What is anaerobic digestion?

Anaerobic digestion (AD) is a sustainable process where organic matter, such as food or plant waste, is broken down by micro-organisms called methanogens in the absence of oxygen. This creates biogas (a mixture of methane and carbon dioxide) which we can use as a source of energy. 

This process also creates a bio-fertiliser by-product. This is rich in nutrients such as nitrogen, potassium, and other elements, and can be used in agriculture or horticulture as liquid fertiliser, or even animal bedding, as part of the circular economy.
