摘要

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。
