San Mateo County Facilities The recycling program for county employees Batteries Batteries are banned from landfills in California due to the toxic metals they contain. It is important that you recycle your batteries to ensure that they are disposed of properly. The best thing you can do as an individual is invest in rechargeable batteries. They cost more than disposable batteries, but the savings is realized down the road when you no longer have to purchase new batteries.

Household batteries are collected via PONY mail, as well as selected drop-off locations. All batteries are handled through the County Household Hazardous Waste Program, part of the Environmental Health Division. Lithium and Ni-cad batteries are sent to a company for disassembly and remanufacturing into new batteries. Alkaline batteries are recycled for metal.
