There we meet the owner of the farm, who explained us the functioning of the biodigester. They have been using it for 7 months now. They have around 1300 cows for milk production, which produce around 15-20 ton of dung every day.
Components of the system:
- All water used in the farm goes to a lagoon along with the wastes.
- Then in a series of tanks, water is separated from solids.
- Finally the water is fed to the biodigester, designed like a lagoon.
- Gas produced is collected, measured and burnt for carbon credits.
