The developed methodology is applied to platinum-containing cytostatic drugs and automotive catalytic converters. Methods The study is methodically based on an analysis of resource specific factors like exploration rates reserves-to-production ratio and regional distribution of exploration areas as well as on the investigation of product functional depending factors like recycling rates dissipation rates bio-diversity and toxicity. Taking into account that economic and ecological risks may occur at any stage of the supply consumption and dissipation processes the whole life cycles of the two analyzed products cytostatic drugs and automotive catalytic converters are considered. As an approach to reduce potential economic and ecological risks the study is especially focused on recycling strategies. Background In order to get a better understanding of platinum as an essential resource for the development of our society the history and the cultural impact of the term resource are introduced. Results Discussion The availability of platinum is crucial for several products of our modern society. Areas of application are e.g. jewellery automotive catalytic converters investments coins bars computers mobile devices .
