Biomethane – UPSC Prelims

  • Biomethane is a naturally occurring gas.
  • It is produced by anaerobic digestion of organic matter such as dead animal and plant material, manure, sewage, organic waste, etc.
  • Biomethanation is the process by which organic material is microbiologically converted to biogas, under anaerobic conditions.
  • This gas is produced out of natural degradation process and escapes into the atmosphere unused.
  • If it is trapped and used in automobile engines, it reduces the net impact on environment and at the same time produces useful power.
