PROBLEM TO BE SOLVED: To provide a method for regenerating a regenerated molded product having characteristics suitable as a target resin molded product, in recycling a waste polyurethane foam material. SOLUTION: The waste polyurethane foam material is fractionated by density and ground to form chips and the fractionated chips of the waste material are selected inclusive of the compounding chips different in density according to circumstances so as to obtain the regenerated molded product with a predetermined density. After the chips are coated with a binder, the coated chips are charged in a mold and molded to manufacture the regenerated polyurethane foam molded product having a predetermined density.
