The anaerobic digester system at Birks Farm was brand new when it opened during last year’s Green Build Festival and had not yet been commissioned. This year’s event offers an opportunity to find out about its performance over the first year, as well as to hear about a related project, a wood gasifier to be deployed in Sedbergh.
The anaerobic digester system was built with less than £200,000 capital by a local building contractor (G J Baines & Son). Four bays operate on 60-day shifts and the biogas captured feeds the combined heat & power unit, with an output of around 40kW.
By using the heat within the Birks Farm agro-forestry enterprise and exporting the electricity to their neighbour, JMP Foodservices, the capital will be repaid in less than 18 months.
Benefits to the farm include:
- using all of the waste from the 150 acre cattle, beef & sheep;
- shelter from impending livestock emissions taxes;
- no more artificial fertilisers; and
- it's energy independent, economically viable without support from the Single Farm Payment.
BJC-UK (Estates) Ltd have hosted the development of the system, which is a new concept for on-farm anaerobic digestion in the UK. It is based on a design by French company Aria, integrated by Quanta Systems and powered by a UK-manufactured combined heat & power unit that was designed and built by Mayphil Engine Group.
Please note that this is a working farm and appropriate footwear should be worn.
