Objectives
The generic objective of the project is to innovate in obtaining bioproducts through the willow biorefinery, evaluating the possibilities of short rotation forestry plantations with improved material of the species as an economically and environmentally beneficial alternative for many abandoned or underused lands in Galicia, or as a complement for livestock farms that need to diversify with more environmental alternatives (effluent filter, etc.).
Results
Several demonstration short rotation plantations with willows (with the Terranova clone) in the municipalities of San Sadurniño and Mesía (A Coruña) have been carried out and analysed. Different equations for total, wood and bark dry biomass have been developed. In addition, biorefinery methodologies have been fine-tuned to obtain various willow bio-products: xylitol from wood, and condensed tannins from bark. The project has shown that short rotation forestry with willows can be an economically viable and environmentally responsible alternative for many lands in Galicia that are currently abandoned or underused.
