Suez-Semcorp EFW

Summary

An EfW facility based upon conventional combustion technology and considered an ERF based on its R1 status. Wilton 11 has a permitted operational capacity of 500,000 tonnes per annum, and is owned by a joint venture between Suez and Sembcorp and operated by Suez. Delivery of waste is primarily by rail and the facility processes primarily residual Household Waste and some Commercial Waste.

History

The Wilton 11 facility was built primarily to service a 30 year PPP contract signed in April 2013 with Merseyside , with anticipated input of 440,000 tonnes per annum i.e the majority of the tonnage. Residual Waste is loaded at Knowsley Rail Transfer Station prior to its transport to Wilton 11. It was formally opened in June 2018 . It is located in Teeside on the Wilton International Industrial Estate and is discrete from Wilton 10 which is a Biomass Waste EFW project.

Plant

Built by CNIM and Clugson construction started in 2014 and was completed in 2016 at a reported £250m capital cost, generating 49 MWe and steam for the adjacent Sembcorp site, although the listing does not show it to be a CHP plant. The finance and delivery was under a build, own, operate and transfer contract with Merseyside.

Local Authority Data

The table below lists those local authorities who have recorded their tonnage on WasteDataFlow as sending their Waste to this site (either directly or via a transfer station) for the most recent financial year, data was updated on 2023-04-26. The tonnage received cannot be directly compared with the stated historical tonnage received and recorded in the EA statistics as these are recorded on a calendar year basis (i.e. January 2018 to December 2018). The total Local Authority waste received by the plant in the period was: 463,120.76t

A 'zero return' or a below expected return, when compared to the EA Data below indicates that either:

• no local authority tonnage was recorded/no tonnage was sent to the site in the period (but has been listed as it may have previously received tonnage from a local authority) or
• a result of the plant being recently commissioned and actually having received no tonnage or
• a lower than expected tonnage maybe a result of a local authority splitting their tonnage over multiple sites, having less tonnage to send than might be anticipated or
• it may be a new plant being in 'ramp up' towards full capacity after construction or
• may be a result of plant shut down and subsequent re-start in a year or
• the local authority may not have correctly entered the site's details on WasteDataFlow

Waste Tonnage, By Origin

The table shows a list of the Waste for the Permit XP3436WB, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated on October 2024. The total reported tonnage arriving at the site was: 417,508.81t.

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.
