Without certification, the right column is waste. With it, it's a second product line.

The second
revenue line.

FOM (fermented organic manure) and LFOM (liquid FOM) is the by-product economy of biogas. Most plants throw it away. BioSarthi's playbook turns it into a second revenue line, GOBARdhan-aligned, with offtake pre-arranged.

The signature surface

Six work-streams. One by-product P&L.

Every BioSarthi FOM/LFOM playbook addresses six work-streams in parallel. The output is a by-product P&L that stands on its own, not a footnote in the gas business case.

FOM is officially a fertiliser under FCO. LFOM is gaining acceptance. We work with both.

How it works

Slurry to revenue, in four stages.

Most plants treat digestate as a problem to dispose of. The FOM/LFOM playbook reframes it as a by-product to monetise. The four stages exist to do this without creating new operational complexity.

P.01
Quality test
Lab analysis, FCO eligibility, brand positioning. 4 weeks.
P.02
Channel selection
Co-ops, FPOs, blenders, retail, captive. Margin compared.
P.03
Contract & launch
Offtake signed, bagging line installed, first dispatch.

Monthly P&L, channel mix tuned, GOBARdhan claims filed.
What's covered

A complete by-product P&L, one tile each.

Each tile is a number on the by-product P&L. Plants treat digestate as a problem to dispose of. We treat it as a product to sell.

GOBARdhan-ready, by default.

FOM and LFOM is a regulated by-product. The playbook is built around FCO compliance, GOBARdhan alignment, and offtake structures that stand up to lender and auditor review.

FCO-compliant by default
Quality testing fortnightly. NPK, OC, moisture documented. Audit-ready.
GOBARdhan claims handled
Market-development assistance, capex subsidy access. We file, you receive.
Offtake contracts pre-arranged
Co-ops, FPOs, blenders. We bring the network; you pick the channels.
Bagging line specified
Right-sized for output. Designed for short payback against the new digestate revenue line.
Brand options
White-label or BioSarthi-network co-brand. Your call.
Monthly P&L
By-product profit reported separately. Visible to lenders and auditors.

In their words

Voices from by-product plants.

"We were paying ₹400/MT to dispose of slurry. Now we're realising ₹4,200/MT bagged. Same molecule, different packaging."
Plant operator
Punjab, since 2024
"The GOBARdhan market-development claim covered the bagging line capex inside year one. The channel margin is pure upside."
Project sponsor
MP, since 2023
"FOM is now 11% of our top line. We hadn't priced it into the original DPR. Free money is overstating it; free-ish is fair."
MSA BioEnergy
Operator partner, since 2024
Frequently asked

Things owners ask first.

No. FOM is fermented organic manure, the digestate from anaerobic digestion. It's a regulated fertiliser under FCO with specified NPK and OC bands. Compost is aerobic and unregulated.
Liquid FOM. The liquid fraction of digestate, increasingly accepted as a fertigation product. We work with both.
Yes. A bagging line at minimum. For LFOM, a tanker-loading facility. Capex is right-sized to output and we design for short payback against the new digestate revenue line.
No. Digestate is already produced. The playbook adds downstream handling, not upstream changes. Operations continue uninterrupted.
Depends on geography. In Punjab and Haryana, FPO channels tend to dominate. In MP and UP, co-ops. Direct-retail works near peri-urban demand.
Yes, the playbook stands alone. But quality data flows more cleanly when telemetry from monitoring is available.
