Household Hazardous Waste Collection Program

 Who We Are and What We Do

The Household Hazardous Waste (HHW) Program, provided by San Mateo County, helps residents dispose/recycle their residential hazardous waste properly - for FREE!  County residents may drop off a full range of HHW at our Collection Facilities and Events.  All waste collected is either reused, recycled, processed for energy recovery, or stabilized for proper disposal to achieve zero waste being landfilled.

What is Household Hazardous Waste (HHW)?

HHW is a waste, from your home, that is toxic, corrosive, flammable or reactive, based on its chemical properties.  Products such as paint thinner, toilet bowl cleaner, and rat bait exhibit these hazardous characteristics.  It is illegal to dispose of such dangerous wastes in the regular trash or dump them down the drain, so use the San Mateo County's HHW Program for proper disposal.

HHW Collection Facilities and Events

Any County Resident may participate at any collection.  They are held on Thursdays through Saturdays at the main Facility in San Mateo, while events occur in Daly City, Half Moon Bay, La Honda, Menlo Park, Pacifica, Portola Valley, Redwood City and South San Francisco.

Residents must make an appointment for drop off due to participation limits at each location.  There is a limit of 10 gallons or 50 pounds per appointment based on transportation regulations.  Contact us directly if you have more than that amount.
