Abstract: 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). The process and apparatus can be used with advantage for any type of substrate or printed media, for example for magnetic substrates, photographic substrates, printing plates, pigment-free substrates.

Abstract: PCT No. PCT/EP95/00695 Sec. 371 Date Sep. 9, 1996 Sec. 102(e) Date Sep. 9, 1996 PCT Filed Feb. 25, 1995 PCT Pub. No. WO95/24443 PCT Pub. Date Sep. 14, 1995Magnetic powder and substrate material are separately recovered from finely chopped wastes of magnetic recording media consisting of a polymeric substrate and a magnetic layer present thereon in which finely divided magnetic powder is dispersed in crosslinked or uncrosslinked polymeric binder by treating the finely chopped wastes of magnetic recording media in a solution consisting of the potassium salt of a polyunsaturated fatty acid, or a biodegradable cleaning agent comprising phosphates, surfactants and a complexing agent, and one or more organic solvents or water while being subjected to mechanical action, and separately removing the magnetic powder from the substrate material by washing or sedimentation or in a magnetic separator.
