Abstract
A method for treating plastics, which is feasible on plastics containing films mixed therein, which is capable of performing dehydrochlorination simultaneously, and which provides processed plastics capable of being easily size-reduced. The method includes mixing the plastics with an organic solvent at a temperature not lower than 150.degree. C.; allowing the plastics to dissolve and/or swell; removing the organic solvent or both the organic solvent and low-boiling point components from the treated solution thereafter; and solidifying the resulting product. The method can produce solid fuels and reducing agents for ores.
