METHOD FOR SEPARATELY COLLECTING WASTE PLASTIC COMPOSITE MATERIALS, COLLECTED PLASTICS, REPRODUCED PLASTICS, AND REPRODUCED PLASTIC PRODUCTS

摘要

PPROBLEM TO BE SOLVED: To provide a method for separately collecting waste plastic composite materials which can separately collect plastics high in impact resistance, collected plastics, reproduced plastics, and reproduced plastic products. PSOLUTION: The method for separately collecting plastics from the waste plastic composite materials containing one or more plastics includes a process in which the waste plastic composite materials are crushed at temperatures higher than the brittle temperatures of the plastics contained in the waste plastic composite materials, and the obtained fragments 1 are classified according to their sizes and a process for selectively recovering large-sized fragments 2.
