Institute of Energy and Fuel Processing Technology (ITPE) have recently produced carbon agglomerates that are showing high promise for applicability in manganese (Mn) production. The agglomerates were produced using BTG’s innovative bio-binders, and experiments at ERAMET and SINTEF have demonstrated that the agglomerates perform remarkably well in terms of both mechanical strength and reactivity, two key parameters determining their suitability for use in metallurgical processes. The consortium is now considering moving ahead with early piloting at Technology Readiness Level 6 (TRL6), several months ahead of schedule.
These encouraging outcomes represent a major step forward toward one of MECALO’s central technical objectives: to validate the properties of H₂-looped carbon raw materials for Mn production. By successfully combining bio-based binders with carbon powders, the project partners are developing more sustainable raw materials that can reduce the reliance on fossil-based carbon sources in the metallurgical industry. This approach aligns with MECALO’s overarching vision to foster circularity, resource efficiency and lower carbon emissions in metal production chains.
The collaboration between ERAMET, SINTEF, ITPE and BTG has been key to reaching this milestone. Each partner has contributed complementary expertise, from materials engineering and binder formulation to testing and performance analysis, resulting in a well-rounded and robust validation process. The positive results also demonstrate the feasibility of integrating renewable carbon sources into high-temperature metallurgical operations without compromising material performance.
Encouraged by these findings, the consortium is now considering advancing to TRL6 trials several months ahead of schedule. This acceleration reflects both the maturity of the research and the confidence gained through the collaborative testing phase. The upcoming trials will focus on demonstrating the scalability and consistency of the process under conditions closer to industrial application, paving the way for future implementation within the metallurgical sector. Overall, this achievement confirms MECALO’s strong progress toward its goals and highlights the potential of hydrogen-looped, bio-based carbon materials to contribute to a more sustainable and resilient European metal production landscape
