Scientists have developed tannin extraction from softwood bark. At least 130 kg of crude tannin powder can be produced from one ton of dry wood bark, still leaving 87% of the original bark mass available for incineration. In Finland, tannin could replace, in particular, fossil-based phenols in adhesives used in the wood products industry.
