Borosilicate glass can't be recycled with regular glass because its a contaminant - it will alter the melting point, viscosity, etc. and physical properties of the final glass.

But it CAN be recycled.  A quick Googling gives:

Not sure it's worth the risk/cost/benefit to bother, though.  You're talking about stuff that can sever arteries after all,  you need to segregate your types of  glass, the stuff has to be free of residues, the volume of the waste stream is pretty low etc..   For the most part, the logistics and practicalities make it better and easier to simply throw it in a landfill-bound box.  Presumably one could expend the same amount of time and planning on some other endeavor that has a much bigger green impact.

Does anyone know of a recycler of Pyrex glass, preferably in the Midwest?  Our normal recycler does not take Pyrex glassware and no-one else seems to that I can find.  I'm referring to clean, but may be broken, high temp glassware; so there is no concern with chemical contaminants.
 
Appreciate any assistance with this.
