Household Hazardous Waste

Disposing of Hazardous Materials


Hazardous materials generated by your household can be safely disposed of through the Santa Clara County Household Hazardous Waste (HHW) Collection Program. Drop-off events are held the 1st weekend of every month at the Santa Clara County facility in San Martin. There is no charge to participate, but you must call 408-299-7300 to preregister.

Common Hazardous Materials


Generally, households have 3 - 10 gallons of hazardous materials in them. Household hazardous materials include:
  • Aerosols
  • Batteries
  • Gasoline
  • Paint
  • Paint thinner
  • Pesticides
  • Pool chemicals
  • Propane
  • Strong cleaners

Sharps and Prescription Drug Disposal


Home generated sharps (disposable hypodermic needles, syringes, lancets, and other medical devices used for self-injection or blood test) and unused or expired prescription drugs and other over-the-counter medications must be properly disposed of. Get complete information.

In South County, the nearest sharps drop-off location is the San Martin Transfer Station, 408-842-3358. Download a list of other drop off sites (PDF). Sharps must be in an approved container.

Do not flush expired or unused medications down the toilet! Although this was a practice used in the past, new studies show that prescription and over-the-counter drugs are not completely removed when passing through waste water treatment plants. Harm to marine and plant life can be caused by improper disposal.

As part of the "Don't Rush to Flush" program, unwanted and unused prescription medications can be disposed of in the white collection bin in the lobby of the Morgan Hill Police Department, 16200 Vineyard Blvd. (open weekdays, 8 a.m.- 7 p.m.)

Re-Use Program

The HHW Collection Facility also offers a Re-Use Program for residents interested in obtaining free reusable products. The program is open on days of the HHW drop-off events. Residents may view collected reusable waste and may take as much as they want at no charge.
