It took nearly all night, but firefighters extinguished a fire that tore through an asphalt shingle recycling plant at Marengo in east-central Iowa.
Firefighters worked until 4 a.m. Friday to extinguish the fire, Marengo Police Chief Ben Gray said. The fire broke out following an explosion at the C6-Zero plant shortly after 11 a.m. Thursday. C6-Zero recycles used asphalt shingles into biofuel.
