Information for Severnside Energy Recovery Centre, Severn Road, Avonmouth

Status: Existing
Planning Region: South West
Planning Sub-Region: South Gloucestershire
Operator: Suez Environment (formerly SITA) (leading consortium that also includes Lloyds Banking Group and the ITOCHU Corporation)
Capacity: 467,082
Campaign Group(s): Bristol Against Mass Burn Incineration (BAMBI), FoE Bristol and West of England Liberal Democrats
Notes: In March 2020 Suez secured a variation of their environmental permit to increase the capacity from 400,000 to 500,000 tonnes per annum [EPR/ZP3937KL/V007]. In December 2016 it was reported that operations were set to begin [Source]. Intended to burn municipal waste from the West London Waste Authority (WLWA) as well as commercial and industrial waste. Granted planning permission on appeal in September 2011. [See decision document]. Environmental Permit issued by the Environment Agency. It was reported in November 2015 that "Construction started December 2013 and will be complete in August 2016" [Source]. Contract signed with West London Waste Authority in November 2013 [Source]. GBP 20m invested by Green Investment Bank in November 2013 [Source]. It was reported in February 2019 that a contract to incinerate waste from North Devon had been agreed [Source]. Permit ZP3937KL issued in July 2010. (Entry updated 2020-05-29)
