Manufacturing process

  1. Procure food waste, municipal waste, and cow dung from various suppliers and store them appropriately.
  2. Crush solid food waste into suitable sizes using the crusher machine.
  3. Mix crushed waste and cow dung with water in the slurry tank equipped with an agitator to form a uniform slurry.
  4. Pump the prepared slurry into the anaerobic digester of the biogas plant where microbes digest the organic matter without oxygen to produce biogas.
  5. Extract the generated biogas from the floating cover dome via flow control valves into compressors and storage receivers.
  6. Pump out the spent slurry/sludge into a sludge tank to be sold or used as organic fertilizer.
  7. Fill the purified/compressed biogas into cylinders or supply it through pipelines to customers.

Market

Biogas serves as an eco-friendly renewable fuel alternative to firewood, LPG, diesel, and electricity. It aids in decentralized waste management and provides both gaseous fuel and organic fertilizer, yielding steady demand across rural and semi-urban markets.
