Abstract

Provided is a method for producing a recycled resin from a waste resin composition, wherein the waste resin composition comprises: a thermoplastic resin B which contains one or more thermoplastic resins that are selected from the group consisting of a thermoplastic resin B1 that contains a structural unit (b-1) which is derived from a monomer represented by general formula (1-1), a thermoplastic resin B2 that contains a structural unit (b-2) which is derived from a monomer represented by general formula (1-2), and a thermoplastic resin B3 that contains a structural unit (b-3) which is derived from a monomer represented by general formula (1-3); and at least one of a thermoplastic resin C which contains only a structural unit (c) that is derived from a monomer represented by general formula (2), and a thermoplastic resin D which contains at least one structural unit that is selected from the group consisting of general formulae (7) to (10). This method comprises: pulverizing the waste resin composition so as to obtain a pulverized material; and sorting out the thermoplastic resin B, and the thermoplastic resin C and the thermoplastic resin D by means of UV.
