What is biogas?

Biogas is a renewable energy source produced during the anaerobic digestion process of organic material. During decomposition, organic matter is broken down by microorganisms in the absence of oxygen. Biogas digesters take advantage of these biological processes. They recycle biodegradable materials such as manure, crop waste, food waste, and agro-industrial by-products, turning them into biogas. The biogas is then used in clean energy production to generate electricity, heat, and fuel. The by-products of biogas generation serve as fertilizers or valuable soil amendments.
