- Animal dung, dry leaves, wet garbage get decomposed by anaerobic microbes in a biogas plant.
- This produces methane gas, also called biogas.
- Biogas is a very cheap fuel option which meets the demand for cooking gas. It is also used for the production of electricity.
- Biogas contains about 55% to 60% methane and the rest is carbon dioxide.
- Biogas is a fuel which is convenient to use and, in addition to this, a very good manure is also produced as a side product of the process.
- Biogas production process – Production of biogas is an anaerobic process. It takes place in two stages.
(a) Production of acids – The microbes act on the biodegradable complex organic compound and produce organic acids.
(b) Methane gas production – The methanogenic bacteria act on the organic acids to produce methane gas.
