Sugarcane-mill ash has been suggested as having high potential for carbon dioxide removal via enhanced weathering, but this had not been quantitatively assessed. The aims of this study were to 1) assess the CDR potential of various sugarcane-mill ashes via EW, and 2) investigate the impact of soil conditions and mill ash properties on the CDR. This was done by characterising physical and chemical properties of five mill ashes from Australia and simulating weathering using a one-dimensional reactive transport model.
