Bio-gas is produced naturally through process of anaerobic decomposition from waste and bio-mass sources like agriculture residue, cattle dung, municipal solid waste, sugarcane press mud, sewage treatment plant (STP) waste, etc.
It is called CBG after biogas is purified and compressed, which has pure methane content of over 95%.
CBG is exactly similar to commercially available natural gas in its composition and energy potential.
It has calorific value (~52,000 KJ/kg) and other properties are similar to CNG.
CBG can be used as alternative, renewable automotive fuel.
It has potential to replace CNG in automotive, industrial and commercial uses in the coming years, given the abundance of biomass in the country.
Advantages of converting agricultural residue, cattle dung and municipal solid waste into CBG on commercial scale are
It results in responsible waste management, reduction in carbon emissions and pollution.
It generates additional revenue source for farmers.
It boosts entrepreneurship, rural economy and employment.
It supports national commitments in achieving climate change goals
It also helps in reduction in import of natural gas and crude oil.
It also serves as buffer against crude oil and gas price fluctuations.
