San Mateo County’s HHW Program helps residents reuse, recycle, or responsibly manage residential hazardous waste for free. There are multiple easy and free ways to safely and properly remove HHW from your home. County residents can:

1. Local Drop-off locations: Find convenient, local recycling and disposal options for paint, electronics, batteries, fluorescent lights, medicines, 1 lb. propane cylinders, and more. 
2. Curbside Pick up: Take advantage of battery and used oil pick-up on your recycle/garbage collection day. Check your hauler for details.
3. Make an HHW drop-off appointment online, or call 650-372-6200. Review the program rules and schedule an appointment that’s convenient for you.
