Proper Disposal Depends on Thermostat Type- Older wall-mounted thermostats may contain mercury, which is hazardous to human and environmental health. Do not put these in the garbage. Newer, programmable thermostats can be disposed as garbage.
Information listed here is for HOUSEHOLD ITEMS ONLY. Click here for business, non-profit, & agency information.

Recycle mercury thermostats for free. To determine if your thermostat contains a mercury switch, remove the front cover. Once the cover is removed you should be able to locate one or more glass ampoules (switches) that contain a silver liquid (mercury). This photograph shows the glass ampoule which contains mercury.
Take the entire mercury thermostat to the Kitsap County Household Hazardous Waste (HHW) Facility. See facility hours at the website below. Package products carefully for transportation.
