摘要：
PROBLEM TO BE SOLVED: To provide a method capable of lowering expense for recycle treatment and recovering useful materials from a waste plastic.
SOLUTION: In the method for recovering the useful materials from the waste plastic, at least one substance selected from a group consisting of a tertiary amine represented by the general formula (R1, R2 and R3 are each a hydrocarbon group), a carbonate of an alkali metal a carbonate and an oxide of an alkaline earth metal are added as a catalyst to a solution in which the waste plastic and monohydric alcohols or monohydric phenols exist and a polycarbonate resin in the waste plastic is chemically decomposed to recover the decomposed product.
