Life Cycle Comparison of Aluminum and Magnesium Products in Front-End Auto Parts
The study compares the use of steel, aluminum, and magnesium frames from a cradle-to-grave approach, meticulously analyzing every aspect of the extraction, manufacturing, and disposal processes, even the GHG from the distance of the recycled materials to their new destination. The impact of the different metals is directly related to the weight it adds to the car meaning heavy steel leads to more energy required to move to vehicle. The magnesium front end reduces the weight of the steel car by 45 kg which leads to a reduction of 507 liters of petrol over the life of the car. Aluminum weight reduction leads to a 289-liter reduction in fuel.
However, the full LCA must be completed, and in the end even though magnesium performs well, the study finds that the production of highly reactive magnesium is a energy, GHG-intensive process. Therefore, in the current state of technology and within the lifetime of the vehicle, aluminum has a better performance than magnesium because magnesium requires coal in its production. Even though the aluminum design is a solid contender in terms of energy and GHG emissions for current manufacturing, through further investment in the relatively immature magnesium process it is likely that a substantial reduction in emissions could be achieved through a better primary magnesium production technology accentuated by enhanced recycling capability. This would mean that with better technology, the magnesium front end will have the smallest impact on the environment.
To illustrate how thorough this study was, the authors also organize a thorough sensitivity analysis to verify the implications of the LCA, comparing their techniques and assumptions to the range of possible scientific error.
This LCA study is especially important because of the quantity of toxic fumes, GHG-emissions, and mineral waste that cars produce. If improvements such as the lighter front ends can be implemented in all cars around the world, their potential environmental impact is enormous.
