煤基固废变身“绿色富矿”

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 high-value construction materials like cloud concrete stone [1][2]. Group 1: Production and Technology - The production line has an annual capacity of 600,000 cubic meters of cloud concrete stone, effectively acting as a "solid waste digester" by consuming 600,000 tons of solid waste annually [2]. - The research team has developed a comprehensive process package for recycling coal-based solid waste into microcrystalline glass, cloud concrete stone, and ceramic particles, successfully transforming "black waste" into "green building materials" [2][3]. - The team has established three industrial demonstration lines that cover various products, paving the way for large-scale and high-value utilization of coal-based solid waste [2]. Group 2: Economic and Environmental Impact - The Shenmu cloud concrete stone production line generates an average annual profit of over 20 million yuan, demonstrating the potential for waste-to-resource transformation [4]. - The projects showcase that environmental protection and economic benefits can coexist, highlighting the vast market potential for solid waste resource utilization [4]. - The initiative aligns with China's dual carbon goals, emphasizing the importance of solid waste resource utilization in environmental governance, energy security, industrial upgrading, and a low-carbon future [4].
