The Environmental Impact of Traditional Steel Production

Traditional steel production methods are inherently energy-intensive and heavily reliant on fossil fuels, resulting in substantial greenhouse gas emissions. The process is carbon-intensive at multiple stages:

• High CO2 emissions from blast furnaces: Blast furnaces, the traditional method of ironmaking, rely on coke (derived from coal) as a reducing agent. This process generates vast amounts of CO2.
• Significant energy consumption during steelmaking: The conversion of iron into steel requires substantial energy input, often from fossil fuel-powered sources.
• Reliance on fossil fuels for energy: The overall energy demand of steel production heavily relies on fossil fuels, leading to significant CO2 emissions across the entire supply chain. This includes the transportation of raw materials and finished products. Reducing these emissions is a critical challenge for the industry. The carbon emissions steel production generates represent a significant environmental burden.

How eraLow Manganese Alloy Reduces Carbon Emissions

Eramet's eraLow manganese alloy plays a pivotal role in reducing carbon emissions during steel production. Its unique properties allow steelmakers to achieve significant improvements in efficiency and sustainability:

• Improved steel quality with less manganese needed: eraLow's superior performance means that less manganese is required to achieve the desired steel quality. This translates directly to reduced energy consumption in the mining and processing of manganese ore.
• Reduced energy consumption in the steelmaking process: Because of its enhanced properties, eraLow contributes to a more efficient steelmaking process, requiring less energy overall. This lowers both operational costs and the carbon footprint.
• Lower emissions during steel production: The combined effect of reduced manganese usage and lower energy consumption results in a demonstrably lower carbon footprint for the steel produced with eraLow.
• Potential for increased use of scrap steel: Using eraLow can facilitate the increased use of recycled scrap steel in the steelmaking process, further reducing the reliance on primary raw materials and lowering emissions. This contributes to a circular economy model in steel production.

Benefits Beyond Carbon Reduction: Improved Steel Properties with eraLow

Beyond its environmental benefits, eraLow also offers significant improvements in the properties of the resulting steel:

• Enhanced mechanical strength: Steel produced with eraLow exhibits superior mechanical strength, making it suitable for high-performance applications.
• Improved weldability: The alloy's composition enhances the weldability of the steel, reducing welding defects and improving overall quality.
• Increased formability: eraLow contributes to improved formability, making the steel easier to shape and process, reducing energy and waste.
• Better corrosion resistance: In certain applications, eraLow also contributes to enhanced corrosion resistance, extending the lifespan of the final steel product.

Case Studies and Real-World Applications of eraLow

Eramet is actively working with partners across various sectors to demonstrate the effectiveness of eraLow. While specific project details might be confidential, we can highlight the general positive impacts:

• Example 1: Several automotive manufacturers are integrating eraLow into their high-strength steel components, leading to a measurable reduction in CO2 emissions during vehicle production.
• Example 2: In the construction industry, eraLow is being used in reinforcing bars, contributing to stronger and more sustainable infrastructure projects. The improved properties also lead to less material needed per project.
