AIST Decarbonization Subcommittee Webinar #9 –The Green Steel Revolution
4 February 2025 • Zoom • 4–5 p.m. EDT
About the Program
Sara Hornby was awarded this prestigious annual bursary which involves touring globally for 12 months to present to students and young professionals iterations of her work: The Green Steel Revolution. In this webinar, Hornby takes a look at key aspects of the many pathways laid out in recent times by the industry and challenges some of the earlier assumptions made, planned versus actual progress, as well as analyzing the technical, logistical and social challenges that remain. Summarizing with suggested actions and solutions, this webinar is a must for all AIST members involved in or interested in the successful “Greening of our industry.” An extended question-and-answer segment will provide many learnings for all participants.

Her expertise includes scrap optimization, focusing on cost reduction through efficient scrap management. She has worked extensively with electric arc furnace operations, focusing on process optimization, including burner profiles to improve thermal efficiency and reduce operational costs. Araujo is experienced in secondary refining processes, ensuring steel chemistry consistency for high-quality steel production. Her experience extends to blast furnace operations, where she has worked with both charcoal- and coke-based ironmaking processes, optimizing reducing agent ratios for maximum efficiency. Her career reflects a commitment to improving operational efficiency and advancing the steel industry’s transition toward a more sustainable future. She is passionate about applying innovative solutions that bridge industry best practices and emerging technologies.
Presentation: The Green Steel Revolution, Sarah Hornby, Owner, Global Strategic Solutions Inc.
Presenter Bio: Sara Hornby, variously described as a trailblazer and an inspiration for ambitious women, has continually proven nothing is out of reach for women in engineering. The first woman to graduate from Sheffield Hallam University (SHU) with a BScHons in metallurgy, she spent her early career in the U.K. working for Firth Brown Tools Engineering and British Steel Corp. Her initial Canadian and U.S. Air Liquide roles, developing new technologies and bringing best available technologies to the metals industry (whilst managing multidisciplinary, multilocation team members), coupled with other electric arc furnace steelmaking optimization positions (Tenova Goodfellow, Midrex, Linde, Intertech and TMS International), put her in good stead to set up her own company, Global Strategic Solutions Inc., which supplies expert consultancy and expert witness to the metals and related industries.
Hornby holds five patents and has authored over 136 international papers, seminars and courses. She is a Fellow of the Institute of Materials, Minerals and Mining (IoM3) and was their 2022 Hadfield Medal and Prize winner. In 2020, she was the recipient of the AIST Benjamin Fairless Award (AIST/AIME) and the AIST John Bell Award (AIST Electric Steelmaking Technology Committee). In November 2023, she was awarded an Honorary Doctorate in Engineering by SHU in recognition of her outstanding contribution to engineering and the international steel industry.
