The SuperBark project was presented at TAPPI Nano – International Conference on Nanotechnology for Renewable Materials, 8-11 July 2025 in Girona, Spain.
TAPPI Nano 2025 brought together top researchers, industry leaders, and innovators for three days of cutting-edge science, networking, and collaboration. The annual event offers an opportunity to learn from world-class researchers, engage with global industry leaders, and explore the latest in nanocellulose applications, materials chemistry, and green innovation. SuperBark was showcased by Senior Scientist Panu Lahtinen from VTT Technical Research Centre of Finland (VTT). The presentation focused on the demonstration of industrial softwood bark in CNF barrier coatings and films, and highlighted several key findings of the SuperBark project:
- Bark residue as a low-cost raw material has great potential in bio-based functional coatings
- The residue can be processed at relatively high consistency, which enables higher loadings in coating formulations
- Bark residue has potential in e.g. barrier coating, barrier films and adhesives.

As the coordinator of SuperBark, VTT leads the production of bark-based components (WP2) for use in developing adhesives and coatings and is also involved in the development of bark-based adhesives (WP3).
