The life cycle of aluminium

A crucial step in your green building project is the choice of sustainable materials. Luckily, a life cycle analysis (LCA) can help you choose the most responsible solution. How does this method work? And what does it tell about the recyclability of aluminium? Find out here.

A life cycle analysis evaluates the environmental impact of products throughout their entire life, from raw material to final disposal – or what we call “end of life”. In the current building industry, recyclability has become a very important subject as companies start evaluating the life cycle of their core materials. Here we focus on the main component of our window, door, and curtain wall solutions: aluminium.

Analyse du cycle de vie de l'aluminium

Les données mènent à la connaissance. C'est pourquoi AluEco, une fondation qui promeut la durabilité et la recyclabilité dans le secteur de la construction, a commandé une étude sur les propriétés environnementales des éléments de façade en aluminium. L'étude est basée sur la méthode ACV et a été réalisée en coopération avec l'Association de l'industrie des fenêtres et façades métalliques (VMRG) et l'Association du traitement de surface industriel des Pays-Bas (ION).

AluEco et ses partenaires ont réalisé l'analyse du cycle de vie des profilés en aluminium pour le traitement de surface par poudrage et par anodisation. Quel est le résultat ? Les éléments de façade en aluminium ont une durée de vie d'au moins 75 ans et un minimum de 95 % peut être récupéré par recyclage. En théorie, cela signifie que les éléments de façade peuvent avoir une durée de vie totale de 1 500 ans !

Aluminium façades have a lifetime of 75 years and are at least 95% recyclable.

What does this mean for building professionals? For example, this validated report can be used to determine a rating, which is an environmental certification procedure for buildings. Moreover, architects, building advisors or fabricators can make calculations and design solutions with the correct environmental properties of the aluminium façade elements in mind.

Endless recyclability

In addition to its aesthetic, extremely durable and energy-efficient properties, aluminium offers excellent results in terms of sustainability and recyclability as well. And unlike many other building materials, aluminium does not lose its characteristics in the recycling process. Enjoy unrivalled quality and performance at all times

At Reynaers Aluminium, we are constantly investigating innovative ways to improve the recyclability of our products – without loss of quality. For instance, by recycling as much aluminium scrap as possible, we can close the aluminium circle more easily and create new window and door profiles from recycled materials, forever. It is circularity at its finest.
