That leftover 1-2 mL in GC or HPLC vials will be hazardous waste. At the very least, they will be D001, and likely listed as well depending on the solvents in question. When I generated those vials myself, especially in the analytical service
lab I worked in, I could have hundreds each day. Add in another 20 chemists and that starts to be a decent volume.
Here, we have labs collect the vials in another container (sturdy Ziploc bag, empty 4-L, etc.). We have an established profile with our waste vendor for these, coded for common solvents. Our technicians collect them like any other hazardous
waste, transport them to our waste facility, and commingle them with other like-wastes in an open top drum. We extend this to hazardous wastes in centrifuge tubes, scintillation vials, and other small containers. This works reasonably well, is easier for the
researchers than emptying out hundreds of vials, and it keeps us compliant.
Hope this helps. If you are new to the exciting world of RCRA, I would suggest looking into a training course. The Haz Waste forum is also a wealth of information for the hazardous materials management side of things.

Subject: [DCHAS-L] GC/MS vial disposal?
I have been CHO for about a year, so still pretty new.
One of the questions that has come up is What is the best practice for disposing of GC/MS vials after they have been used. I was thinking you would uncap them add the excess sample to a hazardous waste bottle. But the faculty members tell
me they don't have to remove that leftover 1-2ml of sample and solvent and they just put the vials into broken glass even if they are still half full with solvent.
