Emission control is recognized as a technology that is traditionally very important for clean air and will enable progress in other areas - most notably the energy transition, which is considered one of the most pressing issues of our time. In the 2-day conference we aim to bring together the international community in the field of emission control and to present and discuss new challenges, concepts and solutions in the scientific field. We are expecting around 100 experts and participants from various fields to attend the conference. By bringing together experts from engineering, physics, chemistry, material science and many more, we aim to facilitate a cross-disciplinary exchange among researchers following different strategies to reach the same long-term goals: Identify upcoming trends and challenges as well as highlight new concepts and technologies for a clean and healthy environment.
