Bio-based chemicals technology innovation and prospects facing resource and environment challenges

Bio-based chemicals are synthesized from sustainable and renewable biomass by biological catalysts. The superiorities of the new industrial mode are obvious, such as independence of fossil resources, and avoidance of energy consumption and pollution. Taking account of the sustainable development of resource and environment, green synthesis will dominate in future bio-based chemicals manufacturing, i.e. using renewable biomass to substitute fossil resources. In this article, development of bio-based chemicals was reviewed from the aspects of research and industrialization. In the future, bio-based chemicals technology will be diversified in terms of feedstocks, efficient transformation systems and high-valuable products. The key scientific problems related to high-effective bio-transformation process was discussed, together with the future development direction of bio-based materials production, which combined biological technology with other technologies (e.g. biology, chemical or process control).
