Anaerobic Digestion
What is Anaerobic Digestion?
Anaerobic Digestion is a natural biological process that can be used to generate renewable energy and manage waste.
The process takes place in an oxygen-free digester, where micro-organisms convert organic material such as food waste, slurries and crop residues into: – Biogas: a renewable fuel – Digestate: a powerful fertiliser or soil conditioner
Biogas
Biogas is a mixture of biomethane gas and carbon dioxide. The biogas can be used directly in CHP engines to produce renewable heat and power, or it can be burned to produce heat only.
Alternatively, biomethane can be produced by removing the carbon dioxide from the biogas. The biomethane has many valuable uses. It can be injected into the gas grid as a renewable replacement for natural gas or it can be used as vehicle fuel.
Digestate
The by-product from the AD process is called ‘digestate’. It is rich in valuable plant nutrients such as nitrogen and potassium, and can be used as a renewable fertiliser or soil conditioner.
Agricultural Anaerobic Digestion
The benefits of Anaerobic Digestion to the farming and agricultural sector are widely recognised: Agriculture generates significant volumes of organic wastes, such as animal waste and crop wastes. Anaerobic Digestion provides an option to recover value from these wastes and reduces the overall carbon footprint of the farming enterprise.
The adoption of anaerobic digestion has many benefits to farmers:
• Additional Income and cost savings including, selling biomethane to the gas grid, producing valuable fertiliser and reduced carbon footprint, which is critical for suppliers to food retailers.
• Operational support provided by Government.
