Well as I said I first 'sweep' up and bits and pieces that didn't make into the waste bucket and then all that's left is the 'dust' and I have a long cord so I blow it out of the garage onto the lawn and then let nature do her thing and 'recycle' it back into something good!
ALWAYS make sure there are no screws or other metal objects that get blown out on the driveway. I'm the one that would have to change the tire!!!
