| Research Abstract |
Phosphorus is an important strategic resource for agricultural food production and the chemical industry. Considering the limited supplies of phosphorus resources, it is important to evaluate the quantity and availability of currently untapped phosphorus resources. Thus, we developed the Integrated Phosphorus Cycle Input Output (IPCIO) model to estimate the phosphorus requirements for economic activities and to evaluate the recycling effects. We found that automotive industry requires yellow phosphorus, which comprises about half of all required phosphorus in its supply chain, while the production bases of yellow phosphorus in Asia are located only in China and Vietnam, with practically the whole supply dependent on these two countries. It was suggested that since delays in the supply of yellow phosphorus present significant effects throughout the supply chain.
