Household Hazardous Waste

Household hazardous waste cannot be disposed of in the trash!

Something is hazardous if it can catch fire, react, or explode when mixed with other substances, or if it is toxic. When disposed of improperly, these wastes can do serious damage to the health of humans, wildlife and the environment.

Some examples of hazardous waste are:

Ammunition Car batteries Leftover paint Medical waste

Poisons Solvents Toxic cleaners Used oil

Electronics waste cannot be disposed of in the trash!
These include computers, televisions, and cellular phones. For more information, please visit the Electronic/Universal Waste page.

Household hazardous waste and electronic / universal waste collection events are held regularly in Santa Clara County. For more information on these events, or to schedule an appointment, visit the Santa Clara County HHW Program page.
