DNR contracted with Minergy Corporation (Minergy) to investigate thermal treatment technology alternatives for Fox River site sediment remediation. Based on an initial study of sediment physical and chemical properties, Minergy recommended vitrification of the sediment in an oxyfuel fired glass furnace (Glass Furnace Technology or GFT). In cooperation with DNR and EPA’s Superfund Innovative Technology Evaluation (SITE) group, Minergy has completed
bench-scale and pilot-scale testing of the GFT process and the results are favorable. In general, completed studies have demonstrated that the PCB contaminated river sediment can be successfully converted into a vitrified glass aggregate product meeting ASTM specifications for blended cements. The process and environmental performance data generated during the pilotscale test also indicate that a commercial-scale GFT application is feasible.
Minergy was contracted by DNR to perform a review of relevant state and federal permitting requirements for a full scale sediment melter facility. The results of that study are presented in this report.
