Klaus Schmitz is the Vice President of Sales for Thermoprocessing Plants for Aluminium and Copper at OTTO JUNKER GmbH. With deep expertise in thermal processing technologies, he plays a key role in driving innovation and sustainability within the aluminium industry. In Advanced Industrial Technologies in the Aluminium Industry (Part II), Mr. Schmitz shares valuable insights on electrification, digitalisation and carbon reduction strategies. His leadership continues to support global advancements in energy-efficient furnace solutions. Known for his strategic foresight, he advocates for practical collaboration between technology providers and industry operators.

AL Circle: How successful have you been over the past year in transforming aluminium production and processing efficiency in Europe? What key insights have emerged from this journey?

Klaus Schmitz: In recent years, aluminium production in Europe has faced significant challenges due to high energy costs, extensive regulation, and policy frameworks that are not always industry-friendly. As a result, only limited investments have been made in the European Union (EU) market. OTTO JUNKER has developed numerous technological solutions aligned with the EU Green Deal targets. However, the current environment makes it difficult for many European customers to compete globally – especially given the economic challenges associated with implementing green technologies under current market conditions. Their focus often remains on the domestic market. Nevertheless, we believe the time is approaching when our “ready-toimplement” technologies will find broader application – helping companies balance sustainability goals with operational efficiency. 

AL Circle: Have you observed a growing openness in the market toward adopting technology and digitalisation in the aluminium processing?

Klaus Schmitz: As already mentioned, many of our new technologies have been developed to be ready for immediate use. In Europe, we observe a high level of interest and openness toward digitalisation – however, financial constraints often limit the ability to invest. Outside of Europe, customers tend to prioritise reliability and proven technologies over new, digital approaches. At the same time, the momentum around digitalisation has slowed significantly in many regions due to persistent cybersecurity concerns and the lack of effective protection against digital crime. One of the few exceptions remains China, where digital technologies continue to be actively developed and implemented.

AL Circle: How do you plan to further reduce carbon emissions in the aluminium processing industry with your innovation?

Klaus Schmitz: At the beginning of 2025, we installed the first electrically heated billet heater of the EcoJet type at an extrusion plant. The predicted thermal efficiency of over 93 per cent was confirmed during the initial months of operation. The use of electricity combined with high thermal efficiency results in a significant reduction in carbon emissions. For most of our aluminium furnaces, OTTO JUNKER offers electrical heating as an option. This provides the opportunity to reduce carbon emissions to zero – when renewable energy is used and for those specific furnace types where this option was not previously available – such as the aforementioned billet heaters – OTTO JUNKER has developed new solutions in recent years.
