Recently, the attention of economists, politicians and researchers has been focussed not only on the widely discussed subject of exhaustible energy resources. Rather, the scarcity of metallic and mineral raw materials alike has increasingly received attention. On principle, the demand to increase resource and material efficiency may be met at all levels of the value chain. A systematic analysis will identify possible approaches at the stages of mining of raw materials and the production of primary products, whose potential to save materials is, however, limited. The same applies to the levels of the production of goods, the use of goods and that of waste management. These latter stages of the value chain have a far greater impact. However, concrete measures such as material-efficient design, optimized production processes, leasing models or urban mining require a harmonized and integrated policy, if possible on an international level, and noticeable changes in the behaviour of users. |
