Direct measurement of CO2 drawdown in mine wastes and rock powders: Implications for enhanced rock weathering published in the International Journal of Greenhouse Gas Control.
An excellent publication authored by Amanda Stubbs, Carlos Paulo, and our colleagues at the University of Alberta, Sasha Wilson, Baolin Wang, and Nina Zeyen. For her Master’s thesis, Amanda carried out many experiments measuring CO2 drawdown into rock powders and kimberlite mine wastes using LI-COR CO2 flux system. She tested a range of rock types while tracking changes in moisture and analyzing many samples for total inorganic carbon. Her paper will interest folks working on negative emissions technologies, particularly enhanced rock weathering and CO2 mineralization within mine wastes. Great job, Amanda!
