A fire at South Yorkshire-based Universal Recycling prompted a warning from police for local residents to find alternative accommodation.
The blaze broke out on the morning of 8 May, with reports saying around 500 tonnes of plastic and other materials were involved.
Eight fire engines were sent to the incident at Wharf Road in Kilnhurst. Although the fire was quickly contained, thick smoke continued to pose a serious problem.
Police cordoned off the area and chief inspector Iain Chorlton ”strongly advised” residents to make contact with family and friends to seek alternative accommodation.
The incident is ongoing and the level of smoke has decreased.
Three fire engines are still on-site and residents have been advised to keep their doors and windows closed.
South Yorkshire Fire Service tweeted: “Our crews have worked hard through the night to tackle the Kilnhurst fire. It is under control, but we expect to be there most of the day.”
