Mineral carbonation of red gypsum for carbon dioxide sequestration
Reduction of carbon dioxide (CO2) emissions into the atmosphere is a key challenge in order to mitigate the anthropogenic greenhouse effect. A CO2 emission causes lots of problems to human health and increases the global warming, CO2-uptake decreases these environmental issues. Mineral carbonation p...

Reduction of carbon dioxide (CO2) emissions into the atmosphere is a key challenge in order to mitigate the anthropogenic greenhouse effect.
