Dublin Fire Brigade say two fire engines are still on the scene of a fire at a recycling centre near Rathcoole.
Earlier flames and a huge plume of black smoke were visible from the N7 motorway.
Meanwhile, residents who live near the Greenogue Recycling Centre were warned to close their windows as a precaution.

The alarm was raised just after midnight.
Fire fighters wore breathing apparatus as they tackled the flames on Tuesday morning.
Six units were originally sent to deal with the blaze, alongside a water tanker and a foam tender.

The Kildare Fire Service also sent two water tankers to assist.
The Dublin Fire Brigade say material is being hosed down as it is removed and separated.
"This will continue as we damp down and extinguish hotspots", it adds.
