“…Nagarajan and co‐workers [ 215 ] have incorporated 15 wt% of cellulose extracted from Cocos nucifera var Aurantiaca Peduncle into epoxy composites that presented a great increase over tensile strength, from 32.5 MPa for the polymer to 52.5 MPa for the composites. Moreover, Perumal and co‐workers [ 229 ] have incorporated 5 wt% of cellulose extracted from rice straw into PVA/chitosan composites, which showed an increase from 56.1 MPa for the polymer to 98.1 MPa after the incorporation of waste‐based cellulose.…”

The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…PVA is also non-toxic on the human body and can be used to manufacture medicine cachets, drug delivery systems, barrier materials, membranes, and yarn for surgery [24][25]. The use of PVA for environmentally friendly food packaging began widely used due to several advantages of PVA, including strength, transparent, lightweight, non-toxic, heat-stable, antimicrobial, and good elasticity [26][27][28].…”

This paper presents an experimental study of addition of cellulose nanofibers (CNF) extracted by the chemical-ultrasonication process from agave cantala leaf plants in the matrix of polyvinyl alcohol (PVA). Combining these materials produce the nanocomposite film with a thickness of 30 μm. The nanocomposite characteristic was investigated by the addition of CNF (0, 2, 5, 8, and 10 wt%) in PVA suspension (3 wt.%). PVA/CNF nanocomposite films were prepared by a casting solution method. The fibrillation of fibers to CNF was analyzed using Scanning Electron Microscopy and Transmission Electron Microscopy. The nanocomposite film functional group's molecular chemical bond and structural analysis were tested using Fourier Transform Infrared and X-ray diffraction. The PVA/CNF nanocomposite film has significant advantages on the ultraviolet barrier, thermal stability tested by Differential Scanning Calorimetry and Thermogravimetric Analyzer, and tensile strength. Overall, the optimal addition of CNF is 8 wt.% in matrix, resulting in the highest crystallinity index (37.5%), the tensile strength and elongation at break was an increase of 79% and 138%, respectively. It has good absorbing ultraviolet rays (82.4%) and high thermal stability (365 o C).

“…They observed a significant increase of tensile strength and tensile modulus of 38.1% and 8.91%, respectively. Other authors [30] used the same reinforcement based on NCC, extracted from rice straw, by the solvent casting of polyvinyl alcohol (PVA)/chitosan (CS) with up to 5 wt % NCC. With the addition of 5 wt % NCC, the tensile strength of PVA/CS film increased from 56.12 MPa to 98.15 MPa, and the elastic modulus from 892 MPa to 1764 MPa.…”

Bags used to protect and accelerate the ripening of bananas are a clear example of the environmental problem of packaging waste. Small pieces of these non-biodegradable bags are frequently disposed on the soil by accident (environmental conditions and poor handling during the harvest) and remain there for years. This work focuses on the development of protective biodegradable bags reinforced with banana fiber, obtained from waste of the banana plants, thus promoting a circular economy and a more environmentally friendly process. To achieve this, different bio-based composites were tested (processability) by compounding extrusion (biopolymer and banana fiber with different process steps) and blown film extrusion. The bags produced were tested in field and sequentially improved in three generations of biofilms. The results showed that the maximum processable fiber content was 5 wt %. Additionally, the micronizing of the compounds was crucial to simplify the blown film extrusion and improve the smoothness of the bags (scratches avoidance on the banana surface). The final bags (Mater-Bi biopolymer, 5% combed and sieved banana fiber, and 2.5 wt % TiO2 for ultraviolet light filtration), performed better than the conventional ones (faster maturing, i.e., earlier harvest, and easier handling) and fulfilled the biodegradability, composting and ecotoxicity test requirements.
