Abstract: Biogas is a green, clean and renewable energy source that has been included in the national energy development strategy. The development of biogas can not only help to alleviate the supply-demand imbalance of natural gas in China, reduce external dependence, ensure national energy security, promote the transformation of energy structure, but also can solve the environmental pollution problems caused by organic wastes such as livestock manure and straw. This article introduces the development status of biogas in China, analyzes the potential for biogas development, and proposes corresponding measures to accelerate the healthy development of biogas. China needs to establish a unified biogas standard, introduce and absorb the foreign mature and advanced technology, conduct independent innovation research to form suitable biogas purification technology and complete sets of purification equipment in China, and increase support in terms of policies and subsidies, especially in subsidies for operation management and end products (biogas, straw, organic fertilizer and liquid fertilizer).

Key words: livestock and poultry manure, straw, biogas
