Abstract. The production of one ton of alumina using the Bayer process generates 0.7–2.0 ton of Bauxite Residue (BR) and an average of 1.0 ton of CO 2.The direct use of exhaust gases to react and reduce the alkalinity of BR may allow a triple gain: improving the storage conditions, opening a range of new appliions for BR and sequester from 16 to 102 kg of CO 2 per ton of alumina.
