FOR IMMEDIATE RELEASE

                  KTI ANNOUNCES COOPERATIVE VENTURE TO DEVELOP
               FORD HEIGHTS RECYCLING AND TIRE-RELATED BUSINESSES


         GUTTENBERG, N.J. (DEC. 31, 1998) KTI, Inc. (NASDAQ: KTIE) and Oakhurst
Company, Inc., (OTC Bulletin Board: OAKC) today announced the formation of a
cooperative venture to develop tire processing and recycling businesses.

         As part of the transaction, KTI acquired, in a private placement,
1,730,000 shares in Oakhurst (representing a 35% stake) at a cost of $865,000,
and has also entered into a secured loan agreement to lend Oakhurst up to $17
million. The funds will be invested in Oakhurst's wholly-owned subsidiary,
Oakhurst Technology, Inc. ("OTI"), which has been designated by KTI to develop
both the environmental facility in Fords Heights, IL, and other tire-recycling
and related businesses.

         In addition, a subsidiary of KTI has agreed to license to OTI a
proprietary cryogenic crumb rubber technology for use in other projects in the
United States. The agreement provides for the purchase of crumb rubber systems
by OTI from the subsidiary, together with a royalty agreement between them
relating to tires processed by such equipment. Another KTI subsidiary will be
the operating manager of New Heights, and will also operate any related
facilities to be acquired by OTI in the future. Oakhurst has agreed to appoint
three KTI nominees to its Board, and two KTI nominees to the Board of OTI.

         In return for its investment in upgrading and retrofitting the Ford
Heights operation, OTI will acquire a 50% equity interest in the entity that
owns the facility, New Heights Recovery and Power, LLC ("New Heights"). OTI
expects that over time, subject to the receipt of the necessary permits, New
Heights will be developed as an environmental campus for the processing and
recycling of paper and other non-hazardous wastes in addition to the manufacture
of crumb rubber. New Heights may employ up to 350 people from the Ford Heights
community.

         Commenting on the transaction, KTI President, Martin Sergi said, "The
venture with Oakhurst provides both companies with strategic benefits. In
addition to the equity investment in Oakhurst, the arrangement provides KTI with
royalty income, management fees, profits on the

sale of crumb rubber equipment and interest income. Oakhurst's management team
will bring invaluable experience to the development of OTI's business, involving
acquisitions and restructurings in the tire-recycling business and the emerging
crumb rubber industry, while KTI's management expertise will help ensure
superior operating results of the acquired businesses".

         Oakhurst, a holding company, owns two businesses which are distributors
in the automotive aftermarket.

         KTI is an integrated solid waste management operating 51 facilities in
21 states and Canada in four operating divisions, Waste to Energy, Finished
Products, Commercial Recycling and Residential Recycling.
