Information for Staffordshire ERF, The Dell, Enterprise Drive, Four Ashes near Cannock
Status: ExistingPlanning Region: West Midlands
Planning Sub-Region: Staffordshire
Operator: Veolia
Capacity: 340,000
Campaign Group(s): Staffordshire Against Incineration (SAIN)
Notes: Plant officially opened in May 2014 [Source]. Government Office for the West Midlands granted planning permission in January 2010 and Staffordshire County Council approved a revised plan in February 2011 [Source]. Veolia were chosen as preferred bidder to build and operate the site. In August 2010 Warwickshire County Council entered into a 25 year contract with Veolia [Source]. It was reported in May 2014 that: "Staffordshire county council will be supplying about half the waste to the facility...At present additional municipal waste is coming from other authorities including, Warwickshire, Stafford borough, Sandwell, Walsall, Wolverhampton and Shropshire" [Source].

Environment Agency Compliance Assessment Reports
Click here to see the incinerator compliance documents for existing English incineratorsStandard 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.
