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.

Household 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.
