History
The Ardley facility was built primarily to service a 25 year PPP contract signed in March 2011 with Oxfordshire County Council, with anticipated total throughput of up to 326,000 tonnes per annum - receiving additional residual Commercial Waste and some Household Waste from other local authorities.
It is located on Viridor's Landfill near Bicester, close to the M40, and with the opening of the facility Viridor announced the closure of the adjacent Landfill in 2014.
In December 2025 Equitix increased their stake in Viridor with a path to acquire 50% of the business[3].
