Abstract
There is disclosed a method of treating a fire-retardant resin material, or a thermosetting resin material whose base is an epoxy resin or an ABS resin, to yield oil substances, which method comprises causing hydrocracking of a resin material in a hydrogen-donating solvent in the presence of a porous carbonaceous substance in a nitrogen atmosphere at 300 to 420.degree. C., to yield an oil substance. According to the treatment method to yield oil substances, fire-retardant resin materials and thermosetting resin materials whose decomposition has hitherto been difficult, can be converted entirely to oil substances, which can be reused as fuels or the like, and the volume of the resin materials can be reduced considerably. Therefore, the method can greatly contribute to the waste disposal and recycling.
