1. Development
A. The peak of biogas development of new China initiated in 1958.
• Lack of scientific programming and practical
technical regulation, over 100,000 digesters
were discarded.
• Comprehensive utilization of biogas as three in
one idea “biogas, fertilizer, sanitation ” was
put forward to develop biogas technology in
rural area.

1. Development
B. From the late 1970’s to the early 1980’s, central government stressed
that “to develop biogas technology is an effective way to utilize
natural resources rationally.”
• Established a specific management agency—
— National Biogas Construction Leading
Group
• Established specific research institutions——
Biogas Institute of Ministry of Agriculture
(BIOMA)
• Organized the edition of Chinese rural biogas
digester drawings; Collection of Chinese
hydraulic biogas digester standard drawings

1. Development
C. In 1983，according to “the Sixth Five-Year Plan”, rural energy
development should follow local conditions as a complement to
conventional energy practically and effectively.

D. After 2000, the Chinese government took the development of rural
biogas as the two grand objective of solving the problem of rural
energy shortage and controlling the pollution of environment, biogas
development stepped into a faster development period.
