India has to develop energy based on gas, coal, bio-mass, biogas , water and non-conventional sources, depending on the availability and feasibility.
The hydrogen sulfide in biogas is also hazardous.
Some cleaning is also required but digesters exist that produce sufficiently clean biogas for conventional engine cogenerators, as well as a high grade compost for agricultural purposes.

Using our technology in exploiting biogas will improve production by 60 per cent from the same quantity of material.
But India's government may not have a choice but to keep pushing for the wider use of biogas and other alternative fuels.
