My thanks to Gary Hunt, Richard Illig, Sue Schauls and Deb Jacobson for their responses to Mr. Vinson’s question. We happen to be working with a NH metal fabricator that generates > 3,000 gallons of spent machine lubricant and coolant, per month. They just asked us the exact same question and the replies to Mr. Vinson’s query will be invaluable to us.
Although some people find it annoying to deal with a string of possibly irrelevant list serve responses, there are just as many, like me, who appreciate and surreptitiously use the resulting information.

It depends on the type of cutting fluid that is being used, the quantities involved and the machining requirements. There are a number of well proven ways that synthetic cutting fluids can be recycled and a lot of info available. Check out http://wrrc.p2pays.org/industry/indsectinfo.asp?INDSECT=45 . References are a little dated, but the basics have not changed. Good luck.

Greetings from Busan Korea. Jeff and I are in a meeting and we are being asked about alternatives to extend the life of cutting oil. Does anyone have an option for reuse of cutting oil, or any specific options for this company?
