Marc is a chemical engineer, specialising in greenhouse gas (GHG) and energy management, sustainability and renewable energy, with 20 years experience in both operational and consulting roles across a wide range of industries including mining, mineral processing, oil and gas and chemicals/heavy industry. Marc is Singapore based and through his company, engeco, helps businesses understand the risks and opportunities associated with climate change. Prior to founding engeco, Marc spent many years working in greenhouse gas and energy management as the GHG technical manager for a multinational oil company, and for Australia's largest specialist energy and greenhouse gas advisory consultancy. He is a committee member of the Singapore International Chamber of Commerce Circular Economy Committee and speaks regularly on circular economy and its intersection with climate change mitigation and adaptation.

Dr Carlito Baltazar Tabelin is an environmental geochemist highly competent in the fields of inorganic contaminant geochemistry, rock-soil-water interactions, geochemical and reactive transport modelling and electrochemistry. He earned his PhD in Field Engineering for Environment from Hokkaido University in 2011 and worked in Japan as an academic staff until January 2019. He joined the School of Minerals and Energy Resources Engineering at UNSW Sydney in February 2019 as a lecturer. His current research projects include finding ways to add value to mine wastes for their sustainable management, AMD/ARD prevention and control, remediation of contaminated sites, and recovery of valuable metals from mining, industrial and electronic wastes.

Dr. Ilhwan Park is currently working as an assistant professor in the Division of Sustainable Resources Engineering, Hokkaido University, Japan. He earned his Ph.D. in the field of Sustainable Resources Engineering from Hokkaido University in March 2019. His research interests include mineral processing, extractive metallurgy, resources recycling, and environmental geochemistry. He is currently doing several projects on mineral processing, such as flotation of sulfide ores, and environmental remediation like acid mine drainage prevention.

The main research interests are related to Fine particle flotation : experimental study and modelling of the synergistic effects in mixed collectors systems and Reverse cationic flotation of iron and phosphate ores with complex gangue. Hi is author of more than 190 published journal and conference papers and more than 20 patents

Dr Richard Alorro is a research and teaching academic with more than 10 years of experience in the fields of Metallurgical Engineering, and Resources and Geo-Environmental Engineering. He is currently a Senior Lecturer of Metallurgical Engineering at the Western Australian School of Mines: Minerals, Energy and Chemical Engineering, Curtin University. He coordinates and delivers core Metallurgical Engineering units both in undergraduate and postgraduate levels. His research areas include leaching and separation technologies, technospheric and urban mining and resources reprocessing, processing of technology metals (rare earth elements and rare metals), waste treatment and environmental remediation. Richard completed both his Master of Engineering and PhD degrees in Resources and Geo-Environmental Engineering from Hokkaido University (Japan) with a scholarship grant from Japan's Ministry of Education, Science and Technology (MEXT). From his work, he has published papers in leading international journals, attended and presented in several international conferences, granted a patent, and received a Young Author Award from the International Mineral Processing Congress (IMPC) in 2010. Prior to joining Curtin University in 2013, he served as a Corporate Metallurgist at the Department of Metals and Mineral Resources of Toyota Tsusho Corporation (Nagoya, Japan), the trading house of the Toyota Group. While in Toyota, he was involved in the development of refining processes and management of related technologies required for rare earths and rare metal mining and processing.

Seher Ata is Associate Professor in the School of Minerals and Energy at UNSW. Prior to joining UNSW, she was a Research Academic at the Centre for Multiphase Processes, the Newcastle University. Dr Ata’s research interests focus in fundamental and applied research into froth flotation, a separation technique widely used for treating of fine-size ores. She has worked on a wide range of projects which have concentrated on bubble-particle interaction, froth phase behaviour in industrial flotation cells and the impact of water chemistry on the efficiency of coal processing plants.
