RECYCLING METHOD OF THERMOPLASTIC RESIN COMPOSITION WASTE MATERIAL, MANUFACTURING METHOD OF PLASTIC COMPOSITION RAW MATERIAL, PLASTIC COMPOSITION RAW MATERIAL, MANUFACTURING METHOD OF PLASTIC MEMBER AND PLASTIC MEMBER

摘要

PPROBLEM TO BE SOLVED: To provide a recycling method of a thermoplastic resin composition waste material in consideration of the global environment capable of reducing the amount to be used of buried fossil resources without lowering physical properties even if the thermoplastic resin composition waste material is regenerated. PSOLUTION: In the recycling method of the thermoplastic resin composition waste material, a thermoplastic resin composition originating from biomass is mixed with the thermoplastic resin composition waste material and the resulting mixture is heated and melted. Further, the thermoplastic resin composition originating from biomass is mixed with a thermoplastic resin composition having compatibility and/or dispersibility with respect to a polystyrenic thermoplastic resin composition.
