The initiative draws inspiration from tree bark natural protective qualities to create innovative wood treatment formulations and bark-based composites. Researchers extract polyphenols and other bark components for use in wood coatings and impregnation, leveraging their antimicrobial and insect-repellent properties. The project addresses climate change by developing sustainable wooden building materials with reduced environmental impact compared to conventional commercial alternatives. The international collaboration includes researchers from institutions in Norway, Slovenia, Poland, Latvia, and Finland.
