the holder's broker, dealer, commercial bank, trust company or other nominee to
effect the transaction for the holder.  A stockholder having Shares registered
in the name of a broker, dealer, commercial bank, trust company or other nominee
must contact such broker, dealer, commercial bank, trust company or other
nominee if such stockholder desires to tender such Shares.  A stockholder who
desires to tender Shares and whose certificates for such Shares are not
immediately available or who cannot comply in a timely manner with the procedure
for book-entry transfer may tender such Shares by following the procedures for
guaranteed delivery set forth in Section 3.

To All Holders of Common Stock of
Resource Recycling Technologies, Inc.:

                                  INTRODUCTION

  WMI Acquisition Sub, Inc., a Delaware corporation (the "Purchaser") and a
wholly-owned subsidiary of Waste Management, Inc., an Illinois corporation (the
"Parent"), hereby offers to purchase all outstanding shares of Common Stock, par
value $1.00 (the "Shares"), of Resource Recycling Technologies, Inc., a Delaware
corporation (the "Company"), at $11.50 per Share, net to the seller in cash,
upon the terms and subject to the conditions set forth in this Offer to Purchase
and in the related Letter of Transmittal (which together constitute the
"Offer"). Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 7 of the Letter of
Transmittal, transfer taxes on the purchase of Shares pursuant to the Offer.
The Purchaser will pay all charges and expenses of Harris Trust Company of New
York (the "Depositary") and Morrow & Co., Inc. (the "Information Agent")
incurred in connection with the Offer.

  The Offer is being made pursuant to an Agreement and Plan of Merger dated
March 17, 1995 among the Purchaser, the Parent and the Company (the "Merger
Agreement"), pursuant to which, as soon as practicable following the completion
of the Offer and subject to certain conditions, the Purchaser will be merged
with and into the Company (the "Merger"). The Merger Agreement provides that the
Offer will be the first step in the Parent 's proposed acquisition of the entire
equity interest in the Company.  In the Merger, the Company will continue as the
surviving corporation and each Share outstanding as of the effective time of the
Merger (except those Shares that are owned by the Company as treasury shares or
are owned by the Purchaser, the Parent, their corporate affiliates, or by
stockholders who have perfected appraisal rights) will be converted into the
right to receive the highest price per Share paid in the Offer in cash, without
interest (the "Merger Consideration").  See Section 11.

  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER, HAS
DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR TO AND IN THE
BEST INTERESTS OF THE COMPANY'S STOCKHOLDERS AND RECOMMENDS THAT THE COMPANY'S
STOCKHOLDERS ACCEPT THE OFFER.

  Each of Allen & Company Incorporated and Gilford Securities Incorporated has
delivered to the Board of Directors of the Company its written opinion that,
based on certain considerations and assumptions, the $11.50 per Share price is
fair from a financial point of view to the stockholders of the Company.  Such
opinions are set forth in full as exhibits to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which is being mailed to the Company's stockholders together with this Offer to
Purchase.

  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF
SHARES REPRESENTING 50.1% OR MORE OF THE TOTAL NUMBER OF SHARES THAT WOULD BE
OUTSTANDING IF ALL OUTSTANDING RIGHTS TO ACQUIRE SHARES WERE EXERCISED (THE
"MINIMUM CONDITION").  THE OFFER IS ALSO SUBJECT TO OTHER CONDITIONS.  SEE
SECTION 13.

  The Company has informed the Purchaser that, as of March 17, 1995, there were
2,675,773 Shares issued and outstanding, 573,863 Shares issuable upon exercise
of various outstanding options and warrants to purchase Shares and 6,509 Shares
issuable upon conversion of outstanding convertible preferred stock.  See
Section 11.

  Consummation of the Merger is subject to the satisfaction or waiver of a
number of conditions, including approval by the stockholders of the Company if
required by law.  Under Delaware law, the affirmative vote of the holders of a
majority of the outstanding Shares is required to approve the Merger.  The
Purchaser will be entitled to vote all Shares owned by it in any stockholder
vote.  Consequently, if the Purchaser acquires or controls the vote of, whether
pursuant to the Offer or otherwise, more than 50% of the total Shares
outstanding on the record date for such vote, the Purchaser will have sufficient
voting power to approve the Merger without the vote of any other stockholder of
the Company.  If the Purchaser holds at least 90% of the Shares issued and
outstanding on the record date for the vote on the Merger, the Purchaser will be
permitted to effect, and intends to effect, the Merger without the approval of
any other stockholder of the Company.  Holders of approximately 33% of the
outstanding Shares
<PAGE>
 
(on a fully diluted basis) have agreed to tender the Shares beneficially owned
by them pursuant to the Offer.  See Section 11.  Holders of Shares who do not
vote for the Merger will have the right to exercise appraisal rights in
accordance with the Delaware General Corporation Law (the "DGCL").  See Section
11.

  The Company has informed the Purchaser that on March 13, 1995 there were
approximately 408 record holders of Shares.

  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH RESPECT TO THE
OFFER.

                                   THE OFFER

  1.  TERMS OF THE OFFER. Upon the terms and subject to the conditions set forth
in the Offer, the Purchaser will accept for payment and pay for all outstanding
Shares validly tendered prior to the Expiration Date and not theretofore
withdrawn in accordance with the procedures set forth in Section 4.  The term
"Expiration Date" means 12:00 Midnight, New York City time, on Wednesday, April
19, 1995, unless and until the Purchaser shall have extended the period of time
for which the Offer is open, in which event the term "Expiration Date" will mean
the latest time and date at which the Offer, as so extended by the Purchaser,
shall expire.

  The Purchaser expressly reserves the right, at any time or from time to time,
in its sole discretion, to extend the period during which the Offer is open
(except that the Company's consent is required other than for an extension (i)
not to exceed 20 business days, if at any scheduled Expiration Date, any of the
conditions to Purchaser's obligations to accept for payment, and pay for, Shares
shall not have been satisfied or waived, (ii) for any period required by any
rule, regulation, interpretation or position of the Securities and Exchange
Commission (the "SEC") or the staff thereof applicable to the Offer, or (iii) of
not more than 15 business days beyond the latest expiration date that would be
permitted by the preceding clause (i) or (ii) if there shall not have been
tendered sufficient Shares so that the Merger could be effected as described
above in the fifth sentence of the seventh paragraph under "Introduction"), by
giving oral or written notice of such extension to the Depositary and by making
a public announcement of such extension in a manner reasonably designed to
inform the holders of Shares thereof.  If (i) the Purchaser decides, in its sole
discretion, to increase the consideration offered in the Offer to holders of
Shares or to waive any material condition to the Offer or, subject to the
approval of the Company, to decrease or change the form of the consideration
offered to such holders or to make, subject to the terms of the Merger
Agreement, any other change in the terms or conditions of the Offer (except to
waive any existing condition other than the Minimum Condition) in a manner
adverse to the holders of Shares and (ii) at the time that notice of such
increase, decrease, waiver or change is first published, sent or given to
holders of Shares in the manner specified below, the Offer is scheduled to
expire at any time earlier than the expiration of a period ending on the tenth
business day from, and including, the date that such notice is first so
published, sent or given, then the Offer will be extended until the expiration
of such period of ten business days.  As used herein, the term "business day"
means any day other than a Saturday, Sunday or federal holiday, and consists of
the time period from 12:01 a.m. through 12:00 midnight, New York City time.

  The Merger Agreement provides that neither the Parent nor the Purchaser will,
without the prior written consent of the Company, decrease or change the form of
the consideration payable in the Offer or decrease the number of Shares sought
pursuant thereto, change the terms or conditions of the Offer (except to waive
any existing conditions other than the Minimum Condition) in a manner adverse to
the holders of Shares or impose any additional conditions to the Offer.  See
Section 13.  The Company has agreed that no Shares held by the Company will be
tendered pursuant to the Offer.

  The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition and the expiration or termination of the waiting period
applicable to the Purchaser's acquisition of Shares pursuant to the Offer under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules and
regulations thereunder (collectively, the "HSR Act"). See Section 13, which
describes additional conditions to the Offer.  If, by the Expiration Date, any
or all of such conditions have not been satisfied, the Purchaser reserves the
right, in its sole 

                                       2
<PAGE>
 
discretion (i) to decline to accept for payment or pay for any of the Shares
tendered, terminate the Offer and return all tendered Shares to tendering
stockholders, (ii) to extend the Offer and, subject to the withdrawal rights
described in Section 4, retain the Shares that have been tendered until the
expiration of the Offer as extended or (iii) to waive such unsatisfied condition
or conditions (other than the Minimum Condition, which requires the Company's
consent) and, in accordance with applicable law and subject to any requirement
to extend the period of time during which the Offer is open, accept for payment
and pay for all Shares validly tendered by the Expiration Date and not properly
withdrawn.

  Any extension, delay in acceptance for payment or payment, termination or
amendment will be followed as promptly as practicable by public announcement
thereof, such announcement, in the case of an extension, to be issued no later
than 9:00 a.m., New York City time, on the next business day after the
previously scheduled Expiration Date.  The Purchaser will disseminate public
announcements concerning material changes to the Offer in accordance with
applicable law.  The manner in which the Purchaser will make any such public
announcement may, if appropriate, be limited to a release to the Dow Jones News
Service.

  The Purchaser's right to delay payment for Shares that it has accepted for
payment is limited by Rule 14e-1(c) under the Securities Exchange Act of 1934
(the "Exchange Act"), which requires that a bidder must pay the consideration
offered or return the securities deposited by or on behalf of security holders
promptly after the termination or withdrawal of a tender offer.  If the
Purchaser makes a material change in the terms of the Offer or the information
concerning the Offer, or waives a material condition of the Offer, the Purchaser
will disseminate additional tender offer materials to the extent required under
Rules 14d-4(c) and 14d-6(d) under the Exchange Act, and will extend the Offer to
the extent required by applicable law in order to permit stockholders adequate
time to consider such materials.  The SEC has taken the position that the
minimum period during which a tender offer must remain open following material
changes in the terms of the offer or information concerning the offer, other
than a change in the price or in the percentage of securities sought, will
depend upon the facts and circumstances, including the relative materiality of
the terms or information, and that, with respect to a change in the price or in
the percentage of securities sought, a minimum ten business day period may be
required to allow for adequate dissemination to stockholders and investor
response.

  The Company has provided the Purchaser with the Company's stockholder lists
and security position listings for the purpose of disseminating the Offer to
holders of Shares.  This Offer to Purchase and the related Letter of Transmittal
will be mailed by the Purchaser to holders of record of Shares on the date
hereof, and will be furnished by the Purchaser to brokers, dealers, banks, trust
companies and similar persons whose names, or the names of whose nominees,
appear on the stockholder lists (or, if applicable, who are listed as
participants in a clearing agency's security position listing) for subsequent
transmittal to beneficial owners of Shares.

  2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES. Upon the terms and subject
to the conditions of the Offer (including, if the Offer is extended or amended,
the terms and conditions of any such extension or amendment), the Purchaser will
accept for payment and thereby purchase, and will pay for, all Shares validly
tendered prior to the Expiration Date (and not withdrawn pursuant to Section 4)
as soon as practicable after the Expiration Date, which is anticipated to occur
after the latest of (i) the initial Expiration Date, (ii) the expiration or
termination of the waiting period applicable to the Purchaser's acquisition of
Shares pursuant to the Offer under the HSR Act, and (iii) the satisfaction or
waiver of all other conditions to the Offer set forth in Section 13.

  In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of (i) certificates for such Shares
or timely confirmation (a "Book-Entry Confirmation") of the book-entry transfer
of such Shares into the Depositary's account at The Depository Trust Company,
the Midwest Securities Trust Company or the Philadelphia Depository Trust
Company (collectively, the "Book-Entry Transfer Facilities") pursuant to the
procedures set forth in Section 3, (ii) a properly completed and duly executed
Letter of Transmittal or facsimile thereof with any required signature
guarantees or an "Agent's Message" and (iii) all other documents required by the
Letter of Transmittal.  The term "Agent's Message" means a message, transmitted
by a Book-Entry Transfer Facility to, and received by, the Depositary and
forming a part of a Book-Entry Confirmation, which states that such Book-Entry
Transfer Facility has received an express acknowledgment from the participant in

                                       3
<PAGE>
 
such Book-Entry Transfer Facility tendering the Shares which are the subject of
such Book-Entry Confirmation that such participant has received and agrees to be
bound by the terms of the Letter of Transmittal and that the Purchaser may
enforce such agreement against such participant.

  The Parent and the Company have each filed a Notification and Report Form
under the HSR Act with respect to the Offer.  The waiting period with respect to
the Offer under the HSR Act will expire at 11:59 p.m., New York City time, on
April 4, 1995, unless such waiting period is earlier terminated.  Prior to the
expiration of the waiting period, however, the Federal Trade Commission (the
"FTC") or the Antitrust Division of the Department of Justice (the "Antitrust
Division") may extend the waiting period by requesting additional information
from the Parent or the Company.  If such a request is made, the waiting period
will expire at 11:59 p.m., New York City time, on the tenth calendar day after
the Parent or the Company, as the case may be, has substantially complied with
the request.  Only one extension of the waiting period pursuant to the request
for additional information is authorized by the HSR Act, and any further request
for additional information that may be made of the Parent or the Company will
not extend the waiting period without a court order or the consent of the Parent
or the Company.  For further information with respect to the HSR Act and
antitrust matters, see Section 14.

  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, tendered Shares if, as and when the Purchaser
gives oral or written notice to the Depositary of its acceptance for payment of
such Shares.  Payment for Shares accepted for payment pursuant to the Offer will
be made by deposit of the purchase price therefor with the Depositary, which
will act as agent for the tendering stockholders for purposes of receiving
payments from the Purchaser and transmitting such payments to the tendering
stockholders.  Under no circumstances will interest on the purchase price for
Shares be paid, regardless of any delay in making such payment.

  If the Purchaser extends the Offer, is delayed in its acceptance for payment
of, or payment for, Shares or is unable to accept for payment or pay for Shares
pursuant to the Offer for any reason, then, without prejudice to the Purchaser's
rights under this Offer to Purchase, the Depositary may, nevertheless, on behalf
of the Purchaser and subject to Rule 14e-1 under the Exchange Act, retain
tendered Shares, and such Shares may not be withdrawn, except to the extent
tendering stockholders are entitled to, and duly exercise, withdrawal rights as
described in Section 4.

  If any tendered Shares are not accepted for payment pursuant to the terms and
conditions of the Offer for any reason, or if certificates representing more
Shares than are tendered are submitted to the Depositary, certificates for such
unpurchased or untendered Shares will be returned, without expense to the
tendering stockholder (or, in the case of Shares tendered by book-entry transfer
of such Shares into the Depositary's account at a Book-Entry Transfer Facility
pursuant to the procedures set forth in Section 3, such Shares will be credited
to an account maintained within such Book-Entry Transfer Facility), as soon as
practicable following the expiration, termination or withdrawal of the Offer.

  If, prior to the Expiration Date, the Purchaser increases the consideration
offered to stockholders for Shares pursuant to the Offer, such increased
consideration will be paid to all stockholders whose Shares are purchased
pursuant to the Offer, whether or not such Shares have been tendered prior to
such increase in consideration.  The Purchaser reserves the right, in its sole
discretion, to transfer or assign to any one or more of the Parent 's direct or
indirect majority-owning or -owned parents or subsidiaries, in whole or in part
and from time to time, (i) the right to purchase Shares tendered pursuant to the
Offer, and (ii) Shares now or hereafter beneficially owned by the Purchaser.
Any transfer or assignment contemplated in this paragraph will not relieve the
Purchaser of its obligations under the Offer and will in no way prejudice the
rights of tendering stockholders to receive payment for Shares validly tendered
and accepted for payment pursuant to the Offer.

  3.  PROCEDURE FOR TENDERING SHARES. For a stockholder validly to tender Shares
pursuant to the Offer, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof), together with any required signature
guarantees (or an Agent's Message in connection with a book-entry delivery of
Shares) and any other required documents, must be received by the Depositary at
one of its addresses set forth on the back cover of this Offer to Purchase.  In
addition, (i) either certificates for such Shares must be received by the
Depositary, together 

                                       4
<PAGE>
 
with the Letter of Transmittal, at such address, or such Shares must be
delivered pursuant to the procedures for book-entry transfer set forth below and
a Book-Entry Confirmation received by the Depositary, in each case prior to the
Expiration Date, or (ii) the tendering stockholder must comply with the
procedures for guaranteed delivery set forth below.

  Book-Entry Transfer.  The Depositary will establish an account with respect to
the Shares at the Book-Entry Transfer Facilities for purposes of the Offer
within two business days after the date of this Offer to Purchase.  Any
financial institution that is a participant in any of the Book-Entry Transfer
Facilities' systems may make book-entry delivery of the Shares by causing a
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account at such Book-Entry Transfer Facility in accordance with that Book-Entry
Transfer Facility's procedure for such transfer.  Although delivery of Shares
may be effected through book entry transfer into the Depositary's account at a
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal or facsimile thereof, together with any required signature
guarantees (or an Agent's Message in connection with a book-entry transfer) and
any other required documents, must still be transmitted to, and received by, the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Date or the tendering stockholder must comply
with the procedures for guaranteed delivery set forth below.  Delivery of
documents (including an executed Letter of Transmittal) to a Book-Entry Transfer
Facility in accordance with such Book-Entry Transfer Facility's procedures does
not constitute delivery to the Depositary.

  THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING STOCKHOLDER.  IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

  TO PREVENT BACKUP FEDERAL INCOME TAX WITHHOLDING AT A 31% RATE ON PAYMENTS
MADE TO CERTAIN STOCKHOLDERS WITH RESPECT TO THE PURCHASE PRICE OF SHARES
PURCHASED PURSUANT TO THE OFFER, EACH HOLDER OF SHARES MUST, UNLESS AN EXEMPTION
APPLIES, PROVIDE THE DEPOSITARY WITH ITS CORRECT TAXPAYER IDENTIFICATION NUMBER
AND CERTIFY THAT SUCH HOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX
WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED AS PART OF THE LETTER
OF TRANSMITTAL.

  Signature Guarantees.  Signatures on all Letters of Transmittal must be
guaranteed by a firm or other entity identified in Rule 17Ad-15 under the
Exchange Act, including (as such terms are defined therein) any (i) bank, (ii)
broker, dealer, municipal securities dealer, municipal securities broker,
government securities dealer or government securities broker, (iii) credit
union, (iv) national securities exchange, registered securities association or
clearing agency or (v) savings association (in each case, an "Eligible
Institution"), acting in accordance with the procedures set forth in such Rule,
and which is a member in good standing of the Securities Transfer Agents
Medallion Program, unless the Shares tendered thereby are tendered (a) by a
registered holder of such Shares who has not completed either the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the Letter of Transmittal or (b) for the account of an Eligible
Institution.  See Instruction 1 of the Letter of Transmittal.  If the
certificates for Shares are registered in the name of a person other than the
signer of a Letter of Transmittal, or if payment is to be made or unpurchased or
untendered Shares are to be issued to a person other than the registered holder,
the certificates for Shares must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name or names of the registered
holder or holders appear on the certificates, with the signatures on the
certificates or stock powers guaranteed as provided in the Letter of
Transmittal.  See Instruction 5 of the Letter of Transmittal.

  Guaranteed Delivery.  If a holder of Shares desires to tender Shares pursuant
to the Offer and such holder's certificates are not immediately available, or
the procedure for book-entry transfer cannot be completed on a timely basis, or
such holder cannot deliver the certificates and all required documents to the
Depositary prior to the Expiration Date, such holder's tender may nevertheless
be effected if all the following conditions are complied with:

          (i)  such tender is made by or through a member firm of a registered
     national securities exchange, a member of the National Association of
     Securities Dealers, Inc. or a commercial bank or trust company having an
     office or correspondent in the United States (each, a "Guaranteeing
     Institution");

                                       5
<PAGE>
 
          (ii)  a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser herewith, is
     received by the Depositary as provided below prior to the Expiration Date;
     and

          (iii)  the certificates for all tendered Shares, in proper form for
     transfer (or a Book-Entry Confirmation), together with a Letter of
     Transmittal or facsimile thereof, properly completed and duly executed,
     with any required signature guarantees (or, in the case of a book-entry
     transfer, an Agent's Message) and any other documents required by the
     Letter of Transmittal, are received by the Depositary within five American
     Stock Exchange ("AMEX") trading days after the date of execution of such
     Notice of Guaranteed Delivery.

