Residents in West Dereham have been advised to keep their windows and doors shut after a fire broke out at a recycling centre in the village this morning (Monday, January 16).
Crews responded to reports of the incident at Glazewing on Station Road at around 3.30am.
Three appliances will remain on site for the rest of the day to monitor the situation.
Around 500 tonnes of waste are ablaze, but a spokeswoman for Norfolk Fire and Rescue Service confirmed that it is contained at the moment.
Environment Agency officers are on site and attended a multi-agency meeting with representatives from Glazewing, Norfolk Fire and Rescue Service, and West Norfolk Council to assess the situation.
Firefighters are working to extinguish the fire as quickly as possible.
Air quality assessments are being carried out by West Norfolk Council officers.
Drainage from the site has been blocked to prevent contaminated water entering the local watercourses.
An investigation into the cause of the fire is currently underway.
