Abstract Scope |
Aluminium multilayer packaging systems have the recent years become increasingly popular due to its performance for food preservation. These material systems often consist of two or more layers of organic material (PP, PE, PET etc.) and a layer of aluminium. Up until recently there has not existed any environmental friendly technique for separation of these materials so that the aluminium can be recycled with satisfactory metal yield.
This paper present laboratory scale experiments where steam (i.e. water vapour) at elevated temperature and pressure has been shown to liberate the organic layers from the aluminium. The results show different type of organic material behave differently and that the aluminium does not oxidize significantly at least up to 3 h of treatment at 174 °C and 8 bar pressure. |
