Information for Ardley EFW Plant, Ardley

Status: Existing
Planning Region: South East
Planning Sub-Region: Oxfordshire
Operator: Viridor
Capacity: 378,000
Campaign Group(s): Oxford FoE and Oxford Brookes People and Planet and Ardley Against the Incinerator (AAI)
Notes: Operational. In December 2017 the capacity was increased from 300,000 [Source]. Oxfordshire County Council rejected Viridor’s original application just weeks after selecting the company as preferred bidder. The developer appealed this refusal and also submitted a revised planning application in April 2010 [Source] which was approved in October 2010 [Source]. The Secretary of State issued a "minded-to" letter in December 2010 supporting a grant of permission for the original application, and he decided not to call in the revised application. Permit FP3134GU issued in September 2010. (Entry updated 2019-06-06)
