How to Dispose of Household Hazardous Waste

Did you know it is illegal in California to simply throw some household items in the trash? Many common household items, like batteries, lightbulbs, and household cleaners, contain potentially hazardous materials or ingredients that pose a danger to the environment, and to you, if disposed of in a landfill. These items, known as Household Hazardous Waste (HHW), must be disposed of in a special way to prevent contamination of our air, water, or even food.

What is banned from the trash?

  • Lights, batteries, and electronics – this includes lightbulbs and lamps, batteries, and electronic devices like monitors, TVs, microwaves, and cell phones.
  • Mercury-Containing Items – these can include items you may not think of, like electrical switches and musical birthday cards, as well as common items like thermostats and thermometers.
  • Household and Landscape Chemicals – including flammables and poisons, pool chemicals, cleaners, and pesticides.Paints and solvents – such as latex and oil-based paints and solvents
  • Building materials – this includes treated wood and materials with asbestos, like older kinds of cement, roofing, flooring, and siding.
  • Automobile-Related – including antifreeze, batteries, motor oil, and tires.
  • Other – compressed gas cylinders, healthcare needles and sharps, paint and ballasts with polychlorinated biphenyls (PCB), and any nonempty aerosol cans labeled with “TOXIC” or “FLAMMABLE”
