Insight: Origin of the extrusion billets
The raw material for our profiles is cast aluminium extrusion billets.
The conditions under which these are produced have a direct influence on
the carbon footprint. If, for example, the electricity required for the
electrolysis process is generated by coal-fired power stations, as is
the case in China, for instance, the production of 1 kg of aluminium
generates around 20 kg of greenhouse gas emissions*.
At least 75% of the extrusion billets we use are produced in Europe using renewable energy, primarily from hydropower and thermal energy sources. This enables us to achieve an average CO₂ value of less than 5 kg CO₂ equivalent per kg of aluminium. Compared with the global average of around 17 kg CO₂ equivalent per kg of aluminium* (cradle-to-gate), this represents a significant reduction in emissions.
In this way, we are laying the foundations for aluminium solutions that are not only technically impressive but also make a measurable contribution to reducing emissions.
