ABSTRACT
The development of sustainable technologies for the utilization of coal gasification fine slag (CGFS) has garnered significant attention due to the material's potential as an alternative resource in various industrial applications. Recent studies have focused on CGFS's use in energy recovery, heavy metal adsorption, electromagnetic shielding, and cement-based materials, as well as its interactions with other industrial wastes. This review synthesizes findings from the most recent literature, including advancements in the gasification process, co-combustion techniques, and the efficient removal of contaminants through CGFS-based adsorbents. The literature reveals the role of CGFS in mitigating environmental pollution through the treatment of toxic heavy metals, CO2 capture, and reducing greenhouse gas emissions. Additionally, its potential in the synthesis of advanced composite materials, such as electromagnetic shielding and heat management composites, is explored. We also address the challenges associated with its management, such as its effect on soil quality, water contamination risks, and potential for resource recovery. This review concludes by highlighting emerging applications and providing a comprehensive analysis of future research directions. The findings will serve as a guide for researchers and practitioners seeking to maximize the environmental benefits of CGFS while addressing its disposal challenges.
