San Mateo County residents can make an appointment to dispose of household hazardous waste (HHW) for free at a special collection event in Foster City on Saturday, August 25, 2018, from 8:30 AM to 12:15 PM.
Accepted items include cleaning products, fertilizers, pesticides, flammable liquids, fluorescent lights (compact and tubes), paint, acids/bases, aerosol cans, automotive supplies (car batteries, motor oil, oil filters, antifreeze, brake fluid), inks, and photo chemicals. 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 water and soil. No radioactive, explosive, or medical waste is accepted.
