A shingle recycler whose Marengo plant exploded last week, injuring up to 15 people including himself ran into problems with regulators and residents when he tried out his idea in other states.
As firefighters responded to an explosion and fire at the C6-Zero plant in Marengo, Iowa, they didn't know the chemicals inside and the plant's sprinkler system didn't go off and appeared to not be working, according to Marengo Police Chief Ben Gray.
