Biogas is a type of biofuel having a mixture of gases which is naturally produced by decomposition of organic matter by anaerobic process. It mainly contains methane and carbon dioxide.

The biogas production involves the following three proceses:

$1.$Anaerobic digestion: The species of Clostridium and Pseudomonas anaerobically digest the waste and the complex insoluble polymers are convered into monomers. This step is also called solubilization.

$2.$Acidogenesis: The monomers from previous step is changed to organic acids by acidogenic bacteria

$3.$Methanogenesis: The last step of biogas production. Methane is produced from the organic acids along with carbon dioxide
