Jake, unless you can manage to incorporate the separation procedure into a lab exercise this may be construed as treatment of waste requiring least that was the position of the NYS Department of Environmental Conservation and I believe the EPA, but you may want to check with other experts in this area (I've been away from this activity for a few years). Hope it's helpful.

Our university just recently became a large quantity waste generator. We have been trying to find ways to reduce/reuse/recycle. One of our largest wastes is from the organic chemists. The waste in question is hexane/ethyl acetate. Has anyone heard of a way to separate these two and reuse them?


Thank you,
