AD Today

Anaerobic digestion (AD) is a biological process which converts organic materials (such as manure, energy crops, food waste and agricultural by-products) into renewable energy in the form of biogas.

This biogas can be used to produce heat and electrical power via a CHP engine.

Biogas can also be upgraded to biomethane and injected into the gas grid or used to power vehicles, including tractors.

This biogas can be used to produce heat and electrical power via a CHP engine.

In addition, carbon dioxide created during the process can be captured and used by horticulture (in greenhouses) or by industry.

In addition, carbon dioxide created during the process can be captured and used by horticulture (in greenhouses) or by industry.

The AD process also produces an organic biofertiliser called digestate.

AD helps reduce agricultural greenhouse gas (GHG) emissions in the following ways:

  • Prevents uncontrolled emissions of GHGs including methane, nitrous oxide and CO2
  • Displaces fossil fuels with renewable energy
  • Displaces the use of fossil-derived fertilisers with digestate
