Incinerator information library

Information for Cornwall EFW Recovery Centre, Rostowrack Farm, St Dennis

Status: Existing
Planning Region: South West
Planning Sub-Region: Cornwall
Operator: SITA Cornwall Ltd (Suez Environment)
Capacity: 240,000
Campaign Group(s): Cornwall Sustainable Waste Network (CSWN) and St. Dennis Incinerator Group (STIG)
Notes: Facility operational. Environmental permit granted in December 2010 [Source]. Planning permission granted on appeal in May 2011 [Source, See decision]. Permit GP3433GH issued in December 2010. SITA emissions data avilable from here and independent monitoring reports available from here. In March 2019 local campaigners were informed that repairs were being carried out to replace the faulty turbine. The turbine problem meant that no electricity was generated by the plant since June 2018 [Source]. In October 2025 it was reported that workw as due to start "on repairs to Cornwall’s waste incinerator at St Dennis, which has been out of action for months due to a very serious accident which damaged the plant’s boiler" [Source, Source].
