On July 5th, the 5th National Technical Exchange Conference on Phosphorus Resource Development and Utilization (Qiangsheng Forum) was grandly held in Yichang, Hubei Province. As an innovative pioneer in the field of phosphogypsum resource utilization, Mr. Zhan Zhiyong, Chairman of Handern Machinery, was invited to attend and deliver a keynote report entitled *Project of High-Fill Phosphogypsum Environmental Protection and Moisture-Proof Packaging*. The "high-performance phosphogypsum packaging box" showcased on site won high praise from participating experts and enterprise representatives for its environmental friendliness and technological breakthroughs, marking that the high-value application of phosphogypsum solid waste has entered a new stage of marketization.

Breaking Through Tradition: Reshaping the Packaging Industry Ecosystem with Solid Waste 

Phosphogypsum is the main solid waste in phosphorus chemical production, and long-term stockpiling can easily cause environmental pollution. The high-filling phosphogypsum environmental protection and moisture-proof packaging material innovatively developed by Handern Machinery  achieves a phosphogypsum addition ratio of over 70% through exclusive modification technology. It also overcomes key bottlenecks such as strength and moisture resistance, and its performance is significantly better than that of traditional cartons: 

 - **Environmental Advantages**: Reduces wood consumption, with 1 ton of phosphogypsum replacing 1.3 tons of pulp. 

 - **Performance Upgrade**: Features waterproof and moisture-proof properties as well as compressive strength, suitable for high-demand scenarios such as cold chain and electronic equipment.

 - **Cost Competitiveness**: The raw material cost is lower than that of traditional packaging, with outstanding potential for large-scale production. 

 Innovation-Driven, Green Empowerment 

 Handern Machinery has always been committed to the comprehensive utilization of phosphogypsum solid waste and the research and development of environmental protection materials. The high-filling phosphogypsum environmental protection and moisture-proof packaging material shared this time has increased the proportion of phosphogypsum to the industry-leading level through original technology. It has the characteristics of low cost, high strength, moisture resistance and weather resistance, and can be widely used in building materials, logistics packaging and other fields, providing a new solution for large-scale consumption of phosphogypsum and low-carbon circular economy. The chairman elaborated on the technical breakthroughs, industrialization process and market application cases in his speech, which received a warm response on site.

Future Layout: Accelerating Technology Industrialization 

 Mr. Zhan Zhiyong, Chairman of Handern Machinery, stated that the company has jointly established the Hubei Provincial Engineering Research Center for Biomedical and Protective Materials with Huazhong University of Science and Technology, and the Industry-University-Research Production Demonstration Base for High-Efficiency and Energy-Saving Plastic Extrusion Molding Equipment with South China University of Technology. The next step is to promote the implementation of the demonstration production line of phosphogypsum packaging boxes and form a closed loop of "waste residue material application" with leading phosphate fertilizer enterprises. At the policy level, the project has applied for the Hubei provincial green manufacturing special project and is expected to be included in the national resource comprehensive utilization promotion catalog. 

Win-Win Cooperation to Build a Green Industrial Chain 

Handern Machinery sincerely invites upstream and downstream partners and industry colleagues to jointly explore the broad prospects of phosphogypsum resource utilization, and inject new momentum into environmental protection and sustainable development!
