Production of manganese alloys is an energy intensive process associated with high carbon consumption. In the wake of the Paris agreement, ferromanganese producers have implemented new strategies to minimize the environmental footprint of smelting and refining activities. At Eramet Norway, process decarbonization is well underway with the goal to reduce CO2 emissions by 43% within 2030. Initiatives cover the full FeMn process range, starting from the assessment of carbon neutral reagents and pre-processing of the manganese ore to downstream reuse of furnace offgas as energy vector. In collaboration with a rich grid of academic and industrial partners, Eramet Norway is especially investigating solutions for carbon capture and storage from ferromanganese furnace gases. Technical challenges are associated with the presence of deleterious components in the flue gas as well as process discontinuities, while economic feasibility is relying on maximizing upscale efficiencies, developing downstream networks and securing governmental support.
