RE: Recycling used thinner



 Uniram sells a gun washer with attached still; see
http://www.uniram.com/ugi.html  
 Zep sells one that works with a closed loop still, although the combination
may not have a UL 2208 certification.

Subject: Recycling used thinner




I have a client company that is interested in recycling used thinner from a
solvent-based paint gun cleaner.  They are looking for a unit
that is closed looped, emits no VOCs, and results in clean lacquer thinner
for
re-use and solids that would be handled as hazardous waste.  A completely
closed
loop unit will exempt them from RCRA permitting issues, but the burden of
proof
will be on us.

The company currently uses the thinner to clean the pain guns and the
resulting
residue (waste
thinner and solids) is disposed of as hazardous waste.  As you know, this
will result in a benefical re-use of the thinner and reduction in haz.
waste.

Does anyone have experience with this type of unit or can recommend a unit
that
we should investigate?

Thanks for any ideas you can provide.
