Dunbar EfW (Oxwellmains EfW)
An EfW facility based upon conventional combustion technology which as yet does not have R1 status. Dunbar has permitted operational capacity of 300,000 tonnes per annum, operated and owned by Viridor. Delivery of waste is by road and rail and the facility processes primarily residual Household Waste and some Commercial Waste [1] mainly in the form of a prepared RDF

Summary
An EfW facility based upon conventional combustion technology which as yet does not have R1 status. Dunbar has permitted operational capacity of 300,000 tonnes per annum, operated and owned by Viridor. Delivery of waste is by road and rail and the facility processes primarily residual Household Waste and some Commercial Waste [2] mainly in the form of a prepared RDF
History
The Dunbar facility was built to service Scotland's residual Household Waste and Commercial Waste and includes RDF from its contract with Clyde Valley in May 2016 which processes 190,000 tonnes per annum via Viridor's Bargeddie site in North Lanarkshire (which opened in January 2020). It is located in East Lothian on Viridor's Landfill site which is due to close with the operation of the facility, which commenced in January 2019.
Plant
Built by a JV between Interserve and Babcox & Wilcox Volund A/S as a turnkey EPC contract, which started in 2015 and was delivered in January 2019 at a reported [3] £177m capital cost. The plant comprises 2 lines via standard combustion B&W Volund proprietary Dynagrate technology, generating super-heated steam, and is configured to run on primarily residual Household Waste and similar residual Commercial Waste with design capability up to 320,000 tonnes per annum based on a prepared WDF fuel CV of 10MJ/kg[4].
Local Authority Data
The Residual EfW pages for sites located in England and Wales capture the data reported by Local Authorities, through WasteDataFlow, received at those sites. In Scotland this data is not reported, meaning that the destination in WasteDataFlow is not defined and the origin in the regulator returns for a facility receiving the tonnage is also not reported (resulting in a 'NA' in the table in the section below). As a result it is not possible to report for Scottish sites in the same way as other sites in WikiWaste.
Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit PPC/A/1032878, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2023. The total reported tonnage arriving at the site was: 164,941.46t.
Where this tonnage exceeds that reported in year of the corresponding annual report, this may be due to the following reasons:
- Tonnage may have been received but not incinerated, i.e. the material is held pending incineration (the operator return to the EA reports as received whereas the annual report focuses on when the waste is incinerated.)
- Material may have been received into the site but treated in some other way than incineration.
- Material may have been received on the but transferred out of site for disposal/treatment at another site rather than incineration on the site.
