Biogas Plant
Biogas plants use anaerobic digestion of organic waste to produce methane-rich gas that can be burned for heat or electricity.

From waste to gas
In a biogas plant, organic waste (e.g. animal dung, kitchen waste) is fed into a sealed digester where microorganisms break it down without oxygen, producing biogas (mainly methane and CO₂). The gas can be used for cooking or to run a generator.
✔ Key takeaway: Biogas plants turn organic waste into useful fuel while reducing pollution.
Environmental benefits
Using biogas can reduce reliance on firewood and fossil fuels and cut methane emissions that would otherwise escape from rotting waste. Slurry left behind can be used as fertiliser.
✔ Key takeaway: Biogas is a renewable, low-waste energy source with multiple environmental benefits.
