Various types of wastes are generated in laboratories. The most common wastes and how to dispose of them are described below:
- Empty chemical containers
- Make sure that the container is empty
- Check if the chemical is p-listed. If chemical is p-listed, rinse container 3 times, collecting ALL rinsate in your hazardous waste container.
- If chemical emits strong odors, rinse container twice and collect rinsate in your hazardous waste container.
- Remove label or simply deface by crossing out label completely (label should be unreadable) using a marking pen
- Dispose as regular trash. If container is glass and NOT BROKEN, place in sturdy cardboard box. Tape the box closed, label with “EMPTY GLASS BOTTLES” and place in dumpster.
- “Clean” broken glass (not contaminated with biological or radioactive materials or
- Place in a small or medium-sized thick cardboard box lined with heavy duty trash bag. A thick cardboard and thick plastic lining are necessary to catch any excess liquid and small glass pieces and to keep sharp edges from poking through the box. A large box full of broken glass us usually very heavy for lifting.
- Once the box is full, tape the box securely. Label with “Clean Broken Glass”.
- Place box in the dumpster.
- Used oil
- Collect in plastic waste container, label as “USED OIL” and schedule for pick up with hazardous waste.
- Hazardous (chemical) waste
- Biohazard waste
- Radioactive waste
- Mixed waste
- Mixed wastes are materials contaminated with two or more of chemical, biological or radioactive agents. Avoid generating mixed wastes as much as possible. Call EH&S 803-777-5269 to determine the best way to dispose of mixed wastes.
