Researchers from Makerere University’s College of Engineering, Design, Art and Technology (CEDAT), in collaboration with the Technical University of Denmark (DTU), have conducted a study exploring ammonia-based technology as a cleaner alternative for iron and steel production.
The team was comprised of Medard Turyasingura, Basit Ali, Michael Lubwama, Peter Wilberforce Olupot, and Marcel A. J. Somers.
The research, titled “Thermodynamics and Kinetics of Ammonia-Based Reduction of Natural Hematite,” was published in Steel Research International in 2026, was based on using natural iron ore sourced from Buhara Sub-County, Kabale District, where the researchers investigated ammonia’s effectiveness in converting iron ore into metallic iron. Laboratory experiments achieved over 98% apparent reduction at 850°C, demonstrating the technology’s potential for cleaner iron production.
Potential Impact on Ugandan Communities
The research presents opportunities for Uganda to harness its abundant iron ore resources for local industrial development. If successfully developed for commercial application, the technology could support job creation, skills development, local manufacturing, and increased incomes in mining communities and related industries. Cleaner iron production could also contribute to reducing industrial carbon emissions, supporting environmental protection and community well-being. Increased local processing of iron ore could strengthen Uganda’s construction and manufacturing sectors while reducing dependence on imported steel.
Advancing Sustainable Industrialisation
The findings provide a scientific foundation for further research into affordable, environmentally sustainable iron production. However, additional investigations are needed to assess industrial feasibility, production costs, and environmental risks, including nitrogen oxide emissions.
