Severnside Energy Recovery Centre

An EfW facility based upon conventional combustion technology and considered an ERF based on its R1 status. Severnside ERC (also known as SERC) has a permitted operational capacity of 400,000 tonnes per annum, and is owned and operated by West London Energy Recovery Ltd a company set up for the purpose by Suez. Delivery of waste is primarily by rail and the facility processes primarily residual Household Waste and some Commercial Waste.

Suez Severnside (SERC) Site

Summary

An EfW facility based upon conventional combustion technology and considered an ERF based on its R1 status. Severnside ERC (also known as SERC) has a permitted operational capacity of 400,000 tonnes per annum, and is owned and operated by West London Energy Recovery Ltd a company set up for the purpose by Suez. Delivery of waste is primarily by rail and the facility processes primarily residual Household Waste and some Commercial Waste.

History

The Riverside ERC was built primarily to service a 25 year PPP contract signed in 2013 with WLWA , with anticipated input of around 300,000 tonnes per annum i.e the majority of the tonnage. Additional tonnage has also been secured from the West of England Partnership and Devon County Council.The Residual Waste from WLWA is loaded at two rail-linked transfer stations in Brentford and South Ruislip prior to its transport to Severnside ERC.

In January 2020 Suez requested an alteration to the facilities Environmental Permit seeking a 100,000 tonne per year increase to its processing capacity. If successful the plant will, in the future, be able to process 500,000 tonnes per year.

Plant

Built by Hitachi Zosen Inova under a Design & Build EPC-turnkey contract and was delivered in 2016 at a GBP £240m capital cost. The plant comprises 2 lines of 21.85 tonnes/hour (maximum 24.24 tonnes/hour) design capacity capable of treating 350,000 tonnes per annum via standard combustion technology, air cooled, Hitachi Zosen Inova Grate, generating super-heated steam. It is configured to run on residual Household Waste and Commercial Waste with a CV of between 7.5 and 12.5MJ/kg to deliver 37.5MWe of power . Operating at the maximum design tonnes/ hour figure would result in a capacity close to 400,000 tonnes per annum, but this would require a low CV.

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: 350,931.38t

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 ZP3937KL, 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: 403,098.11t.

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.
