant.  The Employee  Plan options  primarily vest
one-third on each  of the first  three anniversaries  of the date  of grant  and
expire on the seventh anniversary of the date of grant. The Company grants stock
options at exercise prices equal to or greater than the fair market value of the
Company's Common Stock on the date of grant.

</TABLE>
 
    The  above net deferred tax  asset has been reserved  because it is not more
likely than not that it would be recognized.
 
    At June 30,  1995, the Company  has approximately $5.8  million of tax  loss
carryforwards  (including approximately $1.5 million  generated by Dunkirk prior
to August 31,  1994) available  to offset  future taxable  income, which  expire
between 2006 and 2010. The Tax Reform Act of 1986 enacted a complex set of rules
limiting the potential utilization of net operating loss carryfowards in periods
following  a corporate  "ownership change." In  general, for  federal income tax
purposes, an ownership change is deemed to occur if the percentage of stock of a
loss corporation owned (actually, constructively and, in some cases, deemed)  by
one  or more "5% shareholders"  has increased by more  than 50 percentage points
over the  lowest percentage  of such  stock owned  during a  three year  testing
period.  Subsequent to August 31, 1994, such a change in ownership has occurred.
As a result of the  change, the Company's ability  to utilize its net  operating
loss  carryforwards generated by Dunkirk prior to August 31, 1994 (approximately
$1.5 million) will be limited.
 
10. SUBSEQUENT EVENTS
    On July 26, 1995, the Company issued an additional $3,000,000 (resulting  in
total  borrowings  of $8,000,000)  of  Chautauqua County  Industrial Development
Agency solid  waste disposal  facility bonds  with terms  similar to  the  bonds
included  in  Note  4. The  annual  principal  payments (on  the  total  debt of
$8,000,000) which begin on December 1, 1998 and end on December 1, 2010 increase
from $325,000 in 1998  to $1,025,000 in  2010. The proceeds  will and have  been
used  for the  purchase and installation  of equipment at  the Company's Dunkirk
facility.
 
    From the  period commencing  September 1995  and ending  November 1995,  the
Company  issued $700,000 of 6% convertible  promissory notes, in anticipation of
additional equity financing, of which $50,000 has been paid to date (see below).
 
    From the period commencing  December 7, 1995 and  ending December 15,  1995,
the  Company  obtained  additional  bridge  financing  ("bridge  loan")  in  the
principal amount of  $2,225,000, (recorded,  net of  the value  assigned to  the
attached  warrants, at $2,158,250) which includes  the conversion of $650,000 of
the $700,000 convertible promissory notes  discussed above. The bridge loan  was
issued  through a private placement arranged by the underwriter of the Company's
proposed initial  public  offering ("IPO")  (see  below). This  bridge  loan  is
comprised  of bridge units,  each consisting of  a bridge note  in the principal
amount of $50,000 bearing interest at the rate of 10% per annum, and warrants to
purchase 25,000 shares  of the Company's  common stock at  an exercise price  of
$4.00 per share commencing one year from the date of issuance and expiring three
years  after the initial closing date of the bridge loan offering. However, upon
the completion  of  the Company's  IPO,  the  related bridge  warrants  will  be
converted  into  the  equivalent  amount  of Class  A  warrants,  which  will be
registered in the Company's IPO.

                                 AND SUBSIDIARY
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                                 JUNE 30, 1995
  (AMOUNTS AND DISCLOSURES INCLUDED FOR MARCH 31, 1995 AND 1996 ARE UNAUDITED)
 
10. SUBSEQUENT EVENTS (CONTINUED)
    In March 1996, the Company issued $200,000 of promissory notes, due upon the
earlier of  the closing  of the  IPO and  six months  from the  date issued,  to
certain  directors, officers and securityholders which  bear interest at 10% per
annum. In May  1996, the  Company issued  an additional  $200,000 of  promissory
notes  to a  securityholder with  identical terms to  the notes  issued in March
1996.
 
    On October  2, 1995,  the Board  of Directors  approved a  letter of  intent
relating  to an initial public  offering of the Company's  common stock, Class A
warrants and Class B warrants.  Upon the closing of  the offering, the Series  A
Preferred  Stock will be  converted into 1,023,054  shares of common  stock as a
result of the restatement  of the Company's  Certificate of Incorporation  which
will  adjust the Series A Preferred  Stock conversion ratio due to anti-dilution
provisions and the reverse split of  the Company's common stock (see below).  In
addition,  preferred  stock warrants  will become  exercisable for  common stock
(adjusted for a 0.1218-for-one reverse common stock split -- see below) and  the
number  of  common  shares into  which  certain  common stock  warrants  and all
preferred  stock  warrants  are  convertible,  will  increase  by  a  factor  of
approximately 2.84 upon the effective date of the IPO due to the fact that those
warrants  have protection against the dilutive effect of the valuation placed on
the Company upon  the IPO. In  connection with  the IPO, 740,559  shares of  the
Company's  common stock  and options to  purchase 71,923 shares  of Common Stock
(the "Escrow Securities") will be deposited into escrow by the holders  thereof.
The Escrow Securities will only be released from escrow when the Company attains
certain  earnings  levels or  the  market price  of  the Company's  common stock
achieves certain levels. These Escrow Securities are subject to cancellation  if
such conditions are not achieved.
 
    On  November  9,  1995,  the  Board  of  Directors  approved  an approximate
0.1218-for-one reverse split of its common stock. The accompanying  consolidated
financial  statements have been  retroactively restated to  reflect this reverse
stock split.
 
    On November 9,  1995, the Board  of Directors approved  an amendment to  the
1994  Employee Stock  Option Plan and  Non-Employee Director  Stock Option Plan,
effective upon the closing of the IPO, so as to increase the number of shares of
common stock available  thereunder to 440,000  and 70,400 shares,  respectively.
The  Company will also, upon the effective  date of the IPO, adjust the exercise
price of all the options and warrants outstanding prior to the IPO to $4.40 with
certain warrants  having an  exercise price  equal to  $4.40 plus  a premium  in
certain circumstances.
 
    In  December 1995,  the Company  agreed to  indemnify and  hold harmless the
former Dunkirk president with respect to guarantees made by him for  obligations
of  Dunkirk. In addition,  the Company agreed  to use its  reasonable efforts to
cause the release of such guarantees following the IPO.
 
    The Company is a party to litigation commenced by the Company in the Supreme
Court of New York, County of  Chautauqua, against a general contractor hired  to
construct  the improved abrasives finishing area, which is part of the Company's
current capital expansion program. The contractor commenced work in April  1995,
but was asked to stop work in November 1995 following significant cost overruns,
problems and delays in construction and disputes with the Company over the scope
of  the work  to be  performed by the  contractor. Each  of the  Company and the
contractor have filed and  served a summons with  notice. The contractor  claims
damages  of approximately $425,000.  The Company has  served the contractor with
its complaint,  alleging, among  other  things, breach  of contract,  fraud  and
defamation,  and seeks damages in  excess of $1,000,000. Until  such time as the
contractor serves the Company with its answer, the precise counterclaims of  the
contractor cannot be ascertained. The Company has engaged an engineering firm to
review  the contractor's work and oversee  completion of the abrasives finishing
area.
 
    The Company  does not  believe  that an  adverse  outcome in  the  foregoing
dispute would have a material adverse effect on the Company.
