—Phosphorous is an essential natural resource that is projected to run out rapidly. Environmental pollution and resource scarcity pressures require the development of a phosphorous management system in China. One of the fundamental steps to achieve this is to understand the way that phosphorous flows throughout the country. It helps to find out the current phosphorous utilization conditions and provide reliable evidence for both technology and strategy development. Based on these reasons, substance flow analysis of phosphorous was thus conducted to investigate phosphorous flow types and quantify stream values for China. The result indicates that phosphate rock resources in china will run out within 35 years at the current consumption rate, which indicates the urgency of phosphorous recovery. The substance flow analysis will also provide a guide for efficient recovery schemes design in future work. Overall, with a phosphorous crisis approaching in China, it is suggested that work be carried out into phosphorous recovery techniques and management policies.
