Some attractive alternatives to hazardous waste incineration which make use of a waste's heat content are cofiring of hazardous wastes in high temperature industrial processes. Many such processes, which include cement and dolomite kilms, glass furnaces, steel furnaces, and some industrial boilers, provide conditions of temperature and residence time similar to those required for dedicated hazardous waste incinerators. In addition to the savings derived from the heat value, the use of existing industrial processes requires less capital to process a given amount of hazardous waste. The ability of a cement kiln to destroy wastes was evaluated. Data was collected to formulate permitting criteria, and to evaluate the kiln's ability to remove the HCl combustion product. A sampling program was conducted during the burning of the hazardous waste. The primary goal of the program was to evaluate the effects of various waste parameters on the destruction efficiency of Principal Organic Hazardous Components (POHC's), and change in emissions of particulate matter, hydrocarbons, CO, SO sub 2 , NO/sub x/, and HCl. Secondary objectives were to detect and quantify the Products of Incomplete Combustion (PIC's), chlorinated dibenzofurans, chlorinated dibenzodioxins, trace metals and heavy organics. Results show lower destruction and removal efficiencies, no change in particulate emissions, and significant changes in SO sub 2 and NO/sub x/ emissions. (ERA citation 08:039346)
