废弃塑料污染防治是国家战略的重要组成部分。本文全面深入分析我国废弃塑料的来源、回收利用及回收利用技术的现状。在塑料全生命周期评价基础上，提出了我国塑料污染防治全链条解决方案：在技术层面，必须从塑料合成、加工、应用和处理等各环节全方位全链条防治废弃塑料污染，包括塑料制品源头减量，塑料原料及替代产品的开发，塑料制品循环利用的设计，高性能长服役期塑料制品的加工，废弃塑料清洁高效规模化回收利用，终极塑料垃圾的安全处理等；在政府层面，建议加强政府政策引导，落实行政监管；在企业层面，建立有效回收机制，明确生产者、经营者、消费者的回收责任，为废弃塑料污染防治提供政策及技术建议；在公众层面，提高公民环保意识，全民参与治理。采用上述提出的我国塑料污染防治全链条解决方案，可以促进我国塑料工业和国民经济绿色可持续发展。

Prevention and control of waste plastics is an important component of the national strategy in China. In this study, the sources as well as the current situation and measures for recycling of waste plastics in China were comprehensively analyzed. We proposed an all-rounded tactic for the prevention and control of plastic pollution in China based on the life-cycle assessment of plastics. Technically, waste plastic pollution should be prevented and controlled throughout the entire process covering plastic synthesis, processing, utilization, and recycling; specifically, it includes reduction of waste plastics from the origin by developing new degradable raw materials and their environmentally friendly alternatives, design and processing of high-performance plastic products with extended service life, development of new technologies offering efficient and large-scale capacity for recycling waste plastics, as well as safe disposal of the ultimate plastic wastes. At the government level, policy guidance must be strengthened, and administrative supervision be implemented. At the enterprise level, an effective recycling system should be instituted to clarify recycling responsibilities of producers, sellers, and consumers, providing policy and technical suggestions for the prevention and control of waste plastics. At the public level, citizens’ environmental awareness must be aroused to promote a nationwide participation in waste management. These suggestions are favorable to a more green and sustainable development of China’s plastic industry and even national economy.
