Hazardous 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.
Residential: Although Recology San Mateo County does not handle hazardous waste, you can learn more about safe disposal with San Mateo County Health. For a list of acceptable items from the County program click here.

Apartment Battery & Cell Phone Collection Bucket
Check to see if your building/complex has a designated area for battery and cell phone collection. If you don’t see one in a central location, contact your Property Manager who can request a free Recology Collection Bucket.
Establish a centrally located collection container at your property – a lobby, multi-use room, mailroom, or clubhouse – for residents to place their bagged batteries and cell phones, in a collection bucket provided at no charge by Recology San Mateo County. When you’re ready to schedule a collection, place the bucket in the mutually agreed upon collection area and call Recology San Mateo County to schedule your free pickup.
Many local retailers also accept old batteries and cell phones for proper disposal. Please visit www.RecycleStuff.org for drop-off locations. You may also drop off batteries and cell phones, along with other electronics, at the Shoreway Environmental Center at 333 Shoreway Road in San Carlos.

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. Wastewater 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.
San Mateo County has many pharmacies (including all CVS locations) and local police departments that provide convenient take-back of unwanted medicines at no charge. Residents should call ahead to confirm hours of operation for locations.

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 include: hypodermic needles, pen needles, syringes, lancets, and other devices that are used to penetrate the skin for medical purposes.
Contact your health care provider, local pharmacies, hospitals, or clinics to ask if they offer a collection program. Bio-hazard containers used to contain sharps waste are available for purchase at local pharmacies and some office supply stores. Visit San Mateo County Health Department or Flows to Bay for more information on sharps drop-off locations.
