How to Make Biogas [Video]
Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Comprised primarily of methane and carbon dioxide, biogas originates from biogenic material and is a type of biofuel. It’s a product of the anaerobic digestion or fermentation of biodegradable materials such as manure or sewage, and can be used in CHP plants.
Most biodegradable organic material can be collected and used for anaerobic digestion.
The material is fed into a digester tank where it’s broken down by bacteria in the absence of oxygen.
This produces biogas (a renewable natural gas) which is cleaned, compressed and sent to a CHP Plant.
It also produces ‘digestate’, which can be used as a compost or biofertiliser.
