Lab-Scale Carbonation of Wood Ash for CO<sub>2</sub>-Sequestration

This study evaluated the CO<sub>2</sub> sequestration potential with combustion ashes in the aqueous phase. The aim was to provide a cost-effective carbon sequestration method for combustion unit operators (flue gas cleaning) or biogas producers (biogas upgrading). Therefore, two separat...
