Most kitchens here still run on charcoal and firewood — bought daily, burned once.
Meanwhile the same households and farms throw away the one fuel they already own: organic waste. Cattle and pig dung, poultry droppings, food and market waste — fed into a sealed digester, it becomes gas that lights first time, every day.
No smoke. No charcoal run. And what comes out the other end goes straight back to the field.
One sealed loop.
Inside the digester, bacteria break down organic matter without oxygen. The gas rises off to your stove; what's left is a rich, ready-to-use slurry for the garden or field.
Organic waste
Cattle and pig dung, poultry droppings, food and market waste — the inputs you already have on site.
Biogas
The digester captures methane-rich gas and pipes it straight to a clean-burning stove — no smoke, no charcoal.
Bio-slurry
What comes out is a nutrient-rich organic fertiliser — feed it back to crops and pasture to close the loop.
We match the digester to your site, herd size and budget.
Fixed-dome
digesters
Brick-and-mortar domes built into the ground — durable, permanent installations sized for farms and institutions with steady, high-volume feedstock.
Balloon (bag)
digesters
Flexible tubular digesters that install fast at lower cost — a practical entry point for households and smallholders moving off firewood and charcoal.
From first visit to a working stove.
Every job starts with a real look at your site. We size the system to your waste and your needs, build it, and stay on to make sure it keeps running.
FULL SERVICE LIST→Site assessment
We visit, measure your feedstock and space, and tell you honestly what will work.
System design & quote
Following a site assessment visit, a digester sized to your daily waste, with a clear cost and expected gas output, will be designed.
Construction & installation
Our field crews will build and connect the system, from excavation to point of use.
Commissioning
We do a full check of the entire build before handing it over to you:
- —Digester tank for leaks and seals
- —Gas piping, valves and safety devices
- —Slurry inlet and outlet chambers
Once commissioned, your system is ready to use.
Training
We show you how to feed, run and get the most from your system:
- —You get a commissioning warranty certificate and user manual
- —Our team confirms expected gas output vs. your daily waste
Maintenance
We stay reachable for servicing and repairs, so the gas keeps flowing for years.
In the field, across Zambia.

From Zambia to Uganda: BTZ Completes First International Biodigester Project
Biogas Technology Zambia (BTZ) has completed its first international commercial project in Jinja, Uganda. A 200m³ biodigester was installed at Yalelo Uganda between Nov 2025 – Jan 2026 to process 1,000–3,000kg of fish mortalities daily. The plant now produces 100–120m³ of biogas per day, which fully meets cooking and water heating needs for 1,200 workers, and 110–135 tonnes of organic fertilizer.

A village biogas project tests Zambia’s push to improve rural energy access
A biogas project in Zambia’s Nkhundye village is turning cattle dung into energy for cooking, irrigation, and meeting limited electricity needs. The system was serving about 100 households as of March this year, with plans to expand cooking gas access to 600 community households using underground pipes and portable gas bags. Nonprofits and development agencies bore the initial costs of installing
