A site in Cardiff has been recommended as the preferred place for five councils in south east Wales to dispose of their non recyclable rubbish.
The waste will be sent to an incinerator in the Splott area of the city.
The 25 year contract will cost the councils around £440m, with the Welsh Government paying 25% of the cost.
The contract would begin on April 1st 2016.
The recommendation will now go to councils for approval.
