Studies on packaging waste minimization and its collection system

Case studies in Shanghai showed marked over-packaging of products in market, notable rising trend of plastic packaging waste in domestic waste, bad market management in current waste collection system, and no embodiment of source-producer's responsibility for retrieving the waste. The control methods of manufacturers' responsibility system and the mechanism of the waste retrieval compensation and economic stimulation should be well performed; and the regional packaging waste recycling network system should be set up for higher level of scale-management. Thus, it is possible to ensure the unimpeded packaging waste minimization and the material cycle of its reutilization.
