Key Points

Biogas:

  • It is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically).
  • It primarily consists of Methane and Carbon dioxide. So, option 3 is correct.
  • It can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, or food waste.
  • It is a renewable energy source.
  • In India, it is also known as "Gobar Gas".
  • The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen.
  • This energy release allows biogas to be used as a fuel.
  • It can be used for any heating purposes, such as cooking.
  • It can also be used in a gas engine to convert the energy in the gas into electricity and heat.
