Aluminium and sustainability
Aluminium and sustainability: what do these words have in common? Why is aluminium called the green metal? Some useful information.
Aluminum is the most abundant metallic element in Earth’s crust and bauxite ore is its main source. This material is:
- particularly light: about 1/3 that of copper or steel
- resistant to corrosion: when it corrodes a thin layer of aluminum oxide forms over the surface of the metal, acting as a protective barrier against water and chemical substances
- easily workable: it can be cast, or shaped by various means ranging
- a good heat and electricity conductor
- 100% recyclable
Aluminum: a sustainable and recyclable material
In particular, the last characteristic is essential to understand the connection between aluminium and sustainability. This material is 100% recyclable and can be recycled time and time again without loss of properties. More than this, aluminium takes up to 95 percent less energy to recycle it than to produce primary aluminum avoiding CO2 emissions. So, it’s clear that aluminum recycling benefits present and future generations by conserving energy and other natural resources.
