Core Points - The completion of the Wuma Expressway from Huinong to Shizuishan in Ningxia marks the full connectivity of the Wuma Expressway in the region, utilizing over 3.8 million tons of industrial solid waste, achieving both economic and ecological benefits [1][2] - The project addresses the challenge of solid waste accumulation in Ningxia, where the energy and chemical industries generate thousands of tons of industrial waste annually, while traditional road construction materials are costly due to a lack of sand and gravel resources [1][2] - The project has developed 15 key technologies to enhance the utilization of industrial solid waste, creating a new type of material that is more durable than high-strength concrete, with a crack rate reduced by 70% compared to traditional materials [2][3] Industry Standards and Innovations - Ningxia has established a set of replicable standards and models for material and construction processes, including 10 local standards that fill industry gaps [3] - The use of solid waste in road construction has also contributed to ecological remediation, with over 1 million tons of coal gangue being utilized and nearly 500 acres of previously contaminated land being restored [3] - The project is expected to save nearly 3 million tons of sand and gravel, 80,000 tons of cement, and reduce carbon emissions by over 60,000 tons [3] Future Plans - Ningxia plans to replicate the project's success in new projects like the Yinkun Expressway and explore further applications of solid waste materials in the construction sector [3] - The region aims to achieve a 75% comprehensive utilization rate of industrial solid waste by 2030, emphasizing continuous technological innovation to enhance resource utilization and reduce costs in infrastructure development [3]

Core Viewpoint - The completion of the Wuma Expressway segment in Ningxia marks a significant achievement in utilizing industrial solid waste for road construction, promoting both economic and ecological benefits [1][3]. Group 1: Project Overview - The Wuma Expressway segment from Huinong to Shizuishan spans 57 kilometers and has been constructed using over 3.8 million tons of industrial solid waste, including fly ash, coal gangue, and slag [1]. - This project is recognized as one of the first national green low-carbon advanced technology demonstration projects [1]. Group 2: Technological Innovations - The technical team conducted extensive research, sampling over 20,000 samples from more than 30 factories along the route, discovering that industrial solid waste has advantages such as higher compressive strength and wear resistance compared to traditional materials [2]. - A total of 15 key technologies were developed, including a method to create a "super concrete" by mixing eight types of solid waste with self-developed green cementing materials, resulting in a material that outperforms high-strength concrete [2]. Group 3: Environmental Impact - The project has led to the comprehensive utilization of over 1 million tons of coal gangue, restoring nearly 500 acres of land previously contaminated by coal gangue [3]. - The use of over 3.8 million tons of industrial solid waste has saved nearly 3 million tons of sand and 80,000 tons of cement, while reducing carbon emissions by over 60,000 tons [3]. Group 4: Future Plans - Ningxia plans to replicate the successful experience of this project in new initiatives such as the Yinkun Expressway and explore further applications of solid waste materials in the construction sector [3]. - The goal is to achieve a comprehensive utilization rate of industrial solid waste of 75% by 2030, supported by ongoing technological innovation [3].
