Blaze at Leeds paper recycling factory
Environment and health experts were at the scene of a blaze at a recycling plant in Leeds as fire teams tried to bring the flames under control.
Twelve engines were called to the fire at the plant on Valley Farm Road, Sturton, at 1320 GMT.
Firefighters said there was no risk to surrounding businesses on the industrial estate or residents.
Station commander Chris Kirby said environment officials were monitoring the volume of water used and smoke.
He added that about 25% of the building, which measures 50m (164ft) by 75m (246ft), was ablaze.
Although the plume of smoke was large, it was paper-based material on fire and no toxins were believed to be involved.
No-one was in the building at the time, fire officials said.
