HERNANDEZ PEREZ, Ricardo et al. Handling of rice husk as postharvest residue and its conversion into nanocellulose. Mundo nano [online]. 2023, vol.16, n.30, e00059. Epub 14-Ago-2023. ISSN 2448-5691. https://doi.org/10.22201/ceiich.24485691e.2023.30.69697.
The environmental lack awareness of agricultural producers and poor government policies for waste management is one of the challenges faced by agroindustrial companies. The nanobiocomposites production has been recognized recently with the obtaining of cellulose. Therefore, the objective of this work is the obtaining and characterization of nanocellulose from polluting residues of rice (Oryza sativa L.) Var. “Morelos A-2010”, in the state of Morelos. The rice husk was sieved and processed by alkaline extraction, blanching, followed by an acid pretreatment. The cellulose was treated with acid hydrolysis (H2SO4) and sonication to produce nanocellulose. The samples at the end were processed by (FTIR), (DSC) and morphological visualization, by (SEM). The results showed potential yields of 29 to 41% cellulose 29 to 41% cellulose and its subsequent process allowed the formation of nanocellulose with a length between 86-173 nm, thus proving that this waste can have a sustainable management and become a recyclable product.
