Your firewood burns orange.Biogas burns blue.

The same three to six animals you already keep will give a household three to five hours of clean cooking gas every day — and organic fertiliser on top. No monthly fuel bill. Designed and manufactured in Pakistan.

The old way

Rs 65–75per cooking hour

LPG, firewood, kerosene. Smoke in the kitchen, money out of the house, forest cut down.

With ZES

Rs 5–12per cooking hour

Gas from dung you already have. Clean flame, no smoke, and fertiliser for the field.

This is the flame

Filmed at a household stove running on a ZES digester. Firewood and LPG burn orange because they burn dirty. Methane burns blue. It is the difference you can see from across the kitchen — and the reason a pot gets hot without coating itself, or the room, in soot.

01 — Average annual household benefit on a ZES-500

Roughly 70% of rural Pakistan still cooks on wood, kerosene or dung.

That dependence costs households money they do not have, costs women hours of every day, and costs the country its forests. ZES converts livestock manure into clean cooking gas and nutrient-rich fertiliser, using a resource rural families already own.

Figures from the ZES cost–benefit analysis prepared for Mobilink Microfinance Bank. Actual savings vary with household size, livestock, ambient temperature and local fuel prices.

How many animals do you have?

Every digester is sized by the dung it gets each day, and that comes from your animals. Move the slider.
