PRESS RELEASE: Alternatives to toxic phenol compounds used in glues are being developed from softwood tannins
Finnish softwood bark contains large amounts of water-soluble tannin-polyphenols, which can be used as renewable alternatives to the fossil and toxic phenol compounds widely used in glues. VTT Technical Research Centre of Finland, the Natural Resources Institute Finland (Luke) and the South-Eastern Finland University of Applied Sciences (Xamk) are developing an industrial production method for a polyphenol extraction process as part of the SusBinders project.
