Decoy Farm AD and Compost Facility


Decoy Farm site is set in a rural location between the villages of Cowbit (5km to the North) and Crowland (4km to the South) at Decoy Farm, Spalding Road, Crowland, Lincolnshire, PE6 0LX.  It is Material Change’s largest processing centre with a throughput of 45,000 tonnes of waste per year as well as a 2.8MW Anaerobic Digestion Plant located adjacent to the compost site which is operated by Material Change.


Compost Site

The majority of the waste received at the open windrow compost facility is green waste from local authorities and their contractors.  The site also composts fruit and vegetable waste.  After shredding, the waste is placed into windrows to sanitise and stabilize. After stabilisation, the compost is screened to produce a variety of compost products.  All oversize is re-processed.  The duration of the composting process on site is controlled by compliance with the Sanitisation and Stabilisation requirements of PAS:100 but is generally 8 weeks on20mm and 12 weeks on 10mm.

The compost site operates to PAS:100:2011 and the Compost Quality Protocol and produces two grades of material (20mm) for agricultural benefit and 10mm for landscaping/soil conditioning purposes. The site has agricultural fields on all sides, which receive compost applied for agricultural benefit.

Our Decoy compost is a soil improver and excellent source of major nutrients such as phosphate, potash, magnesium, sulphur, manganese – and trace elements. Each tonne of Decoy PAS:100 0-20mm compost is worth £4.54/t in crop available nitrogen, total phosphate, and total potash. An application of 33.3 t/ha will supply around £151/ha of tangible value; but the true value to soils is gained from the 7.35t/ha of longer lasting organic matter added.  A more detailed information sheet is downloadable here.

AD Facility

Material Change operates the 2.8 MWe/hr CHP Anaerobic Digestion plant at the site (owned by Decoy Farm Power Limited) that treats 50,000 tonnes per annum of grown crops. The plant is now in the final stages of commissioning, achieving 85% of the targeted power output for the last quarter. The plant has great relationship with local growers to provide the feed stock and spread the digestate. We are currently building a 8500m3 end storage tank. This extra storage capacity will enhance plant operations and help us to efficiently provide the required fertiliser to our growers.  A waste processing front end is planned for the near future.
