Effluent in.
Energy out.
Compliance built in.

Food processing, dairy, distillery, and pulp facilities generate organic-rich effluent and solid waste streams that ETPs treat as a cost. Anaerobic digestion turns those streams into recoverable energy and ZLD-compatible discharge.

What makes factories different

The waste line becomes a P&L line.

Industrial digesters are big, typically processing 20–200 m³/day of effluent plus solid waste. The economics flip: gas value alone often justifies the plant, with ETP load reduction, ZLD credits, and carbon credits as additional lines.

Gas → boiler offset
Direct furnace-oil / coal displacement
ETP load down 30–60%
COD/BOD pre-reduced before ETP
ZLD progress
Digestate processable for water recovery
Carbon credits
VCS / GS · industrial-scale issuance
How it works · in this sector

From waste to working plant.

Same four-stage process across every sector, but tuned to the inputs, peaks, and outputs that matter here.

P.01
Process effluent + solids
Pre-screened, equalised before digester
P.02
High-rate digester
UASB or hybrid · 2–4 days HRT
P.03
Gas → boiler / CHP
Furnace-oil or coal direct offset
P.04
Treated effluent → ETP
Pre-reduced load to existing ETP
Feedstock

What goes in.

The substrate determines plant size, gas yield, and everything downstream. Here is what we typically design for in this sector.

F.01
Process effluent
20–200 m³/day
High-COD streams from dairy, F&B, distillery, pulp.
F.02
Solid organic waste
2–20 t/day
Off-spec product, sludge, pulp residue, co-digested.
F.03
Wash & rinse water
Continuous
Pre-treatment captured stream, slurry input.

Industrial digesters often pay back in 2–4 years on furnace-oil or coal offset alone.
Estimates are illustrative ranges. Site-specific output depends on feedstock quality, weather, and operating conditions.

Built around the regulations that govern factories.

Compliance is engineered in from the design stage, sensor-driven audit trails, automatic reporting, and pre-filled regulatory submissions are part of the plant, not bolted on afterward.

From decision to dispatch

Five phases. Predictable.

A typical factories deployment moves through these five phases. Timelines are real, not aspirational.

01
01 / Effluent + solids audit
Weeks 1–2
COD/BOD profiling, peak loads, ETP integration plan.
02
02 / DPR + EC filings
Months 1–3
Detailed Project Report, EC if needed, PCB filings.
03
03 / Civil + mech
Months 3–9
Reactor build, gas line, boiler/CHP integration.
04
04 / Commissioning
Months 9–11
Stabilisation, gas quality testing, ETP integration.
05
05 / Carbon credits
Year 2 onward
VCS/GS registration, first issuance year 2.

Frequently asked

Things factories always ask.

Six questions we hear in nearly every first conversation with a factories operator.

Strongly suited: dairy, distillery, brewery, fruit/veg processing, pulp/paper, sugar, starch, F&B contract manufacturing. Marginally suited: pharma, chemical (case-by-case). Not suited: heavy metals, inorganic process streams.
Yes, after H₂S scrubbing and moisture removal, biogas burns cleanly in standard industrial boilers. Most existing boilers need a burner-tip swap, no full replacement.
The digester sits BEFORE the ETP, not in place of it. It pre-reduces COD/BOD by 30–60%, reducing ETP chemical and aeration cost. Your ETP gets easier, not redundant.
A 100 m³/day effluent plant typically issues 8,000–15,000 tCO₂e/year credits, monetisable from year 2 at $5–15/tonne depending on registry and vintage.
Depends on category. Standalone biogas plants attached to existing factories often piggyback on the parent EC. Greenfield major industries need fresh EC. We assess on case basis.
