Outotec Circored® Hydrogen-based Reduction

Based on over 60 years of experience in fluidized bed technology, Outotec has developed the hydrogen-based Circored® process which produces highly metalized direct reduced iron (DRI) or hot briquetted iron (HBI) for direct feed into electric arc steelmaking furnaces. Our process reduces energy consumption and emissions, offering a sustainable solution for the future of steel-making.

  • Direct use of iron ore fines without prior agglomeration, such as pelletizing or sintering.
  • Operation with hydrogen as reductant enables reduction with very low CO2 emission values, and allows the application of low reduction temperatures minimizing sticking tendencies.
