The products of AD are referred to as biogas and digestate. Biogas is a mixture of 60% methane, 40% carbon dioxide and traces of other contaminant gases. The exact composition of biogas depends on the type of feedstock being digested.

Biogas can be combusted to provide heat, electricity or both. Alternatively, the biogas can be `upgraded` to pure methane, often called biomethane, by removing other gases. This pure stream of biomethane can then be injected it into the mains gas grid or used as a road fuel. For more information on biogas please use the links on the right hand side of this page.

Digestate is made from left over indigestible material and dead micro-organisms. It contains valuable plant nutrients like nitrogen and potassium. It can be used as a fertiliser and soil conditioner. For more information on digestate please use the links on the right hand side of this page.
