biogas
Fermented waste energy
Biogas is a fuel gas produced by the breakdown of organic matter—manure, sewage, food waste, or plant material—in the absence of oxygen.
It consists mainly of methane and carbon dioxide.
Biogas can be burned for heating, electricity generation, or refined into vehicle fuel.
The farm converts pig waste into biogas to power its operations.
