Firefighters battled a huge blaze at a waste incinerator site in Dewsbury this afternoon.
Crews were first called to Weaving Lane, Thornhill Lees, just before 2pm today.
Hundreds of tonnes of household waste were burning at the Kirklees Council site, sending thick plumes of smoke into the air.
Five pumps and an aerial appliance were initialy dispatched to help bring the fire in a single storey building under control.
Around 40 per cent of the building, which is approximately 160 sq m in size, was alight.
As the scale of the task became clear, a further five pumps and another aerial appliance were drafted in.
In the region of 60 firefighters were involved at one stage, with support teams also on site.
Efforts initially focused on stopping the fire spreading to offices and nearby buildings.
A spokesman said the fire was now under control, but five pumps and one aerial appliance were expected to be on site throughout the night.
