SITE Demonstration of Minergy Glass Furnace Treatment of PCBs, PCDDs/Fs, and Metals in River Sediment

Abstract

The U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation (SITE) program selected the Glass Furnace Technology (GFT) treatment process for evaluation. The GFT was developed by Minergy Corporation as an ex situ remediation technology to treat river sediment contaminated with polychlorinated biphenyls (PCBs), other organic compounds, and metals. The pilot-scale demonstration of the GFT was conducted at Minergy’s GlassPack Test Center facility in Winneconne, Wisconsin. In the GFT treatment, dewatered sediment is dried, flux is added to control melting temperatures and improve the physical properties of the glass aggregate product, and then the sediment and flux mixture is melted at a temperature of about
