<p>A mixture of a methylene chloride solution as a halogen-containing solvent or a chlorine-containing solvent with water is put in a treament tank to generate vapors. The generated methylene chloride vapor, water vapor, and occasionally surfactant vapor penetrate into a waste synthetic resin film (W). When the interior of the treatment tank (T) is evacuated, chloride ions (Cl-) and methylene free radicals (-CH2-) generated from the vapors exhibit an oxidative effect for a longer time more strongly than usual. This breaks a long-chain hydrocarbon molecule constituting the synthetic resin or the like to carbohydrates, alcohols, and water, so that the waste is dissolved or decomposed. Further, harmful components of PCB and fat or oil components of animals, fish and the like are decomposed.</p> |
