Viridor to be preferred bidder for Prosiect Gwyrdd contract


Viridor’s energy from waste plant at Trident Park in Cardiff looks set to handle the waste from five South Wales councils once it is completed.

All five local authorities involved in the Prosiect Gwyrdd partnership have agreed to the Joint Committee’s recommendation that Viridor should be appointed the preferred bidder for the 25-year residual waste contract with the possibility of a five year extension.


Viridor is expected to be formally appointed preferred bidder over the coming weeks with contract award planned for the end of June.

This means that the merchant plant that Viridor is currently constructing in Cardiff will handle the residual waste from Caerphilly, Cardiff, Monmouthshire, Newport and Vale of Glamorgan councils.

Prosiect Gwyrdd chairman of the Joint Committee Cllr Russell Goodway said: “This partnership is set to be one of the most significant partnerships between the public and private sector in Welsh history.

“It has been a long process, but it is a very complex project, which will ensure that all five local authorities have a very good value, reliable and environmentally sustainable means to treat non recyclable waste for the next 25 years.

“The new Joint Committee which was formed following the May local elections has ensured that the project has been scrutinised in detail and the cost savings to the partnership are £500 million as compared to landfill over the 25 year contract period.

“It is now time to finalise the agreed terms with Viridor and while this process starts, the project team continues to engage with residents to ensure information is available and any questions or concerns can be addressed.”

Viridor business development director Howard Ellard said: “After a three-year tendering process, we are pleased that the partnership councils have agreed to the Joint Committee’s recommendation that Viridor should be appointed preferred bidder.

“We look forward to working with Prosiect Gwyrdd to finalise the necessary details to allow commencement of this essential service for the project partners and their residents.”