  The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
telegram, facsimile transmission or mail to the Depositary, and must include a
guarantee by a Guaranteeing Institution in the form set forth in such Notice of
Guaranteed Delivery.

  In all cases, payment for Shares purchased pursuant to the Offer will be made
only after timely receipt by the Depositary of certificates for such Shares, or
timely confirmation of a Book-Entry Confirmation relating to such Shares, and a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof) and any other required documents.

  By executing a Letter of Transmittal as set forth above, a tendering holder of
Shares sells, assigns and transfers to, or upon the order of, the Purchaser all
right, title and interest in all Shares so tendered and irrevocably appoints the
Depositary as an attorney-in-fact with full power of substitution (such power of
attorney being deemed to be an irrevocable power coupled with an interest) (i)
to deliver certificates for such Shares (and all other shares, dividends,
distributions, rights or other securities or property issued or issuable or
distributed or distributable in respect of such Shares on or after March 17,
1995 ("Distributions")) or transfer ownership of such Shares on the account
books maintained by Book-Entry Transfer Facilities, together in either such case
with all accompanying evidence of transfer and authenticity, all upon the order
of the Purchaser, (ii) to present such Shares (and any such Distributions) for
registration and transfer on the Company's books and (iii) to receive all
benefits and otherwise exercise all rights of beneficial ownership of such
Shares (and any such Distributions), all in accordance with the terms of the
Offer.

  By executing the Letter of Transmittal as set forth above, the tendering
stockholder will irrevocably appoint designees of the Purchaser as such
stockholder's proxies (such proxies being deemed to be an irrevocable proxy
coupled with an interest), each with full power of substitution, to the full
extent of such stockholder's rights with respect to the Shares tendered by such
stockholder (and any Distributions) and accepted for payment by the Purchaser
prior to the time of any stockholder vote.  Such appointment will be effective
when, and only to the extent that, the Purchaser accepts such Shares for
payment.  Upon such appointment, all prior proxies given by such stockholder
with respect to such Shares will be revoked and no subsequent proxies may be
given (and, if given, will not be deemed effective). Such designees of the
Purchaser will thereby be empowered, among other things, to exercise all voting
and other rights with respect to such Shares in respect of any annual, special
or adjourned meeting of the Company's stockholders, action by written consent of
stockholders, or otherwise, as they in their sole discretion deem proper.  The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, the Purchaser must be able to exercise full voting and other
rights with respect to such Shares, including voting at any meeting or action by
written consent of stockholders then scheduled, immediately after the
Purchaser's acceptance for payment of such Shares.

  Determination of Validity.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser in its sole discretion, whose determination
will be final and binding.  The Purchaser reserves the absolute right to reject
any or all tenders determined by it not to be in proper form or the acceptance
for payment of which, or payment for which, may, in the opinion of the
Purchaser's counsel, be unlawful.  The Purchaser also reserves the absolute
right to waive any of the conditions of the Offer (other than the Minimum
Condition, without the Company's consent) or any defect or irregularity in the
tender of any Shares, whether or not similar defects or irregularities are
waived in the case of other stockholders.  No tender of Shares will be deemed to
have been validly made until all defects and irregularities have been cured or

                                       6
<PAGE>
 
waived.  None of the Purchaser, the Parent, the Depositary, the Information
Agent or any other person will be under any duty to give notification of any
defects or irregularities in tenders, nor shall any of them incur any liability
for failure to give any such notification.  The Purchaser's interpretation of
the terms and conditions of the Offer (including the Letter of Transmittal and
instructions thereto) will be final and binding on all parties.

  It is a violation of Section 14(e) of the Exchange Act and Rule 14e-4
thereunder for a person to tender Shares for his own account unless the person
so tendering (i) owns such Shares or (ii) owns other securities convertible into
or exchangeable for such Shares or owns an option, warrant or right to purchase
such Shares and intends to acquire such Shares for tender by conversion,
exchange or exercise of such option, warrant or right.  Rule 14e-4 provides a
similar restriction applicable to the tender or guarantee of a tender on behalf
of another person.  The tender of Shares pursuant to one of the procedures
described above will constitute a binding agreement between the tendering
stockholder and the Purchaser, upon the terms and subject to the conditions of
the Offer, including the tendering stockholder's representation and warranty
that (i) such stockholder owns the Shares being tendered within the meaning of
Rule 14e-4 and (ii) the acceptance for payment by the Purchaser of such Shares
complies with Rule  14e-4.

  4.  WITHDRAWAL RIGHTS.  Tendered Shares may be withdrawn at any time prior to
the Expiration Date and, unless theretofore accepted for payment and paid for by
the Purchaser as provided in the Offer, may also be withdrawn after May 22,
1995.  Except for such withdrawal rights, tenders of Shares pursuant to the
Offer are irrevocable.

  To be effective, a written, telegraphic or facsimile transmission notice of
withdrawal must be timely received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase and must specify the name of
the person having tendered the Shares to be withdrawn, the number of Shares to
be withdrawn and the name of the registered holder of the Shares, if different
from the name of the person who tendered the Shares.  If certificates for Shares
have been delivered or otherwise identified to the Depositary, then, prior to
the physical release of such certificates, the serial numbers shown on such
certificates must be submitted and, unless such Shares have been tendered by an
Eligible Institution, the signatures on the notice of withdrawal must be
guaranteed by an Eligible Institution which is a member in good standing of the
Securities Transfer Agents Medallion Program.  If Shares have been delivered
pursuant to the procedures for book-entry transfer set forth in Section 3, any
notice of withdrawal must also specify the name and number of the account at the
appropriate Book-Entry Transfer Facility to be credited with the withdrawn
Shares and otherwise comply with such Book-Entry Transfer Facility's procedures.

  Withdrawals of tenders of Shares may not be rescinded, and any Shares properly
withdrawn will thereafter be deemed not validly tendered for purposes of the
Offer.  However, withdrawn Shares may be retendered by again following one of
the procedures described in Section 3 at any time prior to the Expiration Date.

  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser in its sole
discretion, whose determination will be final and binding on all parties.  None
of the Purchaser, the Parent, the Depositary, the Information Agent or any other
person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.

  5.  CERTAIN TAX CONSEQUENCES TO STOCKHOLDERS.  The receipt by non-dissenting
stockholders of cash for Shares pursuant to the Offer (or pursuant to the
Merger) will be treated as a taxable sale for federal income tax purposes and
may also be a taxable transaction under applicable state, local, foreign and
other tax laws.  In general, for federal income tax purposes, such a stockholder
will recognize gain or loss upon such sale equal to the difference between his
adjusted tax basis in the Shares sold in the Offer (or pursuant to the Merger)
and the amount of cash to be received in exchange therefor.  If a stockholder
owns blocks of Shares acquired at different prices, gain or loss will be
calculated separately for each block of Shares tendered and accepted for payment
pursuant to the Offer (or converted in the Merger). Such gain or loss generally
will be capital gain or loss for federal income tax purposes if the Shares were
held as capital assets.  Such capital gain or loss will be long-term capital
gain or loss with respect to Shares held more than 12 months.

                                       7
<PAGE>
 
  The foregoing discussion may not apply to Shares acquired by a stockholder
pursuant to an employee benefit plan or otherwise as compensation, to
stockholders who are not citizens or residents of the United States, or to other
categories of stockholders subject to special treatment under federal income tax
laws, such as dealers in securities, banks, insurance companies and tax-exempt
entities.

  In order to avoid backup withholding of federal income tax on the cash
received upon the surrender of Shares pursuant to the Offer, a holder of Shares
must, unless an exemption applies, provide the Depositary with his correct
taxpayer identification number ("TIN") on Substitute Form W-9 included in the
Letter of Transmittal and certify, under penalties of perjury, that such number
is correct.  If the correct TIN is not provided, a penalty may be imposed by the
Internal Revenue Service and payments made in exchange for the surrendered
Shares may be subject to backup withholding of 31%. Backup withholding is not an
additional federal income tax.  Rather, the federal income tax liability of
persons subject to backup withholding will be reduced by the amount of such tax
withheld.  If backup withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.

  THE FOREGOING SUMMARY OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER
AND THE MERGER IS INCLUDED FOR GENERAL INFORMATION ONLY.  DUE TO THE INDIVIDUAL
NATURE OF TAX CONSEQUENCES, EACH HOLDER OF SHARES, ESPECIALLY ONE WHO DISSENTS
FROM THE MERGER, IS STRONGLY URGED TO CONSULT HIS OWN TAX ADVISOR WITH RESPECT
TO THE SPECIFIC TAX CONSEQUENCES TO HIM OF THE OFFER AND THE MERGER, INCLUDING
THE APPLICATION AND EFFECTS OF APPLICABLE STATE, LOCAL, FOREIGN AND OTHER TAX
LAWS AND OF CHANGES IN THE TAX LAWS.

  6. PRICE RANGE OF THE SHARES; DIVIDENDS. The Shares are traded on the AMEX
under the symbol "RRT." The following table sets forth the high and low closing
sales prices of the Shares on the AMEX as reported by Dow Jones & Company, Inc.,
for the periods indicated:

         1995

         January 3 through March 22.......................  11-3/8     5

  On March 16, 1995, the last day of trading prior to the date of the public
announcement of the Merger Agreement, the reported closing price of the Shares
on the AMEX was $8-3/8.  On March 22, 1995, the last full day of trading prior
to the printing of this Offer to Purchase, the reported closing price of the
Shares on the AMEX was $11-1/4.  Stockholders are urged to obtain a current
market quotation for the Shares.

  The Company has not paid any cash dividends on the Shares since 1989 and has
informed the Purchaser that it has no present intention to do so.  The Company
has agreed under the Merger Agreement not to pay or declare any dividends on the
Shares prior to the termination of the Merger Agreement without the consent of
the Parent and the Purchaser.

                                       8

  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; AMEX LISTING; EXCHANGE
ACT REGISTRATION.  The purchase of Shares pursuant to the Offer would reduce the
number of holders of Shares and the number of Shares that might otherwise trade
publicly and, depending on the number of Shares so purchased, could adversely
affect the liquidity and market value of the remaining Shares.  If the Merger is
consummated, the Shares will not trade publicly and the Parent will be the sole
holder of the capital stock of the Company.

  The Purchaser considers it likely that the purchase of Shares pursuant to the
Offer will mean that the Shares will no longer meet the requirements for
continued listing on the AMEX.  According to the published guidelines of the
AMEX, the AMEX would consider delisting the Shares if, among other things, the
number of record holders of 100 Shares or more were reduced to less than 300,
the number of publicly held Shares (exclusive of holdings of officers,
directors, controlling stockholders or other family or concentrated holdings)
were less than 200,000 or the aggregate market value of the publicly held Shares
were less than $1,000,000.  The Purchaser has been advised by the Company that
as of March 13, 1995 there were approximately 408 record holders of Shares.  If,
as a result of the purchase of Shares pursuant to the Offer, the Shares no
longer meet the requirements of the AMEX for continued listing and/or trading
and such trading of the Shares on the AMEX is discontinued, the market for the
Shares could be adversely affected.

  In the event that the Shares were no longer listed or traded on the AMEX, it
is possible that the Shares would trade on another securities exchange or in the
over-the-counter market and that price quotations would be reported by such
exchange, through the National Association of Securities Dealers Automated
Quotation System ("NASDAQ"), or other sources.  Such trading and the
availability of such quotations would, however, depend upon the number of
shareholders and/or the aggregate market value of the Shares remaining at such
time, the interest in maintaining a market in the Shares on the part of
securities firms, the possible termination of registration of the Shares under
the Exchange Act as described below, and other factors.  The Purchaser cannot
predict whether the reduction in the number of Shares that might otherwise trade
publicly would have an adverse or beneficial effect on the market price for, or
marketability of, the Shares or whether it would cause future market prices to
be greater or less than the Offer price.

  The Shares are currently "margin securities" under the rules of the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board").  Among
other things, this has the effect of allowing brokers to extend credit on
collateral consisting of the Shares.  Depending upon factors such as the number
of record holders of the Shares and the number and market value of publicly held
Shares, following the purchase of Shares pursuant to the Offer, the Shares might
no longer constitute "margin securities" for purposes of the Federal Reserve
Board's margin regulations, in which event Shares could no longer be used as
collateral for margin loans made by brokers.

  The Shares are currently registered under the Exchange Act.  Such registration
of the Shares may be terminated upon application of the Company to the SEC if
the Shares are neither listed on a national securities exchange nor held by 300
or more holders of record.  The Purchaser and the Parent intend to seek to cause
the Company to apply for termination of registration of the Shares as soon after
consummation of the Offer as the requirements for termination are met, and to
take all permitted actions to make the Company eligible for such termination.
Immediately upon the filing of an application to terminate registration of the
Shares, the Company's obligations to file periodic reports with the SEC would be
suspended.  If registration of the Shares were terminated, the Company would no
longer be required to file such reports and certain provisions of the Exchange
Act, such as the short-swing profit recovery provisions of Section 16(b), the
requirement of furnishing a proxy statement or information statement pursuant to
Sections 14(a) and 14(c) in connection with stockholders' meetings or written
consents (including any meeting or consent that may be required to approve the
Merger) and the related requirement of furnishing an annual report to
stockholders, and the requirements of Rule 13e-3 under the Exchange Act with
respect to "going private" transactions, would no longer be applicable to the
Company.  Furthermore, "affiliates" of the Company and persons holding
"restricted securities" of the Company may be deprived of the ability to dispose
of such securities pursuant to Rule 144 under the Securities Act of 1933.  If
registration of the Shares under the Exchange Act were terminated, the Shares
would no longer be "margin securities" or be eligible for listing on the AMEX or
for NASDAQ reporting.

                                       9
<PAGE>
 
  If the Shares are not deregistered prior to the Merger, then the Shares will
be delisted from the AMEX and the registration of the Shares under the Exchange
Act would be terminated following the consummation of the Merger.  In addition,
if registration of the Shares under the Exchange Act were terminated, the Shares
would no longer be eligible for NASDAQ reporting.

  Certain 1995 Financial and Budget Information.  The Company does not as a
matter of course make public forecasts as to future performance or earnings.
 
  In connection with a meeting with representatives of the Parent on March 2,
1995, Andrew T. Dwyer, Chairman of the Company, provided the Parent with data
regarding the Company's unaudited results of operations for the month of January
1995, its current cash on hand and a summary of the Company's "best case" budget
for the year ending December 31, 1995.  The January results showed revenues of
$4,225,000, pre-tax income of $296,000 and net income of $281,000.  Budgeted for
1995 were revenues of $60,752,000, pre-tax income of $2,815,000 and net income
of $2,635,000.  Material assumptions underlying the "best case" budget related 
by representatives of the Company to representatives of the Parent at the March 
2, 1995, meeting were that commodity prices would remain at relatively high 
levels and that the Company's major pending design and construction projects
would not be delayed.  Mr. Dwyer noted, however, that the budgeted numbers did
not include a gain in excess of $700,000 on the sale of the Company's glass
processing business in February 1995, or significantly increased prices
reflected in the January 1995 results.  He also noted that the Company's current
cash on hand exceeded $3,000,000.

  These budget amounts were not prepared with a view to public disclosure or
compliance with published guidelines of the Commission or the guidelines
established by the American Institute of Certified Public Accountants regarding
projections.  The Parent and the Purchaser did not rely on these budget amounts,
and they are included in the Offer to Purchase only because such information was
made available to the Parent and the Purchaser.  None of the Parent, the
Purchaser, or the Company assumes any responsibility for the accuracy of such
budget amounts.  In addition, because the estimates and assumptions underlying
these budget amounts are inherently subject to significant economic and
competitive uncertainties and contingencies, which are beyond the Parent's and
the Company's control, there can be no assurance that the budget amounts will be
realized.  These budget amounts are not to be viewed as facts; actual results
may be significantly higher or lower than those budgeted.  The budget amounts do
not give effect to the purchase of the Shares pursuant to the Offer or to the
Merger.

  The Company is subject to the informational filing requirements of the
Exchange Act and, in accordance therewith, is obligated to file reports and
other information with the SEC relating to its business, financial condition and
other matters.  Information as of particular dates concerning the Company's
directors and officers, their remuneration, options granted to them, the
principal holders of the Company's securities and any material interest of such
persons in transactions with the Company is required to be disclosed in proxy
statements distributed to the Company's stockholders and filed with the SEC.
Such reports, proxy statements and other information should be available for
inspection at the public reference facilities of the SEC at 450 Fifth Street,
N.W., Washington, D.C.  20549, and at the following regional offices of the SEC:
New York Regional Office, Seven World Trade Center, 13th Floor, New York, New
York 10048; and Chicago Regional Office, Citicorp Center, 500 West Madison
Street, Suite 1400, Chicago, Illinois 60661.  Copies may be obtained by mail,
upon payment of the SEC's customary charges, by writing to the SEC's principal
office at 450 Fifth Street, N.W., Washington, D.C.  20549.  Such material should
also be available for inspection at the offices of the AMEX, 86 Trinity Place,
New York, New York   10006.

  Except as otherwise stated in this Offer to Purchase, the information
concerning the Company contained herein has been taken from, or based upon,
publicly available documents on file with the SEC and other publicly available
information.  Although neither the Purchaser nor the Parent has any knowledge
that any such information is untrue, neither the Purchaser nor the Parent takes
any responsibility for the accuracy or completeness of such information or of
any other information concerning the Company prepared by the Company, or for any
failure by the Company to disclose events that may have occurred and may affect
the significance or accuracy of any such information.

  9. CERTAIN INFORMATION CONCERNING THE PURCHASER AND THE PARENT.  The Purchaser
is a Delaware corporation and a wholly owned subsidiary of the Parent formed to
effectuate the Merger.   The Parent is an Illinois corporation and a leading
provider of integrated solid waste management services in North America to
commercial, industrial, municipal and residential customers, as well as to other
waste management companies.  These services consist of solid waste collection,
transfer, resource recovery and disposal services.  As part of these services,
the Parent is engaged in providing, through its Recycle America(R) and Recycle
Canada(R) programs, paper, glass, plastic and metal recycling services to
commercial and industrial operations and curbside collection of such materials
from 

                                       12
<PAGE>
 
residences; in removing methane gas from sanitary landfill facilities for
use in electricity generation; and in providing medical and infectious waste
management services to hospitals and other health care and related facilities.
In addition, the Parent provides street sweeping and parking lot cleaning
services, and Port-O-Let(R) portable sanitation services to municipalities and
commercial and special event customers.  The Parent is a wholly-owned subsidiary
of WMX Technologies, Inc. ("WMX"), a Delaware corporation. The principal
business address and location of the principal executive officers of each of the
Purchaser, the Parent and WMX is 3003 Butterfield Road, Oak Brook, Illinois
60521.

  WMX, through its subsidiaries, is a leading international provider of
environmental, engineering and construction, industrial and related services.

  The Purchaser, Parent and WMX are collectively referred to herein as the
"Purchaser Entities."  The name, citizenship, business address, present
principal occupation or employment and five-year employment history of each of
the directors and executive officers of the Purchaser Entities are set forth in
Schedule I hereto.

  Until immediately prior to the time the Purchaser purchases Shares pursuant to
the Offer, it is not anticipated that the Purchaser will have any significant
assets or liabilities or engage in activities other than those incident to its
formation and capitalization and the transactions contemplated by the Offer and
the Merger.  Because the Purchaser is a newly formed corporation and has minimal
assets and capitalization, no meaningful financial information regarding the
Purchaser is available.

  WMX is subject to the informational filing requirements of the Exchange Act
and, in accordance therewith, is obligated to file reports and other information
with the SEC relating to its business, financial condition and other matters.
Information, as of particular dates, concerning WMX's directors and officers,
their remuneration, options granted to them, the principal holders of WMX's
securities and any material interest of such persons in transactions with WMX is
required to be described in proxy statements distributed to WMX's stockholders
and filed with the SEC.  Such reports, proxy statements and other information
filed with the SEC are available for inspection and copies may be obtained in
the same manner as set forth for the Company in Section 8.  The common stock of
WMX is listed on the New York Stock Exchange ("NYSE"), and such information is
also available for inspection at the offices of the NYSE, 20 Broad Street, New
York, New York  10005.

