January 26th, 2023 – South San Francisco, CA – from SSF Scavengers Co. & Blue Line Transfer

📣The Household Hazardous Waste (HHW) Program is hosting a drop-off event in South San Francisco on Saturday, February 4, 2023, 9:00am-12:00pm. 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, aerosol cans, and automotive supplies (car batteries, motor oil, oil filters, antifreeze, brake fluid). All waste collected is reused, recycled, or stabilized for proper disposal to achieve zero waste and prevent 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.
To participate, you must schedule an appointment at San Mateo County’s HHW Program: or by calling (650) 372-6200. The event location is disclosed once your appointment is confirmed. Limit 10 gallons or 50 pounds per appointment (per car load). If you have greater than 10 gallons, you must schedule additional appointments for each 10 gallons and make separate vehicle trips for each appointment. No commercial waste allowed.
Residents unable to attend this event can still dispose of household hazardous waste for free at San Mateo County’s permanent HHW facility Thursdays-Saturdays (except major holiday weekends). You must make an appointment at 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 needed. Visit for local drop-off sites.
