“…A peak at 1729 cm −1 is attributed to the stretching band vibration of esters. In contrast, there is only one peak at 2890 cm −1 associated with C-H stretching vibrations in the NCC 6 . Figure 7B shows the FTIR spectra of the material remained in suspension after the second H 2 SO 4 incubation, showing peaks corresponding to cutins, along with remaining traces of nanocellulose, as showed by the peak at 884 cm −1 .…”

“…6B and Supplementary Table S1 ). On one hand, pineapple peels contain cutin, lignin, hemicellulose and proteins, volatile compounds which are expected to degrade between 135 °C and 600 °C 6 , 25 , 26 ; on the other hand, the silicon derivate compounds can be assigned to the 12.9 wt.% residue obtained from the pineapple peel according to the EDX, along with highly condensed aromatic structures formed by residual carbon 26 . A weight loss in the enriched BMRS solid fraction at temperatures lower than 450 °C was observed, which could occur due to the nanocellulose attached to the particles and other carbon based compounds, according to the EDX analysis.…”

“…S1 . Briefly, the ground pineapple peels were incubated in NaOH to remove the lignin and hemicellulose, then bleached in NaClO, before incubating in HCl to hydrolyze the cellulose and to obtain microcellulose 6 . Between each step, the product was thoroughly rinsed with water until neutral pH, and the solid was recovered by centrifugation at 13000 rpm.…”

Silica in plant tissues has been suggested as a component for enhancing mechanical properties, and as a physical barrier. Pineapples present in their shell and bracts rosette-like microparticles that could be associated to biogenic silica. In this study, we show for the first time that silica-based microparticles are co-purified during the extraction process of nanocellulose from pineapple (Ananas comosus). This shows that vegetable biomass could be an underappreciated source, not only for nanocellulose, but also for a highly valuable sub-product, like 10 µm biogenic rosette-like silica-based microparticles. The recovery yield obtained was 7.2 wt.%; based on the dried initial solid. Due to their size and morphology, the microparticles have potential applications as reinforcement in adhesives, polymer composites, in the biomedical field, and even as a source of silica for fertilizers.

“…Acid hydrolysis of cellulose is the most common process for obtaining NCFs [ 43 ], as fractions containing amorphous material can be hydrolyzed with HCl and sulfuric acid, while those containing crystalline cellulose are typically recovered by centrifugation [ 44 , 45 ]. NCFs have been isolated from banana peel using different processes, involving alkaline treatment and bleaching, followed by acid hydrolysis with sulfuric acid and high-pressure homogenization [ 46 ].…”

On a worldwide scale, food demand is increasing as a consequence of global population growth. This makes companies push their food supply chains’ limits with a consequent increase in generation of large amounts of untreated waste that are considered of no value to them. Biorefinery technologies offer a suitable alternative for obtaining high-value products by using unconventional raw materials, such as agro-industrial waste. Currently, most biorefineries aim to take advantage of specific residues (by either chemical, biotechnological, or physical treatments) provided by agro-industry in order to develop high-value products for either in-house use or for sale purposes. This article reviews the currently explored possibilities to apply biorefinery-known processes to banana agro-industrial waste in order to generate high-value products out of this residual biomass source. Firstly, the Central and Latin American context regarding biomass and banana residues is presented, followed by advantages of using banana residues as raw materials for the production of distinct biofuels, nanocellulose fibers, different bioplastics, and other high-value products Lastly, additional uses of banana biomass residues are presented, including energy generation and water treatment.

Contamination of the ecosystem from plastics is the most prominent concern of current times. Natural materials like plant-based fibers from cellulose, hemp, sisal, etc., are preferred and being looked upon as better alternatives.Cellulose, being biocompatible and biodegradable, possesses appreciable properties. Its nanoscale form, called as nanocellulose, can be extracted from agricultural residue and lignocellulosic biomass through different chemomechanical techniques. Chemical methods include alkaline treatment, chemical bleaching, acid hydrolysis, and TEMPO mediated oxidation, whereas highpressure homogenization, grinding, cryogenic crushing, and ultrasonication are the mechanical methods used for the isolation and extraction of nanocellulose. This review presents a comprehensive analysis of various processing and extraction methods used for nanocellulose. The review also brings an insight into nanocellulose-polymer based composites including their mechanical, biological, thermal, and physical properties. A detailed discussion on nature, morphology, size, and other parameters through different characterization techniques is also presented in this review. Finally, the applications of nanocellulose in biotechnology, biomedical, mechanical, material science, chemical, and electronics engineering have also been discussed. K E Y W O R D Sbio-composites, characterization, chemo-mechanical methods, extraction, nanocellulose | INTRODUCTIONUrge to go green has led to a shift toward eco-friendly or green materials. This approach aims at reducing the emissions of greenhouse gases to safeguard the environment at a global level. Eco-friendly and naturally occurring materials are being mostly focused for such purposes. This is done in order to reduce the dependence and for the replacement of synthetically available materials. The naturally occurring materials offer several advantages like sustainability, low cost, better resistance toward wear, low toxicity, high modulus of elasticity, and large specific area with better mechanical and biological properties. The advantages of incorporating the use of eco-friendly or green materials are shown in Figure 1.Natural fibers obtained from plants and other sources are being used to develop materials with greater interests and scope. Widely used natural fibers include cotton, flax, silk, sisal, jute, and alpaca, etc. Composites made from natural fibers are called as bio-composites. The fibers can be utilized as a segment of composite materials, where their orientation impacts the overall properties. In these
