LCA Applied to Milk Package Made from Al-PE-Paper Complex and Polythene Xie Minghui Research Institute of Solid Waste Management Chinese Research Academy of Environmental Sciences huibird82@163.com CONTENT 1. PREFACE 2. METHOD 3. CONCLUSION PREFACE The one off consumable with the short life cycle and much waste. The imperfect packaging waste recovery system The laggard research on technology of packaging waste treatment From a holistic perspective, a packaging system not only needs to functional, economic and social requirements but also have a minimum impact on the environment. Environmental requirements, therefore, need to be incorporated into the development of the packaging process, which means that existing packaging methods and materials must be rationalized. PREFACE CONTENT 2. METHOD 1. PREFACE 3. CONCLUSION The environmental performance of package rationality can be evaluated by life cycle assessment (LCA). This approach covers the whole life cycle of the packaging, i.e. the extraction and transportation of raw materials, manufacture of the packaging, collection after use and ?nal disposal. METHOD 1.
