Described is a method of reprocessing flat substrates, such as foil, sheet or strip, coated with metal, in particular aluminium. The metal is separated from the substrate and granulated. To this end, the invention calls for the metal-coated substrate to be mechanically shredded and the shredded material subsequently ground mechanically in such a way that the metal is detached from the substrate giving granular metal material and fibrous felty substrate material. A pigment is then produced from the granular metal (in the preferred embodiment aluminium). When mixed with a commercially available binder, the aluminium pigment gives a bright, metallic, silvery surface. |
