Minergy GFT Supplemental Sediment

The purpose of the Study is to evaluate the economic and technical feasibility of melting PCB contaminated river sediments in a glass furnace. The Glass Furnace Technology (GFT) was developed by Minergy. Minergy originally developed vitrification technologies to process wastewater sludge into glass aggregate that could be sold as a commercial product. The technology was evaluated during a U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation (SITE) Program demonstration at the Minergy facility in Winneconne, Wisconsin, in August 2001. The SITE program evaluated the technology's ability to treat sediment containing PCBs and mercury. Because the GFT process requires the river sediment to be greater than 90 percent solids prior to loading into the melter, the SITE program also evaluated a bench-scale dryer technology as a secondary activity. The sediment for this
evaluation was dredged from the Lower Fox River, dewatered, and filter pressed.
