Broek is also a leader in SPL processing. He is up-to-date with market conditions and advices smelters such as Emirates Global Aluminium, Sohar Aluminium, and Ma’aden Aluminium on their strategies to send SPL to sustainable outlets. Broek has been associated with the aluminum industry for almost 20 years. He is a member of the TMS Aluminum Committee and a regular presenter and speaker at major international conferences such as the TMS annual meeting, Arabal, ICSOBA, and Metal Bulletin.

Margaret Hyland
Associate Director
University of Auckland-Light Metals Research Centre

Margaret Hyland is a professor in the Department of Chemical and Materials Engineering at the University of Auckland; the Deputy Dean of the Faculty of Engineering; and a principal investigator in the Light Metals Research Centre. She has a Ph.D. in chemistry from the University of Western Ontario. Hyland has been active in aluminum reduction technology, working with international aluminum producers and industry suppliers for more than 20 years. She has gained international recognition for her pioneering work in environmental aspects of aluminum reduction technology and materials performance. She is an authority on the generation and capture of fluoride and particulate emissions from aluminum smelters. She was elected a Fellow of the Institute of Chemical Engineers (UK) in 2008. She has authored more than 120 refereed publications and 100 technical reports. She and her co-authors are five-time awardees of TMS Light Metals and Carbon Awards. In 2015 Hyland became the first female recipient of the Pickering Medal by the Royal Society of New Zealand for her pioneering research to reduce fluoride emissions produced by aluminum smelters worldwide. Hyland was also the first female to chair the TMS Aluminum Committee and editor of the Light Metals proceedings in 2015.

Stephen Lindsay
Senior Smelting Specialist
Alcoa Inc.

Stephen Lindsay has served in numerous technical and managerial capacities at Alcoa over the past 36 years. He has responsibilities that range from control of fluoride emissions to raw materials including alumina, and customer satisfaction with metal purity that span Alcoa’s smelting operations worldwide. His office is based near Knoxville, Tennessee. His articles on fluoride emission control, alumina, metal purity, and other topics have been published in Light Metals, the proceedings of Australasian Smelting Technology Conferences, and the proceedings of International Alumina Quality Workshops.

David Wong
Project Manager
University of Auckland-Light Metals Research Centre

David Wong has been active in the field of aluminum reduction technology for the past decade, particularly in the field of environmental management. He led the completion of the Light Metals Research Centre’s (LMRC) Fluoride Emissions Management Guide (FEMG), its implementation in a Chinese smelter in 2010, and has also taken a lead role in the LMRC’s research of continuous PFC emissions and automatic AET termination strategies. In 2013, he completed his Ph.D. in chemical and materials engineering at the University of Auckland, focusing on particulate emissions within the potrooms of aluminum smelters. He has been an active member of TMS, co-authoring a number of papers on particulate, PFC, and fluoride emissions. In 2014, he was an instructor for the short course on Pot Ventilation & Dry Scrubbing in Aluminium Smelters and was an environmental session chair at the TMS annual meeting, and a recipient of a TMS Light Metals Division Young Leaders Professional Development Award. In addition to the environmental field, he has a strong interest in advanced process control, automatic sensors, and bath chemistry fundamentals. He has managed smelter-based projects in Australasia, North America, China, and Russia.
