a method for recycling comprises a pulverization step of pulverizing thermoplastic resin molded articles , each having a different softening point in a resin substrate and having a metal part and a coupling film , a metal - material selection - removal step of selecting and removing a metal material from pulverized pieces , 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 to drop and by ejecting gas towards either one of the target pulverized resin material and a non - target pulverized resin material 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 under the softening point of the resin substrate of the target pulverized resin material for recycling .
