Title:
METHOD FOR RECYCLING THERMOPLASTIC RESIN, AND METHOD FOR PRODUCING MOLDED THERMOPLASTIC RESIN ARTICLE AND MOLDED THERMOPLASTIC RESIN ARTICLE
Document Type and Number:
Japanese Patent JP2008019306
Kind Code:
A
Abstract:

To provide a method for efficiently recycling a thermoplastic originated from fossil resources, by which high quality thermoplastic resin molded articles having characteristics suiting various uses can be obtained under consideration of environmental loads.

This method for recycling a fossil resource-originated thermoplastic resin contained in waste plastics is characterized by comprising a selection process for selecting the fossil resource-originated thermoplastic resin from the waste plastics, and a molded article-producing process for mixing, heating and melting the fossil resource-originated thermoplastic resin with a biomass-originated thermoplastic resin and then molding the melted mixture to obtain the molded thermoplastic article. The mixing ratio of the fossil resource-originated thermoplastic resin with the biomass-originated thermoplastic resin is determined according to the requirement characteristics of the obtained molded thermoplastic article. A method for producing a molded thermoplastic article by the method, and a molded thermoplastic article.
