A continuous process for reusing scrap polyurethane involves the following stages: Chips of thermoset polyurethane foam are supported as a bed; the bed of chips while moving is heated; the bed of chips while moving is subjected to pressure or compression; and a web is formed. The resulting material is useful in many industrial applications, including padding, gaskets, and insulation.
