Progress in Recycling of Plastic Packaging Wastes

Abstract

The plastic packaging accounts for great proportion in the packaging industry, resulting in great confrontation and challenge for global carbon reduction development because of the plastic packaging wastes (PPW) generation. Thus the fully reasonable utilization of the PPW presents a positive strategy. Based on the international practical policy and demand of PPW management, the article classified the recycling and separation technology, and the reuse and utilization disposal approaches of the PPW. Firstly, it defined the PPW’s source, classification and chemical composition, focusing on the recycling and separation technology principles and practices. Then it discussed several PPW disposal approaches emphasizing on the recycling, and summarized the principles and practices of mechanical recycling, chemical recycling, and energy recycling and biodegradable utilization on the PPW. Finally, it presented a suggestion on recycling and utilization of PPW.
