Core Viewpoint - The article highlights the establishment of China's first carbon-based solid waste pilot base in Yulin, which transforms coal gangue into eco-friendly soil, addressing the significant issue of coal gangue waste management in the region [1][3]. Group 1: Background and Necessity - Yulin produces over 60 million tons of coal gangue annually, accounting for more than 50% of industrial solid waste, with a low comprehensive utilization rate of less than 40% [3][4]. - Traditional disposal methods for coal gangue, such as producing sintered bricks and cement additives, are costly and have limited market absorption, leading to insufficient resource utilization [4]. Group 2: Technological Innovation - The pilot base utilizes a new technology developed by the Chinese Academy of Sciences, which couples intelligent sorting of coal gangue with microbial degradation for comprehensive utilization [4][6]. - This technology aims to create eco-functional soil that can restore degraded land and support ecological restoration while facilitating large-scale utilization of coal gangue [6]. Group 3: Future Prospects - The pilot base has established a production line capable of producing eco-functional soil at a scale of 10,000 tons, attracting interest from investors and stakeholders across various regions [6]. - The project aims to expand the direction of carbon-based solid waste resource utilization in Shaanxi and provide technical support for comprehensive utilization of coal gangue nationwide [6].
