Exploring a new promising path towards Sustainable Cement Production
" ReActiv proposes a win-win scenario for both industrial sectors: reducing waste and CO2 emissions "
The ReActiv project will create a novel sustainable symbiotic value chain, linking the by-product of the alumina production industry with the cement production industry. Bauxite residue (BR) is the main by-product of the alumina sector produced at rates of 7 million tons per year in the European Union, while recycling rates are less than 100 thousand tons per year respectively. In the ReActiv project, certain modifications will be made to both the alumina production and the cement production side of the chain, in order to link them through the new ReActiv technologies.
The latter will modify the properties of the industrial residue, transforming into an active material (with pozzolanic or hydraulic activity) suitable for new, low CO2 footprint, cement products. In this manner ReActiv proposes a win-win scenario for both industrial sectors : reducing wastes and CO2 emissions respectively.
