Re: Biohazard Chemicals regulations

From:Jan Shivers <>

A brief answer to your lengthy questioning...

At the University of Minnesota, I have to package up ALL of my hazardous
waste, fill out forms, and call for hazardous waste pickup.  The U of MN
collects waste of any kind and stores it in a facility off-campus in barrels
that are then either buried or burned as fuel.  It matters NOT how dilute a
chemical may be in the collection bottle... we have to package up everything
considered hazardous by industry standards.

The only thing that goes down the drain are the non-hazardous chemicals,
such as neutral pH buffers.
