Anaerobic Digestion Facility

Working on behalf of W P Callander & Co, MFA successfully obtained planning permission for a large scale Anaerobic Digestion facility on a parcel of land at Crofthead Farm, Crocketford.

The dairy farm had already diversified into energy generation with the installation of 2 x 40m wind turbines as well as a small scale (124kW) AD plant which provided electricity for the farm and the proposed development was seen as the next logical step towards reducing the carbon footprint of the farm and its long term sustainable future.

The AD Plant processes up to 100,000 tonnes of slurries, cattle manure, energy crops and dairy residues and generates 8MWh electrical power equivalent of gas.  The majority of the feedstock comes from Crofthead Farm and the neighbouring farm, Auchengibbert, which is a large beef farm.  The facility produces PAS110 accredited digestate which is used as a bio-fertiliser on local farm lands.

The plant was accredited for the new biomethane RHI tariff and benefits from the government’s Feed in Tariff (FIT), which like RHI is a 20 year indexed linked subsidy that is part of the government’s programme to support renewable energy projects in the UK.

The plant was first commissioned in December 2019.
