Description of technology

Biogas is a combustible gas mixture which mainly includes methane and carbon dioxide. It was usually used for heating, cooking, lighting, generating electricity as rural energy. It was produced from organic matter by a variety of microorganism under anaerobic environment. The eligible building of anaerobic digester, sufficient raw material and inoculum are required to produce biogas. Regular feeding and discharging are guaranties for continuous supply of biogas.

Specific Features
Biogas is a clean renewable energy. It can replace firewood, oil, gas, electricity.
