Household Hazardous Waste

What is Household Hazardous Waste?
Household Hazardous Waste (HHW) is a term used to identify products which no longer have a use that can catch fire or react, are toxic, corrosive, explosive, or persistent compounds.  Some examples of HHW include motor oil, drain cleaner, paint (oil and latex), poisons, pesticides, fluorescent light bulbs (tubes and compact fluorescent lights), consumer electronics (televisions, computers, cell phones, and tablets), and much more.
It is illegal in California to dispose of HHW in the garbage, pour down the drain, flush down the toilet, or pour on the ground.
