Brazil: Norway-based Norsk Hydro and the Federal University of Para (UFPA) have announced their collaboration on the development of a low-carbon cement from bauxite residue from Norsk Hydro subsidiary Alunorte’s bauxite mining and alumina refining operations in the state of Pará. Electronic News has reported that the research partnership hopes to develop a new cement for commercial production and sale by 2030. This will use an estimated 500,000t/yr of waste bauxite residue.
Norsk Hydro bauxite and alumina research and development senior manager Erik Araujo said, “Hydro seeks to be a benchmark in sustainability in the aluminium industry. The research is an opportunity to promote intersectional advances in our environmental management, with a reduction in carbon emissions for the cement industry.
