Need to get rid of an old mercury thermostat? Don't toss it in the trash! Allen's Engineering Department just launched a free disposal program. Simply take your thermostat to City Hall (305 Century Parkway) and drop it off at the front desk, located in the rotunda. Broken thermostats will not be accepted. Thermostats will not be collected through the Household Hazardous Waste pickup service.

Mercury is a heavy metal that can be a threat to human health and the environment. The average wall thermostat contains four grams of mercury, or the equivalent of 800 compact fluorescent lights.
