The Austrian silver cycle: A material flow analysis

Silver (Ag) is a precious metal of increasing importance. Besides its classical use as a valuable, it is applied in an increasing number of industrial products due to its advantageous chemical properties. As silver is considered a non-renewable resource, it is becoming more and more relevant for individual countries to gain a better understanding of their domestic silver material flows. In our study, a material flow analysis (MFA) of silver in Austria for the period 2012 was carried out, the results of which reveal the major silver flows in the country as well as the imports and exports outside the country. As there is no extraction of silver ore in Austria, the country is depending on silver imports and recycling. Furthermore, the role of the silver coin production that is of considerable importance in Austria is highlighted. The results may help, on a policy level, to determine silver use indicators and support the development of strategies for resource, waste and environmental management of silver. On a modeling level, the results may function as an example for future silver MFA studies in different countries.
