- lstodd 6y agoReused? Ha-ha. Just swept somewhere out of sight. Which is much better than the salts, because sand is mostly neutral, while salts, esp slow-dissoving stuff kills plant life long after the season ends.
- frosted-flakes 6y agoWell, it's collected, and if they already have it in a dump truck, why wouldn't they re-use it? In the spring, the street cleaner cleans my whole street, and dumps each load at the dead-end. Later, it gets loaded into a dump truck and taken somewhere (3-4 dump truck loads in total, estimated). The last few years they've used sand a lot more sparsely (only on intersections and hills), so I'm pretty sure the street cleaner only picks up one load and can carry it away without needing a dump truck.
- throwawayboise 6y agoIt's not re-used. It goes to a landfill. There's too much street garbage mixed in by the time they sweep it up in the spring.
- frosted-flakes 6y agoSounds reasonable. But even as landfill I bet it gets reused as cover.
