Crews from all over the region were drafted in to tackle the raging inferno which started on Sunday afternoon.
Around 50 firefighters and 10 fire engines were at the scene on Foley Street in the Attercliffe area of Sheffield for most of the night.
Six engines remain there this morning, including crews from Aston and Maltby.
The enormous plume of smoke loomed across the sky, drifting east over our area.
Eyewitnesses reported that they could see it from miles around, in places like Todwick, Worksop and Retford.
Tony Gilchrist sent us this photo on Sunday evening from Gateford in Worksop.
It shows the smoke still visible in the air just before 7.30pm.
Russell Freakley’s photo shows the plume near Cineworld in Sheffield at 4.40pm when the fire was still burning ferociously.
Commander Rick Rolt said the main fire had been tackled, and the crews were hoping to scale back operations.
He added: “We’re likely to be turning the plastics over and damping down for days but we’ve just got monitor jets on the fire now so we may be able to scale back later.”
“The crews have done an absolutely fantastic job.”
