“…Although the content variation in this sugar type was only 4 % among the materials, it is possible to develop pentose-richer cultivars to produce 5-carbon materials for xylitol and furfural production or for special ethanol fermentations from these sugars. Reddy and Yang (2005) also found similar hemicellulose contents (19 to 24 %).…”

Sugarcane (Saccharum spp.) is an efficient and sustainable alternative for energy generation compared to non-renewable sources. Currently, during the mechanized harvest process, the straw left in the field can be used in part for the second generation ethanol and increasing the electric energy production. Thus, this study aimed to provide information on the potential for residual biomass cultivars of sugarcane cropping system. This study provides the following information: yield of straw, depending on the calculated leaf area index and the number of tillers per linear meter; primary energy production of several sugarcane genotypes; contribution of dry tops and leaves; biomass yield; and evaluation of fiber, cellulose, hemicellulose and lignin. Preliminary results obtained by researchers of the State of São Paulo, Brazil, and reCviews related studies are presented. The results suggest that the production of sugarcane straw content varies according to the cultivars; the greater mass of sugarcane straw is in the top leaves and that the potential for the crude energy production of sugarcane per area unit can be increased using fiber-rich species or species that produce more straw. The straw indexes was shown to be a good indicator and allow the estimation of straw volumes generated in a sugarcane crop. The cellulose, hemicellulose and lignin composition in sugarcane is distinct among varieties. Therefore, it is possible to develop distinct biomass materials for energy production and for the development of sugarcane mills using biochemical processes and thermal routes.

“…Wheat gluten and PLA fibers were heated in water at 90°C for 60 min in various pH (3,5,7,9, and 11) conditions to test their stability. The hot water treated fibers were tested and compared to the untreated controls for the changes in tensile properties.…”

“…[7][8][9][10][11] Similarly, attempts have also been made to use plant proteins such as soybeans, corn, and peanut and also milk proteins (casein) for fiber production. Reports are available on the commercial scale production of fibers from these sources during the 1930s and 1940s.…”

Protein fibers with mechanical properties similar to those of wool and better than those of soyprotein and zein fibers have been produced from 100% wheat gluten. Wheat gluten is a low cost, abundantly available, and renewable resource suitable for fiber production. A simple production method has been developed to obtain high-quality wheat gluten fibers, and the structure and properties of the fibers have been studied. Wheat gluten fibers have breaking tenacity of about 115 MPa, breaking elongation of 23%, and a Young's modulus of 5 GPa, similar to those of wool. Wheat gluten fibers have better tensile properties than soyprotein-and casein-based biomaterials. In addition, the wheat gluten fibers have resistance similar to that of PLA fibers to water in weak alkaline and slightly lower resistance in weak acidic conditions at high temperatures.

“…Reduction in moisture uptake by the treated fiber may be due the partial removal of lignin and hemicellulose component of fiber by chemical treatment. Also, in all natural cellulose fibers, a hollow cavity called lumen exists in the unit cell of the fibers 48 . The hollow cavity generates more pathways for water to start diffusing into the fiber.…”

Environmentally valuable composites would be made by replacing synthetic fibers with various types of natural cellulose fibers. The most significant factor in finding good fiber reinforcement in the composite is the strength of the bond between matrix polymer and fiber. Due to the presence of hydroxide and other polar groups in various constituents of natural fiber, the moisture absorption is high which leads to poor wettability and weak interfacial bonding between fibers and the more hydrophobic matrices. Therefore, it is necessary to impart hydrophobic nature to the natural fibers by suitable chemical treatments in order to develop composites with better mechanical properties. In the present work, the effect of esterification on moisture absorption of single abaca fiber has been investigated. It was observed that the esterification process drastically reduced the moisture uptake of fibers. Acrylic acid treated abaca fiber showed about 32.87, 32.53, 50.76 and 39.01% lower moisture absorption than untreated fiber in pond water, river water, borewell water and sea water respectively.
