Understanding the Carbon Footprint of Steel Production

Conventional steelmaking, primarily through blast furnaces and electric arc furnaces (EAFs), is inherently energy-intensive and carbon-heavy. The process involves several stages, each contributing to substantial CO2 emissions. Blast furnaces, for example, rely heavily on coal-based coke as a reducing agent, generating significant direct emissions of CO2 during the iron-making process. Additionally, the high temperatures required in both blast furnaces and EAFs necessitate substantial energy consumption, often relying on fossil fuels for electricity generation. This leads to indirect CO2 emissions from the power sector.

Key sources of greenhouse gas emissions in steelmaking include:

• Coal-based coke production: The production of coke from coal is a highly energy-intensive and emissions-rich process.
• High energy consumption: The smelting and refining stages demand vast amounts of energy, mostly from fossil fuel sources.
• Direct emissions from chemical reactions: Chemical reactions within the furnace release CO2 and other greenhouse gases.
• Indirect emissions from electricity generation: Steel mills often rely on electricity grids powered by fossil fuels, adding to the overall carbon footprint.

How eraLow Manganese Alloy Reduces Carbon Emissions

Eramet's eraLow Manganese Alloy offers a compelling solution to mitigate these emissions. Its unique properties allow for significant reductions in the carbon intensity of steel production. The alloy's optimized composition enhances the efficiency of steelmaking processes in several crucial ways:

• Improved efficiency in steelmaking processes: eraLow Manganese Alloy allows for reduced energy needs in the refining process, directly lowering energy consumption and associated CO2 emissions.
• Enhanced productivity: The improved properties of the alloy lead to less overall steel production required for a given application, resulting in a smaller overall carbon footprint.
• Potential for increased scrap utilization in electric arc furnaces: The alloy's properties facilitate higher levels of scrap utilization in EAF steelmaking, further reducing the need for primary iron production.
• Reduced reliance on high-carbon iron ore sources: By optimizing the steelmaking process, the alloy contributes to a reduction in the dependence on high-carbon iron ore sources.

The Benefits of Using eraLow Manganese Alloy Beyond Decarbonization

The advantages of using eraLow Manganese Alloy extend beyond its environmental benefits. Its unique metallurgical properties contribute to improved steel quality and cost-effectiveness:

• Improved formability and weldability: This leads to easier processing and reduced manufacturing waste.
• Increased strength and toughness: resulting in lighter, stronger, and more durable end products.
• Enhanced corrosion resistance: Extending the lifespan of steel components and reducing the need for frequent replacements.
• Potential for cost savings: Increased efficiency and reduced material usage translate to potential cost savings for steel producers. These cost savings can further incentivize wider adoption. The alloy finds applications in diverse sectors, including automotive, construction, and energy.

Case Studies and Real-World Applications of eraLow Manganese Alloy

While specific case studies with quantifiable emission reductions may be confidential or not yet publicly available, the inherent properties of eraLow Manganese Alloy strongly suggest significant environmental gains. The improved efficiency and reduced material usage directly translate to lower energy consumption and reduced CO2 emissions in the overall steelmaking process. Eramet is actively collaborating with steel producers to implement and track results, and further data will likely become available over time.
