The biorefinery concept potentially provides a sustainable route to multiple products, such as bioenergy, biochemicals, food, feed, and other bio-based materials, by fractionation of biomass components into intermediates and product recovery using relevant conversion technologies. Accordingly, the biorefinery concept is recognized as a strategic means to extract value from biomass and realize a circular bioeconomy, in which all outputs are inputs for other processes, resulting in no waste. To achieve this goal, pretreatment is a key step to separate biomass components into high-purity fractions for further processing. Conventional pretreatment methods, such as steam explosion and dilute acid pretreatment, successfully increase cellulose accessibility to enzymes. However, soluble hemicellulose and lignin are difficult to recover from the hydrolysates for further conversion, despite having utility in the production of prebiotic xylooligosaccharides (XOS), and antioxidant and antimicrobial agents, respectively. In this study, current technology used for biomass conversion toward the bioeconomy concept is discussed. The transition from common pretreatment to greener pretreatment using deep eutectic solvents (DESs) as alternatives to ionic liquids and the functional role of DESs in biomass separation are described. An integrated platform for the production of XOS from hemicellulose, antioxidant, and antimicrobial agents from lignin, and biofuel (such as ethanol) is proposed, along with future perspectives on the circular bioeconomy. © 2022 Elsevier Inc.