  Set forth below is a summary of certain consolidated financial information
with respect to WMX and its subsidiaries excerpted or derived from the
information contained in the Annual Report of WMX on Form 10-K for the year
ended December 31, 1993 and the audited financial statements of WMX for the year
ended December 31, 1994. More comprehensive financial information is included in
such report and such financial statements (which will be included in the Annual
Report of WMX on Form 10-K for the year ended December 31, 1994, which WMX
expects to file with the SEC on or prior to March 31, 1995), and other documents
filed by WMX with the SEC, and the financial information summary set forth below
is qualified in its entirety by reference to such reports and all the financial
information and related notes contained therein.

  On March 17, 1995, WMX announced that its Chemical Waste Management, Inc.
wholly owned subsidiary would record a special after-tax charge of approximately
$91 million, or $0.19 per WMX share, in the first quarter of 1995 primarily
related to a revaluation of investments in certain hazardous waste treatment and
processing technologies and facilities.

  None of the Purchaser or, to the best knowledge of any of the Purchaser
Entities, any person listed on Schedule I or any of the other Purchaser Entities
beneficially owns or has a right to acquire any Shares.  None of the Purchaser,
the Parent or, to the best knowledge of the Purchaser and the Parent, any of the
persons or entities referred to above, or any of the respective executive
officers, directors or subsidiaries of any of the foregoing which beneficially
owns or has a right to acquire any Shares, has effected any transactions in
Shares during the past 60 days.

  Except as set forth in this Offer to Purchase, none of the Purchaser Entities,
or, to the best knowledge of any of the Purchaser Entities, any of the persons
listed on Schedule I, has any contract, arrangement, understanding or
relationship with any other person with respect to any securities of the
Company, including, but not limited to, any contract, arrangement, understanding
or relationship concerning the transfer or the voting of any securities of the
Company, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.  None
of the Purchaser Entities, or, to the best knowledge of any of the Purchaser
Entities, any of the persons listed on Schedule I, has had any business
relationships or transactions with the Company or any of its executive officers,
directors or affiliates that would require disclosure herein under the rules of
the SEC.  Except as set forth in this Offer to Purchase, there have been no
contacts, negotiations or transactions between the Purchaser Entities, or their
respective subsidiaries or, to the best knowledge of any of the Purchaser
Entities, any of the persons listed on Schedule I, and the Company or its
affiliates concerning a merger, consolidation or acquisition, tender offer or
other acquisition of securities, election of directors or a sale or other
transfer of a material amount of assets that would require disclosure herein
under the rules of the SEC.  In late 1992, Wheelabrator Technologies Inc.
("WTI"), a 56%-owned subsidiary of WMX, acquired for cash the capital stock of
two subsidiaries of JWP, Inc. ("JWP"), which was then the owner of approximately
34.7% of the outstanding common stock of the Company and of which Andrew T.
Dwyer, Chairman of the Company, was Chairman of the Board and Chief Executive
Officer.  The subsidiaries were engaged in the design, engineering and
installation of systems for the capture and elimination of volatile organic
compound emissions.  In a separate, but related, transaction WTI acquired
substantially all of the biosolids handling and treatment businesses conducted
by another JWP subsidiary.  Revenues of the businesses acquired in the year
prior to their acquisition aggregated approximately $47 million. None of these
transactions involved the Company.

  10.  BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY; CERTAIN EMPLOYMENT
ARRANGEMENTS.  In late spring 1994, Andrew T. Dwyer, Chairman of the Board of
the Company, contacted Phillip B. Rooney, President of the Parent, to discuss
potential synergies which might be realized if the Company's technology and
experience in designing, constructing and operating material recycling
facilities could be combined with the Parent's operating and capital resources,
either through a joint venture or by jointly pursuing certain project
opportunities.  This discussion led to a meeting on June 1, 1994 between Mr.
Dwyer, Mr. Rooney and Joseph M. Holsten, Chief Financial Officer of the Parent,
at which these possible synergies were further explored.  At this meeting, Mr.
Rooney also expressed an interest in having the Parent acquire the Company,
indicating that on the basis of a preliminary valuation analysis of publicly
available information regarding the Company which the Parent had performed, the
Parent might be willing to consider paying a price of $7.50 per Share in such an
acquisition.  Noting the recent improvement in the Company's financial
performance, Mr. Dwyer declined to discuss a possible acquisition of the Company
at that price.  He did, however, suggest that a price of at least $10.00 per
Share might be of interest to him personally.  The Parent's representatives
indicated their view that such a higher price was not warranted and the
discussion of a possible acquisition terminated.

  In October 1994, the Company and the Parent entered into a confidentiality
agreement and William A. Rodgers, Jr., then Vice President - Business
Development of the Parent's Mid-Atlantic Group, Anthony Farina, President of the
Parent's Northeast Group, and Daniel J. Kemna, Manager - Recycling of the
Parent, toured the Company's Ocean County, New Jersey material recovery
facility.  During this site visit, portions of which were also attended by Mr.
Dwyer, Lawrence J. Schorr, President of the Company, and the Company's facility
manager, the possibility of 

                                       15

<PAGE>

the Company's being retained by the Parent to render technical advisory services
with regard to the Parent's material recovery facility operations was raised by
the Parent's representatives. Mr. Rodgers also broached the subject of a
possible acquisition of the Company by the Parent, but Mr. Dwyer indicated that
there was no interest from his standpoint in discussing such a transaction at
that time.
 
  On January 24, 1995, the Company released its financial results for the year 
ended December 31, 1994.  Subsequently, Mr. Rooney contacted Mr. Dwyer's office
and Paul A. Gould, a director of the Company and a Managing Director of Allen &
Company Incorporated ("Allen & Co."), and arranged for a meeting on March 2,
1995, for the principal purpose of discussing a possible acquisition of the
Company by the Parent or considering another form of business combination
between them.  Mr. Dwyer furnished the Parent's representatives with information
regarding the Company's results of operations and financial position as of and
for the month ended January 31, 1995, as well as the Company's "best case" 1995
operating budget.  He also provided the Parent's representatives with an
estimate of the Company's then current cash position.  See "Certain 1995
Financial and Budget Information" in Section 8. The March 2 meeting was attended
by Messrs. Rooney, Holsten and Rodgers, from Parent, and by Messrs. Dwyer and
Gould.

  At the March 2 meeting, a discussion occurred regarding the Company's
management and its ongoing projects, and the assumptions underlying the
Company's 1995 operating budget were reviewed.  The Parent's representatives
proposed an acquisition of the Company by the Parent on the basis of a cash
price of $10.00 per Share.  Having initially during the meeting expressed an
interest in receiving $14.00 per Share in cash, Mr. Dwyer subsequently indicated
that a price of $12.00 per Share in cash would be acceptable.  After further 
negotiations among the participants in the meeting, it was generally agreed
that, subject to approval of the Company's Board of Directors, the Parent would
offer to acquire all of the Company's outstanding shares for a cash price of
$11.50 per Share, and Messrs.  Dwyer and Gould and Allen & Co. would tender
their Company shares to the Parent in such offer, subject to the Parent's
completion of due diligence and to negotiation and execution of a definitive
acquisition agreement containing typical terms and conditions.

  During the next two weeks, representatives of the Parent conducted a legal,
financial, environmental and operational review of the Company, and
representatives of the Parent and the Company (including outside counsel for all
parties) negotiated the terms of the Merger Agreement and the separate
agreements pursuant to which Messrs.  Dwyer and Gould and Allen & Co. are to
tender Shares owned by them to the Parent pursuant to the Offer (the "Stock
Tender Agreements").  See "Stock Tender Agreements" in Section 11.  On March 17,
1995, the Boards of Directors of the Parent, the Purchaser and the Company
unanimously approved the Merger Agreement and it was executed by all parties,
followed by execution of the Stock Tender Agreements by the parties thereto.

  Certain Employment Arrangements.  The Purchaser has agreed with Lawrence J.
Schorr, chief executive officer of the Company that Mr. Schorr will be employed
by the Company for a period of two years after the Merger, and thereafter on an
at-will basis, for an annual salary of $280,000, with options on WMX common
stock to be granted for 1995 and 1996 with a value equal to 100% of base salary
(prorated for 1995).  The Purchaser expects to discuss arrangements with several
other key employees of the Company providing for the continued employment of
such employees at or near their current levels of compensation.

  In addition, the Purchaser expects to propose an extension by the Company of
the consulting agreement between Mr. Dwyer and the Company, for a period of one
year after the Merger, at its current annual rate of $100,000.

  11.  PURPOSE OF THE OFFER; PLANS OR PROPOSALS OF THE PURCHASER; THE MERGER
AGREEMENT; THE STOCK TENDER AGREEMENTS.  The purpose of the Offer is to acquire
control of, and a majority equity interest in, the Company as a step toward the
acquisition by the Parent of the entire equity interest in the Company.  The
Parent currently intends, as soon as practicable after consummation of the
Offer, to obtain majority representation on the Company's Board of Directors and
to consummate the Merger.  The Merger Agreement provides for such majority
representation on the Board of Directors, subject to compliance with Section
14(f) of the Exchange Act.

                                       16

<PAGE>
 
  If the Parent obtains control of the Company pursuant to the Offer or
otherwise, it expects to conduct a detailed review of the Company, its business,
assets, corporate structure, capitalization, operations, properties, policies,
management and personnel and to consider to what extent changes would be
desirable in light of the circumstances that then exist. Although significant
changes in the structure and business of the Company are not currently
contemplated, the Parent reserves the right to make such changes in the future,
which may include combining the assets and business of the Company with
operations of the Parent and other corporate affiliates of the Parent.

MERGER AGREEMENT

  Effect of the Merger.  The Merger Agreement provides that, subject to the
terms and conditions thereof, as soon as practicable following the expiration of
the Offer, the Purchaser will be merged into the Company, which will continue as
the surviving corporation (the "Surviving Corporation"). Each then outstanding
Share, other than Shares (i) owned by the Purchaser or the Parent or any of
their corporate affiliates, (ii) held in the treasury of the Company or (iii)
owned by stockholders who have perfected dissenters' rights will, by virtue of
the Merger and without any action on the part of the holder thereof, be
converted into and represent the right to receive, and shall be exchangeable
for, the Merger Consideration.  In the Merger, each then outstanding Share owned
by the Purchaser, the Parent or any of their corporate affiliates or held in the
treasury of the Company will be canceled without payment of any consideration
therefor and without any conversion thereof.  Each outstanding share of common
stock of the Purchaser will be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation.  See
"Appraisal Rights" in this Section 11 for a discussion of the rights of
dissenters.

  Upon the consummation of the Merger, the separate existence of the Purchaser
will cease and the separate corporate existence of the Company as a corporation
organized under the DGCL will continue unaffected by the Merger.  The Company's
certificate of incorporation in effect immediately prior to the time the Merger
becomes effective under the DGCL (the "Effective Time"), as amended to change
the total authorized capital stock of the Surviving Corporation to 1,000 shares
of common stock, par value $1.00 per share, will be the certificate of
incorporation of the Surviving Corporation from and after the Effective Time.
The Purchaser's by-laws in effect immediately prior to the Effective Time will
be the by-laws of the Surviving Corporation until thereafter amended as provided
in such by-laws or by law.  The directors of the Purchaser and the officers of
the Company immediately prior to the Effective Time will be the directors and
officers, respectively, of the Surviving Corporation, each to hold office,
subject to the provisions of the certificate of incorporation and by-laws of the
Surviving Corporation, until their respective successors have been duly elected
or appointed.

  Directorships.  The Merger Agreement provides that, upon the Purchaser's
acquisition of 50.1% or more of the outstanding Shares pursuant to the Offer or
otherwise, and from time to time thereafter, the Purchaser and the Parent will
be entitled, subject to compliance with applicable law, to designate such number
of the members of the Company's Board of Directors, rounded up to the next whole
number (but in no event more than one less than the total number of directors on
the Company's Board of Directors), that will give the Parent and the Purchaser,
subject to compliance with Section 14(f) of the Exchange Act, representation on
the Board of Directors equal to the product of the number of directors on the
Board of Directors and the percentage that such number of Shares so purchased
bears to the number of Shares outstanding.  The Merger Agreement also provides
that the Company will, upon the request of the Parent and the Purchaser,
promptly increase the size of its Board of Directors or use all reasonable
efforts to secure the resignations of such number of directors as is necessary
to enable the Parent's and the Purchaser's designees to be elected to the
Company's Board of Directors, and will use all reasonable efforts to cause such
designees to be so elected, subject in all cases to Section 14(f) of the
Exchange Act.  From and after the date that such designees to the Company's
Board of Directors constitute a majority of the Board of Directors of the
Company, any action taken by the Company to amend or terminate the Merger
Agreement or to waive any conditions to the performance of the Company's
obligations under the Merger Agreement will require the approval of a majority
of the members of the Board of Directors, if any, who are not designees or
affiliates of the Parent or the Purchaser. The Parent currently intends to
designate to the Company's Board of Directors after consummation of the Offer
only persons listed as executive officers of Parent, Purchaser or WMX on
Schedule I.

                                       17

  Representations and Warranties.  The Merger Agreement contains representations
and warranties by the Company regarding, among other things, its capitalization,
authority relative to the Merger Agreement, its filings with the SEC,
information supplied in connection with the Offer, its business, financial
condition, assets and liabilities and the absence of certain changes in its
business.  The Merger Agreement contains representations and warranties by the
Parent and the Purchaser regarding, among other things, their authority relative
to the Merger Agreement and the availability to them of sufficient funds to
effectuate the Offer.

  Conduct of Business.  Pursuant to the Merger Agreement, the Company has agreed
that, among other things, during the period from the date of the Merger
Agreement until the Effective Time (except as expressly contemplated by the
Merger Agreement, including any disclosures contemplated by Annex B of the
Merger Agreement, or to the extent that the Parent and the Purchaser shall
otherwise consent in writing) (i) the Company will carry on its business in the
usual, regular and ordinary course in substantially the same manner as
heretofore conducted; (ii) the Company will not and will not propose to (a)
declare or pay any dividend on, or make other distributions in respect of, any
of its capital stock (other than any regular dividends on its preferred stock),
(b) split, combine or reclassify any of its capital stock or issue, authorize or
propose the issuance of any other securities in respect of, in lieu of or in

will not sell, issue or authorize or propose the sale or issuance of, or

any such shares or other convertible securities (other than the issuance of
Shares upon the exercise or conversion of outstanding stock options, warrants or
convertible securities); (iv) the Company will not amend its certificate of
incorporation or by-laws; and (v) the Company will not (a) acquire or agree to
acquire by merging or consolidating with, or by purchasing a substantial portion
of the assets or securities of, or by any other manner, any business or any
corporation, partnership, association or other business organization or division
thereof or otherwise acquire or agree to acquire any assets that are material,
individually or in the aggregate, to the Company, (b) sell, lease or otherwise
dispose of, or agree to sell, lease or otherwise dispose of, any of its assets
that are material, individually or in the aggregate, to the Company, except in
the ordinary course of business consistent with prior practice, (c) incur any
indebtedness for borrowed money or guarantee any such indebtedness, or issue or
sell any debt securities of the Company or guarantee any debt securities of
others, other than in the ordinary course of business consistent with prior
practice, (d) adopt or amend in any material respect any collective bargaining
agreement or employee benefit plan other than in the ordinary course of business
consistent with prior practice, or (e) grant to any executive officer any
increase in compensation or in severance or termination pay, or enter into any
employment agreement with any executive officer, except as may be required under
employment or termination agreements in effect on the date of the Merger
Agreement or in the ordinary course of business consistent with prior practice.

  The Merger Agreement further provides that, if a vote of stockholders of the
Company is legally required to authorize the Merger, the Parent and the
Purchaser will vote all the Shares owned or acquired by them in favor of the
Merger.

  Conditions to the Merger.  The respective obligations of each of the Company,
the Purchaser and the Parent to effect the Merger are subject to the
satisfaction or waiver at or prior to the Effective Time of each of the
following conditions:  (i) if required by the DGCL, the Merger Agreement shall
have been approved and adopted by the requisite affirmative vote of the
stockholders of the Company in accordance with the DGCL; (ii) no statute, rule,
regulation, executive order, decree, injunction or restraining order shall have
been enacted, entered, promulgated or enforced by any court of competent
jurisdiction or governmental authority that prohibits or restricts the
consummation of the Merger; and (iii) any waiting period applicable to the
Merger under the HSR Act will have expired or been terminated.  The obligations
of the Purchaser and the Parent to consummate the Merger are also subject to the
satisfaction, at or prior to the Effective Time, of the condition that the
Purchaser will have accepted for payment and paid for Shares tendered pursuant
to the Offer; this condition will be deemed satisfied, however, if the Purchaser
fails to accept for payment and pay for Shares pursuant to the Offer in
violation of the terms of the Offer.


                                      18

<PAGE>
 
  Stock Options, Warrants and Convertible Securities.  The Merger Agreement
provides that at or prior to the consummation of the Offer, the Company will
make arrangements the effect of which shall be that no shares of capital stock
of the Surviving Corporation will be issuable after the Effective Time pursuant
to options, warrants or convertible securities to acquire shares and, (i) in
full settlement thereof, each holder of an option or warrant will receive or be
entitled to receive promptly after the Effective Time a cash payment from the
Company in an amount equal to the excess, if any, of the price paid for each
Share pursuant to the Merger over the per Share exercise price of such stock
option or warrant, multiplied by the number of Shares covered by such stock
option or warrant, net of any income tax withholding and payroll taxes
applicable to such payment, and (ii) all outstanding 8.25% convertible
redeemable preferred stock of the Company will be redeemed by the Company or
converted to Shares prior to the consummation of to the Offer.

  Stockholder Approval.  If the Purchaser, or any other direct or indirect
subsidiary of the Parent, acquires at least 90% of the outstanding Shares
pursuant to the Offer, or otherwise, the Purchaser would, under the DGCL, be
able to effect the Merger without any prior notice to, or vote by, the Company's
stockholders.  If fewer than 90% of the outstanding Shares are acquired by the
Purchaser, the Merger would be subject to approval by the holders of a majority
of outstanding Shares under the DGCL.  Accordingly, if the number of Shares
acquired by the Purchaser constitutes a majority of the outstanding Shares, the
Purchaser will be able to effect the Merger without the affirmative vote of any
other holder of Shares.  Holders of approximately 33% of the outstanding Shares
(on a fully diluted basis) have agreed to tender the Shares beneficially owned
by them pursuant to the Offer.  See "Stock Tender Agreements" below in this
Section 11.

  Appraisal Rights.  No appraisal rights are available in connection with the
Offer.  However, if the Merger is consummated, stockholders of the Company may
have certain rights under Delaware law to dissent and demand appraisal of, and
payment in cash of the fair value of, their Shares.  Such rights, if the
statutory procedures were complied with, could lead to a judicial determination
of the fair value (excluding any element of value arising from the
accomplishment or expectation of the Merger) required to be paid in cash to such
dissenting holders for their Shares.  Any such judicial determination of the
fair value of Shares could be based upon considerations other than or in
addition to the price paid in the Offer and the market value of the Shares,
including asset values and the investment value of the Shares.  The value so
determined could be more or less than the purchase price per Share pursuant to
the Offer or the consideration per Share to be paid in the Merger.

  In addition, several decisions by Delaware courts have held that, in certain
instances, a controlling stockholder of a corporation involved in a merger has a
fiduciary duty to the other stockholders that requires the merger to be fair to
such other stockholders.  In determining whether a merger is fair to minority
stockholders, the Delaware courts have considered, among other things, the type
and amount of consideration to be received by the stockholders and whether there
were fair dealings among the parties.  The Delaware Supreme Court has indicated
in recent decisions that in most cases the remedy available in a merger that is
found not to be "fair" to minority stockholders is the right to appraisal
described above or a damages remedy based on essentially the same principles.

  Proposals by Third Parties.  Pursuant to the Merger Agreement, the Company has
agreed that it shall not, and shall use all reasonable efforts to cause its
affiliates, officers, directors, employees, representatives and agents not to,
directly or indirectly, solicit, initiate or knowingly promote discussions or
negotiations with, any corporation, partnership, person or other entity or group
(other than the Parent or any of its affiliates or representatives) concerning
any merger, tender offer, sale of any material assets, sale of shares of capital
stock or similar transaction involving the Company or any division of the
Company.  Notwithstanding the foregoing, the Company may, if required by the
fiduciary duties of the directors after consulting with outside counsel to the
Company, (i) furnish information to any corporation, partnership, person or
other entity or group pursuant to appropriate confidentiality agreements, and
(ii) negotiate or participate in discussions with such entity or group.  The
Company shall immediately advise the Parent of the terms of any proposal, the
fact of any negotiation, discussion or inquiry and the identity of the party
making such proposal or inquiry or involved in such discussion or negotiation. 
See "Certain Fee" below for information regarding a fee that might become
payable by the Company to the Purchaser as a result of such other transactions.


