Abstract
Although human civilization has developed through genomic evolution, including its fingernail-functional cooperation, the daily lives of humans have resulted in a significant amount of carbon dioxide (CO2) being released into the atmosphere since the Industrial Revolution, which started almost 200 years ago. Recently, climate change has been documented to have spread globally. For example, terrestrial rains have caused severe floods in Europe, and one of the largest tornados in history occurred in the Kentucky region of the United States of America in 2021. Furthermore, glaciers are melting rapidly. This change is clearly due to the accumulation of CO2 in the atmosphere. Therefore, this accumulated CO2 must be eliminated as soon as possible to prevent further worsening of the climate crisis. However, CO2 reduction cannot be achieved simply by the use of solar or wind power. The concept of a carbon-neutral society by 2050 seems too late. Contrarily, CO2 can be captured experimentally from the air or from the exhaust gases through various techniques, including absorption, adsorption, and membrane separation. Adsorption with amines is currently the dominant technology, but it is not largely used because it involves the use of toxic organic solvents. Therefore, this study reports the development of an innovative method for CO2 fixation and storage. Using this method, CO2 is converted to CaCO3, limestone, or corral, a harmless natural compound, using NaOH and CaCl2. This novel method can be used to convert fossil fuels, such as coal, oil, and natural gas, into Earth components using a simple and inexpensive system without environmental concerns.
