Fiberglass Recycling and Disposal - CR4 Discussion Thread

02/18/2011 2:07 AM. Fiberglass, in any form, is highly recyclable. It is used in asphalt pavement, concrete, and the manufacturing of many composites. It is not a pollutant until it is burned (a felony in the US), is cut or ground (just as asbestos), or begins to deterioate due to a poor glass/binder (epoxy resin) mix.
