The IMA Study on the Life Cycle Assessment (LCA) of Magnesium

Horst E. Friedrich; Simone Ehrenberger

Magnesium shows considerable potentials as lightweight material for weight sensitive applications. To assess the potential environmental benefits of magnesium in transport applications, the International Magnesium Association (IMA) initiated a study on the life cycle assessment (LCA) of magnesium.

Recycling, Life-Cycle-Assessment und Rohstoffverfügbarkeit

Simone Ehrenberger; Sven Knöfel; Stephan Schmid; Eckhard Schüler-Hainsch

Leichtbauwerkstoffe sind im Automobilbau seit geraumer Zeit im Einsatz. Im Zuge der verstarkten Bemuhungen, leichte und somit potenziell sparsamere Fahrzeuge zu entwickeln, wird verstarkt uber die Vor- und Nachteile einzelner Leichtbaumaterialien diskutiert. Die Masse eines Fahrzeugs ist ein wichtiger Hebel, Kraftstoffeinsparungen zu erzielen. Ein niedrigerer Kraftstoffverbrauch fuhrt nicht nur zu einer Schonung fossiler Ressourcen, sondern ist auch mit einer Verminderung der Emissionen aus Verbrennungsprozessen verbunden. Die im Automobilleichtbau verwendeten Werkstoffe konnen sich aus okologischer Sicht in ihrer Herstellung und Verwertung masgeblich von herkommlichen Materialien unterscheiden. In der Regel sind Leichtbaumaterialien mit einem hoheren Produktionsaufwand im Vergleich zu konventionellen Materialien wie Stahl verbunden, was zu einer Verschiebung von Emissionen aus der Nutzungsphase in die Herstellungsphase eines Bauteils fuhrt. Um Aussagen uber den okologischen Vorteil eines Leichtbauteils treffen zu konnen, reicht es daher nicht aus, nur die Kraftstoffeinsparung in der Nutzungsphase eines Fahrzeugs zu betrachten. Vielmehr muss eine ganzheitliche Betrachtung uber den gesamten Lebensweg eines Fahrzeugs und der fur Herstellung und Betrieb erforderlichen Vorprozesse erfolgen.

Electric vehicles have the potential to substitute for conventional vehicles and to contribute to the sustainable development of the transportation sector worldwide, e.g. reduction of greenhouse gas and particle emissions. There is an international consensus that the improvement of the sustainability of electric vehicles can only be analysed on the basis of life cycle assessment (LCA) including the production, operation and the end of life of the vehicles. Based on LCA activities in the 17 member countries, the International Energy Agency (IEA) Implementing Agreement on Hybrid and Electric Vehicles (IA-HEV) works in a Task on the LCA of electric vehicles. In this Task 19 “Life Cycle Assessment of Electric Vehicles - From raw material resources to waste management of vehicles with an electric drivetrain” the key issues of applying LCA to EVs&HEVs are identified and applied in various case studies. The following seven categories of key issues were identified, analysed and applied in “best practice” applications: 1) General issues, 2) Life cycle modelling, 3) Vehicle cycle (production - use - end of life), 4) Fuel cycle (electricity production), 5) Inventory analyses, 6) Impact assessment and 7) Reference system. For these seven key issues the main relevant factors were identified, reviewed and verified in international “best practice” applications.
