| Abstract | With the rapid development of economy and industrialization, the consumption of natural resources has risen sharply. A large number of greenhouse gases and industrial solid waste emissions have exacerbated global warming, resulting in a series of environmental degradation problems. Using natural minerals or industrial solid waste for carbon dioxide capture and utilization (CCU) is considered to be a feasible and promising technology. From the perspective of circular economy, steel-making slag as carbon dioxide storage material has great eco-nomic and environmental value. This paper summarized the main carbonation pathways and carbon capture mechanisms of industrial solid wastes. The carbonation processes of the most representative solid waste of steel-making slags were compared, the effects of different carbonation pathways on the carbonation capacity of steel-making slags were evaluated, and the characteristics of carbonation products obtained from different carbon-ation pathways were also compared. In addition, the industrial application status of carbon dioxide carbonation technology of steel-making slags was analyzed, and the main challenges it faces were summarized and pro-spected. We hope that this review can attract extensive attention of scholars and promote the further develop-ment of carbon dioxide storage technology by mineralization of steel-making slag. |
