When the sharps container is full, close and seal the container and order a
new one. University waste pickup will dispose of the full container. Do not
overfill!
Broken glass:
Any broken glassware which is NOT on the sharps list can go in the
regular trash. This includes broken beakers, optics, labware, coffee mugs, etc.
Just box up the broken glass in a cardboard box, tape it shut, write “Broken
glass” on the side with a marker, and put it in regular trash can.
If the broken glass has chemical residue on it, you need to remove it using
the appropriate disposal method before you throw away the glass.
Chemical containers:
Rinse empty chemical containers 3 times, cross out the label, initial, date,
and write “Trash” on the label. Then it’s OK to put them in the regular trash.
Cardboard:
If it fits in the trash can, great.
For large boxes, break them down so they are flat, and write “Trash” in big
letters on the side using a marker. Custodians will then know which boxes to
take. If the box still contains packing material, you don’t have to break it down,
just write “Trash” on the side.
