We replaced our old thermostat with a new, more efficient digital one. There is mercury in the old one and I want to be sure we dispose of it properly. Anyone know what to do?

  1. Any decent metal recycling center should take it if it looks silvery and not red. It’s about worth about $600 per standard flask. They won’t pay you anything for the amount in a few thermometers, but at least it will go to good use rather than polluting the environment.

    You can also bring up to two thermometers at a time to one of the city’s special waste collection depots:

    Dumping these in the trash is, as you know, a bad thing. Despite the sophisticated containment in modern dumps, Mercury is difficult to contain because of the very physical properties which make it so valuable. Also, these old thermometers contain a LOT more mercury your batteries and CFLs.

  2. I just read something about this… you have to bring it to a city landfill or drop-off place – the same place you take paint. I’m sure googling or going to the city/sanitation web site will tell you.

  3. I think many old thermostats actually pre-date 800 numbers. The Honeywell thermostat I replaced a couple of years ago certainly didn’t have any phone number on it. I think this isa very good question.
