Recycle Mercury Thermostats

Mercury is a heavy metal that represents a threat to human health and the environment when released into the environment. An average wall thermostat contains 4 grams of mercury, the equivalent of 800 compact fluorescent lights. Preventing toxics like mercury from entering the waste stream plays a critical role in protecting our environment and water supply.

Oklahoma City’s Public Works Stormwater Quality division operates the Household Hazardous Waste Collection Facility at 1621 S. Portland where mercury thermostats can be dropped-off for recycling during business hours. The facility is open Tuesday through Friday 9:30 a.m. — 6 p.m., and on Saturday 8:30 — 11:30 a.m. The center is free to Oklahoma City residents, but you must bring your City water bill as proof of residency.

For additional convenience, the Oklahoma Department of Environmental Quality has partnered with Covanta Tulsa and Locke Supply to provide another way to responsibly recycle mercury thermostats. Contractors and homeowners can deliver the out-of-use mercury thermostats to any Locke Supply location across the state for recycling.
