Illegal in Garbage & Drains
Contains Mercury
Hazardous Waste

Take any item containing mercury directly to the Household Hazardous Waste drop-off facility. Place in clear, labeled plastic bag before transporting. Typical items are thermometers, thermostats, dental amalgam and fillings, barometers, manometers, old chemistry sets, and blood pressure measuring devices.


How to Check for Mercury

A silver, metallic liquid will be visible from inside the bulb or vial if the thermometer contains mercury.

Digital Thermometers Are E-Waste

Remove batteries and dispose of them as household hazardous waste. Next recycle digital thermometers as e-waste, because they contain small electronic parts.

Put Everything Else in Trash

If you have a thermometer that is not digital and does not contain mercury, it’s safe to throw away.

Ways to Reduce


Don't Purchase Mercury

If you avoid purchasing mercury, you can reduce the amount that is available to leach into lakes and rivers.
