Crews from Humberside Fire and Rescue Service were called to a fire at a biogas plant in North Cave, East Yorkshire at around 18.30hrs on Christmas Day.
Around 600 tonnes of vegetable oil were on fire at the recycling plant on Crosslands Lane. At its height, 62 firefighters and 12 engines were tackling the fire. The plant was not believed to be operational at the time and there were no casualties reported.
A foam blanket has been applied and a bund was put in place around the building housing the vegetable oil on fire. Water spray curtains were used to stop heat infringement onto other plant buildings.
Crews will remain on site throughout the night containing the fire and are likely to remain until lunchtime on Boxing Day.
Some smoke is likely to still be visible at daybreak and local residents are advised to keep windows and doors closed as a precaution. There is no indication that this smoke is hazardous.
