Presentation: Engineering Group: Can we speed up weathering to help prevent climate change?
9. October 2019, London / UK
"Technologies that propose to remove CO2 from the atmosphere by chemical reaction with natural or artificial minerals are included in literature assessments of negative emissions, but have received substantially less attention compared to other proposals. This may include a range of ideas from crushing/grinding natural silicate rocks and spreading the mineral dust onto agricultural fields, or reacting carbon dioxide with alkaline waste materials (e.g. blast furnace slag).
This presentation will explore this emerging field, and the important role that professional and academic geoscientists may play in it."
