I majored in glass and ceramics for my MFA, and our major melt was a recycled borosilicate glass--but not Pyrex..  Pyrex is a special blend of silica, boron oxide, aluminum oxide and more.  And now I hear the US company called Kitchen World is having it made out of a different soda/lime glass.  There are pictures on the Internet showing how it will shatter now.  Apparently it was looked into because so many drug labs were using kitchen ware and it was failing.

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.

Glass with Borosilicate cannot be recycled.

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.
