Information for Greatmoor EfW, Lower Greatmoor Farm, Edgcott, Aylesbury (near Calvert)

Status: Existing
Planning Region: South East
Planning Sub-Region: Buckinghamshire
Operator: FCC (Formerly Waste Recycling Group) and Green Recovery Projects (GRP) / ICON
Capacity: 345,000
Campaign Group(s): Wycombe Labour for a Green New Deal and Buckinghamshire Residents Against Incinerators (BRAINS) and Bucks Environmental Strategy for Treating Waste (BestW)
Notes: The facility was reported to have taken its first waste load in February 2016 and was reported to be fully operational in July 2016 [Source, Source]. The planning committee resolved to grant permission on 20th April 2012 (ref 11/20000/AWD, submitted February 2011) [Source]. WRG/FCC were named as the preferred bidder in November 2010 for Buckinghamshire County Council’s Waste PFI and included the Aylesbury site in their bid. The 30-year contract to build and operate the facility was awarded to FCC in July 2012 [Source]. (Entry updated 2020-09-17)

Environment Agency Compliance Assessment Reports

Click here to see the incinerator compliance documents for existing English incinerators

Standard notice:

UKWIN (and therefore the UKWIN map) focuses on Municipal Waste Incinerators, whereas our colleagues at Biofuelwatch focus on biomass projects. If you are interested in biomass incinerators (including waste wood plants) over 20MW then please see the Biofuelwatch map of UK Biomass Power Stations. Those concerned about biomass plants, including waste wood plants, should email Biofuelwatch at biofuelwatch[at]gmail.com.

Please be aware: There is always room for improvement, so please send updates to coordinator@ukwin.org.uk. Existing Incinerator means a facility that is operational or under construction/commissioning. A Potential Incinerator is a facility where there is a proposal for an incinerator (e.g. planning application or planning consent) or other reason to believe an incinerator might be built/proposed in the future. A Prevented Incinerator is something which used to be a proposal or expected incinerator which we do not believe is currently being progressed (e.g. because the project was cancelled, planning permission refused, or years have gone by since the permission was granted without any progress) - in some cases a facility marked as prevented is being progressed without us being aware or is subsequently revived. Capacity is usually the permitted or maximum advertised capacity of the facility.
