DE PERE, Wis. (From news reports) - Multiple fire departments helped put out an early morning fire on Nov. 23 at Sustana Fiber located in West De Pere.
According to the De Pere Fire/Rescue Department, on Nov. 23 around 4 a.m. crews responded to a reported structure fire at Sustana Fiber on W. Mathew Drive. When crews arrived they found a fire on the roof of an outbuilding.
The building and rooftop reportedly contained the equipment "to off gas a biofuel product containing methane".
The fire was quickly put out, but it did migrate into the closed-cell roof insulation. This reportedly required an extensive overhaul of the roof area.
Safety crews monitored for methane gas as well as by-products of combustion. Everything was completed around 6:30 a.m.
Officials say that damage to the building and equipment is estimated at $120,000. The cause of the fire is still under investigation.
