Anaerobic Digestions is a natural process in which micro-organisms break down organic matter in the absence of oxygen into biogas and digestate.
Typical feedstocks for farm scale systems are manures and slurries, vegetable waste, dedicated energy crops or imported materials such as draff or distillery waste. The biogas can be used as a fuel for boilers and gas engines or upgraded and fed into the local gas network or used as vehicle fuel. The remaining digestate can be spread back to land as a fertiliser.
