Household hazardous waste
In partnership with the San Mateo County Health, the City of Menlo Park hosts periodic household hazardous waste (HHW) drop-off events. The next event is Saturday, Oct. 21 from 8:30 a.m.–12:15 p.m. This event is open to all who live in San Mateo County.
 
Accepted items include cleaning products; fertilizers and garden chemicals; pesticides and rodenticides; solvents; flammable liquids; fluorescent lights; paint thinner; acids/bases; aerosol cans; automotive supplies (car batteries, motor oil and filters, antifreeze, brake fluid), among other chemicals. No electronic, radioactive, explosive, medical or commercial waste is accepted.
 
To participate, you must schedule an appointment at San Mateo County’s HHW Program or call (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.
