Virtual Event
HILT CRC Public Webinar: Technology pathways for green iron and low-carbon steelmaking
June 24 @ 3:30 pm - 5:00 pm ACST
Virtual Event
Join HILT CRC for a public webinar showcasing four iron and steel technology providers – and HILT CRC partners – working on practical pathways to decarbonise iron and steel production.
Speakers from Primetals Technologies, Metix, Tenova and Hatch will each provide a technical deep dive into their technologies, alongside a broader view of future green iron and low-carbon steelmaking pathways.
For Primetals, Gerald Wimmer will provide a technical overview of its work supporting lower-emissions iron and steel production. The presentation will consider practical pathways for integrating new process technologies into future green iron and steel value chains, including the implications for feedstocks, energy supply, plant configuration and scale-up.
Gerhard Terblanche will present for Metix. As SMS group’s centre of competence for reduction furnace applications, Metix brings deep expertise in pyrometallurgical furnace technologies, submerged arc furnaces, high-temperature process engineering and advanced electric smelting solutions.
Tenova will provide a multi-speaker overview of its technologies across the iron and steel value chain. Markus Dorndorf will introduce the company’s direct reduced iron (DRI) and electric arc furnace (EAF) technologies; Andre Esterhuizen will discuss submerged arc furnace technology, including iBLUE® (which combines direct reduction with arc furnace-based hot metal production), residual valorisation and slag granulation; and Alessandro Della Rocca will address downstream technologies, including reheating furnaces.
For Hatch, Simon Nitschke, Managing Director, Equipment Technology, will present on Hatch’s work in green iron and steel, including the NeoSmelt electric smelting furnace (ESF) design.
Presentations from each company will include an audience Q&A after each session, with a panel discussion to close.
HILT CRC Research Director Prof. Gus Nathan (Adelaide University) will introduce speakers and moderate the Q&A and panel sessions.

Prior to that, he was a scientific researcher at Vienna University of Technology, Austria.
Gerald’s expertise spans the development, implementation and optimisation of new processes and products, customised plant revamps, and simulation-based verification and optimisation of steelmaking processes and equipment. Gerald holds a PhD in Mechanical Engineering and Simulations and a Master’s in International Business Administration.
Gerhard Terblanche, Business Development Manager, Metix (SMS Group)
Gerhard Terblanche graduated from the North-West University, South Africa, with a B. Eng (Chemical). He started his career at Xstrata Alloys (now Glencore) in 2001 as an Engineer-in-Training. Through-out his career, he has gained invaluable experience in all aspects of the smelting industry, having worked for Glencore, ASA Metals and Samancor Chrome. He has extensive knowledge and thorough understanding of ferrochrome production and related activities, ore beneficiation, wide pre-reduction and pre-oxidation process understanding, seasoned AC and DC furnace operations experience.
Professional and competent in all aspects of smelter management, Gerhard joined Metix in 2023 as the Metallurgical Product Manager and has since been appointed to lead the company’s business development department.
Dr Markus Dorndorf, Senior Business Development Director UPS, Tenova
Dr Markus Dorndorf is Senior Business Development Director UPS at Tenova, with extensive experience across iron and steelmaking, electric steelmaking, secondary metallurgy, vacuum degassing technologies and business development. Before taking up his current role in 2025, Markus served as Vice President Iron & Steelmaking at Tenova Germany, following senior roles in vacuum degassing technologies and product management/business development with Tenova and LOI Thermprocess. His earlier career included R&D leadership in electric steelmaking and secondary metallurgy at Siemens VAI, as well as research and project management roles with Helmut-Schmidt-Universität, SMS Siemag and the Fraunhofer Institute.
Markus studied Mechanical Engineering, with a focus on mechatronics and automation technology, at Technical University Bergakademie Freiberg.
