West Yorkshire Fire and Rescue Service were alerted to the blaze at Omega Ingredients in Denholme, Bradford before 8am on Sunday (25 August).
Upon arrival, fire crews found 75% of a 75m2 building on fire, which had spread from an industrial oven used for burning animal waste.
Appliances from Illingworth, Fairweather Green, Bingley, Halifax, Rastrick, Stanningley, Pontefract, Bradford, Killingbeck, Huddersfield, Skelmanthorpe and Otley fire stations attended the incident.
The fire closed roads and thick pillars of smoke could be seen from a distance, as seen by one twitter user. The smoke plume and fire were put out by 1pm.
Firefighters remained at the scene for the rest of the day to damp down the site and prevent reignition.
A spokesman for the Omega Ingredients’ owner Leo Group said: “Following the recent fire at our Category 1 plant in Bradford, we are currently in the process of putting contingencies into place, and in the process of starting up our back-up plant.
“We are now working tirelessly to ensure there is no impact to the service we provide to our customers, and we would like to take this opportunity to thank them for their patience, support and understanding during this trying time.”
Food factories have been involved in a number of fires over the past eight months.
Earlier this month, six fire crews battled to put out a blaze that broke out in a food compactor unit at the Jordans Dorset Ryvita factory in Poole.
Meanwhile, last week, fire fighters rushed to a bakery factory in Wrexham after being alerted to the blaze in a one-storey production area.