                                      19

<PAGE>
 
  Certain Fee.  If at any time while the Merger Agreement is in effect (i) any
person, corporation, partnership or other entity (other than the Parent, the
Purchaser or any of their affiliates) (a "Third Person") acquires more than 33%
of the outstanding Shares, (ii) a Third Person acquires more than 50% of the
Company's total assets, (iii) the Company consummates a plan of liquidation
relating to more than 50% of its total assets, (iv) the Company repurchases more
than 50% of the outstanding Shares, (v) the Company consummates a merger of the
Company with, the sale of all or substantially all of the assets of the Company
to, or any other business combination involving the Company with, a Third
Person, or (vi) Parent and the Purchaser terminate the Merger Agreement because
of the failure to satisfy the Minimum Condition and within one year from the
date of such termination a transaction contemplated by the preceding clauses
(i), (ii) or (v) is consummated with a Third Person, provided (1) that such
transaction is accomplished so as to provide a yield to holders of Shares of at
least the equivalent of $11.50 per Share and (2) there was a public announcement
or written proposal to effect such transaction by or with such Third Person
while the Merger Agreement was in effect, or (vii) the Board of Directors of the
Company withdraws or amends in any material respect its recommendation that the
Offer be accepted by the Company's stockholders and that stockholders tender
their Shares in the Offer, unless such withdrawal or amendment results from a
material breach by the Parent or the Purchaser of any representations or
warranties in the Merger Agreement or a failure by the Parent or the Purchaser
to fulfill any material covenant in the Merger Agreement, then the Company
shall, within five days after the first of such events has occurred, pay the
Parent a fee of $1,000,000.

  Certain Amendments.  The Merger Agreement further provides that, whether
before or after the vote of the holders of Shares contemplated thereby, the
Merger Agreement may be amended by written agreement of the Company, the Parent
and the Purchaser; however, after the approval of the Merger Agreement by the
holders of Shares, no such amendment shall reduce or change the Merger
Consideration to be delivered to the holders of Shares or shall otherwise
adversely affect the rights under the Merger Agreement of the holders of Shares
without their approval.

  Indemnification.  The Merger Agreement provides that the Parent acknowledges
that all rights to indemnification or limitations on liability currently
existing in favor of the present or former employees, agents, directors or
officers of the Company as provided in its certification of incorporation, by-
laws, agreements or pursuant to applicable law in effect on the date of the
Merger Agreement shall survive the Merger and shall continue in full force and
effect for a period of not less than the applicable statutes of limitations;
however, in the event any claim or claims are asserted or made within such
applicable period, all rights to indemnification in respect of such claim or
claims shall continue until disposition of any and all such claims.  If any
action, suit, proceeding or other investigation relating to the Merger Agreement
or to the transactions contemplated thereby is commenced, whether before or
after the Merger becomes effective, the parties shall cooperate with each other
and use all reasonable efforts to defend against and respond to any such action,
suit, proceeding or investigation.

  The Merger Agreement also provides that the Purchaser and the Parent will
maintain in effect the Company's current directors' and officers' insurance
policy for the remainder of its term and purchase a policy providing continued
coverage relating to actions, alleged actions, omissions and alleged omissions
occurring at or prior to the time of the Merger for a period of at least three
years from and thereafter, provided that the total amount the Parent and the
Purchaser are required to expend for such coverage shall not exceed 250% of the
1994 premium for such current policy.

  Termination.  The Merger Agreement may be terminated and the Merger abandoned
at any time prior to the Effective Time, whether before or after stockholder
approval of the Merger:

     (i)  by mutual written consent of the Boards of Directors of the Company,
     the Parent and the Purchaser;

     (ii)  by any of the Company, the Parent or the Purchaser:

          (a)  if a purchase of Shares pursuant to the Offer shall not have
          occurred on or before June 30, 1995; provided, however, that the right
          to terminate the Merger Agreement for such reason will not be
          available to any party whose failure to fulfill any obligation under

                                      20

<PAGE>
 
          the Merger Agreement has been the cause of, or resulted in, the
          failure of such purchase to occur on or before such date; or

          (b)  if any court of competent jurisdiction, or any governmental body,
          or regulatory or administrative agency or commission having
          appropriate jurisdiction has issued an order, decree or ruling or
          taken any other action restraining, enjoining or otherwise prohibiting
          the transactions contemplated by the Merger Agreement and such order,
          decree, ruling or other action shall have become final and non-
          appealable;

     (iii) by the Company:

          (a)  if the Purchaser has (1) failed to commence the Offer within five
          business days following public announcement of the Merger Agreement,
          (2) terminated the Offer or (3) failed to pay (by deposit with the
          Depositary for the Offer) for Shares pursuant to the Offer within five
          business days following the Expiration Date; or

          (b)  if, prior to the purchase of Shares pursuant to the Offer, the
          Board of Directors of the Company has (1) withdrawn (or modified in a
          manner adverse to the Purchaser) its recommendation to the holders of
          Shares to accept the Offer in order to permit the Company, in response
          to an offer from a Third Person as to which the Company has not
          contravened its obligations with respect thereto (as described above
          in this Section 11 under "Proposals by Third Parties"), to execute a
          definitive agreement providing for the acquisition of the Company, or
          to approve a tender offer for all of the outstanding Shares, in either
          case on terms determined by the Company's Board of Directors after
          consultation with outside legal and financial advisors, to be more
          favorable to the holders of Shares than the acquisition of the Company
          contemplated by the Merger Agreement, or (2) recommended another such
          offer; or

     (iv)  by the Parent and the Purchaser:

          (a)  if due to an occurrence that would result in a failure to satisfy
          any of the conditions set forth in Section 13, the Purchaser shall
          have (1) failed to commence the Offer within five business days
          following the date of the Merger Agreement or (2) terminated the
          Offer; or

          (b)  if, prior to the purchase of Shares pursuant to the Offer, the
          Board of Directors of the Company shall have withdrawn (or modified in
          a manner adverse to the Purchaser) its approval or recommendation of
          the Offer, the Merger Agreement or the Merger, or shall have
          recommended another offer; or

          (c)  if the Company deliberately fails to perform in any material
          respect any of its obligations under the Merger Agreement, and, at the
          time of such failure, the Parent's and the Purchaser's designees on
          the Board of Directors of the Company do not constitute a majority of
          the members of the Board of Directors of the Company.

STOCK TENDER AGREEMENTS

  After the execution of the Merger Agreement, the Purchaser and the following
stockholders of the Company entered into the Stock Tender Agreements: Allen &
Co., Paul A. Gould and Andrew T. Dwyer.  Pursuant to such Agreements, so long 
as the Board of Directors of the Company has not withdrawn its recommendation 
of the Offer in accordance with the Merger Agreement, those stockholders will
validly tender (and not thereafter withdraw) the Shares beneficially owned by
each of them pursuant to and in accordance with the terms of the Offer.  As of
March 17, 1995, the stockholders (with members of their families) beneficially
owned a total of 1,082,506 Shares, representing approximately 33% of the then
outstanding Shares, on a fully diluted basis.

                                      21

<PAGE>
 
  In connection with the Stock Tender Agreements, the parties thereto have made
certain customary representations, warranties and covenants, including with
respect to (i) ownership of the Shares, (ii) their authority to enter into and
perform their obligations under the Stock Tender Agreements, (iii) the ability
of the parties to enter into the Stock Tender Agreements without violating other
agreements to which they are party, (iv) the absence of liens and encumbrances
on and in respect of the stockholder parties' Shares and (v) restrictions on the
transfer of the stockholder parties' Shares.

  12.  SOURCE AND AMOUNT OF FUNDS.  If all the Shares outstanding or issuable
upon exercise of rights to acquire Shares on March 17, 1995 are purchased
pursuant to the Offer, the amount required by the Purchaser to purchase such
Shares and to pay related fees and expenses will be approximately $38,000,000,
which amount will be furnished to the Purchaser by the Parent.  The Parent is
expected to obtain such funds from its general corporate funds.

  13.  CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other provisions of
the Offer, the Purchaser will not be required to accept for payment or, subject
to any applicable rules and regulations of the SEC, including Rule 14e-1(c)
(relating to the Purchaser's obligation to pay for or return tendered Shares
promptly after termination of the Offer), pay for, and may delay the acceptance
for payment, or the payment of, any tendered Shares not theretofore accepted for
payment or paid for, and may terminate or amend the Offer as provided in Section
11 hereof, if the Minimum Condition has not been satisfied or if, at any time on
or after the date of the Merger Agreement and at or before the time of payment
for any such Shares (whether or not any Shares have been accepted for payment or
paid for pursuant to the Offer), any of the following events have occurred:

          (i)  there shall have occurred or been threatened any event which
     could reasonably be expected to have any adverse effect on the business,
     financial condition or results of operations of the Company and its
     subsidiaries which is material to the Company and its subsidiaries taken as
     a whole, excluding any change which generally affects the recycling
     industry as a whole in the United States (such as changes in commodity
     prices and changes in legal requirements) (a "Material Adverse Effect"); or

          (ii)  there shall have occurred (a) any general suspension of trading
     in, or limitation on prices for, securities on the NYSE or the AMEX
     (excluding any coordinated trading halt triggered solely as a result of a
     specified decrease in a market index), (b) a declaration of a banking
     moratorium or any suspension of payments in respect of banks in the United
     States (whether or not mandatory), (c) any material limitation (whether or
     not mandatory) imposed by any governmental authority on the extension of
     credit by banks or other lending institutions in the United States that
     materially and adversely affects the ability of the Parent and the
     Purchaser to obtain extensions of credit, or (d) from the date of the
     Merger Agreement through the date of termination or expiration of the
     Offer, a decline of at least 33% in either the Dow Jones Average of
     Industrial Stocks or the Standard & Poor's 500 Index; or

          (iii)  (a) any of the representations and warranties made by the
     Company in the Merger Agreement shall not be true and correct in any
     material respect or (b) the Company shall have breached in any material
     respect any covenant contained in the Merger Agreement or the Merger
     Agreement shall have been terminated in accordance with its terms; or

          (iv)  there shall have been any action taken, or any statute, rule,
     regulation, judgment, order or injunction promulgated, enacted, entered or
     enforced, by any state, federal or foreign government or governmental
     authority or by any court, domestic or foreign, that could reasonably be
     expected to (a) make the acceptance for payment of, or the payment for,
     some or all of the Shares illegal or otherwise prohibited, (b) impose
     limitations on the ability of the Parent or the Purchaser to acquire or
     hold or to exercise effectively all rights of ownership of Shares,
     including, without limitation, the right to vote any Shares purchased by
     either of them on all matters properly 

                                      22

<PAGE>
 
     presented to the stockholders of the Company, or (c) prohibit or impose any
     material limitation on the Parent's or the Purchaser's ownership or
     operation of all or a material portion of the assets or business of the
     Company or any of its subsidiaries or affiliates; or

          (v)  the Company, the Parent or the Purchaser shall have failed to
     receive any or all governmental consents and approvals necessary to
     consummate the Offer, which, if not received, could reasonably be expected
     to have a Material Adverse Effect; or

          (vi)  the Board of Directors of the Company shall have publicly
     (including by amendment of the Schedule 14D-9) withdrawn or amended in any
     respect its recommendation of the Offer or shall have resolved to do so,
     unless such withdrawal or amendment results from a material breach by
     Parent or Purchaser of any representations or warranties in the Merger
     Agreement or a failure by Parent or Purchaser to fulfill any material
     covenant therein.

  The foregoing conditions are for the sole benefit of the Parent and the
Purchaser, may be asserted by the Parent or the Purchaser regardless of the
circumstance giving rise to such condition and, subject to the terms of the
Merger Agreement, may be waived by the Parent and the Purchaser, in whole or in
part at any time and from time to time, in their sole discretion (except that
the Minimum Condition may not be waived by the Purchaser without the consent of
the Company).  The failure by the Parent and the Purchaser at any time to
exercise any of the foregoing rights will not be deemed a waiver of any such
right and each such right will be deemed an ongoing right, which may be asserted
at any time and from time to time.  Any determination by the Parent and the
Purchaser shall be final and binding upon all parties, including tendering
stockholders.

  14.  CERTAIN LEGAL MATTERS.  Except as described in this Section 14, based on
information provided by the Company, neither the Purchaser nor the Parent is
aware of (i) any license or regulatory permit that appears to be material to the
business of the Company and its subsidiaries taken as a whole which might be
adversely affected by the Purchaser's acquisition of Shares as contemplated
herein or (ii) any approval or other action by any governmental, administrative
or regulatory agency or authority that would be required for the acquisition or
ownership of Shares by the Purchaser as contemplated herein.  Should any such
approval or other action be required, the Parent and the Purchaser currently
contemplate that such approval or other action will be sought.  There can be no
assurance, however, that any such approval or other action, if needed, would be
obtained or would be obtained without substantial conditions, or that failure to
obtain any such approval or other action might not result in consequences
adverse to the Company's business, or that certain parts of the Company's
business might not have to be disposed of in the event that such approvals were
not obtained or such other actions were not taken or in order to obtain any such
approval or other action.  If certain types of adverse action are taken with
respect to the matters discussed below, the Purchaser could decline to accept
for payment or pay for any Shares tendered.  See Section 13 for certain
conditions to the Offer and Section 11 for certain conditions to the Merger,
including conditions with respect to litigation and governmental approvals.

  State Takeover Statutes.  A number of states have adopted state "takeover"
statutes and regulations which purport, to varying degrees, to be applicable to
attempts to acquire securities of corporations that are incorporated or have
substantial assets, stockholders, principal executive offices or a principal
place of business in such states. Except for (S)203 of the DGCL discussed below,
the Purchaser does not believe that any of these statutes will by their terms
apply to the Offer, and the Purchaser may not have complied with certain of
these statutes. The Purchaser reserves the right to challenge the applicability
of any state law purporting to apply to the Offer (including (S)203 of the
DGCL), and neither anything in this Offer nor any action taken in connection
herewith is intended as a waiver of such right. To the extent that certain
provisions of these statutes or regulations may purport to apply to the Offer,
the Purchaser believes that there are reasonable bases for contesting such
statutes or regulations. In the event that it were to be asserted that one or
more state takeover statutes or regulations are applicable to the Offer, and an
appropriate court does not determine that they are inapplicable or invalid as
applied to the Offer, the Purchaser might be required to file certain
information with, or to receive approvals from, the relevant state authorities,
and the Purchaser might be unable to accept for payment or pay for Shares
tendered pursuant to the Offer, or be delayed in continuing or consummating the
Offer. In that case, the Purchaser may not be obligated to accept for payment or
pay for any tendered Shares.

                                      23

<PAGE>
 
  The State of Delaware has adopted (S)203 of the DGCL, entitled "Business
Combinations with Interested Stockholders," which is intended to regulate
certain business combinations involving Delaware corporations, such as the
Company.  The restrictions contained in (S)203 of the DGCL, however, will not
apply to the Offer, the Merger and the Stock Tender Agreements because such
transactions have been unanimously approved by the Board of Directors.

  Antitrust.  Pursuant to the requirements of the HSR Act, the Parent and the
Company each filed a Notification and Report Form with the FTC and the Antitrust
Division with respect to the Offer on March 20, 1995 and March 21, 1995,
respectively.  See Section 2.

  The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed acquisition
of the Company pursuant to the Offer and the Merger.  At any time before or
after the Purchaser's purchase of Shares or the consummation of the Merger, the
FTC or the Antitrust Division could take such action under the antitrust laws as
it deems necessary or desirable in the public interest, including seeking to
enjoin the purchase of Shares pursuant to the Offer or the consummation of the
Merger or seeking the divestiture of Shares purchased by the Purchaser or the
divestiture of substantial assets of the Parent, the Company or their respective
subsidiaries.  The Purchaser and the Parent do not believe that consummation of
the Offer and the Merger will result in violation of any applicable antitrust
laws.  However, there can be no assurance that a challenge to the Offer or the
Merger on antitrust grounds will not be made or, if such a challenge is made, of
the result thereof.

  15.  FEES AND EXPENSES.  The Purchaser has retained Morrow & Co., Inc. to act
as the Information Agent and Harris Trust Company of New York to act as
Depositary in connection with the Offer.  The Information Agent may contact
holders of Shares and may request brokers, dealers, banks, trust companies and
other nominee stockholders to forward the Offer material to beneficial owners. 
The Parent will pay the Information Agent and the Depositary aggregate
compensation of approximately $5,000, plus expenses, for their services, and the
Information Agent and the Depositary will be indemnified against certain
liabilities and expenses in connection therewith.

  Neither the Parent nor the Purchaser will pay any fees or commissions to any
broker or dealer or other person (other than the Information Agent) for
soliciting tenders of Shares pursuant to the Offer.  Brokers, dealers,
commercial banks and trust companies will be reimbursed by the Purchaser for
customary mailing and handling expenses incurred by them in forwarding material
to their customers.

  16.  MISCELLANEOUS.  The Offer is not being made to (nor will tenders be
accepted from or on behalf of) holders of Shares in any jurisdiction in which
the making of the Offer or the acceptance thereof would not be in compliance
with the laws of such jurisdiction.  In any jurisdiction the securities laws or
blue sky laws of which require the Offer to be made by a licensed broker or
dealer, the Offer may be made on behalf of the Purchaser by one or more
registered brokers or dealers that are licensed under the laws of such
jurisdiction.

  No person has been authorized to give any information or to make any
representation on behalf of the Purchaser or the Parent not contained herein or
in the Letter of Transmittal and, if given or made, such information or
representation must not be relied upon as having been authorized.

  The Purchaser has filed with the SEC a Statement on Schedule 14D-1 (including
exhibits) pursuant to Rule 14d-3 under the Exchange Act furnishing certain
additional information with respect to the Offer.  Among the exhibits so filed
is a copy of each of the Merger Agreement and the Stock Tender Agreements.  In
addition, the Company has filed with the SEC a Statement on Schedule 14D-9
(including exhibits) pursuant to Rule 14d-9 under the Exchange Act.  Such
Statements and any amendments thereto, including exhibits, may be inspected and
copies may be obtained from the offices of the SEC and the AMEX in the manner
set forth in Section 8 of this Offer to Purchase (except that they will not be
available at the regional offices of the SEC).

                   NOTE:  SIGNATURES MUST BE PROVIDED BELOW.

             PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

 Ladies and Gentlemen:

   The undersigned hereby tenders to WMI Acquisition Sub, Inc., a Delaware
 corporation (the "Purchaser") and a wholly owned subsidiary of Waste
 Management, Inc., an Illinois corporation (the "Parent"), the above described
 shares of common stock, par value $1.00 per share (the "Shares"), of Resource
 Recycling Technologies, Inc., a Delaware corporation (the "Company"), pursuant
 to Purchaser's offer to purchase all outstanding Shares at a price of $11.50
 per Share, net to the seller in cash (the "Purchase Price"), upon the terms and
 subject to the conditions set forth in the Offer to Purchase dated March 23,
 1995 (the "Offer to Purchase"), receipt of which is hereby acknowledged, and in
 accordance with this Letter of Transmittal (which together constitute the
 "Offer").

   Subject to, and effective upon, acceptance for payment of the Shares tendered
 herewith in accordance with the terms and subject to the conditions of the
 Offer, the undersigned hereby sells, assigns, and transfers to, or upon the
 order of, the Purchaser all right, title, and interest in and to all Shares
 tendered hereby (and any and all other shares, dividends, distributions,
 rights, and other securities or property issued or issuable or distributed or
 distributable in respect thereof on or after March 17, 1995 in respect of such
 Shares (collectively "Distributions")) and irrevocably appoints the Depositary
 the true and lawful agent and attorney-in-fact of the undersigned with respect
 to such Shares (and any Distributions) with full power of substitution (such
 power of attorney being deemed to be an irrevocable power coupled with an
 interest) to (i) deliver certificates for such Shares (and any Distributions),
 or transfer ownership of such Shares (and any Distributions) on the account
 books maintained by a Book-Entry Transfer Facility, together in either such
 case with all accompanying evidences of transfer and authenticity, to or upon
 the order of the Purchaser, upon receipt by the Depositary, as the
 undersigned's agent, of the Purchase Price, (ii) present such Shares (and any
 Distributions) for registration and transfer on the books of the Company, and
 (iii) receive all benefits and otherwise exercise all rights of beneficial
 ownership of such Shares (and any Distributions), all in accordance with the
 terms of the Offer.

