Crews remain on the scene of two fires in Rushton and Northampton.
Firefighters were called to a fire at a waste transfer station in Oakley Road, Rushton, at 10.28pm, and to a factory fire in Studland Road, Northampton, at 11.54pm yesterday, Tuesday, July 23.
This morning, Wednesday, July 24, two appliances remain at the ongoing Rushton fire, which involves a large quantity of recycling waste.
Northamptonshire Fire and Rescue Service (NFRS) personnel are expected to remain on scene for the next 24-48 hours.
A national waste fire tactical advisor is also present to assist the NFRS incident commander, and partner agencies, including the Environment Agency and public health services, are aware of the fire.
Once the firefighting operation is concluded, an investigation will be carried out into the cause of the blaze.
Two appliances also remain on the scene of the Northampton factory fire to allow crews to deal with remaining hotspots within the single-storey building.
Damping down work is expected to continue until the early afternoon at least, and the cause of this fire is under investigation.
Smoke plumes from both incidents are now reduced, and the wind direction is being monitored.
Residents of any properties affected by any residual smoke from either fire are advised to continue to keep windows and doors closed.
