Safe and proper disposal of household hazardous waste
Household Hazardous Waste (HHW) doesn’t belong in any of your collection carts. Placing any HHW in your carts is illegal and unsafe for our workers, our community, and the environment. Not sure if something is hazardous? If the item is flammable, toxic, explosive, poisonous, or contains mercury or heavy metals, it’s hazardous.
The table below lists common hazardous items and indicates if we can collect them curbside on your regular service day or if they can be delivered to Blue Line Transfer. Don’t see a particular item? Try searching for it in our Sort Smart Recycling Guide. Please click here for detailed information about used motor oil & filter recycling.
Have something that we don’t collect and won’t accept at Blue Line? Visit the San Mateo County Household Hazardous Waste website. Be sure to review the “What Goes Where” charts and to make an appointment for a free drop-off.
