Four graduates of the doctoral program in Plastics Engineering presented their research at the 2026 ÖWGP Doctoral Prize ceremony on October 20, 2026, at the Vienna University of Technology. The presentations addressed current issues in plastics engineering, the circular economy, and sustainable materials development.

The dissertations presented highlight the thematic breadth and scientific expertise of the Department of Plastics Engineering at the Montanuniversität Leoben.

• Ulrike Kirschnick presented her thesis titled “On the Duality of Technical Specifications and Methodological Choices in Life Cycle Assessment for the Evaluation of Bio-Based and Circular Composites.” Her research focuses on the influence of technical requirements and methodological decisions on the life cycle assessment of bio-based and circular composites.
• Zahra Shahroodi presented her thesis titled “Upcycling of Polypropylene Glass Fiber Composite Regenerates Through a New Technological Approach.” The focus is on developing new technological approaches for the upcycling and recycling of polypropylene-glass fiber composites.
• Christoph Waly presented his dissertation, “Nature-derived Concepts of Toughening—Mechanisms and Strategies for Polymeric Materials.” The focus is on nature-inspired mechanisms and strategies for improving the toughness of polymeric materials. 
• David Zidar presented his dissertaton “Impct of Viscous Dissipation on Polymer and Mold Steel in Injection Molding”. The effects fo viscous dissipation on polymer and mold steel in the injection molding process. The study contributes to a deeper understanding of thermal and process-related relationships in injection molding technology.

The participation of the four early-career researchers in the ÖWGP Doctoral Award underscores the importance of the research being conducted at the Department of Plastics Technology in Leoben for addressing current challenges in the fields of materials development, production engineering, and sustainability.

We would like to thank the ÖWGP for organizing the event and supporting early-career researchers, and we congratulate our PhD students on presenting their research.
