Incinerator information library

Information for Wilton 11, Wilton International, Middlesbrough

Status: Existing
Planning Region: North East
Planning Sub-Region: Teesside
Operator: Suez Environment (formerly SITA) and Sembcorp
Capacity: 500,000
Campaign Group(s): Contact coordinator@ukwin.org.uk to be put in touch with those opposing this development.
Notes: It was reported in June 2018 that the facility was officially opened [Source]. Mass-burn incinerator to burn "around 400,000 tonnes of non-hazardous office and household waste" [Source]. SITA awarded waste management contract by Merseyside Recycling and Waste Authority on the 30th of May 2013: "The 30-year contract covers the annual treatment of 430,000 tonnes of municipal waste collected from six local authorities: Liverpool, Knowsley, St Helens, Wirral, Sefton and Halton..."
