Tests Show Promise for New Environment Friendly Technologies In The Magnesium Industry

Emissions of the most potent greenhouse gas, sulfur hexafluoride (SF6), could
be history in less than four years, according to results of pilot tests
conducted by the US American Environmental Protection Agency (EPA) and the
magnesium industry. Preliminary results show that alternative technologies have
the potential to replace SF6, which is used to prevent oxidation and burning of
molten metal, agency officials announced last week.

"By investing in innovative technologies, our country's environmental well
being will improve," said Bill Wehrum, EPA acting assistant administrator for
Air and Radiation.

Led by EPA's SF6 Emission Reduction Partnership for the Magnesium Industry, a
group of companies and researchers from Australia, Canada, Japan, and the U.S.
conducted the tests and emission measurements for cutting-edge, climate
friendly melt protection technologies that promise significant environmental
benefits.

EPA's Magnesium Partnership is a cooperative effort between EPA and industry to
reduce and eliminate emissions of sulfur hexafluoride from magnesium production
and casting processes through cost-effective technologies and practices.
Eliminating emissions from SF6 about three million metric tons of carbon
dioxide equivalent annually is roughly equal to emissions from 500,000 vehicles
per year.
