A melting furnace that incorporates the autoclave theory and is equipped with a high-frequency (horizontal wave) device for incinerating material and for thermal decomposition and recrystallization of organic and inorganic hazardous compounds contained in it and to detoxify hazardous substances that have been recrystallized or thermally decomposed by using specific solvents. A method to accomplish the above is provided and hazardous gas that is generated during the incineration process at high temperature and under high pressure in the furnace is treated.
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.degree. 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.
Waste plastics, which contain coloring agents and are in various forms, are heated and electrified to divide into three groups in order to collect them without crushing while maintaining their product forms. Each group consists of high exothermic plastics, low exothermic plastics or PVC.
