Patent number: 6223904Abstract: Continuous recovery of raw materials from coated films and apparatus for this purpose and film material recovered therewith. Large amounts of coated films can be fed to a continuous recycling process in which any pigments present in the coating and the substrate material are recovered. The treatment is carried out at room temperature in an alkaline medium consisting of soft soap, organic solvent and/or water, with or without the use of a catalyst. The solvent is recycled. After the first treatment stage, the film shreds can be treated in a second stage with a solvent/water mixture similarly to the first stage, and thorough final washing in a water or solvent circulation is effected in a third stage. The recovered film shreds are dried, pressed, milled and brought to the desired shape in a plastics agglomerator, and the recovered pigments are dried under reduced pressure (FIG. 1).Type: GrantFiled: October 8, 1998Date of Patent: May 1, 2001Assignee: EMTEC Magnetics GmbHInventors: Oskar Stephan, Franz Weingart, Uwe Burkhardt, Heino Thiele, Lothar Schwarz, Norbert Müller, Jochen Eicher
