With a global warming potential (GWP) of 23,900 times stronger than CO2 and a 3,200-year atmospheric lifetime, SF6 has been listed in the Kyoto Protocol as a gas to be reduced in industrial usage.  The USA, EU, China and a large number of other nations are undertaking measures to ban or strictly limit its use for the protection of Magnesium.

Our gas mixers meet the new environment regulation and comply with the UNFCCC methodology AM0065 for carbon credits certifications.

Characterization of Cover Gas and Byproduct Emissions from Secondary Magnesium Ingot Casting
In 2007, one of EPA's magnesium recycling partner companies, Garfield Alloys / MagReTech, hosted an industrial scale study of alternative magnesium melt protection technologies and their associated environmental impacts. The demonstration / measurement study evaluated three melt protection technologies; 1) MagReTech's standard SF6/SO2 based cover gas, 2) MTG-Shield™ using Novec™ 612, and 3) Dilute sulfur dioxide (SO2). EPA's analytical team also monitored for occupational exposure risks.

Characterization of Emissions and Occupational Exposure Associated with Five Melt Protection Technologies for Magnesium Die Casting
EPA, its Partner, Lunt Manufacturing, and a supporting cast of suppliers and researchers from Australia, Canada, Japan, and the U.S. demonstrated and evaluated cutting-edge, "climate-friendly" melt protection technologies that promise significant environmental benefits. Lunt Manufacturing graciously hosted the week-long trial at its Hampshire, Illinois die casting facility in August 2006. EPA’s report includes its first assessment of a "dilute sulfur dioxide (SO2)" cover gas technology.
