Mike,

In my lab, I dispose of ALL dyes (H&E included) in a drum that the
hazardous waste people on campus pickup at my request.  What they do with
it after that I don't know, but I do know that the drums I fill with only
Alcohol & Histoclear is sold cheap to some factory (I was told but don't
remember which one) which uses it  for heating fuel, so at least much of my
waste is recylcled.

Also, I keep my wastes labeled and try not to mix alcohol with histoclear
as much as possible.  This is just my own thing, not any regulation of any
kind. 

Happy trials and keep smilin'
