Report on the Development Status of Chinese Biogas Industry

On the basis of investigation and statistics, data (up to the end of 2009) have been gained on the discharge of industrial wastewater and residue, agricultural livestock excrement, municipal waste and sludge from sewage treatment plant of China, as well as the amount of biogas convertible resources. The report has discussed the current development of the large and medium sized biogas projects of China, its main contents are as follows: (1) The number of biogas projects, scale, annual biogas production, project investment and economic benefit. (2) The major process technologies, equipment and auxiliary devices adopted by all kinds of biogas projects, the standards of the available technical equipment and the specific plans for the national standard of the key technical equipment. (3) Problems in the design, construction, operation and management, project certification,special team construction and their solutions. (4) Centralized mode of biogas projects and environmental protection. (5) Utilization of biogas, fermented residue and liquid. (6) Cases. In addition, the constraints for the industrialized development of the large and medium sized biogas projects of China have been analyzed and corresponding suggestions on the policy and technology have been put forward in the report.

Biogas Handbook

In line with the ever increasing price of energy, biomass energy sources such as biogas have entered a new phase of development. Household biogas technology has enjoyed a period of rapid development, and the technology is continuing to mature, with more varieties and models developing, and the field of use becoming ever wider. In order to assist more peasants to easily choose an appropriate digester, this book has been written as a reference to aid the comprehensive use of biogas and its digesters. This book features a systematic and detailed explanation of the types and application environments of digesters, construction and commissioning of digesters, use and management of biogas, and the comprehensive holistic use of gas. This book is designed for farmers and friends interested in using biogas.

Demonstration Project Biogas Power Generation from Agricultural and Herding Waste

The project belongs to the competitive grants sub-activities of the priority demonstration projects at the provincial level. After the project put into operation, the first phase project will produce daily about 10,000 cubic meters of biogas with the installed capacity of 1MW, daily power generation of 20,000 kWh, annual power generation of 7.5 million kWh, daily production of 8 tons of solid organic fertilizer, and daily production of 200 tons of liquid organic fertilizer. At the same time, the annual methane emission reduction can reach nearly 0.9 million cubic meters equivalent to reducing CO2 emissions of 3,240 tons / year.
