Twinsburg Township -- Firefighters from around the area responded to an industrial fire Sept. 25 just before 12:30 p.m. at Regency Technologies, 1831 Highland Road.
The Twinsburg, Hudson, Macedonia and Oakwood fire departments arrived at 12:33 p.m. to fight fires in three semi trailers, said Twinsburg Fire Department Capt. Steve Bosso.
The trailers were packed with old computers and other electronic recyclables, Bosso said.
Firefighters waited for company employees to arrive to tip the trailers on their sides, Bosso said, adding the trailers were a total loss.
"It was probably heat from a battery source that could have smoldered for days," he said. "It wasn't suspicious in any way."
Firefighters cleared the scene just before 4 p.m., Bosso said. No one was injured, he said.
The company did not return calls by press time.
