As one of the world’s most abundant biomass, lignocellulosic materials such as rice husk (RH) has been recognized for its various potential usages. Electrospun nanofibrous mats have been fabri-cated from various natural and synthetic polymers and offers a wide range of promising criteria suitable for wound dressing applications. Natural polymers have grabbed considerable attention due to their desirable properties. Therefore, the application of cellulose-derived materials from agricultural waste becomes crucial as a green alternative to produce electrospun wound dressing with excellent wettability, porosity and tunability to promote wound healing at relatively low costs. Interestingly, a specific study on the utilization of cellulose extracted from RH to produce electrospun nanofibrous mat remains unreported. Therefore, this work aimed to investigate the feasibility of using RH as a source of raw materials to create nanofibrous mats for use as pro-spective wound dressing materials. In this paper, cellulose extracted from RH will be converted into its derivate, cellulose acetate (CA) and electrospun. The nanofiber will be characterized by Scanning Electron Microscope (SEM), Attenuated Total Reflectance- Fourier transform spectros-copy (ATR-FTIR), water contact angle to evaluate the main properties of the electrospun nano-fibrous mat.

Rice husk (RH) is the by-product of the rice milling industry, and its primary disposal via burning can lead to detrimental environmental implications. While literature primarily focused on the potential of its silica component, the cellulosic constituent, which can be of applied value in the biomedical field, appears sparsely reported. Therefore, this review paper critically discusses both the silica and cellulose components of RH investigated for various biomedical uses (adsorbents, drug delivery systems, antioxidant and antitumor activities), and provides the elaborative overview of the chemical extraction methods for both components, while highlighting the needs for optimizing the extraction process for large scale industrial considerations. Discussions on several limitations of the current knowledge that mitigated readiness for biomedical applications (e.g. inadequate data from animal studies and clinical trials, as well as the lack of analytical confirmatory tests and non-standardized methods) are also presented. Considering the medicinal properties of RH, the possible utilization of its cellulose content as a new biomaterial for wound healing application is theorized. The information gathered here justifies the use of this agricultural biomass as a new source of economic wealth for biomedical industries, while minimizing the environmental threat that can be associated with its disposal.

Over the last few decades, the use of agro by-products as a biopolymer for various applications has attracted significant interest of researchers. Rice husk (RH) is one of the agro by-products produced abundantly worldwide and a great deal of studies in extracting and utilizing silica from RH have been reported but scarcely for its cellulose components. A specific study on the utilization of cellulose extracted from RH for the electrospinning process also remains unreported. Chemical pre-treatment seems to be the most crucial step which improves the elimination of the cementing components and exposing the cellulose for further applications. This study aimed to explore the potential of RH as a source of raw material to produce cellulose nanofiber. The cellulose was extracted by acid pre-treatment, alkaline treatment at varying sodium hydroxide (NaOH) concentrations, followed by bleaching treatment with sodium hypochlorite for complete removal of the amorphous region. The resulting cellulose was characterized and the main properties (morphology and sizes) of the extracted cellulose were made using scanning electron microscopy (SEM). The findings revealed the almost complete removal of the noncellulosic components for the subsequent production of electrospun cellulose nanofibers. Therefore, the output of the cellulose from this underutilized agro-waste has commercial application potential that can add value and be further utilized for the electrospinning process.
