How biogas works
From the Video: 1. Most biodegradable organic material can be collected for anaerobic digestion. 2. The material is fed into a digester tank where bacteria break it down in the absence of oxygen. 3. This produces biogas (methane), which is cleaned, compressed, and sent to a CHP plant. 4. It also produces a digestate, which can be used for compost or as a fertilizer.
