The fire at OmniSource in New Carlisle was put out early Wednesday morning, Aug. 25, about 12 hours after the blaze began.
Though the fire was out, crews were called back to the scrapyard to douse some hot spots, just before 11 a.m. They left about an hour later.
There were as many as 100 firefighters there as the fire burned into Tuesday evening.
Investigators think the fire started after a piece of equipment was moved.
