With garnet, you can recycle it on site and their some companies that will buy and recycle your abrasive to resell. That being said, garnet sand is cheap as shit and it's more expensive for most shops to recycle. I've heard that factories making backhoes and the like cutting lots of like 1/4 inch plate will because they're using just so much that it makes sense to recycle on site. All that being said, the sand will go round and be a less effective abrasive after a few uses.
