PlanET Biogas wins contract to build 500kW AD plant in UK
PlanET Biogas UK has been contracted as technology provider for a 500kWel anaerobic digestion (AD) plant in Shropshire, UK.
The Bitterley Biogas AD plant, to be situated near the town of Ludlow, will be fed predominantly cattle manure from surrounding farms.
Excavation and concrete works for the digester have been completed and commissioning is planned at the end of September 2016.
“At full capacity, the combined heat and power plant will supply clean and renewable energy for about 1,000 households in the area. Beside this aspect, I am really pleased to improve our farm’s fertiliser management by digesting existing agricultural residues and recycling nutrients,” said Mark Gatehouse, the future operator of the facility.
The state-of-the-art AD plant will process 9,000 tonnes of manure and 4,000 tonnes of crop-based feedstock.
It consists of a solid feeding container with advanced maceration technology to pre-treat longer straw fibres.
The heated in-situ concrete digester is equipped with a gas-tight membrane air-supported roof and adjustable mixers.
After separation of solids, a pump recirculates liquids into the digester so that no additional water will be necessary.
In future the excess heat of the CHP will be used for drying digestate, and the product will be sold or applied as fertiliser on the fields.
Through the reduction of volume, the spreading of digestate will be consuming less fuel and thus further contribute to CO2 savings.
