专家报告：我国生物基材料发展现状及高质量发展路径（附37页PPT）

Core Viewpoint - The article discusses the rapid development and increasing production capacity of bio-based materials globally, driven by the need to address climate change and reduce plastic pollution. Major chemical companies are investing in this sector, with significant growth expected in bio-based plastics and chemicals over the next few years [9][10]. Global Bio-based Plastics Production Capacity - Global bio-based plastics production capacity is projected to increase from 2.22 million tons in 2022 to 6.3 million tons by 2027, with an annual growth rate of 23% [9]. - The current domestic production capacity of bio-based materials in China is approximately 11 million tons, with an output of around 7 million tons and a market value exceeding 150 billion yuan [9]. Development Trends in Bio-based Materials - Countries like the US, EU, Japan, and China have implemented policies to promote the development of bio-based materials and bio-economy [10]. - The industry is focusing on expanding the variety of bio-based materials, shifting from food-based to non-food biomass as raw materials, and enhancing recycling efficiency [13]. Key Areas of Bio-based Chemicals - Bio-based chemicals include organic acids, amino acids, and platform chemicals, with a wide range of applications in food, pharmaceuticals, and agriculture [12][25]. - China is the largest producer and exporter of amino acids, with significant export ratios for glutamic acid, lysine, and threonine [25]. Bio-based Fuels - Biofuels, including biodiesel and biojet fuel, are produced from various biomass sources, with biodiesel production capacity in China reaching 454,000 tons in 2023 [64][70]. - The article highlights the challenges in the biofuel sector, such as high production costs and raw material supply instability [69]. Bio-based Resins and Polymers - Bio-based resins like polylactic acid (PLA) and bio-based nylon (PA) are gaining traction, with PLA production capacity around 850,000 tons per year, primarily in China, the US, and Thailand [49][54]. - The bio-based nylon industry is rapidly developing, with significant investments and expected demand growth of around 30% over the next five years [53]. Future Outlook - The OECD predicts that over 20% of petrochemical products could be replaced by bio-based products in the next decade, with the EU forecasting that 6-12% of chemical feedstocks and 30-60% of fine chemicals will be bio-based by 2030 [13].
