Primary production of aluminium requires a large amount of energy, Against this background, it plays a very important role which environmental choices are made in the production chain in order to reduce the impact on the environment.
Aluminum is plastic moldable. It can be alloyed to the same strength as many structural steels. The metal is lightweight and can be welded, soldered and glued. In primary production, large amounts of energy are needed. However, aluminum can easily be recycled with retained properties for low energy input. There is a well-functioning trade in aluminum scrap. The collection rate is high. For example, 90 percent of all aluminum is recycled in cars.
Low weight, long service life and minimal maintenance need make aluminum an environmentally good choice of material if the product life cycle is taken into account.
