Energy-from-waste specialist Wheelabrator has been named as the preferred bidder for the North Wales Residual Waste Treatment PPP Project.

A statement released on behalf of the five councils on 11 April 2014, read:

All five local authorities within the partnership have individually approved the appointment. The North Wales Residual Waste Treatment Project (NWRWTP) is a partnership between Gwynedd, the Isle of Anglesey, Conwy, Denbighshire and Flintshire County Councils, formed to divert non-recyclable household waste from landfill.

Wheelabrator had been the only remaining bidder for the contract after SITA UK abandoned the procurement process after saying that because of the current economic climate, the project ranked lower than other opportunities.

The project will be backed with £142.7 million funding from the Welsh Government in the form of a £5.72 million subsidy each year over the service period of the contract. It will represent a total investment of around £700 over the lifetime of the project, which is estimated to be around 25 years.

The proposed facility will treat around 150,000 tonnes of residual household waste from the five counties per year, in line with the Welsh Governments target to recycle 70% of all waste by 2025.

It is expected that the partnership will finalise the details of the contract by the summer, when Wheelabrator will also begin consulting with local residents on the new facility, with the intention to submit a planning application later in 2014.
