Probably depends on where you live but if its gross just put it in the garbage. If you are concerned about the workers safety, put it in a box and fill the box with other trash so it doesn’t present a danger. Not all glass can be recycled even if its put into the recycling bin. But even glass that is not recyclable can be used for lots of other things. One of the cool things I discovered a bunch of years ago is that junk glass that isn’t recyclable can be used to capturing methane from old landfill (they create a thick layer of crushed glass on the top of the old landfill and then cover that with a membrane and then they can suck the gas that is stuck between the glass layer and the membrane.)
