The pulp and paper industry and the wood product industry in Finland together produce three million tonnes of softwood bark as waste every year. Most of this is used in energy production, but useful raw materials can also be extracted from softwood bark to create bio-based products and materials. Rehap partner VTT has developed a method to extract a high yield of tannins from bark.
