Building on renewable energy #3 – Anaerobic Digestion

Published on 24 Sep 2020.

Anaerobic digestion is the process by which biodegradable materials are broken down in a controlled environment. Whilst being broken down, the materials emit gas (which can be used as a source of renewable energy), and produce heat (which can also be harnessed on or near-to site). The process also leaves a waste material (digestate), which can be used as fertiliser, contributing to the circular economy.
