The article "Breakthrough Innovations in Carbon Dioxide Mineralization for a Sustainable Future" by Ramesh Kumar, Woo Jin Chung, Moonis Ali Khan, Moon Son, Young-Kwon Park, Sang Soo Lee, and Byong-Hun Jeon discusses the importance of managing carbon dioxide (CO₂) emissions to combat climate change. The authors highlight the significance of carbon capture and storage (CCS) for safe and permanent CO₂ sequestration, as well as the potential of CO₂ utilization in developing new businesses for energy security and material production. CO₂ mineralization, which involves converting CO₂ into thermodynamically stable solid calcium or magnesium carbonates through simple chemical reactions, is presented as a promising strategy for long-term sequestration. The paper reviews current advancements in CO₂ mineralization technologies, focusing on pathways and mechanisms using industrial solid wastes and natural minerals. However, it also identifies major barriers such as operating costs, energy consumption, reaction rates, and material management. The authors emphasize the need for optimizing operating parameters, developing tailored equipment, and ensuring a smooth supply of waste feedstocks to make the carbon mineralization process economically and commercially viable. They also discuss the integration of industrial wastes and brine with CO₂ mineralization to explore novel chemical pathways for the synthesis of valuable metal recovery and sustainability goals. The graphical abstract and abbreviations are provided, and the introduction outlines the burning of fossil fuels as a major source of atmospheric CO₂ and the challenges in replacing them with renewable energy in industries like steel and cement production.The article "Breakthrough Innovations in Carbon Dioxide Mineralization for a Sustainable Future" by Ramesh Kumar, Woo Jin Chung, Moonis Ali Khan, Moon Son, Young-Kwon Park, Sang Soo Lee, and Byong-Hun Jeon discusses the importance of managing carbon dioxide (CO₂) emissions to combat climate change.
