Raw phosphorus is obtained from mining phosphate rock. These mines are for the largest part located in Morocco, the US and China. In Europe hardly any raw phosphorus is available, except for a very small quantity in Finland.
Therefore, virtually all phosphorus in Europe has to come from outside Europe. Due to increasing welfare in Africa, Latin America and Asia and an ever increasing world population, the demand for phosphorus is growing.
The dependency of Europe on raw phosphorus from outside Europe endangers our access and threatens our future food security.
