Application of the supercritical water oxidation for the treatment of hazardous materials is regarded as one of the promising techniques for the purpose of the environmental protection. Organic as well as inorganic compounds including dioxines of PCBs are completely decomposed in a very short reaction time into nonhazardous compounds. It is attempted, in the present project, to establish the fundamental methodology for removing toxic substances in the process of waste disposal treatment by applying supercritical water oxidation technique.
