BioWILL is a Interreg NWE funded project focusing on integrated "zero waste" biorefinery utilising all fractions of willow feedstock for the production of high to medium based bio-chemicals/materials, renewable energy in the form of bio methane production and natural fertilisers. Bark residue and bark-free willow pulp will be converted into safe food quality biodegradable catering utensils packaging material to replace fossil derived plastics. Then, to complete the cycle, once used, these materials will be collected and hydrolysed and used as a feedstock in an innovative bio-energy anaerobic digestion system producing biogas suitable for grid injection. The digestate will be evaluated as a soil nutrient and carbon storage medium. High value salicylates from the willow bark will also be used for medical applications.
Selected varieties of willow are currently being planted on sites in France and Ireland.
