Low-CO₂ aluminium
Aluminium is 100% recyclable, but its production is very energy-intensive. It is therefore important that it is produced using renewable energy sources and recycled after use. When selecting our suppliers, we pay attention to the use of climate-friendly raw materials and renewable energies. As a result of this and the continuous improvement of our internal processes and procedures, the manufacturers we select are able to offer aluminium that is produced with the lowest possible emissions and thus demonstrably leaves a much smaller ecological footprint than the market average.
On average, 16.7 kg of CO₂ are emitted per kg of aluminium worldwide. The production of the aluminium we purchase generates an average of less than 4 kg of CO₂ per kg of aluminium. Our suppliers focus on reducing the consumption of materials, water and energy as well as minimising waste and hazardous substances. Our suppliers not only recycle their own waste resulting from the production process, but also process more than 50% of existing aluminium, including completely worn-out products, in the production of new aluminium. Here, too, the unusable residual materials or waste products are used for the production of new aluminium profiles - a flexible cycle. When selecting our upstream suppliers, another important criterion is proximity to our plants, so that transport routes are minimised as far as possible.
Good to know
Few materials are as easy to recycle as aluminium. It takes only 5% of the energy needed to produce the original primary metal to recycle it. In fact, 75% of all aluminium ever produced is still in use.
Aluminium is a durable material. This means that it can be recycled multiple times without deteriorating; the basic properties remain unchanged.
Sustainable materials
For our sound absorbers, we mainly use natural wool from sustainable sources, which, unlike plastic foam, is 100% biodegradable.
