Ecological, energy, and economic concerns urge China to push the bio-fuel industry forward. The Chinese bio-fuel industry is divided into two sub-segments, the bio-ethanol sector and the bio-diesel sector. In terms of market size, China has the third largest bio-fuel market around the globe, only after the U.S. and Brazil. China was estimated to produce more than 360 kt of bio-diesel and 1,620 kt of bio-ethanol in 2008. During the past eight years, China has primarily established a legal and administrative system for bio-fuel, especially for the bio-ethanol industry.
