Notes: SRF-burning incinerator. It was announced in March 2017 that Wheelabrator intend to modify their facility and that this would require a Development Consent Order [Source]. It was announced in July 2016 that construction was due to start in August 2016 to begin operations in 2018 [Source]. E.ON/Wheelabrator’s bid was to build an incinerator at a facility which would also take material from the nearby mill [Source]. Planning permission for the facility was granted in September 2011 [Source]. After Veolia pulled out, E.ON/Wheelabrator was the remaining bidder for the North London Waste Authority contract to manage 250,000-300,000 tonnes of anticipated municipal waste [Source]. The previous NLWA procurement was through PFI but funding was withdrawn by the Government in October 2010 [Source]. NLWA procurement abandoned in September 2013 [Source]. Allocated Round One Contracts for Difference funding in February 2015 [Source]. The project is financed with an 18 year loan from the GIB and others [Source]. Permit SP3431KJ issued in July 2011. In September 2019 an Environmental Permit was made seeking to increase permitted capacity from 550ktpa to 657ktpa, and in August 2020 this was approved (EPR/JP3135DK/V004, Source).

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 waste wood or dedicated biomass incinerators then please see the Biofuelwatch map of UK Biomass Power Stations.

Please be aware: There is always room for improvement, so please send updates to 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.
