Access to natural resources is
increasingly more difficult and more costly, partly due to their economic
significance and to continuous increase
of their global consumption in the recent years. In the case of phosphorus (P),
which is a critical raw material, geological distribution of its primary
nonrenewable source (phosphate rock) is concentrated in particular regions
leading to high supply risk of this raw material. In Europe (EU-28), where
phosphate rock reserves are scarce, import of phosphorus has been the main
source of supply. It means that Europe relies highly on the foreign exporters.
From decision makers’ perspective,
recycling of phosphorus was taken into account as one of possible solutions to decrease the dependence
on imports and extraction of reserves. The question, however, is to what extent
the recycling of phosphorus helps reducing
the reliance on typical supply resources? Hence, the main objective of this
paper is to quantify the dynamic flow of phosphorus and show potential benefits of its recycling in Europe. This
article presents a system dynamics
model for representation of the element P flow and
helps to quantify to what
extent the recycled phosphorus
could mitigate its criticality. Analysis of the results support previous studies indicating the high
reliance of EU on P imports, estimating around 96% as the reliance percentage
on imports. The results imply that improving P
recycling has the potential to decrease the level of P imports to a
certain extent, which may achieve at 79%.
