The sixth Exchange of Experience on Exhaust Air Purification of the Sächsische Textilforschungsinstituts e.V. (STFI) took place on 6 September 2023 in Chemnitz. With a total of 41 participants, the exchange of experience was again held as a hybrid event. A total of seven presentations were given at the event. The main topics were information on guidelines and regulations such as the BREF process (Best Available Techniques Reference or Best Available Techniques Reference Document) and its impact on the textile industry or the revised BAT reference document for the textile industry, experiences with the implementation of the new TA-Luft from the point of view of a specialist authority and the use of energy-efficient technologies such as heat recovery, UV light and plasma in exhaust air purification. In the subsequent panel discussion, representatives from industry, associations and authorities openly and without ideology discussed current key topics, problems in industry and the need to focus on risk-, fact- and science-based as well as economic solutions. The sixth Exchange of Experience on Exhaust Air Purification was accompanied by a trade exhibition where three exhibitors showed their products and services.

We would like to thank all participants for a successful event and look forward to seeing you again at the 7^th exchange of experience on exhaust air purification on 9 September 2025!
