Comparative analysis of the resource efficiency of primary and secondary raw material production - Economic indicators and the energy expenditure as a central evaluation indicator - the raw material-energy-nexus

In the project three topics will be processed. The first complex deals with the importance of the primary raw material in relation to the secondary raw material economy in Baden-Württemberg.

The second complex deals with the regionalization of current national and international approaches for economic indicators to measure resource efficiency.

The third part proposes a comprehensive approach for assessing the ecological and economic costs of primary and secondary production of raw materials. The focus is on the energy expenditure associated with the extraction or recycling of raw materials ( "Nexus"). The approach deals, e.g. With the energy expenditure with decreasing ore content in primary production or with increasing dissipation of valuable substances during recycling. An energetic indicator is used, which includes both the primary and secondary production for different raw materials as well as the substitution of raw materials among each other. This part is handled by INEC.
