Is this the case in reality? Everywhere I've lived drinking glasses were not accepted as part of domestic glass recycling due to their composition [0]
Perhaps there is a commercial recycling route for pubs though? A quick google didn't turn anything up.

All the places I know (Denmark/Germany) the glass you want to recycles is getting dumped in containers where it breaks most of the time when you toss it in.
The recycling containers here have separate containers for clear glass and coloured glass and I've always thought glass is glass.
Now I checked in detail what is accepted, and sure enough, drinking glasses and mirrors are specifically disallowed.
From a glass making point of view you don't want them messing with expansion coefficients and bulk properties so they're off the table there - it's a waste of energy to reheat them up to ~ 1,000 C.
But you do end up with large volumes of glass .. a relatively consistant material, you might want to crush and tumble that (to take the sharp edges away) and use that sized grit | frit as driveway material, as additive to concrete where structurally sound, as fish tank "sand", etc.
The tumbling was only meant to be applied to application requiring rounded grit, you're correct that concrete and other uses might prefer jagged.
Hmm, practical concerns about acquisition aside, would lunar dust work?
