STAY CONNECTED IN 2021: The Value of TMS Membership

Editor’s Note: This article corresponds with the Aluminum: Recycling and Carbon/Environmental Footprint technical topic published in the October 2020 issue of JOM: The Journal. For additional insight on this topic, browse papers in this issue or log in to your TMS member account at tms.org to read articles on Springer. Five well-known specialists in the aluminum industry were invited to participate in a JOM panel discussion and comment on the most critical challenges our industry is facing, how we might face them, and what they would have liked to know when they started their careers. Whilst we had many enjoyable and meaningful discussions, here we summarise some of the highlights from our experts.

Meet the Panelists Chris Bayliss is deputy secretary general at the International Aluminium Institute (U.K.) and has almost two decades’ experience in the sustainability of the aluminium industry. He is involved in all aspects of the Institute’s activities, from data collection and analysis to communication, and has played a leading role in collaborative projects to develop the industry’s greenhouse gas accounting protocols, occupational health performance measurement tools, the global aluminum mass flow model, and “The Aluminium Story” (www.thealuminiumstory.com). Gao Binliang is a professor at Northeastern University (China) and has been working in molten salt electrochemistry, especially in aluminum reduction, for over 20 years. His work mainly focuses on the theory of molten salts electrolysis, as well as electrochemical preparation of

Al-based alloys in high-temperature and room-temperature molten salts. He has authored more than 100 scientific and technical papers, as well as two books on molten salts. Don Doutre is senior principal scientist, molten metal processing and recycling at Novelis Inc. (Canada), and has developed the LiMCA™, AlScan™, and PoDFAf™ technologies used daily throughout the aluminium industry. He is active in the preparation, casting, and properties of metal matrix composites, as well as in automotive casting and semi-solid forming, and more recently in quality, recovery, and environmental issues relating to aluminium recycling. He has 14 U.S. patents and has been a TMS member since 1985. Stephen Lindsay is smelting specialist consultant at HATCH (USA) and previously served in technical and managerial capacities at Alcoa

for almost 40 years, with responsibilities spanning anode, cathode, reduction, and emission control technologies. He has patents related to emissions control and alumina handling and has authored dozens of articles in Light Metals, JOM, and the Australasian Smelting Technology Conferenc
