Nowadays the awareness of the environmental problem highlights a number of priorities that national and international governments must take in consideration in their future policy-making and namely with regards to the depletion of the natural resources of raw materials and the energy consumption by reducing the amount of waste produced as well as by fostering recycling. This is just one aspect of an increased sensitivity towards the impact of human activities on the environment.
In this perspective the concept of sustainable growth became more and more important, an economic development capable of satisfying the present needs without compromising the possibility for future generations to meet their own requirements. This means that it’s necessary and mandatory to gauge consumptions and behaviors of human beings with the planet’s sustainability, through a careful management of natural resources (especially those already at stake), in order to prevent waste and depletion.
Aluminum recycling is notably convenient, allowing consistent energy and economic savings. Besides allowing savings up to 95% of the energy required for its production starting from the raw material, its popular use and high intrinsic value make profitable complex and sophisticated recovery technologies because they can work on any obsolete and worn out products. Therefore, from this point of view, aluminum derived from scraps (or recycled), must not be considered a waste but a relevant economic resource for a country’s economy. In Europe, Italy is a leader in the production of secondary (or better to say, recycled) aluminum, and holds a position of absolute excellence in the world scenario, which is amazing if we think that Italy has almost no mines of raw material (bauxite) for the production of primary aluminum.
From an environmental point of view, therefore, aluminum recycling gives a significant contribution to sustainable development, as, thanks to recycling activities, aluminum is not consumed, but used for the whole service life of a product.
