Abstract:

The global plastic pollution crisis has intensified focus on sustainable alternatives, with non⁃grain bio⁃based degradable plastics emerging as a critical solution that aligns with green development goals while safeguarding food security. While Europe and North America have progressed from technical demonstration to commercial⁃scale production, China has developed a distinctive industrial landscape led by polylactic acid (PLA) and polyamide materials, with multiple bio⁃based technologies advancing rapidly. However, significant challenges persist in four key areas: (1) comprehensive utilization of non⁃grain biomass feedstocks, (2) core industrialization technologies, (3) large⁃scale production cost reduction, and (4) policy standard implementation. To accelerate China's industry development, we proposed a four⁃pronged strategy: (i) breakthrough innovation in core technologies with enhanced commercialization pathways, (ii) optimized industrial planning for rapid capacity expansion, (iii) accelerated standards development to facilitate market adoption, and (iv) whole⁃industry⁃chain cultivation coupled with improved management and recycling systems. These recommendations aim to elevate China's bio⁃based degradable plastics industry to global leadership while addressing critical sustainability challenges.
