During the MAT-DAYS 2025, held on 17–18 September 2025 at the New Design University St. Pölten (Austria), A2LT activities were disseminated through a dedicated exhibitor booth and a presentation. The presentation focused on providing an overview of the A2LT lightweighting platform and its role in promoting advanced lightweight technologies in Austria. It also highlighted the international engagement within the European Lightweight Cluster Alliance (ELCA) and the European Lightweighting Network (ELN). Furthermore, the projects ATIMA and DeremCo were presented as examples of ongoing initiatives contributing to innovation and sustainability in advanced materials. Participation in MAT-DAYS 2025 thus served as an excellent opportunity to raise awareness, exchange knowledge, and strengthen cooperation within the Austrian plastics industry.
