Anaerobic digestion is a method of generating clean energy by breaking down organic material to produce biogas and natural fertiliser.

There are currently over 650 operational anaerobic digestion sites in the UK.

Acorn uses agricultural material for our facilities, including crops from rotations and manure. By using only agricultural material, never food waste, we generate clean energy while avoiding unpleasant odours.

The agricultural material, fed into the facility is broken down by microbes. This produces:

• Biomethane, a green fuel which can directly heat homes;

• Green CO2, which can be used by industry to replace CO2 derived from fossil fuels;

• Natural fertiliser, which will be used on nearby farms, replacing imported artificial products.

Overall, the process uses a natural cycle by using CO2 from the atmosphere and sunlight to make a sustainable fuel.
