Firefighters remain at the scene of a huge fire in Saltney - almost two days after the blaze was reported.
The fire service said dealing with the aftermath of the fire could be a “lengthy process” after tonnes of recycled waste at a unit on River Lane Industrial Estate caught fire at about 8am on Tuesday.
At the height of the blaze, about 30 firefighters from eight crews were at the scene.
They were pumping water from the River Dee to deal with the fire and damp down the building which has been left heavily damaged.
Crews from Holywell and Deeside, the Aerial Ladder Platform from Rhyl, the High Volume Pump from Llandudno, and the Environmental Protection Unit from Wrexham are all in attendance this evening.
NWFRS said an investigation into the cause of the incident is expected to start once the incident is over.
Yesterday, residents had seen thick plumes of smoke billowing into the sky at the industrial building on the site of Lancashire Fuels in River Lane.
The cause of the blaze has not yet been confirmed.
Ian Williams of North Wales Fire and Rescue Service said: “We are dousing the shredded waste with water and using mechanical diggers to drag the waste from the building, allowing us to dampen down the materials.
“Due the quantity of material involved in the fire, this is expected to be a lengthy process. Residents and visitors to the area do not need to be alarmed as the fire is under control and we have the resources in place to manage the incident effectively.”
Lancashire Fuels 4 U Ltd had a planning application to turn recycled waste into biomass fuel granted by Flintshire council last month, although they require a permit from Natural Resources Wales before the process can begin.
The company arrived at the old Bostik’s plant at the end of last year and began bringing in a “substantial amount” of waste material with the local authority receiving odour complaints, according to the council report to the planning committee.
County councillor for Saltney Stonebridge, Veronica Gay, said she was “extremely concerned” by the incident and wants the authority to look into how the site is managed.
She added: “I’ve been down to the site twice today (Tuesday) and the firefighters told me it will be a two or three day operation.”
David Lee of Natural Resources Wales said: “Our officers are continuing to work with North Wales Fire and Rescue Service and the site owners to minimise the environmental impact on the nearby River Dee.
“A very small amount of fire water – the water used to fight the blaze - is entering the Dee but the small volumes means any impact will be minimal.
“There may be local impacts in the area such as a smell of smoke and some discolouration of water but again these are minimal and will have little or no impact on the environment.”
John Jones, who works at nearby Geotechnics, said: “I initially saw the black smoke then someone shouted that there was a fire.
“It didn’t take long to get going. We could see flames coming out of the side and the roof. It’s badly damaged.
“The firefighters were here quite quickly.”
In total yesterday, there were five fire engines - two from Deeside, two from Cheshire and one from Flint - along with the aerial ladder platform from Wrexham, the high-volume pump from Llandudno and the incident command unit from Rhyl.
