Germany/Brazil: Researchers at the Martin Luther University Halle-Wittenberg in Saxony-Anhalt and the University of Pará in Pará have produced a cement alternative with 66% reduced CO2 emissions. A type of calcium sulphoaluminate cement, it replaces up to 60% of limestone in clinker with overburden from bauxite mining. Researchers demonstrated that the resulting product conforms to all standards for commercial Ordinary Portland Cement. The results of the research have been published in ‘Sustainable Materials and Technologies.’
