We throw away a lot of organic waste — food scraps, garden cuttings, animal manure. Most of it rots in landfill and gives off harmful gas. Waste-to-energy captures that value instead. It turns waste into fuel and cuts what goes to the dump.
What is biogas?
Biogas is made when organic waste breaks down without air, inside a sealed tank called a digester. The process gives off gas you can burn for cooking or heating. What is left over is a rich fertiliser for gardens.
How a community system works
- Collect organic waste. Food scraps, manure and green waste from homes or a market.
- Feed the digester. The sealed tank holds the waste while bacteria break it down.
- Capture the gas. Piped to kitchens for cooking, or to a generator for power.
- Use the leftovers. The residue is a safe, natural fertiliser.
A community biogas unit can cut cooking-fuel costs and reduce landfill waste at the same time — two wins from one system.
Why it matters here
For communities far from reliable power or gas, biogas offers a local, low-cost fuel. It keeps money and resources in the community. And it turns a waste problem into a resource.
Getting started
We assess the waste available, the number of users and the space, then design a system to match. Small household digesters and larger community units are both possible.
Kondebe builds biogas and resource-recovery systems for communities. Explore our Waste 2 Energy services or talk to us about a pilot.
