Impact/Purpose:

Demonstrate the feasibility of environmentally and cost-effectively decontaminating dredged material from NY/NJ Harbor with using the post-treated material for beneficial use. Beneficial use products are manufactured soil, construction-grade cement, light-weight aggregate, architectural tiles, and composite bricks. Once sediments are decontaminated, these beneficial use products could be used for the restoration and re-development of impacted regions/communities adjacent to impacted waterways such as the Passaic River, NJ and Gowanus Canal, NY.

Description:

Thermal and non-thermal decontamination technologies have been undergoing demonstrations at the bench through full/commercial-scale levels. The decontamination program is being conducted under the auspices of the Water Resources Development Acts (92, 96) working in conjunction with the U.S. Dept.of Energy Brookhaven National Laboratory, the NJ Department of Transportation, and the EPA SITE Program. The program utilizes a treatment train concept looking at materials handling (including facility siting and permitting), decontamination and beneficial use of post-treated material. The Biogenesis sediment washing process has undergone pilot-scale testing in 2000 (Kearny,NJ), further pilot-scale testing in the Port of Venice, Italy (2004) and full/commercial scale demonstration in 2006 utilizing a 250,000 cy/yr processing facility constructed at Bayshore Recycling, Inc located in Keasby, NJ. In collaboration with the NJ Maritime Resources/DOT Sediment Decontamination Program approximately 20,000 cy of navigational dredged material was processed. Furthermore, working with NJ OMR and the EPA Superfund Passaic River Restoration Study, approximately 5,000 cy of Superfund Passaic River sediment was dredged in December of 2005 and delivered to Bayshore Recycling for decontamination demonstration utilizing the Biogenesis sediment washing process and the Gas Technology Institute/Endesco thermal-chemical rotary demonstration kiln located in Bayonne, NJ. BioGenesis completed processing of the navigational dredged material and the Passaic River sediment in May 2006. A final report is expected in January 2007. GTI will commence processing of the dewatered Passaic River sediment in early November 2006 with project completion by December 2006. A final report is expected by March 2007. The EPA Sediment Decontamination Program is also working with the USACE New England Division, the CT Department of Environmental Protection, and the Bridgeport CT Port Authority in developing a decontamination program with beneficial use applications for Bridgeport Harbor and Long Island Sound embayments. Fifty (50) cy of Biogenesis decontaminated sediment will be shipped to the Port of Bridgeport in October 2006 for blending of manufactured soil.
