Thermostat Recycling

In California, it is illegal to dispose of thermostats containing mercury in the trash. Mercury is a heavy metal that may cause serious health problems to humans and threatens marine wildlife.

Batteries can be defective, damaged, or recalled and must be handled properly. To learn how to safely dispose of batteries and find additional battery locations in the County, visit Call2Recycle.
