What Is Sustainable Steel?
Sustainable steel, an eco-friendly version of traditional steel, minimizes environmental impact. It’s produced using methods that reduce carbon emissions, conserve energy, and recycle materials. Traditional steel production emits large amounts of CO2; however, sustainable steel production uses renewables and energy-efficient technologies to cut emissions significantly.
There are three main types of sustainable steel: recycled steel, electric arc furnace (EAF) steel, and low-carbon steel. Recycled steel uses scrap metal, decreasing waste and material demand. EAF steel, generated from electric arc furnaces, typically emits fewer CO2 emissions compared to blast furnaces. Low-carbon steel involves innovations like using hydrogen instead of coal, further reducing the carbon footprint.
Sustainable steel also complies with environmental standards and certifications such as LEED (Leadership in Energy and Environmental Design) and Cradle to Cradle Certified. These certifications assure that materials meet stringent environmental criteria, aligning with sustainable development goals.
Incorporating sustainable steel in eco-friendly public transport projects enhances infrastructure longevity and efficiency while supporting global sustainability efforts.