   The undersigned hereby irrevocably appoints Joseph M. Holsten and T. Michael
 O'Brien, Jr., and each of them, or any other designees of the Purchaser,
 attorneys-in-fact and proxies of the undersigned, each with full power of
 substitution, to vote in such manner as each such attorney and proxy or the
 substitute for any such attorney and proxy shall in the sole discretion of each
 such attorney and proxy deem proper, and otherwise act (including pursuant to
 written consent) with respect to all the Shares tendered hereby (and any
 Distributions) which have been accepted for payment by the Purchaser prior to
 the time of such vote or other action, which the undersigned is entitled to
 vote at any meeting of stockholders (whether annual or special and whether or
 not an adjourned meeting) of the Company, or otherwise.  This power of attorney
 and proxy is coupled with an interest in the Company and in the Shares and is
 irrevocable and is granted in consideration of, and is effective upon, the
 Purchaser's oral or written notice to the Depositary of its acceptance for
 payment of such Shares in accordance with the terms of the Offer.  Such
 acceptance for payment shall revoke all prior powers of attorney and proxies
 appointed by the undersigned at any time with respect to such Shares (and any
 Distributions) and no subsequent powers of attorney or proxies may be given
 (and if given will not be effective) with respect thereto by the undersigned.
 The undersigned acknowledges that the Purchaser expressly reserves the right to
 require that, in order for Shares to be deemed validly tendered, immediately
 upon the acceptance for payment of such Shares (and any Distributions), the
 Purchaser or the Purchaser's designee is able to exercise full voting and other
 rights of a record and beneficial holder with respect to such Shares (and any
 Distributions).

   The undersigned hereby represents and warrants that: (i) the undersigned has
 full power and authority to tender, sell, assign, and transfer the Shares (and
 any Distributions) tendered hereby and (ii) when the same are accepted for
 payment by the Purchaser, the Purchaser will acquire good, marketable, and
 unencumbered title thereto, free and clear of all liens, restrictions, charges,
 claims, and encumbrances, and the same will not be subject to any adverse
 claim.  The undersigned, upon request, will execute and deliver any signature
 guarantee or additional documents deemed by the Depositary or the Purchaser to
 be necessary or desirable to complete or confirm the sale, assignment, and
 transfer of the Shares (and any Distributions) tendered hereby.  In addition,
 the undersigned shall promptly remit and transfer to the Depositary for the
 account of the Purchaser any and all Distributions accompanied by 
 appropriate documentation of transfer, and, pending such remittance or
 appropriate assurance thereof, the Purchaser shall be entitled to all rights
 and privileges as owner of such Distributions and may withhold the entire
 Purchase Price or deduct from the Purchase Price the amount or value thereof,
 as determined by the Purchaser in its sole discretion.

 Transmittal shall not be affected by, and shall survive, the death or
 incapacity of the undersigned, and any obligation of the undersigned hereunder
 shall be binding upon the heirs, executors, administrators, trustees in
 bankruptcy, personal and legal representatives, successors, and assigns of the
 undersigned.  Except as stated in the Offer to Purchase, this tender is

 withdrawn at any time prior to the Expiration Date.

   The undersigned understands that the acceptance for payment of tendered
 Shares pursuant to any of the procedures described in Section 3 of the Offer to

 Act of 1934, as amended (the "Exchange Act"), and (ii) the tender of such
 Shares complies with Rule 14e-4.  The undersigned recognizes that under certain
 circumstances set forth in the Offer to Purchase, the Purchaser may not be
 required to accept for payment any of the Shares tendered hereby.

 please issue the check for the Purchase Price and/or return any certificates
 for Shares not tendered or accepted for payment in the names of the
 undersigned.  Similarly, unless otherwise indicated under "Special Delivery
 Instructions," please mail the check for the Purchase Price and/or return any

 Special Delivery Instructions and the Special Payment Instructions are
 completed, please issue the check for the Purchase Price and/or return any

 and deliver said check and/or certificates to, the person or persons so
 indicated.  In the case of a book-entry delivery of Shares, please credit the
 account maintained at the Book-Entry Transfer Facility indicated above with any
 Shares not accepted for payment.  The undersigned recognizes that the Purchaser
 has no obligation pursuant to the Special Payment Instructions to transfer any
 Shares from the name of the registered holder thereof if the Purchaser does not
 accept for payment any of the Shares so tendered.

                                 INSTRUCTIONS

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

  1.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required if (i) this Letter of Transmittal is signed by the
registered holders of Shares (which term, for purposes of this document, shall
include any participant in a Book-Entry Transfer Facility whose name appears on
a security position listing as the owner of Shares) tendered herewith unless
such holders have completed either the box entitled "Special Delivery
Instructions" or "Special Payment Instructions" on this Letter of Transmittal,
or (ii) such Shares are tendered for the account of a firm or other entity
identified in rule 17Ad-15 under the Exchange Act, including (as such terms are
defined therein) any (a) bank, (b) broker, dealer, municipal securities dealer,
municipal securities broker, government securities dealer, or government
securities broker, (c) credit union, (d) national securities exchange,
registered securities association, or clearing agency, or (e) savings
association (in each case, an "Eligible

                                       5

<PAGE>

 Institution"). In all other cases, all signatures on this Letter of Transmittal
 must be guaranteed by an Eligible Institution, acting in accordance with the
 procedures set forth in such Rule, which is a member in good standing of the
 Securities Transfer Agents Medallion Program. If the certificate is registered
 in the name of a person other than the signer of this Letter of Transmittal,
 the tendered certificate must be endorsed or accompanied by appropriate stock
 powers signed exactly as the name or names of the registered owner or owners
 appears on the certificate, with the signatures on the certificate or stock
 powers guaranteed as aforesaid. See Instruction 5.

   2.  DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES.  This Letter of
 Transmittal is to be completed by stockholders either if certificates are to be
 forwarded herewith or if tenders are to be made pursuant to the procedures for
 delivery by book-entry transfer set forth in Section 3 of the Offer to
 Purchase.  Certificates for all physically tendered Shares, or Book-Entry
 Confirmation, as the case may be, as well as a properly completed and duly
 executed Letter of Transmittal (or manually signed facsimile hereof) or an
 Agent's Message (in connection with book-entry transfer) and any other
 documents required by this Letter of Transmittal, must be received by the
 Depositary at one of its addresses set forth herein on or prior to the
 Expiration Date, or the tendering stockholder must comply with the guaranteed
 delivery procedures set forth below.

   Stockholders whose certificates for Shares are not immediately available or
 who cannot deliver their certificates and all other required documents to the
 Depositary on or prior to the Expiration Date, or who cannot complete the
 procedure for book-entry transfer on a timely basis, may tender their Shares
 pursuant to the guaranteed delivery procedures set forth in Section 3 of the
 Offer to Purchase.  Pursuant to such procedures, (i) such tender  must be made
 by or through a member of a registered national securities exchange, a member
 of the National Association of Securities Dealers, Inc. ("NASD"), or a
 commercial bank or trust company having an office or correspondent in the
 United States, (ii) a properly completed and duly executed Notice of Guaranteed
 Delivery, substantially in the form provided by the Purchaser, must be received
 by the Depositary, either by hand delivery, mail, telegram, or facsimile
 transmission, on or prior to the Expiration Date, and (iii) the certificates
 for all physically tendered Shares, in proper form for transfer, or Book-Entry
 Confirmation, as the case may be, together with a properly completed and duly
 executed Letter of Transmittal (or manually signed facsimile thereof), or, in
 the case of book-entry transfer, an Agent's Message, and any other documents
 required by this Letter of Transmittal, must be received by the Depositary
 within five American Stock Exchange ("AMEX") trading days after the date of the
 execution of the Notice of Guaranteed Delivery.

   The term "Agent's Message" means a message, transmitted by a Book-Entry
 Transfer Facility to, and received by, the Depositary and forming a part of a
 Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
 has received an express acknowledgment from the participant in such Book-Entry
 Transfer Facility tendering the Shares which are the subject of such Book-Entry
 Confirmation that such participant has received and agrees to be bound by the
 terms of this Letter of Transmittal and that the Purchaser may enforce such
 agreement against such participant.

   THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE CERTIFICATES FOR
 SHARES, AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE
 TENDERING STOCKHOLDER.  IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN
 RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.  AMPLE TIME SHOULD BE
 ALLOWED FOR SUCH DOCUMENTS TO REACH THE DEPOSITARY.  EXCEPT AS OTHERWISE
 PROVIDED IN THIS INSTRUCTION 2, DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY
 RECEIVED BY THE DEPOSITARY.

   No alternative, conditional, or contingent tenders will be accepted and no
 fractional Shares will be purchased.  All tendering stockholders, by execution
 of this Letter of Transmittal (or facsimile thereof), waive any right to
 receive any notice of the acceptance of their Shares for payment.

   3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
 certificate numbers and/or the number of Shares should be listed on a separate
 signed schedule attached hereto.

   4.  PARTIAL TENDERS.  (Not applicable to stockholders who tender by book-
 entry transfer.)  If fewer than all the Shares evidenced by any certificate
 submitted are to be tendered, fill in the number of Shares that are to be
 tendered in the box entitled "Number of Shares Tendered."  In such case, new
 certificates for the remainder of the shares that were evidenced by old
 certificates will be sent to the registered holder, unless otherwise provided
 in the appropriate box on this Letter of Transmittal, as soon as practicable
 after the Expiration Date.  All Shares represented by certificates delivered to
 the Depositary will be deemed to have been tendered unless otherwise indicated.

   5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS, AND ENDORSEMENTS.  If
 this Letter of Transmittal is signed by the registered owners of the Shares
 tendered hereby, the signatures must correspond to the names as written on the
 face of the certificates without alteration, enlargement, or any change
 whatsoever.

   If any of the Shares tendered hereby are held of record by two or more joint
 owners, all such owners must sign this Letter of Transmittal.

   If any of the Shares tendered hereby are registered in different names on
 several certificates, it will be necessary to complete, sign, and submit as
 many separate Letters of Transmittal as there are different registrations of
 certificates.

   If this Letter of Transmittal or any certificate or stock power is signed by
 a trustee, executor, administrator, guardian, attorney-in-fact, agent, officer
 of a corporation, or other person acting in a fiduciary or representative
 capacity, such person should so indicate when signing, and proper evidence
 satisfactory to the Purchaser of such person's authority to so act must be
 submitted.

   When this Letter of Transmittal is signed by the registered owners of the
 Shares listed and transmitted hereby, no endorsements of certificates or
 separate stock powers are required unless payment is to be made, or
 certificates for Shares not tendered or purchased are to be issued, to a person
 other than the registered owners in which case signatures on such certificates
 or stock powers must be guaranteed by an Eligible Institution which is a member
 in good standing of the Securities Transfer Agents Medallion Program.

   If this Letter of Transmittal is signed other than by the registered owners
 of the certificates listed, the certificates must be endorsed or accompanied by
 appropriate stock powers, in either case signed exactly as the name or names of
 the registered owners appear on the certificates and signatures on such
 certificates or stock powers are required, and must be guaranteed by an
 Eligible Institution which is a member in good standing of the Securities
 Transfer Agents Medallion Program, unless the signature is that of an Eligible
 Institution which is a member in good standing of the Securities Transfer
 Agents Medallion Program.

   6.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check and/or
 certificates for unpurchased or untendered Shares are to be issued in the name
 of a person other than the signer of this Letter of Transmittal, or if a check
 is to be sent and/or such certificates are to be returned to someone other than
 the signer of this Letter of Transmittal or to an address other than that shown
 above, the appropriate boxes on this Letter of Transmittal should be completed.
 If no such instructions are given, such Shares not purchased will be returned
 by crediting the account at the Book-Entry Transfer Facility designated above.

   7.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 7, the
 Purchaser will pay or cause to be paid any stock transfer taxes with respect to
 the transfer and sale of the purchased Shares to it, or to its order, pursuant
 to the Offer.  If payment of the Purchase Price is to be made to, or if
 certificates for Shares not tendered or purchased are to be registered in the
 name of, any persons other than the registered owners, or if tendered
 certificates are registered in the name of any persons other than the persons
 signing this Letter of Transmittal, the amount of any stock transfer taxes
 (whether imposed on the registered owner or such other person) payable on
 account of the transfer to such other person will be deducted from the Purchase
 Price unless satisfactory evidence of the payment of such taxes or exemption
 therefrom is submitted.
 
   Except as provided in this Instruction 7, it will not be necessary for
 transfer tax stamps to be affixed to the certificates listed in this Letter of
 Transmittal.

   8.  WAIVER OF CONDITIONS.  The conditions of the Offer (other than the
 Minimum Condition (as defined in the Offer to Purchase), without the Company's
 prior written consent) may be waived by Purchaser, in whole or in part, at any
 time and from time to time in Purchaser's sole discretion, in the case of any
 Shares tendered.

   9.  SUBSTITUTE FORM W-9.  Each tendering stockholder (or other payee) is
 required to provide the Depositary with a correct taxpayer identification
 number ("TIN"), generally the stockholder's social security or federal employer
 identification number, and with certain other information, on Substitute Form
 W-9, which is provided under "Important Tax Information" below, and to certify
 that the stockholder (or other payee) is not subject to backup withholding.
 Failure to provide the information on the Substitute Form W-9 may subject the
 tendering stockholder (or other payee) to 31% federal income tax withholding on
 the payment of the Purchase Price.  The box in Part 3 of the Substitute Form W-
 9 may be checked if the tendering stockholder (or other payee) has not been

                                       7

<PAGE>

 issued a TIN and has applied for a TIN or intends to apply for a TIN in the
 near future.  If the box in Part 3 is checked and the Depositary is not
 provided with a TIN by the time of payment, the Depositary will withhold 31% on
 all such payments of the Purchase Price until a TIN is provided to the
 Depositary.

   10.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance
 may be directed to the Information Agent at the addresses set forth below.
 Additional copies of the Offer to Purchase, this Letter of Transmittal, the
 Notice of Guaranteed Delivery, and the Guidelines for Certification of Taxpayer
 Identification Number on Substitute Form W-9 may be obtained from the
 Information Agent at the addresses set forth below or from your broker, dealer,
 commercial bank, trust company, or other nominee.

   IMPORTANT:  THIS LETTER OF TRANSMITTAL (OR A MANUALLY EXECUTED FACSIMILE
 HEREOF), TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND
 ALL OTHER REQUIRED DOCUMENTS OR THE NOTICE OF GUARANTEED DELIVERY, MUST BE
 RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.

                           IMPORTANT TAX INFORMATION

   Under federal income tax law, a stockholder whose tendered Shares are
 accepted for payment is required to provide the Depositary with such
 stockholder's current TIN on Substitute Form W-9 below.  If such stockholder is
 an individual, the TIN is the stockholder's social security number.  If the
 Depositary is not provided with the correct TIN, the stockholder or other payee
 may be subject to a penalty imposed by the Internal Revenue Service.  In
 addition, payments that are made to such stockholder or other payee with
 respect to Shares purchased pursuant to the Offer may be subject to 31% backup
 withholding.

   Certain stockholders (including, among others, all corporations and certain
 foreign individuals) are not subject to these backup withholding and reporting
 requirements.  In order for a foreign individual to qualify as an exempt
 recipient, that stockholder must submit to the Depositary a statement, signed
 under penalties of perjury, attesting to that individual's exempt status.  Such
 statements can be obtained from the Depositary or the Information Agent.  See
 the enclosed "Guidelines for Certification of Taxpayer Identification Number on
 Substitute Form W-9" for additional instructions.

   If backup withholding applies, the Depositary is required to withhold 31% of
 any payment made to the stockholder or other payee.  Backup withholding is not
 an additional federal income tax.  Rather, the federal income tax liability of
 persons subject to backup withholding will be reduced by the amount of such tax
 withheld.  If backup withholding results in an overpayment of taxes, a refund
 may be obtained from the Internal Revenue Service.

 PURPOSE OF SUBSTITUTE FORM W-9

   To prevent backup withholding on payments made to a stockholder or other
 payee with respect to Shares purchased pursuant to the Offer, the stockholder
 is required to notify the Depositary of the stockholder's current TIN (or the
 TIN of any other payee) by completing the form below, certifying that the TIN
 provided on Substitute Form W-9 is correct (or that such stockholder is
 awaiting a TIN), and that (1) the stockholder has not been notified 
 by the Internal Revenue Service that the stockholder is subject to backup
 withholding as a result of failure to report all interest or dividends or (2)
 the Internal Revenue Service has notified the stockholder that the stockholder
 is no longer subject to backup withholding.

 WHAT NUMBER TO GIVE THE DEPOSITARY

   The stockholder is required to give the Depositary the TIN (e.g., social
 security number or employer identification number) of the record owner of the
 Shares. If the Shares are registered in more than one name or are not
 registered in the name of the actual owner, consult the enclosed "Guidelines
 for Certification of Taxpayer Identification Number on Substitute Form W-9,"
 for additional guidance on which number to report.

To Brokers, Dealers, Commercial Banks,

Purchaser's Offer to Purchase dated March 23, 1995 (the "Offer to Purchase") and
the related Letter of Transmittal (which together constitute the "Offer").

  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OF THE
MINIMUM CONDITION, AS DEFINED IN THE OFFER TO PURCHASE.

  For your information and for forwarding to your clients for whom you hold
shares registered in your name or in the name of your nominee, or who hold

     1.  The Offer to Purchase;

     2.  A Letter of Transmittal to be used by stockholders in accepting the

  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extensions or
amendment), the Purchaser will be deemed to have accepted for payment (and
thereby purchased), and will pay for, all Shares validly tendered prior to the
Expiration Date and not properly withdrawn if, as, and when the Purchaser gives
oral or written notice to the Depositary of the Purchaser's acceptance of such
Shares for payment pursuant to the Offer.  In all cases, payment for Shares
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of certificates evidencing such Shares, or timely confirmation of a
book-entry transfer of such Shares into the Depositary's account at The
Depository Trust Company, the Midwest Securities Trust Company, or the
Philadelphia Depository Trust Company, pursuant to the procedures described in
Section 3 of the Offer to Purchase, a properly completed and duly executed
Letter of Transmittal (or facsimile thereof), or an Agent's Message (in
connection with book-entry transfer), and any other documents required by the
Letter of Transmittal.

  The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares which are the subject of such Book-Entry
Confirmation that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal and that the Purchaser may enforce such
agreement against such participant.

  The Purchaser will pay any transfer taxes applicable to the sale and transfer
of Shares to it or its order, except as otherwise set forth in Instruction 7 of
the Letter of Transmittal.  The Purchaser will not pay any commission or fee to
any broker or dealer or other person (other than to the Depositary or the
Information Agent, as described in the Offer to Purchase) in connection with the
solicitation of tenders of Shares pursuant to the Offer.  The Purchaser will,
however, upon request, reimburse brokers, dealers, commercial banks, trust
companies, and other nominees for their reasonable and necessary costs incurred
in forwarding the Offer to Purchase and the related documents to the beneficial
owners of Shares held by them as nominee or in a fiduciary capacity.  If holders
of Shares wish to tender, but it is impracticable for them to forward their
certificates or other required documents prior to the expiration of the  Offer,
a tender may be effected by following the guaranteed delivery procedure
described in Section 3 of the Offer to Purchase.

  Additional copies of the enclosed material may be obtained from, and any
inquires you may have with respect to the Offer should be addressed to, the
undersigned at the respective addresses and telephone numbers set forth on the

Exempt payees described above should file Form W-9 to avoid possible erroneous

IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYER.  IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS,
ALSO SIGN AND DATE THE FORM.

PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS.  IRS uses the numbers for identification
purposes.  Payers must be given the numbers whether or not recipients are
required to file tax returns. Payers must generally withhold 31% of taxable
interest, dividend, and certain other payments to a payee who does not furnish a
taxpayer identification number to a payer.  Certain penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your taxpayer identification number to a payer, you are subject to a
penalty of $50 for each such failure unless your failure is due to reasonable
cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an under-
payment attributable to that failure unless there is clear and convincing
evidence to the contrary.

