Abstract: Spent polyurethanes are returned to the value chain by hydrogenating the spent polyurethanes in a hydrogen atmosphere in the presence of at least one homogeneous transition metal catalyst complex, wherein the transition metal is selected from metals of groups 7, 8, 9 and 10 of the periodic table of elements according to IUPAC, to obtain a polyamine and a polyol. The hydrogenation is carried out at a reaction temperature of at least 120° C. in a non-reducible solvent having a dipole moment of 10-1030 C·m or less.
