Important results from the project
The project successfully demonstrated that tree bark can be upgraded into wood treatment formulations, replacing harmful chemicals. Key results include a fully bark-based wood coating and a VOC-absorbing composite. Challenges remain regarding water and UV stability. The project trained several early-career researchers. In the long term, the results support the development of new bark-based products, with ongoing research into industrial applications.
Expected long term effects
The project is expected to lead to increased use of bark-based materials in the construction and wood industry, reduce the need for fossil and harmful chemicals and promote circular bio-based solutions. The research has already attracted industrial interest and may eventually contribute to new products such as impregnation agents, surface treatments and adhesives. In addition, the project has strengthened European cooperation and expertise in sustainable materials development.
Approach and implementation
The project followed a structured work package model, integrating key objectives. Activities aligned well, though wood impregnation faced challenges. The schedule was mostly followed, with minor shifts due to different project start dates. Collaboration was strong, with shared materials, research visits, and regular meetings. Dissemination efforts intensified late; having a dedicated partner for communication, dissemination, and exploitation would have been beneficial.
