Ecofriendly strategies for the production of nanocellulose from agro-industrial wastes
| Resumo: | The high exploitation of non-renewable resources has served as a motivation for an intensive research and development of new types of bio-based and degradable feedstocks derived from natural sources. Lignocellulosic biomass is rich in biopolymers, and can be obtained from several sources, among which are the residues from agricultural and industrial lignocellulosic crops. The cellulose extracted from the biomass can be fragmented giving rise to a nano-bio-based material-nanocellulose (NC). In recent years, studies on nanocellulose resulted in a wide range of applications. This work focuses on the recent developments about the valorization of lignocellulosic biomass obtained from different lignocellulosic agro-industrial crops, as a source of NC. Aspects discussed are (i) structure of lignocellulosic biomass and their influence on the nanocellulose properties (ii) more sustainablel biomass pre-treatments and nanocellulose extraction procedures, (iii) latest technological applications. A survey of the current knowledge is made in order to identify future opportunities of nanocellulose in the framework of a resource efficient bioeconomy. |