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.

jurisdiction in which the making of the Offer or the acceptance thereof would
not be in compliance with the laws of such jurisdiction. In any jurisdiction
where the securities, blue sky, or other laws require the Offer to be made by a
licensed broker or dealer, the Offer will be deemed to be made on behalf of the
Purchaser by one or more registered brokers or dealers licensed under the laws
of such jurisdiction.

                            WASTE MANAGEMENT, INC.

  WMI Acquisition Sub, Inc., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of Waste Management, Inc. (the "Parent"), is offering to
purchase all outstanding shares of Common Stock, par value $1.00 (the "Shares"),
of Resource Recycling Technologies, Inc., a Delaware corporation (the
"Company"), at $11.50 per Share, net to the seller in cash, upon the terms and
subject to the conditions set forth in the Offer to Purchase dated March 23,
1995 (the "Offer to Purchase") and in the related Letter of Transmittal (which
together constitute the "Offer").

   THE OFFER AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY
   TIME, ON WEDNESDAY, APRIL 19, 1995, UNLESS THE OFFER IS EXTENDED.

  The Offer is conditioned upon, among other things, there being validly
tendered by the Expiration Date (as defined in the Offer to Purchase) and not
withdrawn that number of Shares representing 50.1% or more of the total number
of Shares that would be outstanding if all outstanding rights to acquire Shares
were exercised (the "Minimum Condition").  See Section 13 of the Offer to
Purchase for certain other conditions.

  The Offer is also subject to certain other conditions set forth in the Offer
to Purchase.  If any condition is not satisfied, the Purchaser may, subject to
the terms of an Agreement and Plan of Merger dated March 17, 1995 (the "Merger
Agreement"), by and among the Company, the Purchaser and the Parent, (i)
terminate the Offer and return all tendered Shares to tendering stockholders,
(ii) extend the Offer and, subject to withdrawal rights as set forth below,
retain all such Shares until the expiration of the Offer as so extended, (iii)
waive such condition and, subject to any requirement to extend the time during
which the Offer is open, purchase all Shares validly tendered prior to the
Expiration Date and not withdrawn, or (iv) delay acceptance for payment or
payment for Shares, subject to applicable law, until satisfaction or waiver of
the conditions to the Offer.  Any extension by the Purchaser of the period of
time during which the Offer is open will be made by giving oral or written
notice of such extension to Harris Trust Company of New York (the "Depositary").
Any such extension will be followed as promptly as practicable by public
announcement thereof.

  The purpose of the Offer is to acquire control of, and the entire equity
interest in, the Company.  The Offer is being made pursuant to the Merger
Agreement, which provides that if Shares are purchased pursuant to the Offer,
and subject to certain other conditions, a merger will be effected (the
"Merger") whereby the Company will become a wholly owned subsidiary of the
Parent and each Share (other than Shares held in the treasury of the Company or
owned by the Parent or any of its corporate affiliates or Shares owned by
stockholders who have perfected dissenters' rights) outstanding immediately
before the effectiveness of the Merger will be converted into a right to receive
an amount in cash equal to the cash price per Share paid pursuant to the Offer.
See the Introduction and Section 11 of the Offer to Purchase.

  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER AND
THE MERGER, HAS DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO AND IN THE
BEST INTERESTS OF THE STOCKHOLDERS OF THE COMPANY, AND RECOMMENDS THAT
STOCKHOLDERS ACCEPT THE OFFER.

  For purposes of the Offer, the Purchaser shall be deemed to have accepted for
payment tendered Shares when, as, and if the Purchaser gives oral or written
notice to the Depositary of its acceptance of the tenders of such Shares.
Payment for Shares accepted for payment pursuant to the Offer will be made only
after timely receipt by the Depositary of certificates for such Shares (or a
confirmation of a book-entry transfer of such Shares into the Depositary's
account at one of the Book-Entry Transfer Facilities (as defined in the Offer to
Purchase)), a properly completed and duly executed Letter of Transmittal (or
facsimile thereof) or an Agent's Message, and any other required documents.

  Tenders of Shares made pursuant to the Offer may be withdrawn at any time
prior to the Expiration Date.  Thereafter, such tenders are irrevocable, except
that they may be withdrawn after May 22, 1995 unless theretofore accepted for
payment as provided in the Offer to Purchase.  To be effective, a written,
telegraphic, or facsimile transmission notice of withdrawal must be timely
received by the Depositary at one of its 
<PAGE>
 
addresses set forth in the Offer to Purchase and must specify the name of the
person who tendered the Shares to be withdrawn and the number of Shares to be
withdrawn. If the Shares to be withdrawn have been delivered to the Depositary,
a signed notice of withdrawal with (except in the case of Shares tendered by an
Eligible Institution (as defined in the Offer to Purchase)) signatures
guaranteed by an Eligible Institution, which is a participant in good standing
in the Security Transfer Agents Medallion Program, must be submitted prior to
the release of such Shares. In addition, such notice must specify, in the case
of Shares tendered by delivery of certificates, the name of the registered
holder (if different from that of the tendering stockholder) and the serial
numbers shown on the particular certificates evidencing the Shares to be
withdrawn or, in the case of Shares tendered by book-entry transfer, the name
and number of the account at one of the Book-Entry Transfer Facilities to be
credited with the withdrawn Shares.

  The information required to be disclosed by Rule 14d-6(e)(1)(vii) of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, is contained in the Offer to Purchase and is incorporated herein by
reference.

  The Company has agreed to furnish the Purchaser with a copy of its stockholder
list and security position listings for the purpose of disseminating the Offer
to holders of Shares.  The Offer to Purchase and the related Letter of
Transmittal will be mailed to record holders of Shares and will be furnished to
brokers, banks, and similar persons whose names, or the names of whose nominees,
appear on the stockholder list or, if applicable, who are listed as participants
in a clearing agency's security position listing for subsequent transmittal to
beneficial owners of Shares.  The Offer to Purchase and Letter of Transmittal
contain important information which should be read before any decision is made
with respect to the Offer.

Transmittal and other tender offer materials may be directed to the Information

                          AGREEMENT AND PLAN OF MERGER

                                 March 17, 1995


          The parties to this Agreement and Plan of Merger are Waste Management,
Inc., an Illinois corporation (the "Parent"), WMI Acquisition Sub, Inc., a
Delaware corporation, and a wholly-owned subsidiary of the Parent (the "Sub"),
and Resource Recycling Technologies, Inc., a Delaware corporation (the
"Company").

          The parties wish to provide for the merger of the Sub with and into
the Company on the terms and conditions set forth in this agreement.

          Accordingly, the parties agree as follows:

1.   The Offer.

     1.1  General.

          (a) As promptly as practicable (but in no event later than five
business days after the date of this Agreement), the Parent shall cause the Sub
to commence (within the meaning of Rule 14d-2 under the Securities Exchange Act
of 1934, as amended (the "Exchange Act") an offer (the "Offer") to purchase all
the outstanding shares of common stock, par value $1.00 per share (the "Company
Common Stock"), of the Company at a price of $11.50 per share, net to the seller
in cash (the "Offer Price"), and, subject to the conditions of the Offer, shall
use all reasonable efforts to consummate the Offer as promptly as permitted by
law.  The obligation of the Parent and the Sub to consummate the Offer and to
accept for payment and to pay for any shares of Company Common Stock tendered
pursuant to the Offer (i) shall be subject to the condition that such number of
shares of Company Common Stock shall have been validly tendered and not
withdrawn prior to the expiration date of the Offer that, together with the
shares of Company Common Stock beneficially owned by the Parent and any
affiliate of the Parent on that date, constitute more than 50.1% of Company
Common Stock, assuming exercise and conversion of all outstanding options and
convertible securities of the Company (the "Minimum Condition") and (ii) shall
be subject to the other conditions set forth in Annex A to this Agreement.

          (b) Neither the Parent nor the Sub shall, without the consent of the
Company, waive the Minimum Condition.  Otherwise, the conditions of the Offer
are for the sole benefit of the Sub and the Parent regardless of the
circumstances giving rise to the non-fulfillment of any such conditions and may
be waived by the Sub and the Parent in whole or in part.  The Company agrees
that no shares of Company Common Stock held by the Company shall be tendered
pursuant to the Offer.  Parent and Sub may modify the terms of the Offer, except
that, without the consent of the Company, they shall not (i) reduce the number
of shares of Company Common Stock to be purchased in the Offer, (ii) reduce the
Offer Price, (iii) modify or add to the conditions set forth in Annex A, (iv)
except as provided in the next sentence, extend the Offer, (v) change the form
of consideration payable in the Offer, or (vi) amend any other term of the 
<PAGE>
 
Offer in a manner adverse to the holders of Company Common Stock.
Notwithstanding the foregoing, Parent and Sub may, without the consent of the
Company, (i) extend the Offer beyond any scheduled expiration date (the initial
scheduled expiration date being 20 business days following commencement of the
Offer) for a period not to exceed 20 business days, if at any scheduled
expiration date of the Offer, any of the conditions to Sub's obligation to
accept for payment, and pay for, shares of Company Common Stock shall not be
satisfied or waived, until such time as such conditions are satisfied or waived,
(ii) extend the Offer for any period required by any rule, regulation,
interpretation or position of the Securities and Exchange Commission (the "SEC")
or the staff thereof applicable to the Offer, and (iii) extend the Offer for an
aggregate period of not more than 15 business days beyond the latest expiration
date that would otherwise be permitted under clause (i) or (ii) of this sentence
if there shall not have been tendered sufficient shares of Company Common Stock
so that the Merger could be effected as provided in Section 2.12. Subject to the
terms and conditions of the Offer and this Agreement, Sub shall, and Parent
shall cause Sub to, accept for payment, and pay for, all shares of Company
Common Stock validly tendered and not withdrawn pursuant to the Offer that Sub
becomes obligated to accept for payment, and pay for, pursuant to the Offer as
soon as practicable after expiration of the Offer.

          (c) As soon as practicable on the date of commencement of the Offer,
the Sub shall file with the SEC a Tender Offer Statement on Schedule 14D-1 with
respect to the Offer, which will contain the offer to purchase and form of the
related letter of transmittal (which, together with any supplements or
amendments to those documents, are collectively referred to as the "Offer
Documents").  The Sub and the Parent shall cause the Offer Documents to comply
in all material respects with the provisions of applicable federal securities
laws and, on the date filed with the SEC and on the date first published, sent
or given to the Company's stockholders, not to contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading (except that neither the
Parent nor the Sub shall be responsible with respect to information supplied by
the Company in writing for inclusion in the Offer Documents).  Each of the
Parent, the Sub and the Company shall promptly correct any information provided
by it for use or used in the Offer Documents, if and to the extent such
information shall have become false or misleading in any material respect, and
the Sub and the Parent shall take all steps necessary to cause the Offer
Documents as so corrected to be filed with the SEC and to be disseminated to
holders of shares of Company Common Stock, in each case as and to the extent
required by applicable federal securities laws.  The Company and its counsel
shall be given a reasonable opportunity to review and comment upon the Offer
Documents and all amendments and supplements thereto prior to their filing with
the SEC or dissemination to stockholders of the Company.  Parent and Sub agree
to provide the Company and its counsel any comments Parent, Sub or their counsel
may receive from the SEC or its staff with respect to the Offer Documents
promptly after the receipt of such comments and shall provide the Company and
its counsel an opportunity to participate, including by way of discussion with
the SEC or its staff, in the response of Parent and/or Sub to such comments.

                                       2
<PAGE>
 
          (d) Parent shall provide or cause to be provided to Sub on a timely
basis the funds necessary to accept for payment, and pay for, any shares of
Company Common Stock that Sub accepts for payment, and becomes obligated to pay
for, pursuant to the Offer.

     1.2  Company Actions.  The Company hereby consents to the Offer and
represents and warrants to the Parent and the Sub that its board of directors
(at a meeting duly called and held) has unanimously (i) determined that as of
the date of such meeting the Offer and the Merger (as defined in Section 2.1(a))
are fair to, and in the best interests of, the Company's stockholders, (ii)
approved this Agreement and the transactions contemplated by this Agreement,
including the Offer, the Stock Tender Agreements (as defined in Section 21 of
Annex A) and the Merger, and (iii) resolved, subject to its fiduciary duties
under applicable law, to recommend acceptance of the Offer and approval and
adoption of this Agreement and the Merger by the stockholders of the Company.
The Company shall file with the SEC contemporaneously with the commencement of
the Offer a Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") containing that recommendation in favor of the Offer and the
Merger.  The Company shall cause the Schedule 14D-9 to comply in all material
respects with the provisions of applicable federal securities laws.  The Company
shall cause the Schedule 14D-9, on the date filed with the SEC and on the date
first published, sent or given to the Company's stockholders, not to contain any
untrue statement of a material fact or to omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not misleading
(except that the Company shall not be responsible with respect to information
supplied by the Parent or the Sub in writing for inclusion in the Schedule 14D-
9).  The Company shall take all steps necessary to cause the Schedule 14D-9 to
be filed with the SEC and mailed to the Company's stockholders to the extent
required by applicable federal securities laws.  The Company shall include in
the Schedule 14D-9, on the date first published, sent or given to the Company's
stockholders, such information with respect to the Company's officers and
directors as is required under Section 14(f) of the Exchange Act and Rule 14f-1
thereunder in order to fulfill its obligations under Section 1.3.  The Parent
and the Sub shall supply the Company with, and be solely responsible for, any
information with respect to themselves and their nominees, officers, directors
and affiliates required by Section 14(f) and Rule 14f-1.  Each of the Company,
Parent and Sub agrees promptly to correct any information provided by it for use
in the Schedule 14D-9 if and to the extent that such information shall have
become false or misleading in any material respect, and the Company further
agrees to take all steps necessary to amend or supplement the Schedule 14D-9 and
to cause the Schedule 14D-9 as so amended or supplemented to be filed with the
SEC and disseminated to the Company's stockholders, in each case as and to the
extent required by applicable federal securities laws.  Parent and its counsel
shall be given a reasonable opportunity to review and comment upon the Schedule
14D-9 and all amendments and supplements thereto prior to their filing with the
SEC or dissemination to stockholders of the Company.  The Company agrees to
provide Parent and its counsel with any comments the Company or its counsel may
receive from the SEC or its staff with respect to the Schedule 14D-9 promptly
after the receipt of such comments and shall provide Parent and its counsel an
opportunity to participate, including by way of discussions with the SEC or its
staff, in the response of the Company to such comments.  In connection with the
Offer, the Company shall promptly furnish the Sub with mailing labels, security
position listings and any available listing or computer file containing the
names and addresses of the record 

                                       3
<PAGE>
 
holders of the Company Common Stock as of a recent date, and shall furnish the
Sub with such information and assistance as the Sub or its agents may reasonably
request in communicating the Offer to the stockholders of the Company. Subject
to the requirements of law, and except for such steps as are necessary to
disseminate the documents constituting the Offer and any other documents
necessary to consummate the Merger, the Parent and the Sub shall, and shall
cause each of their affiliates and associates to, hold in confidence the
information contained in any such labels, lists and other documents, to use such
information only in connection with the Offer and the Merger, and, if this
Agreement is terminated, to deliver to the Company all copies of such
information then in their possession.

     1.3  Directors; Section 14(f).  Promptly upon the purchase by the Parent or
the Sub of at least a majority of the outstanding shares of Company Common Stock
and from time to time thereafter, the Parent and the Sub shall be entitled to
designate such number of directors, rounded up to the next whole number but in
no event more than one less than the total number directors of the board of
directors of the Company as will give the Parent and the Sub, subject to
compliance with Section 14(f) of the Exchange Act, representation on the board
of directors of the Company equal to the product of the number of directors on
the board of directors of the Company and the percentage that such number of
shares of Company Common Stock so purchased bears to the number of shares of
Company Common Stock outstanding, and the Company shall, upon request by the
Parent and the Sub, promptly increase the size of the board of directors of the
Company or exercise all reasonable efforts to secure the resignations of such
number of directors as is necessary to enable the Parent's and the Sub's
designees to be elected to the board of directors of the Company and shall cause
such designees to be so elected.  At the request of the Parent and the Sub, the
Company shall take, at its expense, all action necessary to effect any such
election, including mailing to its stockholders the information required by
Section 14(f) of the Exchange Act and Rule 14f-1 thereunder.  From and after the
date that such designees to the board of directors of the Company constitute a
majority of the board of directors of the Company, any action taken by the
Company under Section 5 or 6 of this Agreement shall require the approval of a
majority of the members of the board of directors, if any, who are not designees
or affiliates of the Parent and the Sub.

2.   The Merger and Related Matters.

     2.1  The Merger.

          (a) Upon the terms and conditions of this Agreement, at the Effective
Time (as defined in Section 2.1(b)), the Sub shall be merged with and into the
Company (the "Merger") in accordance with the provisions of the General
Corporation Law of the State of Delaware (the "GCL") and the separate corporate
existence of the Sub shall cease, and the Company shall continue as the
surviving corporation under the laws of the State of Delaware with its current
corporate name (the "Surviving Corporation").

          (b) The Merger shall become effective at the time of filing of a
certificate of merger with the Secretary of State of the State of Delaware in
accordance with the provisions of Section 251 of the GCL (the "Certificate of
Merger"), or at the time specified as the effective 

                                       4
<PAGE>
 
time in the Certificate of Merger (it being understood that such specified
effective time shall be within a reasonable period, not to exceed five business
days, after the date the Certificate of Merger is filed). The Certificate of
Merger shall be filed at the time of the Closing Date (as defined in Section
2.9). The date and time when the Merger shall become effective is referred to as
the "Effective Time."

          (c) The separate corporate existence of the Company, as the Surviving
Corporation, with all its purposes, objects, rights, privileges, powers,
certificates and franchises, shall continue unimpaired by the Merger.  At the
Effective Time, the separate corporate existence of the Sub shall cease and the
Surviving Corporation shall succeed to all the properties and assets of the
Company and the Sub and to all the debts, choses in action and other interests
due or belonging to the Company and the Sub and shall be subject to, and
responsible for, all the debts, liabilities and duties of the Company with the
effect set forth under the GCL.

     2.2  Conversion of Stock.  At the Effective Time:

          (a) Each share of Company Common Stock then issued and outstanding
(other than Dissenting Shares (as defined in Section 2.3) and any shares of
Company Common Stock held by the Parent or the Sub or any corporate affiliate of
either of them) shall, by virtue of the Merger and without any action on the
part of the holder thereof, be converted into and represent the right to
receive, and shall be exchangeable for, the highest price paid pursuant to the
Offer, subject to applicable withholding or back-up withholding taxes, if any,
payable to the holder thereof, without any interest thereon (the "Merger
Consideration"), upon surrender of the certificates representing such shares of
Company Common Stock.

          (b) Each share of common stock of the Sub (the "Sub Common Stock")
then issued and outstanding shall, by virtue of the Merger and without any
action on the part of the holder thereof, be converted into and become one fully
paid and nonassessable share of common stock of the Surviving Corporation, which
thereafter will constitute all of the issued and outstanding shares of common
stock of the Surviving Corporation.

          (c) Each share of Company Common Stock then held in the treasury of
the Company shall, by virtue of the Merger, be cancelled without payment of any
consideration therefor and without any conversion thereof.

          (d) Each share of Company Common Stock then held by the Sub or the
Parent (or any corporate affiliate of either of them) shall, by virtue of the
Merger and without any action on the part of the holder thereof, be cancelled
without payment of any consideration therefor and without any conversion
thereof.

     2.3  Dissenting Shares.  Notwithstanding anything in this Agreement to the
contrary, none of the shares of Company Common Stock that are outstanding
immediately prior to the Effective Time and that are held by stockholders (other
than the Parent or the Sub or any corporate affiliate of either of them) who
shall not have voted those shares of Company Common Stock in favor of the Merger
and who are entitled by applicable Delaware law to appraisal rights, and who
shall have delivered a written demand for appraisal of those shares of Company

                                       5
<PAGE>
 
Common Stock in the manner provided in Section 262 of the GCL ("Dissenting
Shares") shall be converted into the right to receive, or be exchangeable for,
the Merger Consideration; however, (a) if any holder of Dissenting Shares shall
subsequently deliver a written withdrawal of his demand for appraisal of those
shares of Company Common Stock (with the written approval of the Company, if
such withdrawal is not tendered within 60 days after the Effective Time), or (b)
if any holder fails to establish his entitlement to appraisal rights as provided
in Section 262 of the GCL or (c) if neither any holder of Dissenting Shares nor
the Surviving Corporation has filed a petition demanding a determination of the
value of all Dissenting Shares within the time provided in Section 262 of the
GCL, such holder or holders shall forfeit the right to appraisal of those shares
of Company Common Stock and each such share shall thereupon be deemed to have
been converted into the right to receive, and to have become exchangeable for,
as of the Effective Time, the Merger Consideration.

