“…This narrows down the enzymatic hydrolysis rate for raw LCB. The properties of lignin including the non-productive binding and enzyme inactivation also lead to lower enzymatic hydrolysis efficiency (Zhou et al 2021 ).…”

The concept of biorefinery has been advancing globally and organosolv pretreatment strategy has seen an upsurge in research due to its efficiency in removing the recalcitrant lignin and dissolution of cellulose. The high-performance organosolv system uses green solvents and its reusability contributes concurrently to the biorefinery sector and sustainability. The major advantage of the current system involves the continuous removal of lignin to enhance cellulose accessibility, thereby easing the later biorefinery steps, which were immensely restricted due to the recalcitrant lignin. The current system process can be further explored and enhanced via the amalgamation of new technologies, which is still a work in progress. Thus, the current review summarizes organosolv pretreatment and the range of solvents used, along with a detailed mechanistic approach that results in efficient pretreatment of LCB. The latest developments for designing high-performance pretreatment systems, their pitfalls, and advanced assessments such as Life Cycle Assessment along with Techno-Economic Assessment have also been deliberated to allow an insight into its diverse potential applicability towards a sustainable future.

“…Acetone is used for organosolv pretreatment followed by methyl isobutyl ketone (MIBK) (Chin et al 2020b ). They have high solubility for lignin as well as lignin-based compounds (Zhou et al 2021 ). Mild acetone pretreatment has shown excellent results in laboratory-scale lignin solubilisation.…”
