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 batteries of all sizes: AAA, AA, C, D, button cell, 9 Volt, rechargeable, single use, and all others. 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.

cell phones

Cell phones contain toxic materials that threaten human health and the environment. Both batteries and cell phones are classified as Universal Waste and are banned from disposal with garbage and must be handled properly. To learn more about recycling batteries and cell phones, please visit RethinkWaste's website.

Did you know? Recology collects used household batteries and cellphones curbside. Place your recyclable materials in a sealed plastic bag on top of your blue recycle cart for collection.

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, low mercury tubes, compact fluorescents (CFLs), and 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 into 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.
