Birch bark is a valuable renewable raw material and an underutilised side stream of the forest industry. It is biodegradable, naturally abundant and rich in unique compounds such as betulin and suberin. These molecules contribute to the tree’s natural protection against moisture, environmental stress and microbial exposure.
Due to their natural structure, betulin and suberin offer functional properties such as hydrophobicity, durability and protective performance, making them promising building blocks for bio-based materials used in cosmetics, coatings, adhesives and other industrial applications.
