“…The tensile stress at break for the nanocomposites prepared from products A and B at 5 wt% was also noticeably enhanced compared to PVA control, confirming previous reports. 9,13,44,45 Tensile stress at yield increased markedly relative to the control at both fibre addition levels (Table 5), again demonstrating the high reinforcing efficiency of the cellulose nanofibres. This results from the high surface area of the NFC and extensive hydrogen bonding with the PVA matrix leading to the formation of a rigid network.…”

This study has demonstrated biorefining steps for ryegrass and silage at a pilot scale to extrude fibre cake for the production of nanofibrillated cellulose (NFC), a potentially green biomaterial for replacing conventional fillers in the manufacture of polymer composites. Further treatments of processed ryegrass fibres with mechanical shearing, microfluidising, hydrochloric acid (HCl)/ sulphuric acid and a four stage {ethylenediaminetetra-acetic acid, sodium hydroxide, sodium hypochlorite and HCl} hydrolysis yielded 43.8, 36.1, 25.6 and 39.8 kg t 21 DM of NFCs respectively. The NFCs were characterised using microscopy, X-ray diffraction, dynamic light scattering, spectroscopy and thermogravimetry. The NFC had diameters from 3.0-9.1 nm and length 308 nm-4.6 mm. NFC-polyvinyl alcohol composites containing NFC (5 wt%) exhibited enhanced Young's modulus and thermal stability by factors of 2.5 and 2 respectively compared with control. The mass, energy, water and chemical balances of the four process steps were assessed to evaluate technical feasibility and also to provide baseline production data for scaling up. The microfluidised product has been identified as the best NFC product, but production cost needs to be reduced.

Nanocomposites (NCS) are advanced materials consisting of a matrix material infused with nanoscale particles or fillers, exhibiting exceptional properties such as high conductivity, strength, reactivity, and thermal/electrical characteristics. This article provides an overview of nanocomposites, including their properties, preparation methods, and diverse applications across industries like aerospace, automotive, biomedical, energy, water purification, and environmental bioremediation. Various techniques for nanocomposite preparation, such as electrospinning, are discussed along with their potential for producing tailored materials with enhanced properties. Challenges and future directions in nanocomposite research, including scalability and cost considerations, are highlighted, along with emerging trends and prospects in nanotechnology applications.

“…Thus, biological decomposition of farm waste is the most important and effective way to remove these compounds from the environment [22][23][24][25]. But most of the farm waste is utilized by burning it in the farm leading to loss of economical soil microflora, therefore farm waste can be used to recycle the nutrients by way of efficient in-situ composting [26][27][28][29].…”

The most important component of the greatest material flow in the biosphere is the microbial consumption of cellulose. Despite the abundance of cellulase manufacturers, there aren't enough microorganisms that can effectively create enough of the enzyme to effectively break down cellulose into fermentable compounds. Despite the fact that bacteria have a very high level of natural variety and the potential to manufacture stable enzymes, little attention has been paid to their ability to produce cellulase. The present study aimed at the isolation and selection of cellulose degrading bacteria isolated from different samples for agriculture waste decomposition. Bacterial cultures were applied on agriculture waste material comprising soybean straw, pigeonpea straw; wheat straw and cotton stalk to investigate their percentage loss in weight. Among all the cultures, CDB 19 has shown the highest weight loss of the substrate (99.99%) followed by CDB 20 (99%), CDB5 (94.2%), CDB2 (92.8%) and CDB14 (88.6%). It was also observed that maximum weight loss of cotton straw (99.99%) was recorded by mixed culture followed by Pigeonpea straw and Soybean straw, while Wheat straw recorded minimum weight loss at 60 days of decomposition.
