Re: Mixed Waste
Toluene is an F005 waste only if it is a "spent solvent." It's thus important
to find out where it originated. Toluene is often used as a reagent in
chemistry labs. If that is its origin, then it's not F005.
The opinions expressed are strictly mine.
It's not about dose, it's about trust.
