Abstract
ABSTRACT
About 1.5 billion gallons of hazardous waste solvents were disposed of to the land in 1985. The Hazardous and Solid Waste Amendments (HSWA) of 1984 required that EPA prohibit the direct land disposal of these materials after November 8, 1986. Alternatives to direct land disposal include source reduction, destruction, treatment, and recovery. This paper describes several technologies that can be used to recover solvent materials from hazardous wastes. Such technologies include evaporation, distillation, solvent extraction, critical fluids processing, steam and air stripping, and carbon adsorption. Data from USEPA studies are presented on recovery efficiencies for several of the unit processes.
