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.

Step 1:

Most biodegradable organic material can be collected and used for anaerobic digestion.

Step 2:

The material is fed into a digester tank where it’s broken down by bacteria in the absence of oxygen.

Step3:

This produces biogas (a renewable natural gas) which is cleaned, compressed and sent to a CHP Plant.

Step4:

It also produces ‘digestate’, which can be used as a compost or biofertiliser.
