Firefighters battled a massive blaze Wednesday night into early Thursday at a recycling factory in northwest suburban Des Plaines.
Crews arriving just after 11 p.m. found flames coming out of the roof at 1274 Rand Rd., according to Deputy Chief Peter Dyer of the Des Plaines Fire Department.
The fire quickly spread and additional crews were called for help, Dyer said.
The blaze was under control by 2:15 a.m. Thursday, but crews remained at the scene chasing hotspots as of noon, according Des Plaines Fire Chief Alan Wax.
The cause of the fire remained under investigation Thursday, Wax said. No injuries were reported.
