Mercury Thermostat Recycling Program

Recycle IconThe thermostat recycling program has been expanded! Certain HVAC contractors and household hazardous waste collection programs are now eligible to obtain their own recycling containers.  



The Colorado Department of Public Health and Environment strongly encourages heating, ventilation and air conditioning (HVAC) wholesalers, distributors, installation contractors and household hazardous waste collection programs to participate in the Thermostat Recycling Corporation's thermostat recycling program for all brands of wall-mounted mercury thermostats removed from service. The program is designed to provide a convenient and inexpensive way for you to recycle mercury thermostats. Participating facilities are encouraged to accept mercury thermostats from homeowners and other entities that wish to recycle mercury thermostats.


The Thermostat Recycling Corporation (TRC) was established by Honeywell, White-Rodgers and General Electric to recycle mercury-containing thermostats. It is a reverse distribution system where thermostats are collected after they have been removed from service and are put into the special collection containers located at participating facilities for recycling. When the collection container is full, the participating facility returns the container to the Thermostat Recycling Corporation in exchange for a new container. The mercury switches are removed from the returned thermostats and sent to a company that purifies the mercury for reuse. After a nominal fee for the initial collection container, the Thermostat Recycling Corporation pays all costs for shipping and recycling of the collected mercury thermostats.


This program is designed for wall-mounted mercury thermostats only and does not include other mercury-containing devices like batteries or fluorescent lamps. It is important that the entire thermostat be returned since the thermostat housing provides protection for the mercury switch during shipment. Thermostats returned under warranty should not be included in the recycling containers.
