Molded polyurethane articles are made by reacting polyisocyanates with polyol compositions obtained by chemical decomposition of polyurethane and/or polyurea waste in a mold. The polyol compositions employed in this invention have an OH value of from about 100 to about 500 mg KOH/g a water content of from 0 to about 5 wt.% and a viscosity at 20°C of more than 2 000 mPa~s. These molded polyurethane articles preferably have a sandwich structure in which the core is a polyurethane and there is at least one outer layer made from an optionally fiber-reinforced plastic material. These molded polyurethane articles are useful in the motor vehicle furniture machine and equipment manufacturing industries.
