AD plant recycles food waste to generate biogasBuilding and civil engineering contractor Britcon has completed construction and officially handed over a new £20m anaerobic digestion (AD) plant in Widnes for food waste recycler ReFood.

The plant is the largest gas-to-grid AD plant in the UK and the second plant for the ReFood brand in the UK. It will recycle some 90,000 tonnes of commercial and domestic food waste and will generate up to 17NWhs of biogas which will be transported directly to the national gas grid to provide enough power for 8000 homes

Britcon was appointed to deliver this complex and highly specialist project in Widnes following successful completion of ReFood’s first AD plant in Doncaster, for which it was also recently appointed to deliver a £1.85m extension. The Widnes project brief included earthworks, piling operations and major structural works comprising multiple high rise, post tensioned, circular, reinforced digester tanks, receiving tanks and gas storage tanks.

Additionally, a Depackaging Building with a deep basement, numerous process structures, extensive external works — all on a live site with difficult ground conditions — were also part of the contract, together with a carbon neutral high-spec office complex.

Paul Morris, Operations Director at ReFood, said: “Once again Britcon has delivered to very exacting standards on an extremely specialist and demanding project. We are delighted that the Britcon team has completed this project on time and on budget with an impeccable safety record. Our first gas-to-grid AD plant is now operational as a showcase for both the ReFood brand and also the AD industry as a whole both in the UK and Europe."

ReFood Widnes offers integrated food waste collection and recycling services for businesses in a 50-mile radius including hotels, restaurants, cafes, bars, local authorities and retailers. A unique element to the ReFood offering is its sanitised bin swap services, which sees a full bin swapped for a clean one. As a result, businesses don’t have to clean their own bins and the sanitised ReFood bin can be used in a kitchen environment, enabling food waste to be separated at source.
