Rinder, Thomas; Hagke, Christoph von (2021): The influence of particle size on the potential of enhanced basalt weathering for carbon dioxide removal - Insights from a regional assessment

Rinder, Thomas; Hagke, Christoph von (2021): The influence of particle size on the potential of enhanced basalt weathering for carbon dioxide removal - Insights from a regional assessment. In Journal of Cleaner Production 315, p. 128178. DOI: 10.1016/j.jclepro.2021.128178.

"It has been shown that enhanced weathering is principally feasible on a global scale, but there is still uncertainty with respect to the predicted drawdown in a given timeframe. This information is however vital to evaluate, if enhanced weathering should be further considered as a factor to alleviate the impact of the climate crisis. With this in mind, this article reviews of the current state of research and estimates the CO2 drawdown for scenarios using basalt powders of different particle size distribution (<100 μm, <10 μm and <1 μm)."

Choi, Woo-Jung; et al. (2021): Environmental Risks in Atmospheric CO2 Removal Using Enhanced Rock Weathering Are Overlooked

Choi, Woo-Jung; Park, Hyun-Jin; Cai, Yanjiang; Chang, Scott X. (2021): Environmental Risks in Atmospheric CO2 Removal Using Enhanced Rock Weathering Are Overlooked. In Environmental science & technology. DOI: 10.1021/acs.est.1c02505.

"The risks and limitations of ERW should be clearly recognized and a strategy for the pragmatic use of ERW for CO2 removal needs to be developed for policy makers."

Belmonte, Beatriz A.; et al. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks

Belmonte, Beatriz A.; Aviso, Kathleen B.; Benjamin, Michael Francis D.; Tan, Raymond R. (2021): A fuzzy optimization model for planning integrated terrestrial carbon management networks. In Clean Techn Environ Policy, pp. 1–13. DOI: 10.1007/s10098-021-02119-7.

"Although recent papers have reported the development of process integration models for optimizing carbon management networks based on either biochar application or enhanced weathering, none have reported models integrating these two NETs in the same system. To address this gap, a fuzzy mixed-integer linear programming model is developed that integrates biochar application and enhanced weathering for large-scale carbon sequestration."

Call for Abstracts: Enhanced Weathering and Synergistic Combinations with Other CDR Methods (Frontiers Research Topic)

Deadline: 30. September 2021

"This special collection encourages submissions to this broad application scheme of EW and welcomes contributions on laboratory experiments, greenhouse experiments as well as field trials. We also encourage submissions on modelling studies, as predictions about the efficiency of CDR, impacts on soil functioning and biological uptake of released elements by EW need improvements, such that in the future EW in combination with other CDR options can be applied in a sustainable way."

Aviso, Kathleen B.; et al. (2021): Fuzzy optimization model for enhanced weathering networks using industrial waste

Aviso, Kathleen B.; Lee, Jui-Yuan; Ubando, Aristotle T.; Tan, Raymond R. (2021): Fuzzy optimization model for enhanced weathering networks using industrial waste. In Clean Techn Environ Policy, pp. 1–17. DOI: 10.1007/s10098-021-02053-8.

"To fill this research gap, this work develops a fuzzy mixed-integer linear programming model for optimal planning of enhanced weathering networks. The model is capable of handling multiple conflicting objectives and accounting for system uncertainties."
