Understanding the Carbon Footprint of Steel Production

Traditional steelmaking, primarily reliant on blast furnaces, is an energy-intensive process with a substantial carbon footprint. The blast furnace process involves smelting iron ore with coke (a carbon-rich fuel derived from coal) at extremely high temperatures. This process is inherently carbon-intensive, contributing significantly to global CO2 emissions.

The environmental impact of this traditional method is significant:

• High energy consumption in blast furnaces: Maintaining the high temperatures required for smelting consumes vast amounts of energy, primarily from fossil fuels.
• Significant CO2 emissions from coke production: Coke production itself is a major source of CO2 emissions, releasing substantial amounts of greenhouse gases into the atmosphere.
• Contribution to air and water pollution: Blast furnaces also contribute to air and water pollution through the release of particulate matter and other pollutants.

The urgent need for decarbonization has led to the emergence of "green steel," a term referring to steel produced with significantly reduced carbon emissions. Green steel production methods aim to minimize the environmental impact of steelmaking throughout its entire lifecycle, from raw material sourcing to finished product.

Eramet's eraLow Manganese Alloy: A Key Innovation

Eramet's eraLow manganese alloy represents a significant breakthrough in sustainable steel production. This innovative alloy boasts a unique composition, carefully designed to optimize steelmaking processes and reduce carbon emissions.

Key features and benefits of eraLow include:

• Lower manganese content compared to traditional alloys: The reduced manganese content allows for greater efficiency in the steelmaking process, minimizing energy consumption and CO2 emissions.
• Improved efficiency in steel production processes: The optimized composition of eraLow leads to improvements in steel production yields and overall efficiency, directly impacting carbon emissions.
• Reduced energy consumption during steel manufacturing: By optimizing the steelmaking process, eraLow contributes to lower energy consumption, further reducing the carbon footprint.
• Potential for lower emissions during the entire steel lifecycle: From raw material extraction to manufacturing and transportation, eraLow's properties contribute to a lower carbon footprint throughout the entire steel lifecycle.

The Role of Manganese in Steel Production and its Impact on Decarbonization

Manganese is a crucial element in steelmaking, contributing significantly to its strength, hardness, and other essential properties. However, traditional manganese sourcing and its incorporation into steel can have significant environmental consequences. Mining and processing manganese ore are energy-intensive activities that contribute to greenhouse gas emissions.

Eramet's innovative approach with eraLow minimizes these negative effects:

• Manganese's crucial role in steel strength and properties: Manganese remains essential for steel quality, but eraLow optimizes its usage.
• Traditional manganese sourcing and its environmental footprint: Traditional methods often lead to significant environmental damage.
• Eramet's sustainable manganese sourcing strategies: Eramet actively works on sustainable sourcing, minimizing environmental impacts associated with raw material extraction.

Benefits of Using eraLow Manganese Alloy for Sustainable Steel Production

Adopting eraLow offers significant environmental and economic advantages:

• Reduced CO2 emissions per ton of steel produced: The alloy's unique composition directly translates to a lower carbon footprint.
• Cost-effectiveness compared to other decarbonization methods: Compared to other methods of reducing carbon emissions, eraLow offers a cost-effective solution.
• Improved steel quality and performance: Despite the reduced manganese content, eraLow maintains or even improves the quality and performance of the resulting steel.
• Enhanced sustainability credentials for steel manufacturers: Using eraLow allows steel producers to enhance their sustainability profile, meeting increasing consumer and regulatory demands for low-carbon products.
