[GreenYes] RE: EPA mercury model


Hi Matt ~

Yes, the EPA numbers do include all fluorescents. The model does show a break down of fluorescents and non-fluorescents (some of which also contain mercury).

BTW, some CFLs have more mercury in them than the linear bulbs. All should be recycled.

Again, I would be glad to send the model to anyone. There are a lot of mercury products that should be diverted from landfills and incinerators and I would encourage all recycling programs to help out in this effort.

John -

I'm way out of my league here, but wouldn't the EPA number (for mercury) include all fluorescent lights (like the long white tube kind, that are fairly ubiquitous) versus the smaller, individual fixture Compact Fluorescent Lights (CFLs) which are not quite as mainstream, but are seen as one quick thing an individual can do to reduce individual energy consumption?

Does EPA break out the source of the Hg (i.e., type of light, etc)?

According to the mercury flow model done for EPA, the release of mercury from fluorescents to the environment in 2005 in the US is estimated at about 8.2 metric tons, down from 13.7 metric tons in 2000.

All the coal burning power plants in the US emit about 45 metric tons of mercury to the air.

So, fluorescents are not an insignificant source of mercury emissions to the environment.

Please let me know if you would like a copy of the model, which is an Excel spreadsheet.

The ENERGY STAR program has pretty rigorous QA/QC in terms of lumen maintenance and hours of use. If they don't perform, they don't get certified. IF they don't get certified, Wal-Mart won't sell them. Also, the EPACT set up certain hours of use requirmenets for CFL's - I think it is 6000.

Don't forget, as a source of anthropogenic Hg, this is a very small one.
