Invitation to Participate for Colorado Household Hazardous Waste Collection Programs

The thermostat recycling program is a reverse distribution system where out-of-service thermostats are collected from both household and commercial consumers. The thermostats are placed in special thermostat collection containers at participating facilities. When the collection container is full, the participating facility returns the container to the Thermostat Recycling Corporation in exchange for a new container. The Thermostat Recycling Corporation arranges for recycling of the mercury from the thermostats. See how easy it is to participate in this program by reviewing the information and guidelines for participating facilities. See also a list of questions and answers for collection facilities interested in participating in this program.


Hundreds of mercury-containing thermostats are replaced each year in both commercial and residential buildings. If a convenient and environmentally sound way to recycle the mercury is not provided, many of these thermostats are disposed of in the trash. Once sent to a landfill, mercury may leak out of the thermostats and potentially get into the air and water, thereby contaminating ground water, surface water and drinking water resources. Mercury contamination can affect our air, water and soil. Mercury accumulates through the food chain and can be ingested by humans through consumption of fish caught in contaminated lakes and rivers.


Mercury has been shown to have long-lasting health effects and human exposure to mercury has been linked to nervous system, kidney and liver damage, impaired childhood development and may cause cancer.


For the recycling program to be successful, we need your active support and cooperation. Your role in this program is to obtain one or more collection containers and place them at your location so that out-of-service wall-mounted thermostats can be collected. In order to recover a higher percentage of mercury thermostats, you are asked to actively encourage participation in these recycling efforts. You are also encouraged to accept intact mercury thermostats from any entity that wants to participate in this valuable program. This collection program is designed to be consistent with the Universal Waste Program for non-residential generators of mercury thermostats.


There is an initial cost of $25 per collection container, but all other costs of shipment and recycling are borne by the Thermostat Recycling Corporation. To obtain one or more collection containers, please complete the order form and return it to the Thermostat Recycling Corporation for processing.

There is no cost to consumers to participate in the program if they take their thermostats to a participating facility that has a collection container.


Originally, only Heating, Ventilating, and Air Conditioning (HVAC) wholesalers and distributors could have collection containers. Heating, Ventilating, and Air Conditioning (HVAC) contractors and service technicians were directed to take their thermostats to these central collection points when they picked up new supplies. The recycling program has since been expanded to allow certain Heating, Ventilating, and Air Conditioning (HVAC) contractors that often don't visit their wholesaler location on a regular basis to obtain their own collection containers. Household hazardous waste collection programs are also now allowed to have collection containers.
