Goal: Biowood is a large project sponsored by the Research Foundation Flanders (FWO) and contributing to the development of a new wood-based bioeconomy in Flanders through multidisciplinary research in forest and chemical engineering and economics. This research will focus on (i) quantifying the current woody biomass feedstock supply in Flanders, (ii) predicting the future woody biomass in Flanders using the Sim4Tree decision support system (DSS), (iii) creating added value for wood flows based on a lignin-first process opening up opportunities for using the new derived molecules in the agro-industry and (iv) evaluating the sustainability of the lignin-first derived products including optimising locations of the biorefineries using the MooV DSS.
