Recently, the Department of Science and Technology of the Ministry of Industry and Information Technology (MIIT) officially announced the First List of Advanced Applicable Technologies. The independently developed "Integrated Technology for Phosphate Gypsum Upgrading via Multi-Stage Counter-Current Water Washing and Modification" by China Wuhuan Engineering Co., Ltd. has been successfully included in the list.
In November 2024, the General Office of MIIT issued the Notice on Launching the Selection of Advanced Applicable Technologies (First Batch), aiming to accelerate the promotion and application of advanced technologies and drive the manufacturing industry toward high-end, intelligent, and green development. The selection followed strict procedures, including voluntary application, formal review, and expert evaluation.
It is reported that China Wuhuan Engineering developed this technology to address critical industry challenges such as environmental pollution and extensive land occupation by phosphate gypsum. The technology achieves efficient, harmless treatment of phosphate gypsum, eliminates potential ecological contamination risks, and innovatively transforms waste phosphate gypsum into reusable resources.
Currently, China Wuhuan Engineering has applied the technology across multiple engineering projects with remarkable results. It significantly conserves natural gypsum resources, reduces waste, minimizes land usage for phosphate gypsum stockpiling, and pioneers green, low-carbon transformation in the industry. The company has established over 10 phosphate gypsum harmless treatment production lines, with an annual processing capacity of 20.75 million metric tons. This advancement strongly propels China’s phosphorus chemical industry to world-leading levels in green development.
