IIRC it's not usually made from recycled glass. No wonder the industry is looking out for more sustainable options, such as wheat straw that is already used by GM to reinforce plastic interior trim parts in some of their cars.

Isn't it flamable or burn easier than fiberglass ?

Flame-retardant agents are usually embedded to the resin, not to the fiber itself. Even steel sponge (bombril) burns quite easily.
