Household Hazardous Waste Disposal

Drop off is by appointment only and appointments can be made here: https://www.smchealth.org/post/make-hhw-drop-appointment#Appointment

The Household Hazardous Waste (HHW) Program provided by San Mateo County helps residents properly dispose and recycle their residential hazardous waste for FREE! Residents must make an appointment and limit waste to 10 gallons or 50 pounds. Event location and directions will be provided after making an appointment. For more information, such as acceptable waste types, or to schedule an appointment, call (650) 363-4718 (select option 3) or visit their website.

San Mateo County residents may also drop off HHW year-round at the main facility in San Mateo or at other collection events. For further details or to make an appointment, please visit https://www.smchealth.org/hhw.
