Older, non-digital thermostats controlling heating and airconditioning often contain a switch with a significant volume of mercury. I don't have precise amounts, but I guess the mercury weights would be well into the 10s of milligrams, at least. Energy conservation efforts strongly advocate that people replace old stats with programmable digital units. Efforts in Canada are just now taking off in Ontario, to organize safe disposal of mercury-filled thermostats. Can anyone give me a brief overview of such efforts underway/planned for safe disposal of old stats elsewhere in Canada or in other countries? In particular, is there evidence that manufacturers are contributing cash to coordinate and organize collection and disposal efforts? Are there existing community-based social marketing resources available anywhere?

Cheers,
Neil
