"Aluminum is a stable, strong, albeit lightweight and durable material that is the cornerstone of many industries. So, it's not surprising that the demand for aluminum, especially in its recycled form, is steadily increasing. Leading the way is the automotive industry, which is increasingly turning to recycled materials in the production of new cars to meet regulatory requirements," explains Frank van de Winkel, Market Strategy Manager at TOMRA Recycling Sorting.
With ever more efforts to increase the use of
recycled content in automotive production and other industries, the separation
of aluminum scrap according to alloy classes is taking on a decisive role. Aluminum
alloys consist of different elements, such as magnesium, zinc, copper, or
silicon. These additional elements define the specific properties of the
aluminum alloy. Alloy classes 5000 and 6000 are particularly in demand in the
automotive industry. While the production scrap is collected, it is a mixture
of numerous elements which proves challenging in the recycling process. Due to
the high-quality demands, the requirements to use more recycled material, and
the industry’s decarbonization goals, automotive manufacturers are looking to
increase the use of aluminum scrap. To recycle the scrap generated in
production, it must first be sorted by alloy type. This requires innovative
solutions which the consortium is testing.
