A biorefinery can turn plant material into useful products like bioethanol. Lignocellulosic biomass, which includes cellulose, hemicellulose, and lignin, can be used for bioethanol production. To make bioethanol efficiently, the lignin and hemicellulose need to be separated from the cellulose through a process called organosolv pretreatment. This method helps produce both bioethanol and pure lignin. The effectiveness of this process depends on factors like delignification rate and glucose conversion. Many studies have looked at how different pretreatment conditions affect these factors. Organosolv pretreatment is a promising method for creating valuable products from biomass in biorefineries.
