Make an appointment for the Household Hazardous Waste Collection event

Published on May 06, 2024

In partnership with the County of San Mateo Health, the City is hosting a free Household Hazardous Waste (HHW) Collection event on Saturday, May 11 from 8:30 a.m. – 12:15 p.m.

All waste collected is reused, recycled or stabilized for proper disposal to achieve zero waste. This prevents any items from going to the landfill and contaminating our water and soil. No electronic, radioactive, explosive or medical waste is accepted. This event is open to all who live in San Mateo County.

Accepted items include:

Cleaning products
Fertilizers and garden chemicals
Pesticides, herbicides and rodenticides
Solvents
Flammable liquids
Fluorescent lights (compact and tubes)
Paint thinner, acids/bases and aerosol cans
Automotive supplies (car batteries, motor oil, oil filters, antifreeze, brake fluid)

To participate, you must schedule an appointment at San Mateo County’s HHW Program or by calling (650) 372-6200. The event location will be disclosed once your appointment is confirmed. There is a limit of 10 gallons or 50 pounds per appointment (per car load). If you have greater than 10 gallons, you must schedule an appointment for each 10 gallons of waste and make separate vehicle trips for each appointment. No commercial waste is allowed.

Residents unable to attend this event can still dispose of HHW for free at San Mateo County’s HHW facility Thursdays-Saturdays. You must make an appointment online or call (650) 372-6200.

Recycling/safe disposal of paint, fluorescent lights, household batteries and used motor oil/filters can be done at a local collection center – no appointment is needed.
