“…The babassu palm already has a significant history of applications, as mentioned earlier, including the use of its fibers in composites for engineering applications. In addition to the analysis of the properties of the fiber in isolation [194][195][196], the investigation of composite materials using this fiber as a reinforcing agent enables its application in various engineering fields while maintaining a sustainable approach to plastic materials.…”

“…An example is highlighted in the work of Furtado et al [196], in which the authors produced low-density polyethylene (LDPE) composites reinforced with babassu fibers at concentrations ranging from 5 to 20 wt.%. They conducted a comprehensive analysis of the mechanical and photodegradative properties, simulating solar and ultraviolet (UV) radiation conditions, aiming for potential use in biodegradable plastic bags.…”

The Amazon rainforest, spanning multiple countries in South America, is the world’s largest equatorial expanse, housing a vast array of relatively unknown plant and animal species. Encompassing the planet’s greatest flora, the Amazon offers a tremendous variety of plants from which natural lignocellulosic fibers (NLFs) can be extracted. In this century, NLFs, which have long been utilized by indigenous populations of the Amazon, have garnered interest as potential reinforcements for composites, whether polymer- or cement-based, in various technical applications such as packaging, construction, automotive products, and ballistic armor. A comparison with synthetic materials like glass, carbon, and aramid fibers, as well as other established NLFs, highlights the cost and specific property advantages of Amazon natural fibers (ANFs). Notably, the sustainable cultivation and extraction of ANFs, as alternatives to deforestation and livestock pasture, contribute to the preservation of the Amazon rainforest. This review article provides a comprehensive examination of recent studies directly related to ANF-reinforced polymer matrix composites. The specific advantages, proposed applications, and reported challenges are highlighted, shedding light on the potential of these unique natural fibers.

Tobacco use is dangerous to health and the environment. Despite the numerous measures taken to combat the adverse effects of tobacco, fruitful results are yet to be achieved. Nicotine is the primary psychoactive (and highly addictive) chemical component in tobacco. This study aimed to lower the nicotine content and detoxify bidis (a more harmful tobacco product compared to cigarettes). We subjected the bidi packets to 2–6 µm mid-infrared (midIR) light generated by a specially designed pocket-sized atomizer. The smoke from such mid-IR-treated bidis blown over animate and inanimate objects was non-irritating and harmless. Spectroscopic studies revealed that the applied 2–6 µm mid-IR exerted molecular-level changes and resulted in chemical compound transformations, thus lowering the nicotine content in the bidis. Trials with smokers demonstrated that the mid-IR-treated bidis were more desirable to smoke and also retained smoking pleasure and satiety. Thus, the 2–6 µm mid-IR light can detoxify the bidis and represents a safer way for smoking than attempting complete cessation, which is highly challenging for smokers.

“…A pretreatment or surface modification of the fiber surface must be added during processing to increase fiber-matrix adhesion. Various techniques have been devised to fix the surface of the fibers, including chemical and photochemical processes [8,9]. Chemicals can activate the hydroxyl group in cellulose to cause the polymer to take on the desired properties.…”

Unidirectional polypropylene (PP) composites reinforced with bhendi fibers (BFs) were produced after BFs were subjected to UV light at different intensities. Mechanical parameters such as tensile strength, tensile modulus, and impact strength of irradiated BF/PP composites significantly improved compared to non-irradiated counterparts. To enhance their properties, different amounts of 2-hydroxyethyl methacrylate (HEMA) in methanol were applied to the surfaces of irradiated BFs, and UV light was subsequently used to cure them. Tensile strength, tensile modulus, and impact strength values rose by 32%, 20%, and 37%, respectively, after the optimized grafting and mechanical properties. Alkali solutions were applied to BFs for 30 minutes at varying temperatures and concentrations to alter their surfaces. Then, using the same UV light, BFs were photocured after being grafted with an optimal HEMA solution. Of all the composite samples treated with 10% HEMA, the alkali + 10% HEMA-treated composites exhibited superior mechanical performance. SEM studies exhibited that the optimized alkali with 10% HEMA treated composite had better dispersion than the 10% HEMA treated composite. Water absorption was significantly lower in the treated than in the untreated sample. According to weather studies, the treated specimens may have less loss tensile characteristics than the untreated specimens.
