Firefighters have worked through the night to tackle a large blaze at a recycling plant in Co Meath.
A fire broke out at Panda Waste at around 11.30pm on Thursday.
It is understood there were no injuries at the plant, near Slane, which is home to around 250 of the company's 440 workers.
Extensive damage has already been caused to the premises but eight fire crews managed to contain the blaze to the buildings on the recycling campus.
It is believed there are highly combustible materials kept at the site, including refuse-derived fuel.
Gardai have warned motorists of poor visibility caused by smoke from the blaze.
Panda Waste has three premises in counties Louth, Meath and Dublin. It produces fuel by recycling waste.
The company, which is the largest exporter of recycled material in the country, says it turns over around 70 million euro a year.
