资源与环境是人类在21世纪实现可持续发展所面临的重大问题,生物技术和生物质资源将成为解决这一问题的关键之一。生物基高分子材料是传统化学聚合技术和工业生物技术的完美结合。目前世界上合成的高分子材料主要是石油化工材料,与之相比,生物基高分子材料具有原料可再生等特点,开发前景广阔。据统计,2011年全球生物基原料生产的可降解和非降解的高分子聚合物达到116.1万t,预计2016年可达578万t,从2011年后的5年内,主要的增长将源自生物
Resources and environment are the major problems facing mankind in achieving sustainable development in the 21st century. Biotechnology and biomass resources will be one of the keys to solving this problem. Bio-based polymer materials are the perfect combination of traditional chemical polymerization technology and industrial biotechnology. At present, the synthetic polymer materials in the world are mainly petrochemical materials. Compared with bio-based polymer materials, they have the characteristics of renewable raw materials and the like, and have broad prospects for development. According to statistics, in 2011, biodegradable and non-degradable macromolecular polymers produced from bio-based raw materials in the world reached 1.161 million tons in 2016 and are expected to reach 5.78 million tons in 2016. From 5 years after 2011, the major growth will come from biological
