A sustainable valorization of chestnut wood waste is proposed through microwave-assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin-rich fraction, used to synthesize a PVA-based biopolymer. Antioxidant, enzymatic, and antibacterial activities are investigated for the obtained fractions.

Abstract
A sustainable valorization of chestnut wood waste is proposed through microwave-assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin-rich fraction, used to synthesize a PVA-based biopolymer. Antioxidant, enzymatic, and antibacterial activities are investigated for the obtained fractions.File in questo prodotto:
