Influence of selected CO2 absorption promoters on the characteristics of calcium carbonate particles produced by carbonation of the post-distillation liquid from the Solvay process

Study of the Effect of Leucine on Calcium Carbonate Precipitation in a Circular Economy Perspective

“…This route ensures effective recycling of both gaseous CO 2 and liquid industrial waste, turning CO 2 into a final product of industrial interest, which is in line with a circular economy approach [8]. An industrial example is the postdistillation liquid from the Solvay Process (production of sodium carbonate, soda-ash), that is a Ca-rich waste [9]; if not correctly disposed of, this waste is responsible for the strong salinity of nearby groundwater with calcium chloride pollution of natural water reservoirs and soil [10]. Instead, this liquid waste can be used for CaCO 3 precipitation with CO 2 utilization [11].…”

Amino acid promoted single-step carbon dioxide capture and mineralization integrated with polymer-mediated crystallization of carbonates

“…Hence, single-step integrated CO2 capture and mineralization process with amino acid at ambient conditions needs to be further explored to achieve a high extent of mineralization in a shorter time. Furthermore, precipitated CaCO3 is used in various products, such as a pigment or filler in paper, plastics, and rubber, and in cosmetics to improve rheology, physical robustness, or visual appearance (Czaplicka et al, 2021). The morphological properties of CaCO3 can be tuned by biomimetic polymer-mediated crystallization giving them functional features to extend its application horizon further (Xu et al, 2007).…”
