Abstract: The present invention relates to a device for processing plastic waste, such as packaging foil of polyvinylchloride, polyethylene, polypropylene etc. into blocks by compressing it in a container. The processing of the plastic waste is achieved by compressing with a punch at a temperature of 120.degree.-180.degree. C. and a pressure of 250-400 g/cm.sup.2 and preferably at a temperature of 140.degree.-160.degree. C. and a pressure of 260-290 g/cm.sup.2, followed by cooling with air. The cooling is carried out by the introduction of air in the container by a fan, which cooling takes place in 5-15 minutes, and preferably 8-10 minutes. The device of the invention is provided with a punch, whereas the inner surfaces of said container and/or the punch are provided with a coating in order to prevent said softened and compressed plastic waste from adhering to the walls. The coating is preferably teflon, whereas the heating elements advantageously are electrical heating elements.
