In King County, it is illegal for anyone to dispose of mercury-containing thermostats in the garbage or at transfer stations. This applies to residents, contractors and businesses. There are numerous free recycling options.
Most heating and cooling equipment suppliers in King County collect mercury thermostats for recycling. There is no charge for this service.
Contractors may order their own mail-away recycling bin if they have at least seven technicians or if they are located far from other recycling services.
To order a bin, contact the Thermostat Recycling Corporation or call the Local Hazardous Waste Management Program in King County at 206-263-3072. The bin is 12" x 12" x 22" and holds about 50 thermostats.
The Thermostat Recycling Corporation (TRC) charges the contractor a $25 one-time fee. All future mailing and recycling costs are paid by TRC. After the full bin is sent to TRC, an empty bin is returned to the contractor.
Recycle the entire thermostat. Don’t dismantle the thermostat or remove the mercury ampoule.
