History
The Trident Park facility was built primarily to service a 25 year PPP contract signed in December 2013 [2] by Cardiff on behalf of the Prosiect Gwyrdd (Project Green) partnership of five local authorities in South Wales ( Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly), with an anticipated input of 172,000 tonnes per annum of the total original design capacity of 350,000 tonnes per annum - receiving additional residual Commercial Waste.
In December 2025 Equitix increased their stake in Viridor with a path to acquire 50% of the business[5].
