Abstract
Method and apparatus for isolating, decomposing, and fixing the organic hazardous substances in a stable manner using chemical techniques and isolating and decomposing the organic hazardous substances from various waste mixtures. The temperature treatment is preferably kept within room temperature range of between 0-30° C. The detoxification of the organic hazardous substances avoids secondary pollution of the environment when the treated materials are released in the soil, atmosphere, or in groundwater.
