<p>A method for processing material comprising combinations of aluminium and plastic, such as aluminium bottle caps having a plastic coating, comprising the steps of: pyrolysing the plastic in an inert atmosphere, cracking or gasyfying the gases or vapours which are released in the course of pyrolysis, afterburning the coke which remains behind on the aluminium in the course or pyrolysis. The gases or vapours released are recirculated and are used, during pyrolysis, as an inert, oxygen-free medium.</p> |
