ABSTRACT:
A method and system for detoxify hazardous waste is described. The waste is mechanically particularized to a predetermined particle size and is then subjected to a gas flow having a temperature between 250.degree. C. and 750.degree. C. At the same time, the particularized waste is agitated to enhance its exposure to the gals flow, resulting in gasification of a substantial portion of the solid waste. The remaining particularized waste residue is collected for recycling of further disposal. After passing through the agitated particularized waste, the gas flow is circulated to a thermolytic detoxification reactor and then recirculated to the agitated particularized waste.
