The article “How green steel made with electricity could clean up dirty industry”, written by Crownhart (2022), explores an alternative steel manufacturing method called green steel and its functions. With the steel industry producing 10% of the world’s carbon emission, major changes are needed to lower down the numbers, hence the invention of green steel. What is green steel? It is the process manufacturing of steel without the use of fossil fuels, which instead of using blast furnace, electricity is used to breakdown iron oxide materials and in turn emit oxygen to the atmosphere (Crownhart, 2022).
