| Total Waste Combusted Year Total | 21,990.00 | Household / Local Authority (92.87%) |
| NCV Year Total | 37,500.00 | |
| Permit Breaches Year Total | 19.00 | |
| Annual CO2 Mass | 23,893.20 | This was calculated using data for CO2 from the stack analysers for the year 2025, as the CO2 data provided from the analyser was dry, A correction factor using a moisture content of 17% for the wet reading, the total figure was then calculated according to running hours and stack flow. |
| Annual CO2 Mass Per Tonne | 1.09 | |
| Annual CO2 Mass Per Mwh | 0.47 | |
| Annual N2O Mass | 13.75 | Using the figures from the H1 (1837 g/hr) & H2 (1845 g/hr) compliance testing which were added together and divided by 2 giving a figure off (1841 g/hr) was then multiplied by the plant running hours which gave a figure of (13754111 g/hr) converted to tonnes giving 13.75 tonnes. |
| Total CO2 N2O | 27,536.95 | |
| Biogenic CO2 Percentage | 0.50 | This is the upper level of an estimated figure which states 33 to 50% , as ERP processes all of Shetland and Orkneys MUN waste after recycling. |
| Biogenic Percentage NCV | 0.60 | This is an estimated figure from industry data. |
| Biogenic Percentage Mass | 0.60 | This is an estimated figure from industry data. |

Environment Agency Compliance Assessment Reports
View the full UKWIN incinerator compliance indexStandard 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.
