Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.
