KIRK UK completes ground-breaking AD plant in silloth, Cumbria
KIRK UK, part of KIRK GROUP, pushed the boundaries for its role as Main Contractor when they also took on the responsibility of CDM Co-Ordinations at Farmgen’s ground-breaking Anaerobic Digestion (AD) Plant built at the Dryholme Farm in Silloth, Cumbria.
The farm has been operating for over 20 years with its core business being the production of animal and poultry feeds. When Farmgen was considering the future of Dryholme Farm they knew that some type of diversification was necessary to further develop the already successful business.
The Anaerobic Digestion process fit the business model perfectly by being able to utilise the waste animal and poultry feeds into a source of renewable energy. The key infrastructure of the plant consists of three 3,000 tonne Glass-Fused-To-Steel AD Tanks complete with the industry-leading BIODOME® Double Membrane Roofs. The biogas that is produced as part of the AD process is captured in the BIODOME® Roofs before it is cleaned and sent to the CHP Unit, which works as the engine of the plant, where electricity is produced for exporting to the National Grid.
The plant uses grass and maize silage grown on farm and in the surrounding area to produce 1.2MW of electricity, enough continuous power for more than 2,200 homes, producing a significant boost to Cumbria’s rural economy and contributing to the business as a whole.
The partnership approach, with KIRK UK carrying out all Engineering, Construction and Project Management functions and Farmgen providing the critical Process Design Technology for the AD facility, limited the number of interfaces that had to be managed, leading to a very efficient decision making process at the front end and, as the plant progressed, allowing changes and improvements to be made with the minimum of impact to cost and programme.
