Abstract
The biogas digestion has experienced rapid development for its unique characteristics for dealing with energy shortage and environmental pollution. In this chapter, we reviewed the development trend of biogas projects in China from 2000 to 2014. The significance of developing biogas in China was analyzed by accounting the energy supply and emission reduction. The details about the biogas industrialization were then probed into, with the conclusion that the smallholder farms are gradually transforming to larger-scale farms. The strategic development mode of biogas production industry was summarized. Then, the relationship among three types of biogas industries including biogas plant industry, biogas equipment industry, and biogas service industry was analyzed in detail. Finally, the development planning and development motion for biogas production as well as corresponding policies in China were reviewed. The policies, including energy policies, environmental policies, and economic policies, laws, rules and regulations, and standards for the household biogas projects were summarized, which may contribute to the rapid promotion of biogas project.
