Household Hazardous Waste
What is Household Hazardous Waste (HHW)?
HHW is waste from your home that is toxic, corrosive, flammable, or reactive based on its chemical properties. Products such as batteries, paint and paint thinner, pesticides and fertilizers, and poisons are considered hazardous waste.
It’s illegal and unsafe to dump this waste in the trash or down the drain. San Mateo County’s HHW Program helps residents reuse, recycle, or responsibly manage residential hazardous waste for free. Learn about the multiple easy and free ways to safely and properly remove HHW from your home here.
If you have questions, contact us at hhw@smcgov.org or (650) 372-6200.

MOVING? THINGS TO KNOW BEFORE YOU GO!
HHW can only legally be transported by the person or persons who generated that waste. If you’re moving out make sure to properly dispose of your HHW, and if you’re moving in—confirm that you’re not stuck with the leftovers. Products such as batteries, paint and paint thinner, pesticides and fertilizers, and poisons are just some examples of hazardous waste — and probably won’t make the move.
Moving creates a long list of to-do’s whether you’re buying or selling a home. Here’s a checklist to help you stay organized.
Where to Recycle Fluorescent Lights
Fluorescent lights save electricity and are a good choice for energy conservation. However, all fluorescent lights contain a very small amount of mercury sealed within the glass tubing. This means the lights are toxic and can’t be put in the trash.
