Biogas is a flammable mixture of 50-80% methane, 15-45% CO2, 5% water and some other trace gases.Biogas is produced by biomethenation and is self regulating symbiotic microbial process operating under anaerobic conditions and functions at temperature around 30oC.

2. What is Biogas???
• When methane is produced by the
fermentation of animal dung the gaseous
products are usually referred as biogas and
the installations are called biogas plant or
bioreactor.
• Biogas is a flammable mixture of 50-80%
methane, 15-45% CO2, 5% water and some
other trace gases.

• Biogas is produced by biomethenation and is
self regulating symbiotic microbial process
operating under anaerobic conditions and

6. Anaerobic Digestion
Anaerobic Digestion is accomplished in three stages
• Solubilization
• Acidogenesis
• Methanogenesis.

8. Advantages of Biogas
• Anaerobic digestion of municipal industrial and
agricultural wastes can have positive
environmental values, since it can combine waste
removal, stabilization and net yield of biogas
formation.
• Solid or liquid residues can be used as fertilizer,
soil conditioner or animal feed. hence biomass
production continues to have high priority in
alternative energy research
