<p>In order to be able to dispose of devices containing foamed materials in an environmentally friendly manner, such devices are put into a chamber (1) and the foamed material is there shot-blasted so that the plastic foam can be detached under this stream of fluid and the cell structure can be maintained while the blowing agent contained therein can be released. To improved this method of disposal and especially to use less power therein, the shot-blasting process takes place using a cooled stream of fluid, preferably water, the temperature of which is below the boiling point of the blowing agent. The blowing agents thus immediately become or remain liquid.</p>
