Viridor announced as preferred bidder for Prosiect Gwyrdd


The Prosiect Gwyrdd Project Board has announced that Viridor is its preferred bidder to treat its residual waste.

This decision will now be debated by each of the councils involved in the partnership. These are Caerphilly, Cardiff, Monmouthshire, Newport and Vale of Glamorgan.


Residual waste will be treated at Viridor’s energy from waste plant at Trident Park in Cardiff. Prosiect Gwyrdd will provide an average of 172,000 tonnes of waste to the 350,000 capacity 30MW facility. Viridor is currently in discussions with an energy supplier to provide a heat network for local properties.

Prosiect Gwyrrd senior responsible officer Andrew Kerr said: “To divert waste from landfill has significant environmental benefits and in line with Welsh Government Policy and European legislation, a solution needs to be developed for waste which cannot be practically recycled or composted.

“The project advertised on a technology neutral basis, with specific emphasis on the need to divert waste from landfill and energy from waste was the only solution proposed to the partnership.

“This partnership will ensure that a significant amount of waste is diverted from landfill, after recycling and composting targets are met so the partner authorities can meet the waste requirements set out in law by the Welsh Government.”
