WASHINGTON, DC, UNITED STATES, March 12, 2026 /EINPresswire.com/ -- Thermostat Recycling Corp. (TRC) announced that mercury thermostat collections continued their long-term downward trend in 2025, reflecting both the aging out of mercury-containing devices and the sustained success of national recycling efforts.

TRC recovered 438.4 pounds of mercury in 2025, according to program data, compared with 531.1 pounds in 2024. This represents a year-over-year decline of approximately 17.4%. The organization also collected 49,155 mercury-containing thermostats, down from 56,513 units the previous year for a 13% decline.

Total Pounds of Mercury Collected – 438.4 lbs. Total Thermostats Collected– 49,155.
Despite the expected decline, TRC emphasized that the program continues to play a critical role in preventing mercury from entering the waste stream.

“Our partners remain steadfast in their commitment to responsible environmental stewardship,” said Danielle Myers, Executive Director of TRC. “Even as mercury thermostats become increasingly scarce, their safe recovery and disposal remain essential. The dedication of our wholesalers, contractors, utilities, and state programs ensures that we continue to remove these devices from circulation.”
