An AD plant with piling of the tanks and concrete secondary containment

The AD plant at Decoy Farm, Crowland near Peterborough in Cambridgeshire, UK was fully commissioned in early 2016 and generates 2.8 MW of electricity which is sufficient to power approx. 6,000 homes.

The construction site in a polder required extensive piling and a secondary containment of concrete to protect the groundwater against any potential spills. As a consequence, all piping was above ground and required additional measures against frost protection. The close cooperation between Agraferm and the construction companies was facilitated by Agraferm’s experience in managing large & complex projects, know-how in engineering, piping and machinery, as well as handling large quantities of gas and liquids.

The AD plant biology is formed by a 3-stage digestion process for consistantly high gas yields. As with the previously built AD plants, this AD plant is also characterised by its optimum outputrelativeto the space the plant takes up. This is made possible by the high dry matter organic loading rate and high degradation of the feedstock thanks to the patented agitators in smaller size tanks. Agraferm plants are also well known for their low electricity consumption and low maintenance costs.
