How it works

From dung to a lit stove

25–50 kg of dung a day, mixed one-to-one with water, goes into the inlet. That is the dung of three to six animals.

Bacteria break the slurry down without oxygen over 30–40 days, at 15–30 °C. No electricity, no moving parts. Methane collects in the floating dome and feeds your stove through a one-inch line at 0–5 psi. 50–80 litres of nutrient-rich slurry leaves the outlet every day — worth Rs 25,000–45,000 a year on its own.Feed it25–50 kg2,000 L · 30–40 days · 15–30 °CIt digestsGas rises1–1.5 m³/day1" · 0–5 psi3–5 hrs/dayFertiliser comes out50–80 L/day

    Feed it

    25–50 kg of dung a day, mixed one-to-one with water, goes into the inlet. That is the dung of three to six animals.

  2. 02

    It digests

    Bacteria break the slurry down without oxygen over 30–40 days, at 15–30 °C. No electricity, no moving parts.

  3. 03

    Gas rises

    Methane collects in the floating dome and feeds your stove through a one-inch line at 0–5 psi.

  4. 04

    Fertiliser comes out

    50–80 litres of nutrient-rich slurry leaves the outlet every day — worth Rs 25,000–45,000 a year on its own.

How we deliver

  1. 01

    Survey & assessment

    We assess energy need, livestock numbers and the biogas a site can realistically produce.

  2. 02

    Community engagement

    We brief village councils and households on how the technology works and what it asks of them daily.

  3. 03

    Installation & training

    Site preparation, installation, and training the household on daily feeding and safe operation.

  4. 04

    Monitoring

    Follow-up visits, performance checks and support after handover.

How much dung does a biogas plant need?

A ZES-500 needs 25–50 kg of dung a day, mixed one-to-one with water. That is the output of three to six cows or buffaloes.

Does a biogas plant need electricity?

No. There are no moving parts and no electrical supply is required.
