Household Hazardous Waste

Santa Clara County Household Hazardous Waste Program 


The Santa Clara County Household Hazardous Waste Program (HHW) helps protect the environment and public health by collecting and properly disposing of hazardous waste from homes and small businesses. This program also provides the community with practical pollution prevention options for the use and recycling of products containing hazardous substances.

Bring your household hazardous waste to one of the free HHW drop-off events outlined in our Operating Schedule. Please note: HHW does not accept any household hazardous waste at the business office. Site addresses and directions to the facilities are only made available to residents at time-of-appointment to prevent unauthorized drop-offs and to ensure safe collection by professional staff.  
Attention Palo Alto Residents: 

Please do not make an appointment with the link above.  Contact your city's Household Hazardous Waste program for more information:

Battery Safety & Disposal

BatterySafetyBatteriesduracellimageIn California, batteries are considered hazardous waste when they are discarded because of the metals and/or other toxic or corrosive materials contained within. This includes all batteries sizes: AAA, AA, C, D, button cell, 9 Volt, and all other batteries, both rechargeable and single use. Therefore, batteries must be recycled, or taken to a household hazardous waste disposal facility or an authorized recycling facility.

Until they can be disposed of properly, caution should be taken when storing used or old household batteries. It is recommended that the exposed positive (+) terminals of the batteries be covered with electrical tape (or stored separately in ziplock bags) to inhibit the terminals from coming into contact or rubbing with other terminals or objects that can potentially cause a fire.

Where to Recycle or Safely Dispose Batteries

Santa Clara County has free household drop-off locations where residents can properly dispose of their used batteries during business hours. Residents are reminded to tape the positive (+) terminal on the batteries before dropping them off (D.O.T Regulation).
