N2 - Sawdust (SW) biomass contains lignocellulosic (LGC) valuable biopolymers in its composition. Specifically, isolation of cellulose from SW is an option to reincorporate an inherent by-product of sawmill industry into potential raw material for bioplastics industry. The final properties and chemical composition of LGC biomass vary in dependence of the source and the isolation type. This motivates the study of the extraction process before proposing the cellulose-rich biomass for fabricating new products. This work presents the structural and thermal characterization of two different types of SWs. One from Durango (SWD) and other from Hidalgo (SWH), regions of Mexico, for cellulose isolation, through alkali and bleaching pre-treatments. Results are discussed in terms of effectiveness on the removal of extractives, lignin and hemicellulose. The characteristic functional groups, the thermal stability and chemical composition of biopolymers were analyzed. The extracted cellulose-rich biomasses (SWD-L2 and SWH-L2) are proposed as raw materials to migrate towards renewable resources in bioplastics industry.
