The request for alternative sources of energy has led to evaluating untapped routes production, such as using abundant and low-cost waste materials, e.g., lignocellulosic wastes, the substrate biological processes aimed at biofuel production. This study focused on peanut shells (PS) valorisation via anaerobic digestion (AD). Two emerging pretreatments, i.e., organosolv ultrasounds, were investigated unlock full AD potential PS. impact a substrate-to-solvent ratio in pretreatment was (i.e., 1:5 vs. 1:10 1:20). Different exposure times tested ultrasound pretreatment, corresponding applied densities 30,000, 12,000, 6000 kJ/kg VS, respectively. Organosolv achieved maximal polyphenol solubilisation, 4.90 mg/g TS, when increasing ratio, whereas methane production did not benefit from being comparable with that raw PS most 55.0 mL CH4/g VS). On other hand, ultrasounds mainly affected sugar solubilisation (up 37.90 TS), enhancing up an extra 64%, highest density. route would further downstream steps recover biomolecules released liquid fraction, provided slurry suitable direct AD.

Abstract Glycerol organosolv (GO) pretreatment has been revealed to be potent in selectively deconstructing the lignocellulosic biomass and effectively enhancing its enzymatic hydrolysis, but conventional solid washing GO lignin extraction processes frequently consume large amounts of water, resulting additionally difficulty recycling glycerol. In this study, an anhydrous two-step process was explored, followed by membrane ultrafiltration glycerol lignin. The results showed that residual after atmospheric (AGO) necessary for subsequent operation high-solid hydrolysis. Washing with ethanol desirable as alternative water only a low content 5.2% resided substrate. Membrane helpful extracting AGO from liquor, which high 81.5% made regenerated cellulose (cut-off 1 kDa) under selected conditions. With characterization membrane-extracted lignin, it observed first time well-preserved structure G/S type. Moreover, enriched reactive groups, i.e. β -O-4′ linkages aliphatic hydroxyl very likely due grafting onto via α -etherification reaction. allowed 86% 92% recovery ∼78% distillation energy savings, applicable use organic solvents.
