The Official Information Portal on Anaerobic Digestion

This website was created in 2009 as an independent authoritative resource on all things AD. Creation of the site was supported by Government and industry. The site was developed and is maintained by NNFCC.


Anaerobic digestion (AD) is the breakdown of organic material by micro-organisms in the absence of oxygen. AD produces biogas, a methane-rich gas that can be used as a fuel, and digestate, a source of nutrients that can be used as a fertiliser. Increasingly AD is being used to make the most of our waste by turning it into renewable energy.

AD benefits many different groups; including the local community, industry, farmers and energy entrepreneurs, government and the environment.

Explore this website to understand the process, the benefits and the value to you.
