That does not surprise me. At work we have to have several "waste" streams - the cost varies depending on the type. One stream is "clean dichloromethane" (- note not called waste) that comes from using dcm in a process, and then distilling it out - as it's such a low boiler (39C) then it's resonably pure - that goes off for re-use elsewhere, I doubt if we get anything for it, but the other option of putting it in the halogenated waste would be very expensive. -Ron Jones Process Safety & Development Specialist Don't repeat history, unreported chemical lab/plant near misses at http://www.crhf.org.uk Only two things are certain: The universe and human stupidity; and I'm not certain about the universe. ~ Albert Einstein
