Household Hazardous Waste
The Household Hazardous Waste (HHW) Program provided by San Mateo County helps residents dispose of/recycle their residential hazardous waste properly – for FREE! County residents may drop off a full range of HHW at collection facilities and events year-round every Thursday, Friday, and Saturday (except major holiday weekends).
All waste collected is either reused, recycled, processed for energy recovery, or stabilized for proper disposal to achieve zero waste being landfilled.
What is Household Hazardous Waste (HHW)?
HHW is a waste from your home, that is toxic, corrosive, flammable or reactive, based on its chemical properties. Products such as paint thinner, toilet bowl cleaner, and rat bait exhibit these hazardous characteristics. It is illegal to dispose of such dangerous wastes in the regular trash or dump them down the drain, so use San Mateo County’s HHW Program to dispose of accepted waste.
Reduce hazardous waste in the first place. Buy only what you need and look for less toxic alternatives.
