On January 25, 2026, the Phase II phosphogypsum aggregate products production system of the Yunnan Construction Investment Anning Industrial Park project was successfully commissioned. The project is designed to process 1 million tons of phosphogypsum and 1 million tons of industrial solid waste annually, marking an important milestone in the large-scale and value-added utilization of phosphogypsum resources.
The successful commissioning demonstrates significant progress in transforming industrial byproducts into sustainable building materials. As one of the key industrial recycling projects in the region, the industrial park focuses on converting phosphogypsum from industrial waste into usable construction materials through integrated processing technologies and continuous production systems.
The Phase II production line is capable of manufacturing multiple categories of building materials, establishing a complete industrial chain that covers phosphogypsum treatment, raw material processing, aggregate production, and the manufacturing of high-value construction products. This integrated approach promotes the transition of phosphogypsum from “waste” to “resource” and further advances the development of circular economy practices within the building materials industry.
Phosphogypsum is a byproduct generated during phosphate fertilizer production. Historically, large quantities of phosphogypsum have been stockpiled, creating environmental and land-use challenges. In recent years, increasing attention has been given to the recycling and utilization of phosphogypsum in construction applications such as gypsum boards, wall materials, aggregates, and cement additives.
The successful system commissioning confirmed the operational stability of the production process as well as the reliability of the finished products. During the testing phase, the production line demonstrated stable equipment coordination, continuous material flow, and effective process control across multiple manufacturing stages. These results provide a solid foundation for future large-scale industrial operation.
The project also reflects broader industry trends toward resource recycling, industrial waste reduction, and sustainable construction material manufacturing. By integrating phosphogypsum utilization with industrial solid waste processing, the industrial park contributes to improving resource efficiency and reducing environmental pressure associated with industrial byproducts.
In addition to environmental benefits, the project is expected to support local industrial development by expanding the supply of recycled building materials and promoting the adoption of green manufacturing technologies. The development of phosphogypsum-based products may also help reduce dependence on traditional raw materials in certain construction applications.
As global industries continue to focus on sustainability and circular manufacturing systems, projects involving phosphogypsum recycling are expected to play an increasingly important role in the building materials sector. The successful commissioning of the Anning industrial park Phase II system represents another step toward the industrial-scale utilization of phosphogypsum and the advancement of green building material technologies in China.
