No one was injured at the company, which makes kitty litter. The fire was contained in a silo at the plant, and explosion-proof doors prevented the flames from traveling farther.
Seven Scotland County Fire Department fire engines, three tankers and an air truck and rescue responded to the scene around 8:40 a.m.
The fire was under control by 1 p.m. but rekindled around 1:45 p.m. Firefighters returned to put it out again. No other information was released.
