Firefighters were this week tackling a blaze at a Waste Recycling Group facility in Suffolk 24 hours after it broke out.
Ten fire engines were called to the waste transfer facility on Homefield Road in Haverhill on the morning of Monday 27 February.
Up to 150 tonnes of rubbish was involved in the fire, which was still being attended by some crews on the morning of Tuesday 28 February.
WRG, which is owned by international infrastructure, environmental services and energy group FCC, manages 18 household waste recycling centres across Suffolk.
A spokesman for the firm said: “Until we have an opportunity to access the building and conduct our own enquiries we do not know the cause of the fire, but it is possible that it was brought to the facility within a waste load.
“We have not been able to assess damage to the building yet. Our operations will not be seriously affected as we can temporarily divert waste to other facilities.”
WRG apologised to its neighbours for the inconvenience caused by the fire and said it was working with the fire service on site.
The blaze is the latest in a series of fires at recycling sites over the past few weeks.
