Household Hazardous Waste

Hazardous waste is any toxic chemical product you use in your kitchen, car, bathroom, garage or yard. The average home uses 40 pounds of chemicals each year and stores more than 60 hazardous products!*

*Source: RecycleWorks

We encourage you to consider non-toxic alternatives for some of the products you use, but for the rest, we ask that you dispose of them properly. For safety reasons, none of these items can be flushed down the toilet, poured into gutters or drains or thrown into the trash; in fact it's illegal to do so. They can pollute our water, endanger wildlife and pose a threat to human health.

To learn how to legally, safely and properly dispose of these items, visit the San Mateo County Health Department or call (650) 363-4718.

E-Waste

Electronic waste, also known as E-Waste, is one of the fastest growing segments of our nation's waste stream. In fact, it accounts for 70 percent of the overall toxic waste that is currently found in landfills.*

*Source: Clean Air Council

It is illegal to put Electronic waste, also known as E-Waste, in the garbage. E-Waste contains a variety of toxic components like lead, cadmium and mercury, arsenic and flame retardants, and when dumped in a landfill, these materials can potentially contaminate the soil and ground water, thus impacting surrounding areas. Electronics are made from valuable resources such as precious metals, copper, and engineered plastics, all of which require substantial amounts of energy to process and manufacture. Recycling electronics helps recover valuable materials and as a result, reduces greenhouse gas emissions and pollution, saves energy and resources by removing fewer raw materials from the planet.

Curbside Collection for Single-Family Residences

A new Door to Door curbside pick up program is available in some communities to Single Family Residents. Visit RethinkWaste for more information.

Batteries

All batteries are considered Universal Waste once discarded. They contain heavy metals such as mercury, lead, cadmium and nickel, which can contaminate the environment when batteries are improperly disposed of. This includes all sizes: AAA, AA, C, D, button cell, 9 Volt, and all others, both rechargeable and single use.

CFLs

CFLs You've probably heard about CFLs, or compact fluorescent lights, the energy-efficient compact fluorescent lamps that consumers have been encouraged to use instead of typical incandescent lights. In fact, many of you have them in your home or business. They use much less electricity; three quarters less in fact.

The Environmental Protection Agency encourages the use of CFLs to save energy and prevent greenhouse gas emissions that lead to global climate change. However, because of the mercury CFLs contain, they must be disposed of carefully. Manufacturers of fluorescent lighting products are working to reduce the amount of mercury content in CFLs, and no mercury is released when the bulbs are intact or in use, but CFLs release a mercury vapor when broken.

With about 400 million CFLs being sold every year in the United States, it's more important than ever that you don't put them in the garbage or Recycle carts. However, there are other options.

We encourage you to take them back to any of the locations noted below so they can be safely and properly disposed of. You can also look into RethinkWaste's Door to Door Program.

If a fluorescent bulb breaks in your house, the Environmental Protection Agency advises consumers to open a window, have all people and pets leave the room, (making sure no one walks through the breakage area on their way out), and stay out of the area for at least 15 minutes.

Sharps

California law prohibits the disposal of "sharps waste" in trash or recycling containers. All sharps waste must be transported to a collection center in an approved sharps container.
Sharps waste poses a threat to anyone it comes into contact with when disposed of improperly.

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

Tips on Storing Hazardous Products

  • Keep hazardous products on high shelves or in locked cabinets out of reach from children and pets at all times.
  • Never store hazardous products in food containers.
  • Keep hazardous products in separate containers - never combine them to save space.
  • NEVER mix chemicals. Mixing even small amounts of chemicals can have dangerous results.
  • Do not refill empty containers unless the label states it is acceptable to do so.
  • Never remove product labels and always leave products in their original containers.
  • Avoid storing hazardous products near sources of heat or flames
  • Purchase only what you will need and share extras with a friend of neighbor.
  • Make sure containers are clearly labeled, undamaged and sealed tightly.
  • Be aware of leaky containers, poor ventilation and the smell of fumes or chemicals.
  • Know where flammable materials are in your home and know how to extinguish them.

Collection Programs

Place home-generated sharps waste in biohazard containers. Biohazard containers are available for purchase at local pharmacies and some office supply stores. Contact your health care provider, local pharmacies, hospitals or clinics to ask if they offer a collection program.

Mail-Back Service:
Visit the California Integrated Waste Board for more information on sharps waste mail-back services in California.
