Patent ID: 7699248

Claim:
A method for recycling a waste material of a thermoplastic resin molded article as resources, comprising: a pulverization step of pulverizing a mixture of plural kinds of thermoplastic resin molded articles, each having a different softening point in a resin substrate thereof and having a metal part attached thereto and a coating film coated thereon; a metal-material selection-removal step of selecting and removing a metal material of the pulverized metal part from pulverized pieces obtained through said pulverization step by a selection apparatus; a pulverized resin-material selection step of selecting a target pulverized resin material for recycling by allowing the pulverized pieces from which the pulverized metal material has been removed through said metal-material selection-removal step to drop and by ejecting gas toward either one of the target pulverized resin material for recycling and a non-target pulverized resin material, which are contained in the pulverized pieces dropping, for changing a drop direction thereof; and a coating-film peeling step of peeling the coating film from the resin substrate by applying a shearing force to the target pulverized resin material for recycling that has been selected through said pulverized resin-material selection step under the softening point of the resin substrate of the target pulverized resin material for recycling.
