     Re:  REGISTRATION STATEMENT ON FORM S-4

Dear Ladies and Gentlemen:

     This opinion is furnished to you in connection with a Registration
Statement on Form S-4 (the "Registration Statement") filed with the
Securities and Exchange Commission (the "Commission") relating to the
registration under the Securities Act of 1933, as amended (the "Securities
Act"), of the issuance and exchange of up to $150,000,000 original principal
amount of 9.75% Senior Subordinated Notes Due 2013 (the "New Notes"), of
Casella Waste Systems, Inc., a Delaware corporation (the "Company"), and the
guarantees of the obligations represented by the New Notes (the "Guarantees"
and, together with the New Notes, the "Securities") by certain subsidiaries
of the Company (such entities, collectively, the "Guarantors").

     The Securities are to be issued pursuant to an Indenture, dated as of
January 24, 2003, as supplemented and amended from time to time (the
"Indenture"), among the Company, the Guarantors and U.S. Bank National
Association, as trustee (the "Trustee"). The Securities are to be issued in an
exchange offer (the "Exchange Offer") for a like aggregate original principal
amount of 9.75% Senior Subordinated Notes Due 2013 currently outstanding (the
"Old Notes") in accordance with the terms of an Exchange and Registration Rights
Agreement, dated as of January 21, 2003 (the "Registration Rights Agreement"),
by and among the Company, the Guarantors and the Purchasers (as defined
therein), which is filed as Exhibit 4.2 to the Registration Statement.

     Solely for the purpose of furnishing this opinion, we are acting as
special counsel for KTI, Inc. and KTI Environmental Group, Inc., each a New
Jersey corporation (the "New Jersey Guarantors"), Casella Waste Management of
Pennsylvania, Inc., a Pennsylvania corporation (the "Pennsylvania Guarantor")
and North Country Environmental Services, Inc., a Virginia corporation (the
"Virginia Guarantor"), in connection with the issuance by the New Jersey
Guarantors, the Pennsylvania Guarantor and the Virginia Guarantor of the
Guarantees. We have examined signed copies of the Registration Statement as
filed with the Commission. We have also examined and relied upon the
Registration Rights Agreement, the Indenture, resolutions adopted by the
board of directors of each of the New Jersey Guarantors, the Pennsylvania
Guarantor and the Virginia Guarantor, as provided to us by
