Green and sustainable pretreatment methods for cellulose extraction from lignocellulosic biomass and its applications: A review

Lignocellulose biomass (LCB) is a plant biomass mainly composed of cellulose, hemicellulose, and lignin. Cellulose is the most abundant biodegradable polymer on Earth and is very useful for various applications. However, the complex structure of lignocellulosic biomass, in which cellulose is tightly bound to hemicellulose and lignin, poses significant challenges in the isolation of cellulose from LCB components. This necessitates efficient pretreatment techniques to enable cellulose separation. Conventional pretreatment methods are not sustainable because they involve the use of harsh chemicals, elevated temperatures, high energy consumption, low productivity, and the formation of fermentation inhibitors which…
