How to dispose of batteries at UC San Diego
How you dispose of batteries at UCSD depends on where your facility is located, whether you have a Waste Generator Number (WGN) or not, and the size and type of battery. Follow procedures for:
- Hazardous Waste Generators that have a WGN, such as research labs and shops
- Campus and SIO facilities that don't have a WGN
- Medical Center (Hillcrest) and Thornton Hospital
Note: Students who live on campus can bring their used batteries to these locations for proper disposal.
