A fire broke out over the weekend at Recycling Lives on Rough Hey Road Industrial Estate in Preston.
Recycling Lives operation had a large number of vehicles at its facility and it is understood that around 200 tonnes of cars and metal were caught in the fire.
Thick black smoke was seen coming from the industrial estate due to the material being burnt, and people living nearby were urged to stay indoors and keep their doors and windows closed.
The smoke also caused problems for motorists, as plumes of smoke blew onto the M6, and firefighters advised motorists to be extra careful when driving in the area.
Initially, six fire engines were sent to the scene, but later this was increased to 10. The response also included two aerial ladder platforms.
At the time a spokesman for Lancashire Fire and Rescue Service said:
“A Lancashire Fire and Rescue Service spokesman said: “We have 10 fire engines at the scene along with two aerial ladder platforms. Firefighters are working alongside on-site crews to extinguish the fire. The fire involves approximately 200 tonnes of pre-shredded cars and metal. The High Volume Pump from Burnley has arrived at the scene to help increase the volume of water in the incident ground.”
