    Messung von Ressourceneffizienz mit der ESSENZ-Methode

    Get PDF
    Eine belastbare Methode zu entwickeln, um den Ressourceneinsatz zu bewerten, ist das Ziel dieses Buches. Notwendig ist dies, da das starke Wirtschaftswachstum der letzten Jahrzehnte zu einer intensiven Beanspruchung natürlicher Ressourcen geführt hat. Mit ihrer steigenden Nutzung gehen auch zusätzliche Belastungen der Umwelt sowie Restriktionen der Verfügbarkeit von Ressourcen einher. Aus diesen Gründen ist ein effizienter Einsatz von Ressourcen als wichtiger Beitrag zu einer nachhaltigen Entwicklung erforderlich. Die ESSENZ-Methode (Integrierte Methode zur ganzheitlichen Berechnung/Messung von Ressourceneffizienz) wurde in einer Kooperation der Technischen Universität Berlin mit den Industriepartnern Daimler AG, Deutsches Kupferinstitut Berufsverband e. V., Evonik Industries AG, Siemens AG, ThyssenKrupp Steel Europe AG und Wissenschaftlicher Gerätebau Dr. Ing. Herbert Knauer GmbH entwickelt. Sie unterstützt die umfassende Messung und Bewertung von Ressourceneffizienz innerhalb der vier Dimensionen „Verfügbarkeit“, „Gesellschaftliche Akzeptanz“, „Umweltauswirkungen“ und „Nutzen“. Um diese vier Dimensionen wissenschaftlich abzubilden, werden 21 anwendbare Indikatoren entwickelt und vorgestellt. Die ESSENZ-Methode kann sowohl für die Analyse und Optimierung eines einzelnen Produktes als auch für den Vergleich mehrerer Produktalternativen verwendet werden. Ihre Anwendbarkeit ist für Metalle und fossile Rohstoffe bereits erprobt.BMBF, 033R094A-F, r³ - Strategische Metalle, Verbundvorhaben: Integrierte Methode zur ganzheitlichen Berechnung/Messung von Ressourceneffizienz - ESSEN

    Integrated method to assess resource efficiency – ESSENZ

    With increasing demand of abiotic resources also the pollution of natural resources like water and soil has risen in the last decades due to global industrial and technological development. Thus, enhancing resource efficiency is a key goal of national and international strategies. For a comprehensive assessment of all related impacts of resource extraction and use all three sustainability dimensions have to be taken into account: economic, environmental and social aspects. Furthermore, to avoid burden shifting life cycle based methods should be applied. As companies need operational tools and approaches, a comprehensive method has been developed to measure resource efficiency of products, processes and services in the context of sustainable development (ESSENZ). Overall 21 categories are established to measure impacts on the environment, physical and socio-economic availability of the used resources as well as their societal acceptance. For the categories socio-economic availability and societal acceptance new approaches are developed and characterization factors are provided for a portfolio of 36 metals and four fossil raw materials. The introduced approach has been tested on several case studies, demonstrating that it enhances the applicability of resource efficiency to assess product systems significantly by providing an overall framework that can be adopted across sectors, using indicators and methods which are applicable and can be integrated into existing life cycle assessment based schemes.BMBF, 033R094A-F, rÂł - Strategische Metalle, Verbundvorhaben: Integrierte Methode zur ganzheitlichen Berechnung/Messung von Ressourceneffizienz - ESSEN

    Comparative Life Cycle Assessment of NdFeB Permanent Magnet Production from Different Rare Earth Deposits

    Neodymium, praseodymium, and dysprosium are rare earth elements often used in high performance magnets. Environmental impacts during the production of a 1 kg of neodymium iron boron (NdFeB) magnet from three major deposits are quantified using life cycle assessment (LCA). The scope of the assessment includes the largest rare earth oxide (REO) production in Bayan Obo (China), the second largest at a mine in Mount Weld (Australia), and a third mine in Mountain Pass (U.S.A.) that closed production in 2015. Consecutively, impacts from metal refining and final magnet production are added. Environmental impacts along the magnet production life cycle are dominated by the production of rare earth components (50–99.9%). Using REOs from the American mine shows the best overall environmental performance due to improved handling of chemicals. The biggest differences from the worst Chinese pathway can be found in freshwater and terrestrial ecotoxicity, acidification, freshwater eutrophication, particulate matter, and human toxicity. The smallest differences are observed for climate change, resource depletion, and marine eutrophication. For the first time, an LCA for the three largest rare earth producers was performed under the same frame of conditions and methodological assumptions. This approach is a step toward getting a consistent picture of environmental impacts
