BOCA RATON, Fla.--(BUSINESS WIRE)--Aug. 31, 2000

U.S. Plastic Lumber Corp. (Nasdaq:USPL), announced today that its wholly owned subsidiary, Clean Earth Inc., ("CEI"), an environmental services company, was awarded new contracts totaling approximately $23 million.

Clean Earth, Inc., through the combined efforts of its subsidiaries Barbella Environmental Technology, Inc., ("BET"), Somerville, NJ and Integrated Technical Services, Inc., ("ITS"), Winslow, NJ, was awarded several significant projects involving the use of CEI's technologies and experience.

Barbella Environmental Technology, Inc. was awarded a $9 million contract from the Cumberland County Landfill Development Authority for the construction of three new double-lined landfill cells and the related work for leachate management facilities; including a collection conveyance system, pump buildings, and force main construction. The new cells will provide an additional 26 acres of landfill space to serve Cumberland County, NJ. BET was also awarded a $7 million project from the Hackensack Meadowlands Development Commission ("HMDC") to construct perimeter closure improvements including sedimentation ponds, outlet structures, and perimeter ditches and berms. The closure operation will allow HMDC to continue their program of "returning previously used property to the community" by providing a native habitat, hiking trails, and open space. BET was also awarded approximately $2 million of contract change orders on existing contracts and several new smaller projects.

BET performs infrastructure and brownfield renewal projects involving heavy civil and environmental construction methods, including landfill construction and capping, water treatment plants and geo-environmental installations.

Integrated Technical Services (ITS) was awarded new contracts totaling approximately $5 million, which include landfill construction projects in Maryland and Delaware, and a project for remediation services at the Letterkenny Army Depot. ITS provides specialty site treatment and innovative technology services for the remediation of environmentally distressed sites.

Consolidated Technologies, Inc. (CTI), also a CEI subsidiary, has completed a $2 million initial project at the Claremont Dredge Material Recycling Port Facility (DMRF). This project, which has been previously announced by USPL, represented the start-up project for the facility and was performed for the New York Department of Sanitation. The work involved the removal of contaminated sediment by dredge, transport by barge to the DMRF facility for process treatment and subsequent shipment as recyclable fill for the remediation and reclamation of Pennsylvania strip mines. In July, CTI started their second project for the Port Authority of New York and New Jersey. This $11.5 million project, which was also previously announced, involves similar dredging efforts wherein CTI will process 200,000 cubic yards of contaminated dredge for ultimate reclamation of a Pennsylvania strip mine.

CTI provides environmental recycling and beneficial re-use services primarily related to the treatment, processing and beneficial re-use of clean and environmentally impacted dredge materials for a variety of upland uses.

Frank Barbella, President of Clean Earth, Inc., said, "CEI's expertise in the beneficial re-use technology and our fixed base treatment facilities are the core ingredient for our success in obtaining these new business contracts for the remainder of this year and 2001. The start-up at the Claremont Facility, despite some early setbacks, is now progressing toward capacity and solidifies our position for significant future opportunities in the dredge re-use market. These developments and the near capacity volumes at our other Clean Earth treatment facilities are indicative of an extremely productive and successful year."

USPL also reported that recent rankings for the "Top 200 Environmental Firms" by the industry standard "Engineering News-Record" (ENR), cited Clean Earth, Inc. as number 18 in the top "All Environmental Firms", based upon 1999 revenues and Barbella Environmental Technology, Inc., as number 14 in the Solid Waste category.
