“…The first one can be obtained by mechanical defibrillation or enzymatic treatment of cellulose fibers [11] , which leads to individualization of cellulose nanofibers that compose the intrisic structure of the polymer . The second one is obtained by the isolation of crystalline domains present in the structure by hydrolysis of amorphous part using acid or enzymatic steps [12,13] . Concerning its actual applications, CNF is used in hydrogels and high technology papers.…”

ObstractCellulose nanocrystals (CNC) and nanofibrils (CNF) were obtained by acid hydrolyzis and mechanical treatment, respectively, of cellulosic fibers from paper. Additionally, surface modification was performed for CNC by neutralization (NaOH) and oxidation (TEMPO). The thermal stability, surface properties and rheological behavior of these nanomaterials were compared. A clear difference in CNC surface was found upon neutralization and oxidation treatments, leading to distinct thermal behaviors. Optical and rheological properties were found to be predominantly by the particles size, being strongly affected by inertial effects.

“…In fact, straw is rich in silica (SiO2) and lignin, which prevent it from breaking down when added to the soil before the next crop is planted. As matrix material fibers, processed rice straw is utilized in the creation of the composite [9][10]. The complete rice straw fiber is made up of the rice husk, leaf sheath, straw leaf blade, straw stem and knot, and straw root.…”

Rice straw and rice husk fibers (RS/RH) reinforced polymer-based composites have theability to conserve wood and petroleum resources. As natural filler, rice straw and rice husk offer asustainable material for the production of polymer-based composites. The application ofbiocomposite limits the burning of straw at the root and may further enhance the socioeconomicstatus of farmers and rural populations. This review mainly focuses on five different weightpercentage of reinforced RS and RH fiber content (5%, 10%, 15%, 20% and 25%) in polymercomposites. Nowadays, Epoxy, polyurethane, polyester, PVA, PLA and polyethylene are beingused as matrix material in polymer composites. This paper holds good with understanding themechanical properties, pretreatment methods and offer important insight into potential uses ofpolymer composites with biodegradable reinforce fiber.

Looking for alternatives to promote the diversification of the Brazilian energy grid through the utilization of renewable fuels, this forecasting study evaluates the potential to generate thermal energy from lignins extracted of several crops in the period 2015–2021. The estimates were carried out taking into account two biomass particle size distributions (ranged between 105–500 µm and 1000–2000 µm) and two extraction methods (Klason and Willstatter) to assess the lignin yields obtained from five well‐known Brazilian crops. Results revealed that lignins obtained from the sugarcane bagasse, wood chips, and corn straw would have the highest potential to provide thermal energy when data of lignin yields, higher heating values, and crops production are considered. The estimate suggests that in 2021 this alternate fuel could supply more than 1320 × 106 GJ yr−1 of thermal energy from the five crops analyzed, owing to the expected increase of the acreage and production for the most crops studied here in the next years. Recognizing that more studies are still needed, mainly in terms of economic feasibility, results of this work warn about possible additional benefits in developing the large‐scale production of second‐generation ethanol (via hydrolysis), in which lignin fractions from several crops could be separated and recovered for using them as new energy resource. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 717–722, 2017
