The substance that caught fire last Friday is essentially the material that coats automotive glass and prevents it from shattering.
Called polyvinyl butyral, the material is essentially stripped away from automotive glass recycled at the plant and stored in a large pile at Dlubak Glass, located at 1052 Industry Drive.
The material is “not known to contain toxic chemicals,” according to a material safety data sheet released by one of the product’s manufacturers, Dupont, in 2010.
It does, however, release a number of chemicals when burned.
