𝗪𝗵𝗶𝗰𝗵 𝗳𝗿𝗶𝗰𝘁𝗶𝗼𝗻 𝗽𝗮𝗶𝗿𝗶𝗻𝗴 𝗶𝘀 𝘁𝗵𝗲 𝗺𝗼𝘀𝘁 𝘀𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲? The honest answer: it depends. What works for a high-speed train won’t necessarily be the right solution for a metro. Sustainability in friction pairing isn’t a one-size-fits-all answer – it’s a system-level decision. 🔍 With our 𝗦𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗙𝗿𝗶𝗰𝘁𝗶𝗼𝗻 𝗣𝗮𝗶𝗿𝗶𝗻𝗴 approach, we evaluate every pairing across five dimensions:  🔹 Particulate matter emissions (fine dust)  🔹 Circularity  🔹 CO₂ footprint  🔹 Environmental material compliance   🔹 Energy savings in operation    The key is clear: don’t optimize what’s easiest – optimize what has the greatest impact in each specific application.    💡 A real-world example: Brake discs ensure reliable braking - but after every stop, it must be accelerated again. Depending on the application lighter aluminum disc or an optimized design can reduce energy consumption in operation through weight reduction or aerodynamic drag and ventilation losses. And circular economy is already built in over 80% of recycled steel scrap that flows back into our cast steel brake disc. ✔️ Backed by state-of-the-art test rigs, our experts also contribute to the ISO/TC 269 working group – defining practical methods to measure particulate emissions in rail.    👉 Meet us at #EuroBrake2026 – we’ll be sharing insights about reducing particulate matter emissions. 📌 In the upcoming weeks, we’ll take a closer look at each of the five dimensions – stay tuned. #TeamKnorrBremse #BrakingTechnology #GreenTech #EuroBrake2026
