Slurry from a Scots farm running an AD-power (anaerobic digestion) scheme has helped the developer scoop a UK industry award.
Biogest was awarded the prize for “Best international micro-scale plant” for its Biogest Power Compact technology, specially designed for dairy farms, operating on 100% slurry at the Littleton Farm in Dumfries-shire.
Power Compact biogas plants with an electric supply of 100–300 kW have certain advantages concerning plant operation, energy efficiency and operation safety.
Currently, four Power Compact biogas plants – built and financed by Biogest – are in operation in the UK. They are operated by partners in the agricultural sector and supported by Biogest technically and with regard to biological issues.
One of these plants was built at Littleton Farm – a traditional family company with over 100 years of experience. The farm’s main sector of activity is the production of milk, with a stock of more than 1,500 milk cows.
Sustainable environmental protection is an important issue at the farm, and other forms of renewable energy, such as solar and wind energy, are also used in addition to biogas.
The biogas has 124 kW electrical capacity and is able to cover not only its own energy needs, but also to supply approximately 370 households with energy, by feeding in to the public net-work.
Thermal energy is used for drying sawdust and woodchips. The plant is fuelled exclusively with slurry, which, after processing within the biogas plant, is available as high-quality ecologic fertilizer.
