Sources of green energy are increasingly being discussed, designed, and developed as nations are realizing the pressure of global warming and harmful effects of greenhouse gases. Owing to these reasons, biogas has become an integral part of the energy generation mix in most countries, as they are trying to reduce their dependence on conventional sources of energy. Biogas is produced by using municipal waste, plant material, agricultural waste, manure, green, waste sewage, or food waste. This renewable source of energy has a very low carbon footprint and it offers multiple benefits.
