Three appliances and crews from West Ashland, two from Broughton, one from Newport Pagnell, one from Aylesbury and four officers attended. Everyone in the building was accounted for.
Firefighters used four main jets, four sets of breathing apparatus, a turntable ladder and four fans. On-site machinery was used to remove waste from the building.
The incident started to be scaled down at about 4am. Relief crews arrived to continue turning over waste and damping it down during the day.
