Large volume users do recycle the abrasive - Not practical for
smaller users like me - If you cut steel and use it for concrete the
result would soon be rust-colored after being rained on for a short
time - Makes a pretty good yard pot-hole filler but you could run
afoul of the environmental folks - I recently read of a case of a
company being charged with "heavy metal" pollution but they were only
cutting aluminum - Who knows how the folks at Uncle Sam make their
decisions? - Seriously though, a lot of metals have components that
would officially be considered dangerous pollutants if the abrasive
were just discarded after use - One of my sons is a Chemistry
Professor and Uncle Sam insists that Sodium Chloride in his lab be in
special double walled protective containers so that pollution doesn't
occur in case of a spill - I kid you not -

Regarding details on a home-built unit I'm doodling on - Not far
enough along to release anything as I mentioned before - Probably be
a couple of years until ready - So many projects, so little time -
Anybody who wants to contact me about it should do so on my e-mail
address as this is probably drifting Off Topic quite a bit -