     2.4  Payment.

          (a) Prior to the Effective Time, the Parent and the Sub shall
designate a bank or trust company reasonably acceptable to the Company to act as
exchange agent in the Merger (the "Exchange Agent").  At or immediately prior to
the Effective Time, the Parent and the Sub shall take all steps necessary to
provide the Exchange Agent with funds necessary to make the payments
contemplated by Section 2.2.

          (b) Promptly after the Effective Time, the Surviving Corporation shall
cause the Exchange Agent to mail to each record holder, as of the Effective
Time, of a certificate or certificates that, immediately prior to the Effective
Time, represented outstanding shares of Company Common Stock (each, a
"Certificate"), a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to a Certificate shall
pass, only upon proper delivery of a Certificate to the Exchange Agent) and
instructions for use in effecting the surrender of the Certificate and payment
therefor.  Upon surrender to the Exchange Agent of a Certificate, together with
the letter of transmittal duly executed, the holder of the Certificate shall be
entitled to receive in exchange therefor an amount equal to the product of the
number of shares of Company Common Stock represented by the Certificate
multiplied by the amount of the Merger Consideration and the Certificate shall
then be cancelled.  No interest will be paid or accrued on the cash payable upon
the surrender of the Certificate.  If payment is to be made to a person other
than a person in whose name the surrendered Certificate is registered, it shall
be a condition of payment that the Certificate so surrendered shall be properly
endorsed or otherwise in proper form for transfer and that the person requesting
payment shall pay any transfer or other taxes required by reason of the payment
to a person other than the registered holder of the surrendered Certificate or
establish to the satisfaction of the Surviving Corporation that the tax has been
paid or is not applicable.  The Exchange Agent may invest any cash deposited
with it as the Surviving Corporation directs; however, substantially all such
investments shall be in obligations of or guaranteed by the United States of
America, in commercial paper obligations receiving the highest rating from
either Moody's Investors Service, Inc. or Standard and Poor's Corporation, or in
certificates of deposit, bank repurchase agreements or bankers' acceptances of
commercial banks with capital exceeding $100,000,000 (collectively, "Permitted
Investments") or in money market funds invested solely in Permitted Investments,
and the maturities of 

                                       6
<PAGE>
 
Permitted Investments shall be such as to permit the Exchange Agent to make
prompt payment of the Merger Consideration to former stockholders of the Company
entitled thereto. Any net profit resulting from, or interest or income produced
by, Permitted Investments shall be payable to the Surviving Corporation. In the
event that at any time there shall be a net loss from such investments, the
Surviving Corporation shall immediately pay over to the Exchange Agent
additional funds in an amount sufficient to make all payments contemplated by
Section 2.2 of this Agreement. At any time after the 180th day following the
Effective Time, the Surviving Corporation shall be entitled to require the
Exchange Agent to deliver to it any funds (including any interest received with
respect thereto) that have been made available to the Exchange Agent for the
purpose of paying the Merger Consideration to holders of Company Common Stock
and that have not been disbursed to holders of Certificates, and thereafter
those holders shall be entitled to look to the Surviving Corporation (subject to
abandoned property, escheat or other similar laws) only as general creditors of
the Surviving Corporation with respect to the cash payable upon due surrender of
their Certificates. The Surviving Corporation shall pay all charges and
expenses, including those of the Exchange Agent, in connection with the exchange
of cash for shares of Company Common Stock. Until surrendered in accordance with
the provisions of this Section 2.4(b), each Certificate (other than Certificates
representing shares of Company Common Stock held by the Parent, the Sub, the
Company or any corporate affiliate of any of them and Dissenting Shares) shall
represent for all purposes the right to receive the Merger Consideration in cash
multiplied by the number of shares of Company Common Stock evidenced by that
Certificate, without any interest thereon.

          (c) From and after the Effective Time, there shall be no transfers on
the stock transfer books of the Surviving Corporation of the shares of Company
Common Stock that were outstanding immediately prior to the Effective Time.  If,
after the Effective Time, Certificates are presented to the Surviving
Corporation, they shall be cancelled and exchanged for cash as provided in this
Section 2.4.

          (d) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the Certificate to be lost, stolen or destroyed, the Surviving Corporation shall
issue in exchange for the lost, stolen or destroyed Certificate, the Merger
Consideration deliverable in respect thereof as determined in accordance with
this Section 2.  When authorizing the delivery of the Merger Consideration in
exchange therefor, the board of directors of the Surviving Corporation may, in
its discretion and as a condition to the delivery thereof, require the owner of
the lost, stolen or destroyed Certificate to give the Surviving Corporation a
bond in such sum as it may direct (not greater than the product of the number of
Shares represented by such certificate and the Merger Consideration) as
indemnity against any claim that may be made against the Surviving Corporation
with respect to the Certificate alleged to have been lost, stolen or destroyed.

     2.5  No Further Rights or Transfers.  At and after the Effective Time, the

<PAGE>
 
within one year from the date of such termination a transaction contemplated by
Subsections (a), (b) or (e) of this Section 7.1 is consummated with a Third
Person, provided (i) that such transaction is accomplished so as to provide a
yield to holders of Company Common Stock of at least the equivalent of $11.50
per share, and (ii) there was a public announcement or written proposal to
effect such transaction by or with such Third Person while this Agreement is in
effect, or (g) the board of directors of the Company withdraws or amends in any
material respect adverse to consummation of the Offer its recommendation that
the Offer be accepted by the Company's stockholders and that stockholders tender
their shares of Company Common Stock in the Offer, unless such withdrawal or
amendment results from a material breach by Parent or Sub of any representations
or warranties herein or a failure by Parent or Sub to fulfill any material
covenant herein, then the Company shall, within five days after the first of
such events has occurred, pay the Parent a fee of $1,000,000.

(subject to the fiduciary responsibility of its directors) to recommend that the
Company's stockholders accept the Offer and approve this Agreement pursuant to
Section 1.2 of this Agreement.

Company in Annex B shall expire with, and be terminated and extinguished by, the
first purchase of shares of Company Common Stock under the Offer and thereafter
the Company, the Parent and the Sub shall have no liability with respect to any
such representation or warranty.  This Section 7.2 shall have no effect upon any
other obligation of the parties, whether to be performed before or after the
first purchase of shares of Company Common Stock under the Offer.

     7.8  Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the state of Delaware, without regard to the
conflicts of laws rules of Delaware.

     7.9  Severability.  If any term, provision, covenant or restriction of this

this Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated.

     7.10  Certain Definitions.  As used herein:

          (a) "affiliate" shall have the meaning ascribed to such term in Rule
12b-2 of the General Rules and Regulations under the Exchange Act;

          (b) "Company," when used in the context of a covenant, undertaking,
representation or warranty made by the Company, unless the context otherwise
requires, shall also be deemed to be made by the Company with respect to its
subsidiaries, provided that materiality shall in all cases be measured with
respect to the Company and its subsidiaries considered as a whole.  For example,
a representation that the Company is duly incorporated shall be deemed to be a
representation that each of the Company's subsidiaries is also duly
incorporated, but the materiality of the failure of a subsidiary to be so
incorporated shall be measured with respect to the Company and its subsidiaries
taken as a whole (and not with respect to that subsidiary alone);

          (c) "Material Adverse Effect" shall mean any adverse effect on the
business, financial condition or results of operations of the Company and its
subsidiaries which is material to the Company and its subsidiaries taken as a
whole, excluding any change which generally affects the recycling industry as a
whole in the United States (such as changes in commodity prices and changes in
legal requirements); and

          (d) "subsidiary" shall mean, when used with reference to an entity,
any corporation, a majority of the outstanding voting securities of which is
owned directly or indirectly, or a majority of the board of directors of which
may be elected, by such entity.

                         AGREEMENT AND PLAN OF MERGER


          Conditions of the Offer.  Notwithstanding any other provisions of the
Offer, and in addition to (and not in limitation of) the Sub's right to amend
the Offer at any time in its sole discretion, but nevertheless subject to the
provisions of the Agreement (capitalized terms used herein and not otherwise
defined herein having the meanings ascribed to such terms in the Agreement) the
Sub shall not be required to accept for payment, or pay for, and may delay the
acceptance for payment, or the payment, of, any tendered shares of Company
Common Stock, if (i) the Minimum Condition shall not have been satisfied, or
(ii) at any time on or after the date of the Agreement and at or before the time
of payment for any such shares of Company Common Stock (whether or not any
shares of Company Common Stock have theretofore been accepted for payment or
paid for pursuant to the Offer), any of the following events shall occur:

          (a) any Material Adverse Effect shall have occurred or be threatened;
or

          (b) there shall have occurred (1) any general suspension of trading
in, or limitation on prices for, securities on the New York Stock Exchange or
the American Stock Exchange (excluding any coordinated trading halt triggered
solely as a result of a specified decrease in a market index), (2) a declaration
of a banking moratorium or any suspension of payments in respect of banks in the
United States (whether or not mandatory), (3) any material limitation (whether
or not mandatory) imposed by any governmental authority on the extension of
credit by banks or other lending institutions in the United States that
materially and adversely affects the ability of the Parent and the Sub to obtain
extensions of credit, or (4) from the date of the Agreement through the date of
termination or expiration of the Offer, a decline of at least 33% in either the
Dow Jones Average of Industrial Stocks or the Standard & Poor's 500 Index; or

          (c) any of the representations and warranties made by the Company in
the Agreement shall not be true and correct in any material respect, or the
Company shall have breached in any material respect any covenant contained in
the Agreement or the Agreement shall have been terminated in accordance with its
terms; or

          (d) there shall have been any action taken, or any statute, rule,
regulation, judgment, order or injunction promulgated, enacted, entered or
enforced, by any state, federal or foreign government or governmental authority
or by any court, domestic or foreign, that could reasonably be expected to (i)
make the acceptance for payment of, or the payment for, some or all of the
shares of Company Common Stock illegal or otherwise prohibited, (ii) impose
material limitations on the ability of the Parent or the Sub to acquire or hold
or to exercise effectively all rights of ownership of Company Common Stock,
including, without limitation, the right to vote any shares of Company Common
Stock purchased by either of them on all matters properly presented to the
stockholders of the Company, or (iii) prohibit or impose any material limitation
on the Parent's or the Sub's ownership or operation of all or a material portion

<PAGE>
 
          (e) the Company, the Parent or the Sub shall have failed to receive
any or all governmental consents and approvals to consummation of the Offer,
which, if not received, could reasonably be expected to have a Material Adverse
Effect; or

          (f) the board of directors of the Company shall have publicly
(including by amendment of its Schedule 14D-9) withdrawn or amended in any
respect its recommendation of the Offer or shall have resolved to do so, unless
such withdrawal or amendment results from a material breach by Parent or Sub of
any representations or warranties herein or a failure by Parent or Sub to
fulfill any material covenant herein.

          The foregoing conditions are for the sole benefit of the Parent and
the Sub and may be asserted by the Parent or the Sub regardless of the
circumstance giving rise to such condition and, subject to the terms of the
Agreement, may be waived by the Parent and the Sub, in whole or in part at any
time and from time to time, in their sole discretion (except that the Minimum
Condition may not be waived by the Purchaser without the consent of the
Company).  The failure by the Parent and the Sub at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right and each
such right shall be deemed an ongoing right, which may be asserted at any time
and from time to time.  Any determination by the Parent and the Sub shall be
final and binding upon all parties, including tendering stockholders.

                         AGREEMENT AND PLAN OF MERGER


          For purposes hereof, capitalized terms used herein and not otherwise
defined herein have the meanings ascribed to such terms in the Agreement.

          Any representations and warranties contained herein shall be qualified
by the contents of a writing delivered by the Company to the Parent prior to the
date of this Agreement which specifically references the Sections of this Annex
B intended to be so qualified (the "Writing").

          SECTION 1.  Corporate Existence and Power.  The Company is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation, and has all corporate powers and,
except for such the absence of which would not have a Material Adverse Effect,
all governmental licenses, authorizations, consents and approvals required to
carry on its business as now conducted.  The Company is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except for those jurisdictions
where the failure to be so qualified would not, individually or in the
aggregate, have a Material Adverse Effect.  The Company has heretofore delivered
to the Parent true and complete copies of the Company's certificate of
incorporation and by-laws as currently in effect.

          SECTION 2.  Corporate Authorization.  The execution, delivery and
performance by the Company of the Agreement and the consummation by the Company
of the transactions contemplated thereby are within the Company's corporate
powers and, except for any required approval by the Company's stockholders in
connection with the consummation of the Merger, have been duly authorized by all
necessary corporate action.   The Agreement constitutes a valid and binding
Agreement of the Company, enforceable in accordance with its terms.

          SECTION 3.  No Contravention.  The execution and delivery of the
Agreement does not, and the consummation of the transactions contemplated
thereby will not, conflict with or result in any violation of or default (with
or without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any right or obligation or to loss
of a material benefit under, any provision of the certificate of incorporation
or by-laws of the Company or any loan or credit agreement, note, bond, mortgage,
indenture, lease, or other agreement, instrument, permit, concession, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to the Company or its properties or assets, except for agreements,
contracts or instruments which do not provide for a payment to or from the
Company in excess of $100,000, or result in the creation or imposition of any
mortgage, lien, pledge, charge, security interest or encumbrance of any kind
("Lien") on any asset of the Company.  No consent, approval, order or
authorization of, or registration, declaration or filing with, any court,
administrative agency or commission or other governmental authority or

                                      B-1
<PAGE>
 
instrumentality, domestic or foreign, is required by or with respect to the
Company in connection with the execution and delivery of the Agreement by the
Company or the consummation by the Company of the transactions contemplated
thereby, except for (a) the filing of a notification and report form by or on
behalf of the Company under the HSR Act, (b) the filing with the SEC of a
Solicitation/Recommendation Statement on Schedule 14D-9 relating to the Offer
(the "Schedule 14D-9") and (c) the filing with the SEC and the distribution to
stockholders of a proxy statement relating to any meeting of the Company's
stockholders required in connection with the Merger (as that term is defined in
the Agreement) (the "Proxy Statement") or any information statement required in
connection with the Merger (the "Information Statement"), as the case may be,
(d) the filing of such other documents with, and the obtaining of such orders
from, the SEC and various state securities or "blue sky" authorities as may be
required in connection with the transactions contemplated by the Agreement, and
(e) the filing of the Certificate of Merger with the Secretary of State of the
State of Delaware.

          SECTION 4.  Capitalization.  The authorized capital stock of the
Company consists of 5,000,000 shares of Common Stock of the Company (the
"Shares") and 500,000 preferred shares.  As of March 9, 1995, there were
outstanding (i) 2,675,773 Shares, (ii) 7,813 shares of 8.25% cumulative
convertible redeemable preferred stock, no par value, convertible into an
aggregate of 6,509 Shares ("Preferred Stock"), (iii) employee and director stock
options to purchase an aggregate of 435,500 Shares (all of which options are or
by virtue of the Merger, will be exercisable), (iv) a warrant dated April 11,
1990 to purchase 113,363 Shares at an adjusted exercise price of $9.13 per
share, and (v) an option dated August 26, 1992 to purchase 25,000 Shares at an
exercise price of $3.00 per share.  All outstanding shares of capital stock of
the Company have been duly authorized and validly issued and are fully paid and
nonassessable.  Except as set forth in this Section 4 and except for changes
since March 9, 1995, resulting from the exercise of employee or other stock
options and warrants and the conversion of Preferred Stock outstanding on such
date, there are outstanding (A) no shares of capital stock or other voting
securities of the Company, (B) no securities of the Company convertible into or
exchangeable for shares of capital stock or voting securities of the Company,
and (C) no options or other rights to acquire from the Company, and no
obligation of the Company to issue, any capital stock, voting securities or
securities convertible into or exchangeable for capital stock or voting
securities of the Company (the items in clauses (i), (ii), (iii), (iv) and (v)
being referred to collectively as the "Company Securities").  There are no
outstanding obligations of the Company to repurchase, redeem or otherwise
acquire any Company Securities, other than Preferred Stock.  Except for the
subsidiaries identified in the Writing, the Company does not own any stock of
any corporation or other entity.

          SECTION 5.  SEC Filings.  (a) The Company has delivered to the Parent
(i) its annual reports on Form 10-K for its fiscal years ended December 31,
1991, 1992 and 1993, (ii) its quarterly reports on Form 10-Q for its fiscal
quarters ended March 31, June 30 and September 30, 1994, (iii) its proxy or
information statements relating to meetings of, or actions taken without a
meeting by, the stockholders of the Company held since January 1, 1991 and (iv)
all of its other reports, statements, schedules and registration statements
filed by the Company with the SEC since January 1, 1991, but including only such
pre-effective amendments to such registration statements as contain material
information not fully reflected in any subsequent 

                                      B-2
<PAGE>
 
amendment to such registration statements (or to any prospectus included
therein) delivered to the Parent pursuant to this Section 5. The Company will
file with SEC by not later than March 31, 1995 (or such later date as is in
compliance with SEC Rule 12b-25) its annual report on Form 10-K for the year
ended December 31, 1994, and deliver a copy thereof to Parent at or before such
filing.

          (b) As of its filing date, each such report or statement filed
pursuant to the Exchange Act did not (or will not) contain any untrue statement
of a material fact or omit to state any material fact necessary in order to make
the statements made therein, in light of the circumstances under which they were
made, not misleading.

          (c) Each such registration statement, as amended or supplemented if
applicable, filed pursuant to the Securities Act of 1933, as amended (the
"Securities Act"), as of the date such statement or amendment became effective,
did not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading.

          SECTION 6.  Financial Statements.  The audited consolidated financial
statements at and for the year ended December 31, 1994 delivered to the Parent
and the audited consolidated financial statements and unaudited consolidated
interim financial statements of the Company included in its annual reports on
Form 10-K and its quarterly reports on Form 10-Q referred to in Section 5 fairly
present, in conformity with generally accepted accounting principles applied on
a consistent basis, the consolidated financial position of the Company as of the
dates thereof and its consolidated results of operations and changes in
financial position or cash flows, as the case may be, for the periods then ended
(subject to normal year-end adjustments in the case of any unaudited interim
financial statements).

          SECTION 7.  Disclosure Documents.  Each document required to be filed
by the Company with the SEC in connection with the transactions contemplated by
this Agreement (the "Company Disclosure Documents") and any amendment or
supplements thereto will, when filed, comply as to form in all material respects
with the applicable requirements of the Exchange Act.

          SECTION 8.  Absence of Certain Changes.  Except for transactions
contemplated by the Agreement, since December 31, 1994 (the "Balance Sheet
Date"), the Company has conducted its business in the ordinary course consistent
with past practice and there has not been:

          (a) any event, occurrence or development of a state of circumstances

Company;

          (c) any amendment of any term of any outstanding security of the
Company;

have a Material Adverse Effect;

          (h) any transaction or commitment made, or any contract or agreement
entered into, by the Company relating to its assets or business (including the

of any contract or other right, in either case, material to the Company, other
than transactions and commitments in the ordinary course of business consistent
with past practice and those contemplated by the Agreement;

          (i) any change in any method of accounting or accounting practice by
the Company, except for any such change required by reason of a concurrent
change in generally accepted accounting principles;

          (j) other than in the ordinary course of business consistent with past

          (iii) Liens arising under financing agreements of the Company 
identified in the December Balance Sheet;

          (iv)  Statutory or common law Liens relating to obligations of the
Company that are not delinquent or are being contested in good faith;

          (v)   Purchase money security interests securing obligations of the
Company that are not delinquent for the purchase of goods in the ordinary course
of business consistent with past practice; or

          (vi)  Liens which do not materially detract from the value of such
property or assets as now used, or materially interfere with any present or
intended use of such property or assets.

