According to a press release dated September 10, 2025, this investment reflects Metso's commitment to developing low-carbon technologies and supporting the transition to fossil fuel-free steel production on a global scale.
The pilot plant, based on Metso's patented Circored™ technology, provides continuous pre-reduction using hydrogen as the sole reducing agent. The plant integrates preheating, reduction, gas cleaning, and recirculation systems for hydrogen and dust, while incorporating electric heaters to support near-zero carbon operation.
Parizat Pandey, Director of Direct Reduced Iron (DRI) at Metso, said, "This pilot plant is an important step in demonstrating that Circored™ technology is ready. It allows us to validate process parameters and support our customers' transition to low-carbon steel production."
A wide variety of iron ore types can be tested at the Circored™ pilot plant, providing critical process data for the engineering of future commercial-scale plants. It also helps determine the operating range for different ore qualities. The Circored™ direct reduction process can be integrated with Metso's DRI Melting Furnace or other melting technologies. Both Circored™ and DRI Melting Furnace technologies are offered as part of Metso Plus.
