Abstract:

This paper conducts a comparative analysis of the current status and developmental trends in bio-based material technologies and industrial ecosystems between domestic and international contexts. It summarizes the enlightenment derived from the advancement of global bio-based material industries, while systematically analyzing existing challenges within China's bio-based material from both policy frameworks and industrial development perspectives. Taking the advancement of carbon peak and carbon neutrality as the fundamental objectives for developing bio-based materials, and considering the diversity in raw material sources, product portfolios, and technological pathways for bio-based materials, six guiding principles for prioritizing bio-based material products development and selecting technological routes in China are established. The study specifically proposes bio-based polyethylene as a strategic focal point for China's bio-based material industry advancement, accompanied by three key recommendations: ①Expedite breakthroughs in core technologies to establish a mature and advanced technological chain; ②Cultivate a stable and reliable raw material supply chain; ③Implement concrete and well-defined policy measures with urgency.

Key words: bio-based materials, non-grain biomass, development trend, policy recommendations, bio-based polyethylene

摘要：

对比了国内外生物基材料技术与产业发展现状及趋势，总结了国外生物基材料产业发展的启示，从政策和产业发展两个层面剖析了国内生物基材料发展存在的问题。从发展生物基材料的根本目的是推进碳达峰和碳中和出发，针对生物基材料原料、产品和技术路线的多样性，提出了我国优先发展的生物基材料产品和技术路线选择要遵循的六个原则，建议将生物基聚乙烯作为我国生物基材料发展的重要方向，并提出了三个方面的建议：一是尽快突破关键技术，构建成熟先进的技术链；二是努力打造稳定可靠的原料供应链；三是尽快完善具体明晰的政策措施。
