The Compressed Gas Association (CGA) presented an Environmental Recognition Award to Matheson Tri-Gas, Inc. and its parent company, Taiyo Nippon Sanso Corporation, for the development of MTG-Shieldâ„¢, an environmentally-friendly alternative to the use of sulfur hexafluoride (SF6) as a cover gas in molten magnesium production and casting.

MTG-Shieldâ„¢ is a novel integrated cover gas delivery system that can be used to directly replace sulfur hexafluoride (SF6) in molten magnesium applications. SF6 is the most potent greenhouse gas with a global warming potential (GWP) 23,900 times that of CO2. This is the highest GWP of any compound identified to date.

Rick Kowey, Executive Vice President, Matheson Tri-Gas and Yutaka Kurosawa, Senior Managing Director of Development & Engineering, Taiyo Nippon Sanso Corporation, accepted the award at the CGA annual meeting, held on March 19, in St. Petersburg, Florida.

According to Rick Kowey, $quot;Alternatives to SF6 gases have been actively studied; however, prior to MTG-Shieldâ„¢, there has not been a viable replacement with a low global warming potential that is non-corrosive and non-toxic in nature.$quot;

$quot;Environmental responsibility is one of Matheson Tri-Gas' core values, and we will continue to invest in processes to ensure adherence to this value. We will strive to make Matheson Tri-Gas an environmental leader in the industrial gases industry,$quot; continued Bill Kroll, Chairman and CEO, Matheson Tri-Gas.

The CGA Environmental Recognition Program has been established to recognize CGA Members for Environmental Excellence. A recognition award is presented annually to any facility, team, or individual in the compressed gas industry who has demonstrated environmental excellence through environmental accomplishments. The program enables the CGA to identify and share good environmental practices as well as promote environmental awareness and improvements within companies and the industry.
