According to Sinochem New Network, the 19th Gypsum Industry Technology Exchange Conference was held recently in Yidu, Hubei. Industry representatives focused on phosphogypsum treatment technologies, engineering applications, and market prospects, seeking new paths for the harmless, high-value, high-quality, and large-scale development of industrial by-product gypsum, in order to promote the optimization and upgrading of the industry as well as the coordinated development of its value chain. Cui Rongzheng, head of the Phosphatic Fertilizers Department at the China Phosphorus Fertilizer Industry Association, said that the national production of phosphogypsum in 2024 reached 86 million tons, and it is expected that this annual production level will remain above 80 million tons in the future. He suggested that during the 15th Five-Year Plan period, the comprehensive utilization of phosphogypsum should focus on four aspects. First, strengthen top-level design and improve the policy framework ； Second, build an industrial ecosystem to overcome technical bottlenecks ； Third is innovation-driven transformation to enhance competitiveness ； Fourth, deepen public awareness and promote co-governance and shared benefits. **Zeng Yuping, former chief statistician of the Bureau of Statistics, pointed out that the gypsum industry is an important pillar for building \"waste-free cities\" and advancing a circular economy; it is necessary to rely on innovation to overcome barriers to achieving higher value-added products and to improve the standard system ； Strengthen the market orientation and facilitate precise matching between supply and demand in the industrial chain ； Deepen collaborative efforts to foster an ecosystem for integrated industrial development ； Focus on green development, and improve the environmental protection standards across the entire industrial chain as well as efforts in talent cultivation. As the largest phosphate mine area in the Yangtze River basin, Yichang has phosphate reserves of 4.334 billion tons, and the comprehensive management of phosphogypsum is a key task. Li Xiaojun, vice mayor of Yichang and secretary of the Party Working Committee of Yichang High-Tech Zone, said that the city is about to issue the \"Implementation Opinions on Supporting the Comprehensive Utilization of phosphogypsum,\" with the goal of achieving a dynamic balance between the amount of phosphogypsum generated and the amount that is comprehensively utilized by 2026. Xia Minghai, Secretary of the Yidu Municipal Party Committee, explained that the city invested 1.9 billion yuan in building a centralized storage facility for phosphogypsum, with a total capacity of 67.56 million cubic meters, which is sufficient to meet the storage needs of Yidu’s phosphorus chemical enterprises over the next 18 to 20 years. Peng Jinxin, former director of the Policy and Regulation Department and the Ecological Protection Department of the Ministry of Environmental Protection, put forward suggestions such as promoting the sustainable and diversified use of phosphogypsum, improving supervision to facilitate higher-quality utilization of phosphogypsum, and exploring new scenarios for innovative use of phosphogypsum resources. The gypsum industry has achieved some success in high-value utilization. Xu Luoyi, vice president of the China Building Materials Federation and chairman of the Gypsum Building Materials Branch, explained that type II anhydrous gypsum developed using phosphogypsum in this industry can be used in the field of polymer fillers, for manufacturing gypsum-based municipal pipes, as well as pipes for power and communication applications. Hubei Yihua Group has successively overcome various key technologies such as the deep purification of phosphogypsum and the production of high-purity, high-whiteness Type II anhydrous gypsum, filling gaps in domestic large-scale production technologies. It has also built and put into operation multiple units for the purification and harmless treatment of phosphogypsum, as well as facilities for manufacturing phosphogypsum products, with an annual processing capacity of nearly 3.5 million tons.