          (b) No violation of any law, regulation or ordinance (including,
without limitation, laws, regulations or ordinances relating to zoning, city
planning or similar matters) relating to any of the properties or assets of the
Company exists or has existed at any time since January 1, 1989 other than for
violations which have not had and could not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect.  There are no
developments affecting any of such properties or assets pending or, to the
knowledge of the Company, threatened, which could reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect.

          SECTION 10.  No Undisclosed Material Liabilities.  There are no
material liabilities of the Company of any kind whatsoever, whether accrued,
contingent, absolute, determined, determinable or otherwise, and there is no
existing condition, situation or set of circumstances known to the Company which
could reasonably be expected to result in such a liability, other than:

          (i)   liabilities disclosed or provided for in the December Balance
Sheet;

          (ii)  liabilities incurred in the ordinary course of business
consistent with past practice since the Balance Sheet Date, which in the
aggregate are not materially greater than those reflected in the December
Balance Sheet;

          (iii) liabilities arising under or in connection with the Agreement.

          SECTION 11.  Litigation.  There is no action, suit, investigation or
proceeding (or to the Company's knowledge, any basis therefor) pending against,
or to the knowledge of the Company threatened against or affecting, the Company,
its subsidiaries or any of their properties before any court or arbitrator or
any governmental body, agency or official which, if determined 

                                      B-5
<PAGE>
 
or resolved adversely to the Company or a subsidiary, could reasonably be
expected to have a Material Adverse Effect or which in any manner challenges or
seeks to prevent, enjoin, alter or materially delay the Offer or Merger or any
of the other transactions contemplated hereby.

          SECTION 12.  Taxes.  The Company and its subsidiaries have filed all
federal income and other tax returns required to be filed by any of them and
have paid (or the Company has paid on behalf of its subsidiaries), or have set
up an adequate reserve (in accordance with generally accepted accounting
principles) for the payment of, all taxes shown to be due on such returns and
the December Balance Sheet reflects an adequate reserve for all taxes payable by
the Company accrued through December 31, 1994.  The Company is not delinquent in
the payment of any material tax, assessment or governmental charge.  No material
deficiencies for any taxes have been proposed, asserted or assessed in writing
against the Company or its subsidiaries.  For the purposes of this Agreement,
the term "tax" shall include all federal, state, local and foreign income,
property, sales, excise and other taxes of any nature whatsoever.  Neither the
Company nor any member of any affiliated or combined group of which the Company
is or has been a member has granted any extension or waiver of the limitation
period applicable to any tax returns.  There are no Liens for taxes upon the
assets of the Company, except Liens for current taxes not yet due.  The Company
will not be required under Section 481(c) of the Internal Revenue Code of 1986,
as amended (the "Code"), to include any adjustment in taxable income for any
period subsequent to the Merger.  The Company has delivered to the Parent copies
of its federal, state and local income and franchise tax returns for the years
ended December 31, 1991, 1992 and 1993.  The Company has not been a United
States real property holding corporation within the meaning of Code Sec.
897(c)(2) during the applicable period specified in Code Sec. 897(c)(1)(A)(ii).
Each of the Company and its subsidiaries has disclosed on its federal income tax
returns all positions taken therein that could give rise to a substantial
understatement of federal income tax within the meaning of Code Sec. 6662.  None
of the Company or its subsidiaries is a party to any tax allocation or sharing
agreement.  None of the Company or its subsidiaries (A) has been a member of an
affiliated group filing a consolidated federal income tax return (other than a
group the common parent of which was the Company or a subsidiary of the Company)
or (B) has any liability for the taxes of any person (other than any of the
Company and its subsidiaries) under Treas. Reg. (S) 1.1502-6 (or any similar
provision of state, local, or foreign law), as a transferee or successor, by
contract, or otherwise.

          SECTION 13.  ERISA.  (a)  The Writing identifies each "employee
benefit plan," as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), which (i) is subject to any
provision of ERISA, (ii) is maintained, administered or contributed to by the
Company or any affiliate (as defined below) and (iii) covers any employee or
former employee of the Company or any affiliate or under which the Company or
any affiliate has any liability.  Copies of such plans (and, if applicable,
related trust agreements) and all amendments thereto and any written
interpretations thereof have been furnished to the Parent together, if
applicable, with (x) the three most recent annual reports (Form 5500 including,
if applicable, Schedule B thereto) prepared in connection with any such plan and
(y) the most recent actuarial valuation report prepared in connection with any
such plan.  Such plans are referred to collectively herein as the "Employee
Plans."  For purposes of this Section, "affiliate" of any Person means any other
Person which, together with such Person, would be treated as a 

                                      B-6
<PAGE>
 
single employer under Section 414 of the Code. For purposes of this Annex B,
"Person" means any individual, corporation, partnership, association, trust, or
other entity or organization, including a governmental or political subdivision
or an agency or institution thereof.

          (b) There are no Employee Plans subject to Title IV of ERISA, other
than multiemployer plans as defined in Section 4001(a)(3) of ERISA
("Multiemployer Plans").  The Company has provided the Parent with a list of all
Multiemployer Plans to which the Company or any active subsidiary presently has
any obligation to contribute.  Neither the Company nor any affiliate has any
outstanding liability to any Multiemployer Plan for delinquent contributions, or
for withdrawal liability pursuant to Section 4201 of ERISA.

          (c) There are no Employee Plans which are intended to be qualified
under Section 401(a) of the Code.  Each Employee Plan has been maintained in all
material respects in compliance with its terms and with the requirements
prescribed by any and all statutes, orders, rules and regulations, which are
applicable to such Plan.

          (d) There is no contract, agreement, plan or arrangement covering any
employee or former employee of the Company or any affiliate that, individually
or collectively, could give rise to the payment of any amounts that would not be
deductible pursuant to the provisions of Section 280G of the Code.

          (e) The Writing contains a list of each employment, severance or other
similar contract, arrangement or policy and each plan or arrangement (written or
oral) providing for insurance coverage (including any self-insured
arrangements), workers' compensation, disability benefits, supplemental
unemployment benefits, vacation benefits, retirement benefits or for deferred
compensation, profit-sharing, bonuses, stock options, stock appreciation rights
or other forms of incentive compensation or post-retirement insurance,
compensation or benefits which (i) is not an Employee Plan, (ii) is entered
into, maintained or contributed to, as the case may be, by the Company or any of
its affiliates and (iii) covers any employee or former employee of the Company
or any of its affiliates.  Such contracts, plans and arrangements as are
described above, copies or descriptions of all of which have been furnished
previously to the Parent, are referred to collectively herein as the "Benefit
Arrangements."  Each Benefit Arrangement has been maintained in substantial
compliance with its terms and with the requirements prescribed by any and all
statutes, orders, rules and regulations that are applicable to such Benefit
Arrangement.

          (f) Neither the Company nor any affiliate has or maintains or has
maintained any Employee Plan or Benefit Arrangement providing post-retirement
health or medical benefits in respect of any active or former employee of the
Company or any affiliate or former affiliate.

          (g) There has been no amendment to, written interpretation or
announcement (whether or not written) by the Company or any of its affiliates
relating to, or change in employee participation or coverage under, any Employee
Plan or Benefit Arrangement which would increase materially the expense of
maintaining such Employee Plan or Benefit Arrangement above the level of the
expense incurred in respect thereof for the fiscal year ended on the Balance
Sheet Date.

                                      B-7

          (h) The Company is not a party to or subject to any union contract or
any express employment contract or arrangement providing for annual future
compensation of, or benefits or other similar payments to, any officer,
consultant, director or employee in excess of $50,000.

          SECTION 14.  Material Contracts.  (a)  Except for agreements,
contracts, plans, leases, arrangements or commitments disclosed in the Company's
SEC filings referred to in Section 5 or as previously disclosed in the Writing,

          (i)    any lease relating to real property or any other lease 
providing for annual rentals in excess of $100,000;

          (ii)   any agreement for the purchase of materials, supplies, goods,
services, equipment or other assets providing for annual payments by the Company

with past practice;

          (iii)  any sales, distribution or other similar agreement providing

or other assets that provides for annual payments to the Company in excess of
$100,000, other than in the ordinary course of business consistent with past
practice;

          (iv)   any partnership, joint venture, or other similar contract,
arrangement or agreement;

          (v)    any contract relating to indebtedness for borrowed money or the
deferred purchase price of property (whether incurred, assumed, guaranteed or
secured by any asset) in excess of $100,000, except in the ordinary course of
business consistent with past practice;

          (vi)   any license agreements, franchise agreements or agreements in
respect of similar rights granted to or held by the Company;

          (vii)  any agency, dealer, sales representative or other similar 
agreement;

          (viii) any contract or other document that substantially limits the
freedom of the Company to compete in any line of business or with any Person or
in any area or which would so limit the freedom of the Company after the
Effective Time (as that term is defined in the Agreement); or

          (ix)   any other contract or commitment not made in the ordinary 
course of business which is material to the Company.

          (b) All agreements, contracts, plans, leases, arrangements and
commitments disclosed in the Company's SEC filings referred to in Section 5 or
disclosed or required to be disclosed pursuant to this Annex (the "Material
Contracts") are valid and binding agreements of the Company, are in full force
and effect, and neither the Company nor, to the knowledge of the

                                      B-8

Company, any other party thereto is in default in any respect under the terms of
any such agreement, contract, plan, lease, arrangement or commitment, except, in
all cases, such as could not reasonably be expected to have a Material Adverse
Effect.

          SECTION 15.  Insurance Coverage.  The Company has made available to
the Parent true and complete copies of, all insurance policies and fidelity
bonds covering the assets, business, equipment, properties, operations,
employees, officers and directors of the Company.  There is no claim by the
Company pending under any of such policies or bonds as to which coverage has
been questioned, denied or disputed by the underwriters of such policies or
bonds.  All premiums due and payable under all such policies and bonds have been
paid and the Company is otherwise in full compliance with the terms and
conditions of all such policies and bonds.  Such policies of insurance and bonds
(or other policies and bonds providing substantially similar insurance coverage)
are in full force and effect.  Except as previously disclosed by the Company to
the Parent in writing, the Company does not know of any threatened termination
of, or premium increase with respect to, any of such policies or bonds.

          SECTION 16.  Compliance with Laws.  The Company is not in violation
of, and has not materially violated, any applicable provisions of any laws,
statutes, ordinances or regulations material to the conduct of the business of
the Company as currently conducted, except in all cases, such as could not
reasonably be expected to have a Material Adverse Effect.

          SECTION 17.  Investment Banking Fees.  There is no investment banker,
broker, finder or other similar intermediary which has been retained by, or is
authorized by, the Company to act on behalf of the Company who might be entitled
to any fee or commission from the Company, the Parent and the Sub or any of
their respective affiliates upon consummation of the transactions contemplated
by this Agreement, except Allen & Company Incorporated and Guilford Securities,
Inc.  Copies of the Company's agreements with these firms have been furnished to
Parent.

          SECTION 18.  Intellectual Property.  (a)  The Company has listed in
the Writing all inventions which are the subject of issued letters patent or an
application therefor, all trade and service marks which have been registered or
for which an application for registration is pending and all writings for which

nature of such Intellectual Property Right; (ii) the owner of such Intellectual
Property Right; (iii) the jurisdictions by or in which such Intellectual
Property Right has been issued or registered or in which an application for such
issuance or registration has been filed, including the respective registration

<PAGE>
 
          (b) The Company holds all licenses for Intellectual Property Rights
owned by another Person materially necessary to the conduct of its business as
currently conducted, except such as could not reasonably be expected to have a
Material Adverse Effect.

          (c) The Company (i) during the three years preceding the date of this
Agreement has not been sued or charged in writing with or been a defendant in
any claim, suit, action or proceeding relating to its business which has not
been finally terminated prior to the date hereof and which involves a claim of
infringement of any patents, trademarks, service marks or copyrights, (ii) has
no knowledge of any other claim or infringement by the Company or (iii) has no
knowledge of any continuing infringement by any other Person of any Intellectual
Property Rights.  No Intellectual Property Right is subject to any outstanding
order, judgment, decree, stipulation or agreement restricting the use thereof by
the Company or restricting the licensing thereof by the Company to any Person.
The Company has not entered into any agreement to indemnify any other Person
against any charge of infringement of any patent, trademark, service mark or
copyright.

          SECTION 19.  Environmental Compliance.  Except in all cases as in the
aggregate have not had and could not reasonably be expected to have a Material
Adverse Effect, the Company and each of its subsidiaries (i) have obtained all
permits, licenses and other authorizations which are required under Federal,
state or local laws relating to pollution or protection of the environment,
including laws relating to emissions, discharges, releases or threatened
releases of pollutants, contaminants, or hazardous or toxic materials or wastes
into ambient air, surface water, ground water, or land or otherwise relating to
the manufacture, processing, distribution, use, treatment, storage, disposal,
transport, or handling of pollutants, contaminants or hazardous or toxic
materials or wastes; (ii) are in compliance with all terms and conditions of
such required permits, licenses and authorizations, and also are in compliance
with other limitations, restrictions, conditions, standards, prohibitions,
requirements, obligations, schedules and timetables contained in such laws or
contained in any regulation, code, order, decree or judgment, issued, entered or
promulgated thereunder; (iii) as of the date of the Agreement, are not aware of
nor have received notice of any event, condition, circumstance, activity,
practice, incident, action or plan which is reasonably likely to interfere with
or prevent continued compliance or which would give rise to any common law or
statutory liability, or otherwise form the basis of any claim, action, suit or
proceeding, based on or resulting from the Company's or any of its subsidiary's
manufacture, processing, distribution, use, treatment, storage, disposal,
transport, or handling, or the emission, discharge, or release into the
environment, of any pollutant, contaminant, or hazardous or toxic material or
waste; and (iv) have taken all actions necessary under applicable requirements

(ii), insofar as it relates to the Company, the Offer, will contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading.

          SECTION 21.  Delaware Corporation Law, etc.  The board of directors of
the Company has unanimously approved the Offer, the Merger, the agreements of
any stockholders to tender Shares (the "Stock Tender Agreements") and the
consummation of the transactions contemplated hereby and thereby and such
approval is sufficient to render inapplicable the prohibitions of Section 203 of
the General Corporation Law of the State of Delaware with respect to the Offer
and the Merger.  To the best of the Company's knowledge, no other state takeover
statute applies to the Offer, the Merger or the Stock Tender Agreements (and the
Company covenants to use all reasonable efforts to take all action necessary to
ensure that the same are inapplicable to the Offer, the Merger and the Stock
Tender Agreements and the transactions contemplated thereby).

          SECTION 22.  Real Estate.  Except as disclosed in the Writing,

          (a) The real estate owned ("Real Estate") or leased (the "Leasehold
Premises") by the Company is as described in the Company's Annual Report on Form
10-K for the year ended December 31, 1993.

          (b) The buildings located on the Real Estate and the Leasehold
Premises are each in good operating condition, normal wear, tear and maintenance
down-time excepted, and are in the aggregate sufficient to satisfy the Company's
current operating levels.

          (c) Each parcel of the Real Estate and the Leasehold Premises:  (i)
has direct access to public roads or access to public roads by means of a
perpetual access easement, such access being sufficient to satisfy the current
and reasonably anticipated normal transportation requirements of the Company's
business as presently conducted at such parcel; and (ii) is served by all
utilities, including but not limited to water, electricity, natural gas, sewer
and telephone, in such quantity and quality as are sufficient to satisfy the
current normal production levels and business activities of the Company's
business as conducted at such parcel.

          (d) The Company has received no notice of:  (i) any condemnation
proceeding with respect to any portion of the Real Estate or the Leasehold
Premises, and to the best of its knowledge no proceeding is contemplated by any
governmental authority; or (ii) any special assessment which may affect the Real
Estate or the Leasehold Premises, and to the best of its knowledge no such
special assessment is contemplated by any governmental authority.

Allen & Company Incorporated, a New York corporation (the "Stockholder"), Waste
Management, Inc., an Illinois corporation ("Parent") and WMI Acquisition Sub,
Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Buyer").

     WHEREAS, Buyer, and Resource Recycling Technologies, Inc., a Delaware

Merger dated the date hereof (the "Acquisition Agreement") which provides, among
other things, that Buyer shall commence an all cash tender offer to purchase any
and all shares of common stock of the Company at a purchase price of $11.50 per
share (the "Offer", which term shall include any amendment thereof not in
violation of the Acquisition Agreement), to purchase any and all of the issued
and outstanding shares of Company's Common Stock, par value $1.00 per share
("Common Stock"), and shall merge Buyer with and into the Company (the
"Merger"), in each case upon the terms and subject to the conditions set forth
in the Acquisition Agreement (any term used herein without definition shall have
the definition ascribed thereto in the Acquisition Agreement);

     WHEREAS, as of the date hereof, the Stockholder beneficially owns 664,806
shares of Common Stock (the "Stockholder's Shares");

     WHEREAS, as a condition to the willingness of the Company and Buyer to
enter into the Acquisition Agreement, and as an inducement to them to do so, the
Stockholder has agreed for the benefit of the Company and Buyer to tender the
Stockholder's Shares, and any other shares of Common Stock at any time during
the term of this Agreement held by Stockholder, in response to the Offer on the
terms and conditions contained in this Agreement; and

     WHEREAS, the Board of Directors of the Company has approved the Acquisition
Agreement, the Offer, the Merger and this Agreement.

     NOW THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement the parties hereby agree as
follows:

                                   ARTICLE 1

                                 TENDER OFFER

     SECTION 1.1.  Tender of Shares.  (a) Within five (5) business days of the
commencement by the Buyer of the Offer the Stockholder shall tender to the
depositary (the "Depositary") designated in the Offer to Purchase (the "Offer to
Purchase") distributed by the Buyer in connection with the Offer (i) a letter of
transmittal with respect to the Stockholder's Shares and any other shares of
Common Stock held by the Stockholder (such shares being referred to herein as
the "Shares"), complying with the terms of the Offer to Purchase, together 

<PAGE>
 
with instructions directing the Depositary to make payment for such Shares
directly to the Stockholder (but if such Shares are not accepted for payment and
are to be returned pursuant to the Offer to Purchase, to return such Shares to
Stockholder), (ii) the certificates representing the Shares and/or (iii) all
other documents or instruments required to be delivered pursuant to the terms of
the Offer to Purchase (such documents in clauses (i) through (iii) collectively
being hereinafter referred to as the "Tender Documents").

          (b) The Stockholder will not, subject to applicable law, withdraw the
tender effected in accordance with Section 1.1.(a); provided, however, that the
Stockholder may decline to tender, or may withdraw, any and all Shares if (A)
the amount or form of consideration to be paid for such Shares is less than cash
in the amount of $11.50 per Share, net to the Stockholder in cash, (B) the
Acquisition Agreement is terminated, or (C) the Board of Directors of the
Company has withdrawn its recommendation of the Offer pursuant to Section
6.1(c)(ii) of the Acquisition Agreement, provided that if such withdrawal of a
recommendation occurs and the Board of Directors subsequently recommends an
offer by Buyer or an affiliate of Buyer for a consideration per Share greater
than $11.50 per Share, the Stockholder agrees to re-tender any Shares it has
withdrawn, whereupon all the terms of this Agreement shall be revived and
applicable to such Shares.

the Stockholder after the date hereof and prior to the termination of this
Agreement, whether upon the exercise of options or by means of purchase,
distribution, dividend or otherwise, shall be immediately tendered by the
Stockholder and shall constitute "Shares" subject to the terms of this
Agreement.

     SECTION 1.3.  No Purchase.  Buyer may allow the Offer to expire without
accepting for payment or paying for any Shares, as set forth in the Offer to
Purchase, without purchasing all or any Shares pursuant thereto.  If any Shares

Purchase, they shall be returned to Stockholder, whereupon they shall continue
to be held by Stockholder subject to the terms and conditions of this Agreement.

     SECTION 1.4.  Restrictions.  Except as contemplated by Section 1.1 hereof
and so long as the Board of Directors of the Company has not withdrawn its
recommendation of the Offer pursuant to Section 6.1(c)(ii) of the Acquisition
Agreement, Stockholder shall not, directly or indirectly: (i) offer for sale,
sell, transfer, tender, pledge, encumber, assign or otherwise dispose of, or

any party other than Buyer or an affiliate of Buyer to acquire or offer to
acquire the Company, any of its Common Stock or a material portion of the assets
or business of the Company or any of its subsidiaries.
