i think so
It can be recycled just like any other type of glass. Simply heat it past its melting point, and re-cast it into something new.
Gorilla glass is scratchproof, but I don't think it is bulletproof.
Bulletproof glass
A spear is unlikely to penetrate bulletproof glass, which is designed to withstand high-velocity impacts from bullets. The thickness and material composition of bulletproof glass provide significant resistance to penetration. While a spear can deliver considerable force, it typically lacks the concentrated energy that a bullet generates upon impact. Therefore, the effectiveness of a spear against bulletproof glass would be minimal.
Glass can be recycled forever until it gets contaminated.
Yes it can. Glass can be recycled by melting it to make new glass items; but I believe it's not quite that simple.
Aluminum, and bulletproof glass.

Here's a page I found with some recycled glass prices on it. http://www.recycle.net/Glass/glass/xv090100.html
The two main sources of cullet, which is recycled glass used in glass production, are post-consumer recycled glass and pre-consumer recycled glass. Post-consumer cullet comes from glass containers recycled by consumers, while pre-consumer cullet comes from manufacturing scraps and rejects.
Alternating layers of glass and plastic resin. Truly bulletproof glass must be at least 4 to 6 inches thick! I've seen samples of such glass from WW2 bombers in museums. Modern bulletproof "glass" probably uses plexiglass plastic instead of real glass though. Note: a thick enough piece of ordinary glass is bulletproof by itself. Telescope mirrors (several feet thick) have been shot and although damaged the bullet did not pass through and after removing the bullet, drilling out the hole, and painting the inside of the hole black the telescope was returned to operation with no detectable loss of function.
