Campaigners are claiming victory after plans to dispose of hazardous waste at a Teesside landfill site were rejected.
Alab Environmental Services, a division of ship-breaking firm Able UK, wanted to treat oil and sludge at the plant at Seaton Meadows in Hartlepool.
But the local council has turned down the proposal after campaigners claimed the plant would be noisy and dusty and would harm the environment.
Alab Spokesman Ian Fenney said the firm was confident it would win an appeal.
The company wants to solidify and stabilise liquid waste at the plant by trapping it in a form of concrete made from fly ash.
Mr Fenney said this method meant there was less likelihood of toxins leaking into soil and water supplies.
He said: "We are now going to have to go through the appeal process which we are likely to win and this will cost the Hartlepool taxpayer."
