  USC1001 - Summary Reader Response Draft 3 Subject: Green Steel Student Name:  Lim Yan Chen Student ID: 2201776 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, to be heated in blast furnaces. This reacts with the impure iron ores, containing iron oxides and other minerals, removing the oxygen and leaving liquid iron. The byproduct of this process is released as carbon dioxide, a greenhouse gas that is harmful to the environment. According to Casey (2022), traditional steel-making produces around two tons of carbon dioxide emissions for every ton of steel produced, which is 10% of all carbon dioxide emissions worldwide. As the global steel market is set to expand around 30% by 2050, there is a need for alternative green methods as some of the largest steelmakers have since pledged to reach zero-emissions by the same date.  In the same article, Boston Met

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, to be heated in blast furnaces. This reacts with the impure iron ores, containing 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.  According to Casey (2022),  traditional steel-making produces around two tons of carbon dioxide emissions for every ton of steel produced, which is 10% of all carbon dioxide emissions worldwide.
