我国聚乳酸产业发展现状与对策研究

China’s Polylactic Acid Industry:Current Status and Development Strategies

聚乳酸作为典型的碳中和、可再生、生物全降解高分子材料,正逐步发展成为国民经济和社会发展所必需的基础性大宗原材料。聚乳酸材料产业链涵盖乳酸单体的生物制造,乳酸单体的化学聚合,聚乳酸改性、加工、成型与产品制造,聚乳酸材料质量体系与环境释放管理等,是集生物发酵工业、化学化工工业、高分子材料工业、现代管理等技术成就于一体的新型产业。本文立足国情实际和产业需求,在比较分析国内外聚乳酸材料技术研究与产业现状的基础上,着重对我国聚乳酸材料产业发展中原料供给多样性与安全平衡、生产工艺技术与装备、产业链产品多样性与重点发展方向、质量控制体系与环境释放管理评价体系、政策引导与扶持等方面存在的问题与对策进行分析研究。相关内容可为聚乳酸的技术攻关、应用拓展、产业发展提供基础性和启发性参考。

Polylactic acid,a typical carbon-neutral,renewable,and biodegradable polymer,has been gradually developing as a kind of fundamental bulk raw material required for national economic and social development.The industrial chain of polylactic acid materials is composed of bio-manufacturing of lactic acid monomer;chemical polymerization of lactic acid monomer;modification,processing,and molding of lactic acid;product manufacturing;quality control and environmental release management of lactic acid materials.It is a new industry section collected with the latest technical achievements in bio-fermentation industry,chemical industry,polymer material industry,and modern management.Based on a comparative analysis of the status quo of technology research and industry development of polylactic acid materials in China and abroad,following aspects focusing on the problems and countermeasures in the development of China’s polylactic acid material industry were discussed and proposed:the diversity and safety balance of raw materials supply,manufacturing technology and equipment,product diversity and key development areas of the industrial chain,quality control system and environmental release management and evaluation system,policy support and guidance.This study can provide references for polylactic acid technique evolution,application expansion,and industrial development.
