Summary Reader Response ( Green Steel ) ( Draft 2 )
The article “How green steel made with electricity could clean up a dirty industry" by Crownhart (2022) showed that fossil fuels are quintessential in the production of steel, being heated in blast furnaces. This reacts with the impure iron ores, which contain iron oxides and other minerals, removing the oxygen and leaving liquid iron. The byproduct of this process is released as carbon dioxide, which is harmful to the environment as it absorbs the sun’s energy and an excess of this gas will lead to global warming.
