Firefighters are expected to remain at the scene of a fire at a recycling plant in Salford for several days.
Crews were called to the fire - which involves thousands of tonnes of mixed waste - at the plant in Duncan Street, close to Regent Road just before 11.30pm on Sunday, March 2.
Smoke could be seen for miles around and six fire engines and GMFRS' Command Support Unit remain at the scene
Because of the serious nature of the fire crews worked to limit the risk of the building collapsing and stopping the flames spreading to the neighbouring businesses and railway line.
Firefighters are now cooling the outside of the building to prevent its collapse allowing the fire inside to burn out.
Group Manager Lee Coleman, said: "Because of the serious nature of this fire we could remain at the scene for several days.
We're getting on top of the fire and the smoke is going up into the atmosphere and dissipating without causing any significant problems to people.
"If the weather changes, it cools down and the smoke starts to come down please keep your doors and windows closed."
