从黑色枷锁到绿色建材 煤基固废上演“变形记”

Core Viewpoint - The transformation of coal-based solid waste from a burden to a resource is essential for environmental protection and clean coal production, with innovative technologies paving the way for sustainable utilization [1][2][3] Group 1: Industry Overview - Traditional methods of handling coal-based solid waste primarily involve landfilling, leading to significant environmental pollution and land occupation [1] - Approximately 1.5 billion tons of new coal-based solid waste is generated annually in China, making it the largest industrial solid waste category [1] - The lack of mature resource utilization technologies and poor market effects hinder the large-scale and high-quality utilization of coal-based solid waste [1] Group 2: Technological Innovations - A new production line for coal-based solid waste preparation, designed by a research team from Xi'an University of Architecture and Technology and funded by Shaanxi Building Materials Technology Group, has been successfully launched, producing 600,000 cubic meters of cloud concrete annually [1][2] - The team has developed key technologies for low-carbon building materials from coal-based solid waste, establishing three industrial demonstration lines [2] - The cloud concrete project in Shenmu can process 600,000 tons of solid waste annually, generating over 100 million yuan in sales and more than 20 million yuan in profit [2] Group 3: Future Prospects - The ongoing innovation in technology and the establishment of representative solid waste resource utilization factories are crucial for bridging the gap between laboratory research and industrial application [3] - The team aims to continue enhancing technology research and industrial transformation, promoting a deep integration of production, education, and research to turn waste into valuable resources [3]
