WooBAdh - Environmentally-friendly bioadhesives from renewable resources

In the joint research project ERA CoBioTech Call 1: "WooBAdh - Environmentally-friendly bioadhesives from renewable resources" the Chair of Forest Biomaterials cooperates with four partners: University of Santiago de Compostela (E), Université de Lorraine (F), University of Ljubljana (SLO) and Fraunhofer ICT (D) as well as with associated industrial partners in the development of formaldehyde-free wood adhesives. In Freiburg the research is focused on the synthesis and formulation of adhesive based on different natural polyols as lignins and tannins in order to increase their added value and push their general material use.

Project duration: April 2018 - March 2021

Funding: ERA CoBioTech; Federal Ministry of Education and Research  (BMBF) by means of Projektträger Jülich (PtJ); project  number 031B0572A

Optical stability of transparent Beech wood

Transparent wood can be produced by delignification or bleaching of wood and subsequent infiltration and polymerization with a matrix polymer having a refractive index close to wood/cellulose. The resulting wood exhibits high transparency, high haze and improved mechanical properties compared to the pure matrix polymer. The project investigates the production of transparent wood from Beech (Fagus sylvatica), the most common broadleaf tree in Germany. The application of different chemical pretreatment methods of beech wood and the infiltration with various matrix polymers is tested. Besides optical and mechanical properties also the optical stability of transparent beech wood is examined.

Project duration: January 2019 - December 2020

Funding: The project is funded by the Gesellschaft zur Förderung der forst- und holzwirtschaftlichen Forschung an der Universität Freiburg im Breisgau e.V. (GFH).
