Abstract Coal-based soild wastes (CBSWs) are industrial byproducts that can be harmful to the environment. The exploitation and utilization of CBSWs offer societal advantages such as resource conservation, pollution reduction, cost-effective production. However, environmentally sustainable management remains a worldwide challenge due substantial production volume limited disposal capacity CBSWs. physicochemical properties summarized, including fly ash, coal gangue gasification slag. It also presents current global applications status resources examines market supply demand. Subsequently, paper provides an overview studies on ways utilise CBSWs, highlighting primary avenues which mainly from fields chemical materials, metallurgy agriculture. Furthermore, comparative evaluation various methods for recovery is conducted, outlining their respective disadvantages. future development recycling processes discussed. review concludes while there growing need attention in recycling, its will involve combination both large-scale treatment refinement processes. aims references insights effective environmental protection Future direction focus collaborative emphasizing high-value utilization. In addition, establish comprehensive database based on-site practices, explore solutions reduce transportation costs, improve during process.
