Embodiments of a process for discharging amine byproducts formed in an amine-based solvent are provided. The process comprises the steps of contacting the amine-based solvent with flue gas comprising carbon dioxide, oxygen, nitrogen, NO, SO, or mixtures thereof to form a carbon dioxide-laden amine-based solvent that contains the amine byproducts. Carbon dioxide is separated from the carbon dioxide-laden amine-based solvent to form a carbon dioxide-depleted amine-based solvent. The amine byproducts from the carbon dioxide-depleted amine-based solvent are fed to an algae source.
