E-waste is a popular name for electronic products at the end of their “useful life.” Electronics compose the largest growing segment of our nation’s waste stream. Some of these products can be reused, refurbished or recycled. If you do have e-waste, make sure to recycle it properly as these contain hazardous toxic chemicals. Computers, for example, contain lead, cadmium, mercury, chromium and polyvinyl chlorides – all of which have known detrimental effects on human health.

What Constitutes as HHW?

Many household chemicals used to paint, clean, and maintain our homes, gardens and yards can be toxic if they’re used or disposed of improperly. Household hazardous wastes (HHW) are typically categorized as flammable, corrosive, toxic or reactive. These include but are not limited to:

  • Flammable – latex and oil-based paints and stains, petroleum-based products, polishes, gasoline;
  • Corrosives – acids, bases, batteries (car and household), drain clog remover;
  • Toxics – poisons, pesticides, gardening chemicals (e.g., fertilizers), ammonia, solvents;
  • Reactive – pool chemicals, hydrogen peroxide, iodine, perchlorates;
  • Miscellaneous – propane and helium tanks, small oxygen tanks, smoke detectors, fluorescent lights, hypodermic needles, used motor oil, computers, TVs, and cell phones.

Why Recycle HHW?

Leftover HHW should never be thrown in the trash or recycling bin, flushed down the toilet, or dumped down the drain or storm sewer. A few reasons why HHW should always be properly recycled include, but are not limited to:

  • Chemicals contaminate our water supply;
  • Poured down storm drains, the chemicals end up in our creeks and the San Francisco Bay;
  • Chemicals can mix in the garbage truck and cause fires or toxic fumes;
  • Dumping hazardous wastes is illegal, and can result in fines up to $25,000.
