PROBLEM TO BE SOLVED: To convert a plastic material into an oil in high efficiency by the catalytic decomposition of the plastic material in the presence of an activated clay. SOLUTION: An oily substance is produced by the catalytic decomposition of a plastic material such as polyethylene, polypropylene, polystyrene or ethylene-vinyl acetate copolymer resin, a wax, a rubber, an elastomer, etc., in the presence of an activated clay of grade K500 produced by Nihon Kassei- Hakudo Co.
