The invention relates to a process for working up aluminum composite films, in particular Al / PVC composite films. The aim of the invention is to provide an economical process for the processing of composite films without the hitherto required apparatus technical effort. Based on the technical causes of the defects of the known solutions, the invention has for its object to provide a method for processing composite films without supplying thermal energy, which also allows the recovery of all components of the composite film. According to the invention, the object is achieved in that the Al / PVC composite is pre-comminuted in a known manner, then an intensive mechanical stress, for example in Schlaegermuehlen, is subjected to the solution of the composite and the resulting mixture in an aluminum and plastic fraction according to known Method is sorted. |
