How to Recycle Batteries, Cell Phones, and Fluorescent Lamps:

All batteries, cell phones, and fluorescent lamps and tubes in California must be either recycled, taken to a household hazardous waste disposal facility, or taken to a universal waste handler (e.g., storage facility, broker) or an authorized recycling facility. Batteries: All batteries are considered hazardous waste in California when they are discarded. This includes all batteries of sizes AAA, AA, C, D, button cell, 9 Volt, and all other batteries, both rechargeable and single use. Batteries are considered hazardous because of the metals and/or other toxic or corrosive materials contained within. Batteries are potentially a valuable source of recyclable metal. Alkaline batteries, unless labeled low mercury, typically contain 1% mercury content. Although this amount seems small, due to the volume of batteries purchased and used, it can have serious impacts on the environment. Some estimates suggest that 88% of all mercury in the municipal solid waste stream is from ordinary non-rechargeable dry cell batteries such as the ordinary AAA, AA, C, D, button cell, and 9 Volt batteries.

How to Recycle Fluorescent Lamps:

All fluorescent lamps and tubes are considered hazardous waste in California when they are discarded because they contain mercury. This includes: Fluorescent tubes, including low mercury tubes. Compact fluorescents (CFLs), including low mercury lamps. When mercury-containing lamps or tubes are placed in the trash and collected for disposal, the lamps or tubes are broken and mercury is released to the environment. Mercury vapors from broken lamps or tubes can be absorbed through the lungs into the bloodstream. People who are particularly close to the breakage are especially at risk. Mercury from broken lamps and tubes can also be washed by rainwater into waterways. All fluorescent lamps and tubes should be recycled.

Please click here for a list of locations that accept fluorescent tubes and bulbs and safety tips for broken lights.

Did you know? Foster City residents can bring up to 6 fluorescent lights per household for proper disposal to the city's annual e-waste events. Go to the city's homepage to view the calendar of events for this year.
