Evansville Fire Crews were called to a recycling warehouse Saturday morning.
Officials say they were called out shortly before 3:30 a.m. to Tri-State Resource Recovery on Harriet Street.
We're told crews found a large pile of paper and cardboard in the middle of the warehouse.
Fire officials say the fire was contained within an hour, but overhaul continued for a few more hours due to the smoldering bundles of compacted cardboard that was involved.
EFD says the fire is still under investigation, but the cause will likely remain undetermined due to the materials that were burning amount of overhaul of the area of origin.
