1. A process for hybrid carbon capture and mineralization, the process comprising:
providing flue gas to react with an amine solution to produce carbamate;
processing the carbamate to regenerate amine and to produce carbonates;
treating reject brine to provide ready-made brine for carbonation reaction;
processing the carbamate with salt from treating reject brine to produce a carbonate;
precipitation of a solid carbonate from a liquid phase;
separating the solid carbonate from the amine solution; and
washing the solid carbonate and drying the washed solid carbonate to produce the carbonate.
