How do I dispose of a thermostat that contains mercury?
Because mercury is a toxic metal that can be emitted into the environment, drained into waterways and absorbed into the atmosphere through the process of evaporation, thermostats that contain mercury should be recycled rather than thrown in the trash. Many retail stores as well as heating, plumbing and electrical wholesalers accept mercury thermostats for recycling. Bring your old mercury thermostat to a participating wholesaler for a $5 mail-in coupon or take your thermostat to a participating retailer for an instant $5.00 credit. For other helpful information, please visit the DEP's web site that describes the elements of Maine's Thermostat Recycling Program and for a map-based guide to find recycling locations for electronics, fluorescent lamps and mercury thermostats visit Help ME Recycle
