Feedstock in. Gas to GAIL. Fertiliser back to the farm.
One digester, two products, one catchment. Follow the tonnes and the rupees through a 10 TPD plant as it is designed to run. Figures are design values from the evaluated DPR; operating figures publish after commissioning.
What happens to a tonne of residue.
Press mud from sugar mills, cattle dung, crop residue and organic market waste — about 250 tonnes a day at design, in ratios that change with the season. Contracted before the digester is sized.
Every load crosses the weighbridge; the farmer or mill is paid on weight, to a bank account. The weighbridge record is also the audit trail for the impact figures.
Continuously stirred tank reactors — 17,017 m³ in total, nine agitators — hold the mix for 20 to 35 days while microbes turn it into raw biogas and a nutrient-rich digestate.
Water scrubbing lifts methane to 96% (±1) with two-stage hydrogen-sulphide removal, meeting IS 16087:2025 — the Indian Standard every batch is tested against before dispatch.
Compressed to BioCNG — 10 tonnes a day at design — metered at the gate and sold to GAIL for the CGD and CNG network at the administered price under GOBARdhan.
Separated into solid and liquid organic fertiliser, tested for nutrients and contaminants, and dispatched — the second product, treated with the same seriousness as the gas.
Fertiliser returns to the fields the residue came from, at a fair rate. The farmer is supplier and customer; value stays in the catchment. That retained share is the metric we publish.
Three cash flows, one loop.
BioCNG sold at the administered price — ₹2,110 per MMBTU under GOBARdhan, with a minimum ten-year horizon. This is the flow that makes the plant bankable.
Residue bought by weight, paid to bank accounts. Priced so that supply keeps arriving — the plant's raw material is a farmer's decision every season.
Solid and liquid organic fertiliser sold back to the catchment and beyond, competing on cost-per-outcome. Digestate is a product line here, not a disposal cost.
of gross feedstock value taken from the catchment returns to it — through residue payments, fertiliser and local employment. Published with first-cycle reporting and marked as a target until then.
Value returned to the sourcing catchment as a share of gross feedstock value taken out of it.
The loop is the investment case.
Three models run this same loop at different scales and risk profiles.
