Unlocking the Potential of Lignocellulosic Biomass: Microwave and Hydrothermal Pretreatment to Improve the Production of High Value-Added Biorefinery Compounds.

ABSTRACT: This study is focused on the performance of a hydrothermal reactor (HTR) and microwave-assisted (MW) pretreatments of sugar beet pulp (SBP), orange peel (OP), brewer spent grain (BSG), and rice husk (RH) to evaluate the extraction of high-value biorefinery compounds. The influence of temperature, duration of treatment, and energy consumption on hydrolysis efficiency was evaluated by quantifying total reducing sugars (TRS), proteins (PR), polyphenols (TP), and volatile fatty acids (VFA). MW pretreatment at 180 °C for 30 min yielded 18% TRS and 24% PR from OP, respectively. In contrast, HTR at 200 °C, for 60 min, achieved higher yields of 32% TRS and 22% PR for OP. BSG showed higher responsiveness under HTR, reaching 25% TRS and 20% PR at 220 °C after 120 min. The highest VFA production was
