More than 80 firefighters have been tackling a huge blaze in Wellingborough.
A large pallet yard has been severely damaged during the fire.
Larner Pallets, in Wellingborough, went up in flames at about 1.30am on Sunday.
At the height of the fire, 80 firefighters from across Northamptonshire, Bedfordshire and Buckinghamshire were drafted in to tackle the blaze which consumed a large area inside the company's compound.
At least one lorry was destroyed and a number of metal containers on the site were burned.
A spokesman for Northamptonshire Fire and Rescue Service said: "This was a large fire in the open involving a large quantity of pallets spread over an area of 100 metres by 50 metres.
"It also effected six storage containers and a large quantity of wood chippings."
During the blaze, the firefighters used six ground monitors which allow water to be directed at an area using a hose which is secured in place without the need for firefighters to stand and hold it.
In addition they used three hose reels and an aerial ladder platform to deal with the fire.
The incident was attended by eight fire engines, a fire service control unit, the Fire Victim Support Unit, the fire service's UK Operational Support and a high volume water pump.
Throughout Sunday two crews of firefighters remained at the scene to damp down the remnants of the fire and smoke could still be seen coming from large piles of ash in the company's grounds.
During the operation, the road leading to the yard was cordoned off by officers from Northamptonshire police.
Larner Pallets is based in Rixon Road, in the Finedon Road Industrial Estate, and is surrounded by other companies which were uneffected.
The incident in Wellingborough is the second major fire to have hit a pallet yard in the county in less than a week.
Last Monday, eight crews from around the county battled to contain a fire in the storage yard of Alpha Pallets in Martin's Yard, off Spencer Bridge Road, Northampton.
Up to 30,000 pallets went up in smoke during that blaze which took nine hours to extinguish.
