Better use of entire biomass of willow
VTT Technical Research Centre of Finland and Aalto University investigated how willow biomass can be utilised more efficiently. When processed correctly, willow is eminently suitable as a source of sugar in the production of ethanol. The lignin fraction formed as a by-product of the ethanol process and the fibres and compounds of willow bark are suitable for the manufacture of environmentally friendly chemicals and bio-based materials. According to the results of the joint project of VTT and Aalto University, after appropriate preparation and enzymatic hydrolysis, willow is highly
