Dissemination of mobile exhibitions at TU Wien

24. March 2026
A dissemination of mobile exhibitions from the ReBuilt project took place at TU Wien. The mobile exhibitions highlight usage of circular materials, such as Bio-composite panels and recycled concrete, through real-life demos in Maribor and Munich.

Students and project partners jointly prepared mobile exhibitions within the ReBuilt project, focusing on circular materials and sustainable construction solutions. The exhibitions presented real-life demonstrations from Maribor and Munich. Innovative bio-composite acoustic panels and structural concrete made with 100% recycled aggregates were tested in practice at those sites. 

  • Nigrad Demo Maribor
    The Nigrad Demo Maribor presented an innovative acoustic solution made from natural materials. In a real indoor environment in Dogoše, bio-composite panels based on hemp and lime were installed and tested for their effect on indoor spatial quality. The demonstration showed that these panels can significantly reduce reverberation and improve speech intelligibility, making interior spaces more comfortable for everyday use. At the same time, the demo highlighted the potential of low-impact, natural materials in sustainable construction.
  • Demo Munich
    The Munich demo focused on structural concrete made with 100% recycled aggregates from construction and demolition waste. It showed that recycled materials can be successfully used in real load-bearing structures such as piles, slabs, and walls. As part of our mobile exhibition, these materials and their practical application were presented through posters and photos, helping visitors better understand their role in circular construction. In this way, the exhibition connected technical innovation with public awareness and education.

With the help of posters and photos from the demonstration sites, the exhibition at TU Wien offered visitors an accessible insight into how circular approaches can help build a greener construction sector. For the Maribo demo a video was produced by nigrad, which was presented at the event at TU Wien.

As part of the programme, we also organized a walk with students to introduce them to recycled aggregates and their importance for sustainable construction. During the walk, they learned how demolition waste can be processed and reused as a valuable resource for new building materials. This gave them a direct insight into circular construction principles and the environmental benefits of reducing the use of virgin raw materials. The activity helped connect project results with hands-on learning and discussion.
