A full-scale technology demonstration of a polyethylene encapsulation process, sponsored by the U.S. Department of Energy (DOE) Office of Technology Development, was held at the Environmental and Waste Technology Center at Brookhaven National Laboratory (BNL) in September 1994. Polyethylene encapsulation has been developed and tested at BNL as an alternative solidification technology for improved treatment of low-level radioactive (LLW), hazardous, and mixed wastes. Although originally developed for treatment of DOE-generated wastes through waste management and environmental restoration activities, polyethylene encapsulation has application within the commercial sector. A fully equipped, production-scale system, capable of processing over 900 kg/hr (2000 lb/hr), has been installed at BNL. The demonstration covered all facets of the integrated processing system including pre-treatment of aqueous wastes, precise feed metering, extrusion processing, on-line quality control monitoring, and process control. Following the demonstration, waste-form testing was conducted to confirm performance of the final waste form. 10 refs., 5 figs., 1 tab.
