ABSTRACT
Depletion of natural resources, pollution management, and growing energy demands have been the major challenges for the last few decades. Lignocellulosic biomass was found to be a potential alternative with its unique characteristics, such as being eco-friendly and acting as the best substitute for the current energy resources. An effective pretreatment process plays a significant role in turning biomass into value-added products. Several new methods are unearthing the unseen potential of lignocellulosic biomass in the conversion to biofuels. This article provides insight into various conventional pretreatment techniques and the emerging advanced techniques for better conversion of biomass and helps to choose the better pretreatment technique for a specific lignocellulosic biomass source. The present chapter focuses on the use of various advanced pretreatment strategies such as ionic liquid, deep eutectic solvents, supercritical fluids, and cosolvent for conversion of various lignocellulosic biomasses for biofuel and biomaterial production. The comparative advantages of various advanced pretreatment processes were also assessed.
