We had a lab distilling ethanol and xylene. Some researchers were willing to use the recycled materials, but more were deeply skeptical. Some were willing to use the ethanol for disinfection. I agree with Brandon,
check to make sure that people will be willing to use it.

Jake,
I am going to play devil’s advocate here and would love to hear some of the other responses to this, but have you broached these thoughts with your researchers? The waste stream you mentioned
is primarily from column chromatography, where large volumes of solvent are used to purify and isolate compounds. These same combinations ae used in thin layer chromatography to identify compounds as they come off of the column. I have broached the topic
of distilling and reusing ethyl acetate and hexanes at two different research institutions. In both cases the researchers were steadfast that they would not use reclaimed EtOAc or hexanes in their research due to purity concerns.
If you chose to pursue this, it would have to have buy in from the researchers and you most likely would have to have analytical testing demonstrating its purity before a researcher would ever
consider using it.
On the other hand, if your undergraduate labs are also large consumers, you could potentially take the large volumes collected from the researchers and reuse as much as you can in the undergraduate
labs where they are learning the techniques for TLC and column chromatography, but not as concerned about product purity.
For the rest of the listserv: Have any other research institutions had any luck in getting their researchers to buy into reusing solvents processed in house?

Carlos,
That is a good point. We are new to this status and we are slowly figuring out the complexities. I think we need to get a permit just to be on the safe side. Thank you for your response.
Best regards,

Jake, unless you can manage to incorporate the separation procedure into a lab exercise this may be construed as treatment of waste requiring permitting...at 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.

Greetings,
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,
