Biomass wastes have great potential for renewable energy and value-added product synthesis. The key lies in developing pretreatment techniques to overcome barriers in lignocellulosic materials and find cheap, effective, environmentally friendly methods. The use of green solvents and the role of choline chloride (ChCl) in them are areas of interest and ongoing research.
Biomass wastes exhibit a great potential to be used as a source of non-depleting renewable energy and synthesis of value-added products. The key to the valorization of excess lignocellulosic biomass wastes in the world lies on the pretreatment process to recalcitrant barrier of the lignocellulosic material for the access to useful substrates. A wide range of pretreatment techniques are available and advances in this field is continuously happening, in search for cheap, effective, and environmentally friendly methods. This review starts with an introduction to conventional approaches and green solvents for pretreatment of lignocellulosic biomass. Subsequently, the mechanism of actions along with the advantages and disadvantages of pretreatment techniques were reviewed. The roles of choline chloride (ChCl) in green solvents and their potential applications were also comprehensively reviewed. The collection of ideas in this review serve as an insight for future works or interest on biomass-toenergy conversion using green solvents.
