What is Household Hazardous Waste (HHW)?

According to the California Health and Safety Code, “Household hazardous waste means any hazardous waste generated incidental to owning or maintaining a place of residence. Household hazardous waste does not include any waste generated in the course of operating a business at a residence.” Some jobs around the home may require the use of products containing hazardous components. Such products may include certain paints, cleaners, stains and varnishes, car batteries, motor oil, and pesticides. The unused or leftover contents of such consumer products are known as “household hazardous waste” or HHW. Household hazardous waste includes: used oil filters, paint, antifreeze, batteries, propane tanks, pesticides, household cleaners, pool chemicals, sharps/needles, and fluorescent bulbs.

Americans generate 1.6 million tons of household hazardous waste per year. Don’t throw hazardous waste in the trash!! Municipal landfills cannot accept hazardous waste.
