THE cause of a major fire at a Wimblington factory still remains unknown, despite the best efforts of fire investigators.
Fire broke out in a baling building at plastics recycling factory Plasgran, on Manea Road, at 3.15pm on Wednesday.
At its height, nine crews from as far away as Gamlingay and Papworth, water carriers from Yaxley and Huntingdon, the turntable ladder from Dogsthorpe, the support unit from March, the command vehicle from Huntingdon and the hose-layer and high volume pump from Huntingdon were in attendance, with more than 60 firefighters battling the flames until it was brought under control by 11pm on Wednesday.
The blaze created huge clouds of smoke which drifted over Wimblington and prolonged road closures affected motorists, with Manea Road not reopening until Thursday night.
A fire service spokesperson said the building had sustained massive damage and part of the roof had collapsed, making an investigation into the cause of the fire very difficult.
An investigator had worked at the scene for two days but could not determine a cause. It will now be up to the insurance company if they want investigations to continue.
Plasgran thanked Cambs Fire Service, staff at the site for their efforts to keep the business running and the support received from customers and suppliers.
