In our previous article, we discussed the circular economy. Now, let us explore the first 'R'—reducing. Join us on a journey to understand its crucial role in fostering sustainability.
Over the last five decades, the steel industry has been investing in cutting-edge research and technology, creating super-strong steel that are also surprisingly lightweight. Why does that matter? Well, when we use these advanced steels in things like cars or buildings, we end up needing less steel overall.
Reducing the weight of products is a key part of what we call a circular economy . It's like a cool eco-friendly circle – by making things lighter, the industry has successfully decreased the consumption of raw materials and energy during the manufacturing process.
Whether it is a sleek wind turbine, a modern building, a classy car, or even a trusty steel can, using these advanced steels means we do not have to use as much steel to get the same strength and functionality.
These innovations have not only revolutionized the properties of steel but have also played a pivotal role in fostering sustainability and reducing the environmental footprint of steel production and application.
Construction and CO2 Reduction:
The substitution of high-strength steels for regular steels in construction projects has proven to be a game-changer. According to worldsteel, this switch can achieve a substantial reduction in carbon dioxide emissions, with around 30% less in steel columns and approximately 20% in steel beams. This is attributed to the decreased tonnage of steel required for the same structural function.
The impact is far-reaching, not only in terms of reduced steel consumption but also in the optimization of other materials, such as foundations. Additionally, advancements in coating systems contribute to extended service life, further diminishing the demand for materials.
Material Efficiency:
Modern steelmaking processes prioritize material efficiency, aiming to utilize raw materials to their full capacity. This commitment ensures minimal waste in steelmaking, as nearly every co-product formed during the process finds a purpose in new products. The industry produces more than 20 different co-products, including slag, which can be repurposed for cement, fertilizers, and road stone.
Water recirculation within steel plants is another integral aspect of material efficiency, with approximately 90% of water used in steelmaking being cleaned and reused or returned to its source.
The steel industry's journey towards sustainability is marked by continuous innovation, responsible resource management, and a commitment to reducing environmental impact. By embracing advanced technologies, recycling practices, and a collaborative approach, the industry is not only meeting the demands of the present but also laying the foundation for a more sustainable and environmentally conscious future.
