Hazardous Waste

Household hazardous waste may NOT be disposed of in the trash!

Hazardous waste, including electronic waste, accounts for significant amounts of toxic waste in landfills. Items such as electronics, fluorescent bulbs and tubes, paints, pesticides, cleaning products, old medications and other chemicals are illegal to put in the garbage or pour down a drain or gutter because they contaminate our soil, drinking water and air.

Household Hazardous Waste Drop-off Program

Cupertino residents may schedule an appointment for drop-off by calling the Santa County HHW Program at (408) 299-7300. Some examples of acceptable materials include:

      • household chemicals, such as paint and fertilizers, thermometers
      • fluorescent bulbs, electronic waste
      • propane tanks
      • medicines and sharps
      • pool and spa chemicals


    Curbside Battery Collection
    Put household batteries (e.g. rechargeable, alkaline, button) inside a tightly sealed plastic bag, and place on the ground next to your recycling cart on collection day.

    Apartment Battery Collection
    Check to see if your building has a designated area for battery collection in your building. If you don’t see one in a shared location, contact your property manager to request a collection.

    Property Managers
    Establish a centrally located collection container at your property – a lobby, multi-use room, mail room or clubhouse – for residents to place their bagged batteries. When you’re ready to schedule a collection, place them all in a sealed plastic bag and leave in the mutually determined collection location for collection.

    For safety, please tape over the contact points of each lithium battery. Look for “Lithium” or “Li” (most button and rechargeable batteries).



    When medications are disposed of in the trash or down the drain, they can end up in the wrong hands, or in our soils and waterways. Waste water treatment facilities are not properly equipped to remove medicinal substances from the water. The result? A wide range of pharmaceuticals have been found in our rivers and lakes.

    Drop Off
    Although we do not handle medications, you can drop them off for safe handling at the West Valley Patrol Station (Sheriff’s office), 1601 S. De Anza Blvd, Cupertino, and select pharmacies.



    Drop Off
    PaintCare offers take-back programs at no charge. Find a location to drop off interior and exterior paints, primers, thinners, and solvents.

    Cupertino residents may also schedule an appointment for collection at www.wmatyourdoor.com or by calling (800) 449-7587.




    Residents with medical conditions requiring the use of hypodermic needles are required to arrange for proper disposal. California law prohibits the disposal of “sharps waste” in trash or recycling containers.

    Home generated sharps waste includes: Hypodermic needles, pen needles, syringes, lancets, and other devices that are used to penetrate the skin for medical purposes.

    Drop Off & Take Back Programs
    Recology South Bay does not handle sharps. Please place home-generated sharps waste in biohazard containers (available for purchase at local pharmacies and some office supply stores) and contact your health care provider, local pharmacies, hospitals or clinics to ask if they offer a collection program.
