SURE they can be recycled. Grind em up and use the dust in the molding process to make the same thing. We routinely used fiberglass dust to stiffen resin for filler applications, repairing Kenworth hoods for example.

BTW, those bird choppers near Benicia that I mentioned? After a few years they proved economically unviable, the company went out of business, and the bird choppers crumbled into ruin until, several years later, someone (probably some government agency) cleared the site. If you drove through that area along I-680 since the mid-late 80s, you wouldn't have seen those bird choppers or their ruins.
