Sweden’s Cementa and university test use of algae to reduce carbon emissions

Swedish cement company Cementa is collaborating with Linnaeus University (Linnéuniversitetet) in Småland in a research project to use algae to reduce the CO2 emissions from cement production. This is one of several methods that Cementa is exploring to reduce its CO2 emissions and to reach is target of zero CO2 emissions by 2030.
