From Forest Residues to Bio-Based Innovation: The CEforestry Story
16 February 2026
Across the Baltic Sea Region, large volumes of forestry side streams such as bark, sawdust and ash are underutilised and mainly burned for energy. CEforestry addressed this challenge by transforming these residues into high-value bio-based products. Through Interreg transnational cooperation, 30 partners from five countries combined research, industrial testing and regional data to develop practical solutions. A tannin-rich spruce bark extract showed strong antimicrobial performance in wastewater and pulp systems, matching or exceeding synthetic biocides. Industrial feasibility was demonstrated, and tannin-based applications proved commercially promising, including natural leather tanning and wastewater treatment. Tools such as an ArcGIS biomass map and a wood ash recycling planner supported regional uptake. The project demonstrated that cross-border cooperation can turn forestry residues into viable circular bioeconomy solutions. See the whole story in the file above:
