bluemint® Steel

With bluemint® Steel we are launching our first certified steels with reduced CO2 intensity. The CO2-reduced products are produced at the Duisburg site and give our customers the certainty to use high-quality steel with an improved ecobalance.

A portfolio that lasts

It is another important step towards a climate-neutral steel industry: Under the brands bluemint® pure and bluemint® recycled, we have added two new climate-friendly products to our portfolio since autumn 2021. The special feature: The material properties do not differ from the existing steel grades - except in their reduced specific CO2 emissions.

This is the first transformation success within the scope of our climate strategy and reflects our ambitious goal of a sustainable and customer-oriented steel production. In the coming years, we will intensively invest in innovations and technologies which will take our customers gradually further towards our common goal of climate-neutrality.

bluemint® Steel – two products, many advantages

bluemint® pure

  • Measure: Use of HBI in the blast furnace, also hydrogen in the long run
  • CO2 reductions at Duisburg production site and in a global context
  • Allocated CO2 reductions lead to reduced product-related carbon intensity
  • CO2 reduction of 1.5 tonnes of CO2 per tonne of hot strip
  • Residual carbon intensity of 0.6 tonnes of CO2 per tonne of hot strip
  • Standard: WRI/WBCSD GHG Protocol for Product Accounting
  • Certified by DNV (Link to certificate)

bluemint® recycled

  • Measure: Use of scrap in the blast furnace
  • CO2 reductions at Duisburg production site
  • Balance-sheet CO2-neutral recycling product
  • CO2 reduction of 1.35 tonnes of CO2 per tonne of hot strip
  • Specific CO2 emissions of 0.75 tonnes of CO2 per tonne of hot strip
  • Standard: DIN EN ISO/IEC 17029 and TÜV SÜD VERIsteel Standard
  • Certified by TÜV SÜD (Link to certificate)

Advantages of bluemint® Steel – at a glance

  • CO2 emissions reduced by about 1.5 tonnes (70 percent) (bluemint® pure)
  • CO2 emissions reduced by about 1.35 tonnes (64 percent) (bluemint® recycled)
  • CO2 is directly reduced at Duisburg production site
  • Certificates for the respective product
  • Primary steel, all qualities possible
  • Directly creditable against the Scope 3 emissions of our customers

bluemint® is our promise


In view of the challenges associated with climate change and the opportunities in future markets, the concept of low carbon dioxide steels is attracting the attention of many processing and end user industries. bluemint® pure is particularly attractive to customers who supply to end-user markets. bluemint® recycled is primarily targeted at customers for whom a high proportion of recycled material is important.

bluemint®– a made-up name with a meaning
blue symbolizes the power of nature, purity and our climate.
mint stands for freshness and innovation.

Certified quality


bluemint® pure and bluemint® recycled stand for the variety of our portfolio of grades. This means that you can rely on the continued availability of the familiar materials. In terms of material and processing properties, our two bluemint® Steel products fall by no means short of our existing grades. On the contrary: The high premium quality is complemented by a significant CO2 reduction.

This is substantiated by our certificates: bluemint® pure is certified by the DNV and bluemint® recycled by TÜV SÜD.
