Key Sustainable Practices in Green Steel Production

1. Use of Renewable Energy
– Hydrogen-Based Reduction: Replacing carbon-intensive coking coal with hydrogen to reduce iron ore.
– Electric Arc Furnaces (EAFs): Utilizing electricity, preferably from renewable sources, to melt scrap steel.
2. Recycling and Circular Economy
– Scrap Steel Recycling: Using recycled steel scrap significantly reduces the need for raw materials and energy consumption.
– Circular Economy Models: Designing products for longevity, reuse, and eventual recycling to minimize waste.
3. Carbon Capture and Storage (CCS)
– CCS Technologies: Capturing CO2 emissions from steel plants and storing them underground or utilizing them in other industrial processes.
4. Energy Efficiency Improvements
– Advanced Manufacturing Techniques: Implementing precision manufacturing to reduce energy consumption.
– Heat Recovery Systems: Capturing and reusing waste heat generated during production.
5. Sustainable Sourcing of Raw Materials
– Eco-Friendly Mining Practices: Adopting less invasive mining techniques and rehabilitating mining sites.
– Sourcing Recycled Materials: Prioritizing the use of recycled raw materials over newly mined resources.
