It was a fantastic opportunity to connect with industry professionals and share our vision at QuantoLux GmbH for the future of slag analysis. --- **From Human Judgement to Data Precision** In my presentation titled **"The End of Visual Slag Evaluation: Tomorrow’s Process Management Based on Analytical Data"**, I talked about the limits of traditional visual slag evaluation. For many years, operators have relied on experience and visual cues—but this approach can be inconsistent, especially in fast-moving industrial environments. I explained how **Optical Emission Spectroscopy (OES)** is changing the game. With OES, we can: - Detect key elements like magnesium, aluminum, and silicon in real time—even in complex oxidic slags - Achieve much higher precision and repeatability than with subjective visual methods ![laser OES slag analysis presentation by Alexander Schlemminger](https://14563635.fs1.hubspotusercontent-na1.net/hub/14563635/hubfs/WhatsApp%20Bild%202025-07-03%20um%2015.35.53_d2023229.jpg?width=1200&length=1200&name=WhatsApp%20Bild%202025-07-03%20um%2015.35.53_d2023229.jpg) laser OES slag analysis presentation by Alexander Schlemminger ![laser OES slag analysis presentation by Alexander Schlemminger](https://14563635.fs1.hubspotusercontent-na1.net/hub/14563635/hubfs/WhatsApp%20Bild%202025-07-03%20um%2015.35.53_c6e17485.jpg?width=1200&length=1200&name=WhatsApp%20Bild%202025-07-03%20um%2015.35.53_c6e17485.jpg) laser OES slag analysis presentation by Alexander Schlemminger ![EMC 2025 Speaker Award](https://14563635.fs1.hubspotusercontent-na1.net/hub/14563635/hubfs/WhatsApp%20Bild%202025-07-03%20um%2015.49.28_e10af620-1.jpg?width=1200&length=1200&name=WhatsApp%20Bild%202025-07-03%20um%2015.49.28_e10af620-1.jpg) EMC 2025 Speaker Award --- **Improving Process Control and Sustainability** I also showed how switching to OES enables real-time, in-situ control of the process. That means no more waiting until the end of a batch to evaluate results—we support immediate reactions, reducing energy use, processing time, and costs. What excites me most is how this shift supports **more sustainable production**. With better data, we can use secondary raw materials more effectively and reduce waste—making our industry not only smarter but also greener. --- **The Conference Atmosphere** EMC 2025 was a vibrant event, full of inspiring talks and engaging discussions. With over 120 presentations from more than 320 authors, the program covered essential topics like **sustainability**, **decarbonization**, **battery recycling**, and **digitalization**. The venue at Privathotel Lindtner in Hamburg-Heimfeld provided the perfect setting. I enjoyed the warm welcome evening, the dinner at Rheinischer Hafen, and a relaxing boat tour through Hamburg Harbour. These moments created space for informal conversations and new collaborations. ![Amazing talks during the coffee break](https://14563635.fs1.hubspotusercontent-na1.net/hub/14563635/hubfs/WhatsApp%20Bild%202025-06-24%20um%2012.54.12_0991c1df.jpg?width=1200&length=1200&name=WhatsApp%20Bild%202025-06-24%20um%2012.54.12_0991c1df.jpg) Amazing talks during the coffee break at EMC 2025 --- **Our Role at QuantoLux** At the conference, I represented QuantoLux and shared how we are helping to shape the future of process control. Our OES platform delivers real-time slag composition analysis, giving operators clear, actionable data—moving us beyond visual inspection into a fully **data-driven approach**. I had great discussions with industry leaders, researchers, and equipment manufacturers. Many were excited about the potential of OES in their own operations, confirming what I already believe: **the industry is ready for this change**. --- **Looking Ahead** For me, EMC 2025 was not just a conference—it was a turning point. I left Hamburg more confident than ever that we are moving toward a future where **data replaces estimation** and **automation replaces uncertainty**. At QuantoLux, we remain committed to: - Integrating OES into metallurgical workflows - Working with partners to implement smart, data-based process control - Helping the industry achieve its sustainability goals through precision and efficiency I want to thank GDMB for organizing such a high-quality event, and everyone who took the time to connect with me. I return to Ulm inspired and motivated to keep pushing the boundaries of what’s possible in modern metallurgy.
