A report released by the Joint Legislative Commission on Toxic Substances and Hazardous Wastes concludes that carefully controlled, high-temperature incineration of hazardous wastes in cement and lightweight aggregate kilns is one of the most promising options currently available for destroying many of these wastes. The types of hazardous wastes that can be burned in cement kilns include: used solvents produced by metalworking, painting, cleaning and printing processes; petroleum industry wastes; off specification chemical products; and waste oils, such as used automotive oil. According to the report, cement kilns have several characteristics that make them a desirable technology for burning hazardous wastes. Combustion temperatures and gas residence times are higher than those generally experienced in conventional hazardous waste incinerators. Conditions within the kiln must be carefully monitored to ensure that the high temperatures necessary to produce cement are maintained. Also, because limestone is a primary ingredient in cement, alkaline conditions within the kiln virtually eliminate air emissions of hydrogen chloride, a precursor to acid rain. Additionally, the energy recovered through the burning of chemical wastes as a fuel substitute could result in a measurable reduction in New York's total industrial energy consumption.
