Core Viewpoint - The establishment of a coal-based solid waste resource utilization production line in Shenmu City, Shaanxi Province, marks a significant step towards the industrialization of coal-based solid waste recycling in China, utilizing waste materials such as fly ash and coal gangue to produce low-carbon building materials [1][2]. Group 1: Production and Technology - The production line has an annual capacity of 600,000 cubic meters of cloud concrete stone, effectively transforming solid waste into high-value building materials [1][2]. - The research team has developed a comprehensive process package for recycling coal-based solid waste into microcrystalline glass, cloud concrete stone, and expanded clay, creating a pathway from "black waste" to "green building materials" [2][3]. - The Shenmu production line is described as a "solid waste digestive system," capable of processing 600,000 tons of solid waste annually [2]. Group 2: Economic and Environmental Impact - The Shenmu cloud concrete stone production line generates an average annual profit exceeding 20 million yuan, demonstrating the economic viability of solid waste resource utilization [3]. - The projects not only showcase the potential for environmental protection and economic benefits to coexist but also highlight the vast market for solid waste resource utilization [3]. - The initiative aligns with China's dual carbon goals, emphasizing the importance of solid waste recycling in environmental governance, energy security, industrial upgrading, and a low-carbon future [3].
