| Abstract |
Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO2-concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO2-levels. This can be applied as a technology, by reacting captured CO2 with olivine or calcium-silicates in autoclaves. It can also be applied extensively, by spreading fine-powdered olivine on farmland or forestland. Measures to control the CO2-levels of the atmosphere will be adopted more readily if they also serve some broader economic goals. An effective strategy for CO2 control will require many parallel approaches simultaneously. |
