A new national research programme recognizes EPFL’s expertise
Separation technologies are the workhorses of modern society. Essential for isolating specific components from gas, liquid, or solid mixtures, they provide the purified water, food, and pharmaceuticals we consume, and the materials that go into our homes, cars, and electronic devices. Improving the performance of separation technologies is essential for addressing many global challenges, such as capturing CO₂ directly from the air, making ammonia production more energy-efficient, and recovering critical metals from waste streams.
