Abstract

Provided is a method for producing a recycled resin, which is excellent in terms of efficiency in recycling molding waste products.A method for producing a recycled resin,the method comprising:a step of irradiating a laser light to a molding waste product consisting of a thermoplastic resin, identifying the type of the thermoplastic resin of the molding waste product based on a Raman scattering light scattered from the molding waste product, and separating and recovering the molding waste product; anda step of obtaining a recycled resin from the separated and recovered molding waste product, whereinthe thermoplastic resin comprises at least one selected from a constituent unit (A) derived from a monomer represented by the following general formula (1), a constituent unit (B) derived from a monomer represented by the following general formula (2), a constituent unit (C) derived from a monomer represented by the following general formula (3), a constituent unit (D) derived from a monomer represented by the following general formula (4), and a constituent unit (E) derived from a monomer represented by the following general formula (5):
