“…Mechanical, chemical (Ray and Sarkar 2001), physical-chemical (Abraham et al 2013), and biological (Evans et al 2003) treatments have been employed to separate fibers from the natural cellulosic fibers. Steam explosion is an effective low cost and environmentally friendly pretreatment method (Sheng et al 2014).…”

The chemical and structural properties of kenaf fibers that were treated at different steam pressures during the steam explosion process were investigated. With increased steam pressure, a higher percentage of cellulose and acid-insoluble lignin and a lower content of hemicellulose and pectin were obtained. This result was further confirmed by Fourier transform infrared (FTIR) spectroscopy. X-ray diffraction (XRD) studies revealed that the steam-exploded kenaf fibers were more crystalline than the raw kenaf fibers, and that excessive steam pressure above 3 MPa damaged the cellulose crystalline structure. Scanning electron microscopy (SEM) analysis showed a change in the surface morphology of the treated kenaf fibers. The lower content of gums and the effective defibrillation of steam-exploded kenaf fibers demonstrated the potential of steam explosion treatment in applications of kenaf fibers.

“…Cellulose is one of the biodegradable and renewable structural plant polymer which can be processed into whisker-like micro fibrils, microcrystalline cellulose (MCC), nanocrystalline cellulose (NCC) and many more [4,5]. It can be obtained from agricultural by-products such as cotton fiber, kenaf, hemp, corn stalk, bagasse and RH.…”

Abstract. Microcrystalline cellulose (MCC) was extracted from local agricultural residues, rice husk (RH). RH undergone alkaline, bleaching and acid hydrolysis treatments. Nitric acid was used in the hydrolysis process as a potential acid to replace strong acids such as hydrochloric and sulphuric acids. Hydrolysis of RH was carried out by using different molarity of nitric and hydrochloric acids (control). The properties of MCC obtained such as % yield, crystallinity index (CrI) and functional group present were studied. % yield shown a comparable result regardless of different acid used. Whilst Fourier transform infrared (FTIR) spectroscopy showed the progressive removal of non-cellulosic constituents. X-ray diffraction (XRD) analysis revealed that the crystallinity increased with successive treatments regardless different molarity and acids used. The results showed potential of nitric acid to be used in MCC isolation process.

“…There are some comprehensive articles which have reviewed various issues related to different nanocelluloses and their obtainment methodologies and potential applications (Isogai 2013;Klemm et al 2011;Habibi et al 2010;Klemm et al 2009). New efficient methods for production of various nanocellulose filler types include enzymatic, chemical, and physical methodologies for their isolation from wood sources and forest/agricultural waste residues (Nair et al 2014;Qamhia et al 2014;Abraham et al 2013;Chen et al 2011a, b;Abraham et al 2011;Syverud et al 2011;Kaushik and Singh 2011;Cherian et al 2010;Klemm et al 2009;Fukuzumi et al 2009;Stelte and Sanadi 2009;Jonoobi et al 2009;Moran et al 2008;Abe et al 2007;Janardhnan and Sain 2006;Chakraborty et al 2005).…”

Green composites are increasingly promoted for sustainable development considering the growing awareness of environmental and waste management issues. Recent advances in natural fiber development, and nanocomposites research area generate significant opportunities for obtaining materials from renewable resources with improved properties and suitable for different applications. Green composites are made from both renewable resource-based polymers (biopolymers) and bio-fillers (including nano-type fillers), with a positive environmental impact. Green composites based on biopolymer matrix (plasticized starch) have been obtained by combination with various bio-fillers (beech wood sawdust, fir tree needles, beech wood lignin). Their structure and properties were further investigated through Fourier Transform Infrared (FTIR) spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), and TG/DTG/DTA simultaneous thermal analysis methods, as well as by water uptake and opacity measurements. The results are presented in this chapter.
