Inner Mongolia's first trial road built entirely with coal-based solid waste cementitious materials recently began construction in the Tuke Project Zone of Ordos Sulige Economic Development Zone. Stretching 220 meters long and 17 meters wide, this project marks a significant leap forward in Ordos' efforts to recycle coal-based solid waste.
Sulige Economic Development Zone has partnered with several companies and Southeast University's environmental geotechnical experts to develop the "coal-based solid waste road recycling technology." This addresses issues such as land encroachment and environmental contamination from the buildup of coal chemical waste, and fosters a green, low-carbon transition.

The project primarily utilizes coal gasification slag as its primary material and integrates various industrial solid wastes, including fly ash and desulfurized gypsum. It has developed a road base material with a 100-percent solid waste ratio, offering high strength and durability while reducing reliance on traditional sand, gravel, and cement. The construction process is also innovative, forming a comprehensive technical system that lays the groundwork for large-scale promotion.
Environmentally, the recycling rate of industrial solid waste will surge to over 70 percent, with each kilometer of road consuming roughly 6,000 metric tons of solid waste, drastically reducing land use and environmental hazards. Economically, construction expenses will decrease by over 30 percent through the substitution of traditional materials. Socially, it will provide a replicable "Ordos Model" for areas with dense industrial solid waste, propelling infrastructure toward green transformation.

The project team will continue to optimize the technological path, expand application areas, deepen the integration of technology and industry chains, and accelerate the transformation and industrialization of achievements, empowering green, low-carbon, high-quality development.
