A spokesperson for Nottinghamshire Fire and Rescue Service said they were called to the fire at around 10.23am, and firefighters from the service as well as neighbouring Derbyshire Fire and Rescue and South Yorkshire Fire and Rescue have been battling the blaze all day.
An estimated 1,000 tyres and scrap vehicles have caught fire, and huge plumes of black smoke have been seen throughout Doncaster, Rotherham and in some parts of Sheffield this evening.
Area Manager Andy Macey, incident commander, said: "Thank you to our partners in Derbyshire, Lincolnshire and South Yorkshire fire and rescue services for their support.
"We ask the public not to gather near the scene as they put themselves at risk and hinder us in our work.
"We’re likely to be on scene for some time so we thank the public for their patience."
