Abstract:
Current demand for bio-based nanoparticles as a substitute for synthetic nanoparticles has increased due to their physicochemical properties, biodegradability and biocompatibility, and lignocellulosic wastes can be exploited for the production of cellulose derived nanoparticles. Nanocellulose (NC) have applications in many different areas, ranging from automotive manufacturing, agricultural, medicine, food industry, biotech industry and extending to the energetic field. Yet, the recalcitrance of the lignocellulosic material to deconstruction, requires pre-treatments as an earlier and necessary step in the process to get NC. Therefore, the aim of the work focuses on the recent developments about the valorization of those lignocellulosic wastes as a source of NC, by discussing (i) how the characteristics of different biomasses and residues (coconut fiber, olive pit, rice husk, cork wastes) influence the potential NC production, (ii) how treatments and extraction proceduresalso influenced the potential production of NC. Results obtained after using an alkali pretreatment show that cork waste is the most promising feedstock, offering high cellulose content and manageable lignin levels, which favor efficient cellulose nanocrystal (CNC) production.
