Demystify: 

The recent threads on disposal of trace quantities of hazardous
materials prompts me to ask about how to properly dispose of used
autosampler vials, typically containing ~1mL each of dilute solutes in
some solvent such as acetonitrile. Also, how should broken glassware be
dealt with? In my experience these items have been disposed of in the
trash, but I suspect that may not be best practice.

If these items require treatment before disposal that's going to cause
quite a bit of push-back from staff.
