Scots pine wood was impregnated under vacuum with an aqueous 60% acetone solution containing about 10% softwood Kraft lignin. The impregnation treatment incorporated 6–8% of lignin (on wood dry mass) to the wood samples and caused a noticeable chan

Hydrothermal treatments (HTT) are used in the biorefineries to effectively valorize carbohydrate fractions and their products. However, lignin is often marginalized as a secondary component. Herein, we propose a new biorefinery approach focused on li
