Method for recovering raw materials from polyurethane products, comprising the steps of: (A) providing a polyurethane product based on an isocyanate component and a polyol component; (B) reacting the polyurethane product with an alcohol in the presence of a catalyst, to give a first product mixture containing alcohol, polyols and carbamates, and optionally water; (C) working up the first product mixture, comprising: (C.I) mixing the first product mixture obtained in step (B) with an organic solvent, wherein the alcohol used in step (B) and the organic solvent used in step (C.I) are chosen such that the two are miscible under the conditions of step (C.I), i.e. at the temperature and the ratio of organic solvent to alcohol, optionally followed by a removal of solid constituents, to obtain a second product mixture; (C.II) washing the second product mixture obtained in step (C.I) with an aqueous wash liquid, with partial hydrolysis of carbamates present in the second product mixture to release amines and alcohol, and phase separation into a first solvent phase containing organic solvent used in step (C.I) and polyols, and a first aqueous phase containing water, alcohol, carbamates and amines; (C.III) working up the first solvent phase to obtain the polyols; and optionally (D) working up the first aqueous phase to obtain an amine corresponding to an isocyanate from the isocyanate component.
