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.
