Use of domestic and municipal waste replacing cow dung for biogas production

Brief description:

  • Cow dung is replaced by shredded vegetable waste (C:B ratio is to be calculated)
  • Two time feeding ( with the same amount)/day increases about 60% gas production.
  • FeCl3 (500 ppm) separated the solid from the slurry.
  • Reuse of the separated solid (50%) increases the SRT of the digester and the gas production.


Utility benefit:

  1. Use of domestic municipal and other biological waste material for the generation of bio-gas.
  2. Least or no requirement of cow dung for the same.
