“…The decrease of the CNC yield with increasing of hydrolysis time has been previously reported for the extraction of CNC from raw cellulose-rich materials [26,27,32]. Comparatively, with regard to the starting raw materials, the yield of the as-isolated CNC was higher than that of the CNC isolated from rice straw (4.83-6.43%) [33], and red algae (Gelidium elegans) (8.07%) [10].…”

“…Marine biomass, especially algae derivatives, contains low amounts of natural physicochemical barriers, making the cellulose accessible without a severe chemical treatment. It also contains a higher yield of carbohydrates and grows faster than typical terrestrial lignocellulosic biomass [10,13,14]. Marine biomass is, thus, considered to be a potential source for the production of cellulose fibers and its derivatives such as CNC.…”

“…More recently, CNC were successfully extracted from marine biomass such as posidonia oceanica ball and leaves [11,12] and Gelidium elegans [10]. Marine biomass, especially algae derivatives, contains low amounts of natural physicochemical barriers, making the cellulose accessible without a severe chemical treatment.…”

“…Cellulose nanocrystals (CNC) is the nanoscale form of cellulose which can be produced in various morphological shapes such as sphere-like, rod-like, ribbon-like, or needle-like shape, having a compact structure of ordered cellulose chains stabilized by inter and intra-molecular hydrogen bonding, which make very interesting solid crystalline nanoparticles with unique characteristics [6][7][8][9]. Starting from pure cellulose fibers, CNC can be extracted by various methods such as acid hydrolysis, TEMPO-mediated oxidation, mechanical disintegration and enzyme-assisted hydrolysis [5,10]. Among these methods, acid hydrolysis process represents the most effective method, where the cellulose fibers are subjected to concentrated acid to hydrolyze the amorphous domains of the cellulose chains and leave the crystalline domains unaltered [7].…”

phone (+2126) 620 10 620 Highlights  Cellulose nanocrystals (CNC) were successfully extracted from red algae waste  CNC exhibit a needle-like shape and a diameter of 5-9 nm, and a length of 289-315 nm  PVA nanocomposite films with different CNC contents were prepared by solvent-casting  Nanocomposites with high mechanical performance and good transparency were obtaine Version postprintComment citer ce document : El Achaby, M., Kassab, Z., Aboulkas, A., Gaillard, C., AbstractRed algae is widely available around the world and its exploitation for the production of agar products has become an important industry in recent years. The industrial processing of red algae generates a large quantity of solid fibrous wastes, which constitutes a source of serious environmental problems. In the present work, the utilization of red algae waste as raw material to produce high-quality cellulose nanocrystals (CNC) has been investigated, and the ability of the as-isolated CNC to reinforce polymer has been studied. Red algae waste was chemically treated via alkali, bleaching and acid hydrolysis treatments, in order to obtain pure cellulose microfibers and CNC. The raw waste and the as-extracted cellulosic materials were successively characterized at different stages of treatments using serval analysis techniques. It was found that needle-like shaped CNC were successfully isolated at nanometric scale with diameters and lengths ranged from 5.2 ± 2.9 to 9.1 ± 3.1 nm, and from 285.4 ± 36.5 to 315.7 ± 30.3 nm, respectively, and the crystallinity index ranged from 81 to 87 %, depending on the hydrolysis time (30, 40 and 80 minutes). The as-extracted CNC were used as nanofillers for the production of polyvinyl alcohol (PVA)-based nanocomposite films with improved thermal and tensile properties, as well as optical transparency. It is shown that the addition of 8 wt % CNC into the PVA matrix increased the Young's modulus by 215 %, the tensile strength by 150 %, and the toughness by 45 %. Additionally, the nanocomposite films maintained the same transparency level of the neat PVA film (transmittance of ∼90% in the visible region), suggesting that the CNC were dispersed at the nanoscale.

“…Typical sizes of cellulose crystallites range from about 3 to 30 nm in thickness and few hundreds of nm in length, depending on the plant source (Elazzouzi-Hafraoui et al 2008; Eichhorn 2011). Nanocellulose crystals also can be obtained from other cellulose sources such as algae (Feng et al 2015b;Hai et al 2015;Chen et al 2016b), tunicin (Dufresne 2012Piao and Zhang 2016), and bacteria (discussed in a different section). Studies related to the use of CNCs in packaging are listed in Table A in the Appendix of this article (see first column, in which the type of nanocellulose is identified).…”

This review article was prompted by a remarkable growth in the number of scientific publications dealing with the use of nanocellulose (especially nanofibrillated cellulose (NFC), cellulose nanocrystals (CNC), and bacterial cellulose (BC)) to enhance the barrier properties and other performance attributes of new generations of packaging products. Recent research has confirmed and extended what is known about oxygen barrier and water vapor transmission performance, strength properties, and the susceptibility of nanocellulose-based films and coatings to the presence of humidity or moisture. Recent research also points to various promising strategies to prepare ecologically-friendly packaging materials, taking advantage of nanocellulose-based layers, to compete in an arena that has long been dominated by synthetic plastics. Some promising approaches entail usage of multiple layers of different materials or additives such as waxes, high-aspect ratio nano-clays, and surface-active compounds in addition to the nanocellulose material.While various high-end applications may be achieved by chemical derivatization or grafting of the nanocellulose, the current trends in research suggest that high-volume implementation will likely incorporate water-based formulations, which may include water-based dispersions or emulsions, depending on the enduses.

As of November 2016, a search of this combination of terms showed about as many publications since the start of 2015, compared to all preceding years combined. Given such an acceleration of research around the world, it makes sense to ask whether this high amount of research effort has yet borne significant fruit. In light of this question, the emphasis of this review article is on research publications that shed light on known challenges to the successful implementation of nanocellulose products to enhance the performance of packaging.In principle, a nano...
