Thermostat Collection Program Open to Town Transfer Stations, Recycling Centers and Municipal Offices

Many out-of-service thermostats contain up to 3 grams of mercury. Unfortunately, thermostats are frequently discarded as a solid waste where their mercury can be released to the environment. Funded by Honeywell, GE and White-Rogers, the Thermostat Recycling Corporation (TRC) provides a collection and recycling program to town transfer stations, recycling centers and municipal offices. This offers general contractors Adobe Acrobat Reader Symbol, builders and homeowners a safe, easy way to properly dispose of spent thermostats.

Since 2001, the TRC has recycled 2,879 thermostats from the state of New Hampshire which translates to 22 pounds of mercury taken out of the waste stream. As of October 2007 there are 29 active locations in New Hampshire participating in the TRC program Adobe Acrobat Reader Symbol.

NHPPP provides the first bin free of charge to participating transfer stations, suppliers and contractors with each subsequent bin costing $25. Once full, the bins are sealed and shipped to TRC where the mercury-containing ampoules are removed and sent to a mercury refiner who distills the mercury and sells it for reuse in new thermostats and switches. To ship a bin, the participant only needs to attach the provided shipping label and call for pick up. This service is entirely included in the fee for the bin.

thermostatIf you are a transfer station or recycling operator, why not call for a free bin? Even if your town does not have a transfer station or recycle center, you could place a bin in a municipal building. If you are a contractor, builder or homeowner, save your thermostats and bring them to a participating location for recycling. For any questions or to participate please contact the NHPPP at (800) 273-9469 or us at
