Household Hazardous Waste

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. Empty containers are not hazardous waste and can be managed safely in the garbage. Leave the lids off so waste haulers can see that the container is empty and non-hazardous.

Post Safe Waste Disposal

Cigarette Butt Litter Reduction Program

Cigarette butts that are dropped or flicked away as litter can easily be blown or washed into storm drains that lead directly into waterways without filtration. In addition to being unsightly, cigarette butts never disappear because they are made of plastic and do not biodegrade. They are toxic to marine and freshwater wildlife.

Breaking Our Bag Habit

Breaking Our Bag Habit

Important Notice: Effective Tuesday, December 22, 2020, the Health Officer Order Appendix A of the Social Distancing Protocol was revised to remove language about not permitting individuals to bring reusable items from home into stores. The removal of the language means that County residents may bring their reusable shopping bags into retail stores. Retail stores may adopt their own stricter policies prohibiting such items if they wish. For more information about the revised Order, read the County’s December 22, 2020 Health Officer Order Appendix A.

About 63 million single-use plastic bags were used every year before San Mateo County’s Reusable Bag Ordinance went into effect. Most of them ended up in landfills, or as litter on land and in our waterways.
