The steel industry is at the center of the global energy and climate transition. Achieving net-zero emissions requires a portfolio of innovative technologies, from carbon capture to hydrogen reduction, electrolysis, biomass, efficient raw material use, and circular economy strategies like scrap recycling and co-product valorization.

Module Type
Microlearning
Description
This microlearning focuses on scrap as the world’s most recycled material and a critical input for steelmaking. Learners will discover how scrap is used in both BF-BOF and EAF routes, its environmental benefits in reducing emissions and resource use, and future challenges related to scrap availability and quality.
What you will learn
Identify the role of steel scrap as a critical raw material in steel production and explain how it functions in both blast furnace–basic oxygen furnace (BF–BOF) and electric arc furnace (EAF) processes.
Explain the environmental benefits of scrap use, including avoided CO₂ emissions and conservation of iron ore, coal, and limestone.
Differentiate between pre-consumer and post-consumer scrap, describing how their availability and quality influence steel recycling.
Analyze the constraints on scrap availability due to steel’s long service life (average ~40 years) and discuss projected increases in end-of-life scrap supply through 2050.
