The shortlist for a major waste treatment contract in North Wales has been cut down to two final firms, Sita UK and Wheelabrator Technologies.
The North Wales Residual Waste Treatment Project Joint Committee selected the firms for the contract to build and operate a new 150,000 tonne residual waste facility for the regions, from the trio of companies vying for the work, which included Veolia ES Aurora.
The original eight bidders for the £800m contract were cut down to three in April last year.
The partnership, between Flintshire, Isle of Anglesey, Conwy, Denbighshire and Gwynedd councils, said that proposals for the 25-year project must use proven technology, ensure that as much household waste as possible is transported to the facility by rail, and be of a proportionate size to mainly receive residual household waste from the five counties.
It must also provide air quality monitoring of a standard higher than normal industry standards to assure the public over safety of any emissions from the facility.
The winning bidder will be selected next year with the facility expected to be operational by 2017.
