Abstract:The amount of waste aluminum-plastic composite packaging, which contains a large number of high quality fibers and aluminum-plastic materials increases year by year. In the present paper, separation technologies of aluminum-plastic composites in the world were reviewed. The principle and processes of various separation approaches, such as separation with solvent, electrical separation and Argon electrolysis were analyzed and compared. Finally the existing problem of efficient separation and recycling as well as future research directions of aluminum-plastic composite were discussed.
