A materials recycling facility belonging to HW Martin Waste Management has been severely damaged by a fire.
The facility in Beeston was hit by fire at the end of July and at its height more than 12 fire engines fought the blaze at the 100m by 80m warehouse.
Opened in June 2007 at a cost of £5 million, the facility sorts waste on behalf of Leeds City Council and processes 80,000 tonnes of material each year.
It is unclear at this stage what caused the fire.
The MRF sorts recycling including plastics, cans, paper and cardboard from Leeds’ households for recycling.
Leeds City Council executive member for the environment Cllr Mark Dobson said: “Residents can be assured that none of these materials will be wasted of landfilled and that recycling remains our priority.
“We are hopeful that these contingency arrangements will not impact on collections.
“We will be working with HW Martin to get operations back to normal as soon as possible.”
