Zusammenfassung:	PROBLEM TO BE SOLVED: To continuously process a waste of bulky foamed polyurethane, which is compressed into a high density.SOLUTION: A method includes the steps of: heating the foamed polyurethane; applying a shearing force thereto for pressurization; and reducing the volume by the compression of the foamed polyurethane. Thereby, the density of the foamed polyurethane is increased. Preferably, a screw extruder may be used.
