Kömmerling Aluminium

Recycled aluminium.

Across our entire system range.

We use recycled aluminium across our entire aluminium system range. Our aluminium suppliers are required to meet our recycled-content specifications.

 

Recycled aluminium is part of every Kömmerling aluminium system. Producing primary aluminium is energy-intensive. Remelting aluminium scrap uses less energy than producing primary aluminium. We use recycled aluminium across our entire system range and set recycled-content requirements for our aluminium suppliers. Our recycling loop for aluminium production scrap is already in operation.

 

Aluminium can be recycled repeatedly.
Collected aluminium scrap is sorted by alloy and remelted for use in new products. The recycled metal is specified for the requirements of its next application. Recycled aluminium in every system. Production scrap returned for recycling.
Slim profiles. Recycled aluminium in every system. Production scrap returned for recycling.
