To make the type of gains the steel industry has demonstrated in the past in CO2 reduction, the industry must develop new steelmaking processes whose designs emit much less CO2. This means using different and greener fuels, completely different process using the green fuels, and/or developing carbon capture and sequestration technologies.
Steel is integral to a modern society that has a high quality of life. From the cars we drive, to the bridges we cross, packing the foods we eat, the appliances we use to the buildings that we live and work in. All of these steels will be recycled and re-appear as even better products ensuring a safe and secure future.
Recycling is the connection of steel's sustainability. Steel is continuously recyclable, which means it can be recycled over and over with no loss of performance.
As, more and more attention is being given to the life cycle impact of materials there is a renewed focus on the Life Cycle Assessment for consumer goods. Whether it's the cans we eat from or the cars we drive, the impact of material production matters.
