“…Different agricultural and food wastes have been used as a carbon source for the production of BNC [93][94][95][96]. With respect to the use of residual biomass from the banana value chain, rotten banana [83], as well as banana peel [44,81], have been used as a carbon source in the fermentation stage to obtain this biopolymer.…”

Bananas are one of the most important crops worldwide. However, a large amount of residual lignocellulosic biomass is generated during its production and is currently undervalued. These residues have the potential to be used as feedstock in bio-based processes with a biorefinery approach. This work is based on the valorization of banana leaf and has the following objectives (i) to determine the effect of certain physical and environmental factors on the concentration of glucose present in banana leaf extract (BLE), using a statistical regression model; (ii) to obtain Bacterial Nanocellulose (BNC), using BLE (70% v/v) and kombucha tea as fermentation medium. In addition, the physicochemical properties of BNC were evaluated by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermogravimetric analysis (TGA). The results indicate that storage time, location, leaf color, and petiole type are factors related to BLE concentration, which is reduced by approximately 28.82% and 64.32% during storage times of five days. Regarding BNC biosynthesis, the results indicate that the highest yield, 0.031 g/g, was obtained at 21 days. Furthermore, it was determined that the highest production rate was 0.11 gL−1h−1 at 11 days of fermentation. By FTIR, it was determined that the purification step with NaOH (3M) should be carried out for approximately two hours. This research supports the development of a circular bioeconomy around the banana value chain, as it presents a way of bioprocessing residual biomass that can be used to produce bioproducts.

“…Another alternative to produce nanocellulose is through the use of microorganisms such as Gluconacetobacter xylinus or Medusomyces gisevii . Banana residues are used as a food source for the bacteria that produce bacterial nanocellulose (BNC) when the organic substrate (sugar, fructose, glycerol) is polymerized during cultivation [ 155 , 156 ].…”

Banana is a fruit grown mainly in tropical countries of the world. After harvest, almost 60% of banana biomass is left as waste. Worldwide, about 114.08 million metric tons of banana waste-loss are produced, leading to environmental problems such as the excessive emission of greenhouse gases. These wastes contain a high content of paramount industrial importance, such as cellulose, hemicellulose and natural fibers that various processes can modify, such as bacterial fermentation and anaerobic degradation, to obtain bioplastics, organic fertilizers and biofuels such as ethanol, biogas, hydrogen and biodiesel. In addition, they can be used in wastewater treatment methods by producing low-cost biofilters and obtaining activated carbon from rachis and banana peel. Furthermore, nanometric fibers commonly used in nanotechnology applications and silver nanoparticles useful in therapeutic cancer treatments, can be produced from banana pseudostems. The review aims to demonstrate the contribution of the recovery of banana production waste-loss towards a circular economy that would boost the economy of Latin America and many other countries of emerging economies.

“…From the thorough study of the literature, it is found that adsorption study is the best practice to remove lead ion concentration. The adsorbent is made up of agricultural waste such as poplar, maize, rice straw wheat straw, cotton straw, cotton stalk, rice husk, coconut core, etc (Abdullah et al, 2021;Mehanny et al, 2021;S. Yu et al, 2021).…”

In recent years, there is a rapid growth in nanotechnology. This study's goals were to first modify the nanocellulose surface using titanium dioxide (TiO2) to become nanocomposite and then determine how well a nanocomposite adsorbs lead ions from water. Nanocellulose was synthesized from the cotton straw residue using chemical and mechanical methods. The layer of titanium dioxide is coated on nanocellulose. The nanocomposite of titanium dioxide was characterized by using FTIR, XRD, and FESEM. The results showed that Ti-O-Ti bonding was observed at 505.02 cm-1. The structure of the nanocomposite is much more disordered and irregular. The presence of a 65 % anatase phase and 32 % rutile phase is found in the crystalline particle of the nanocomposite. The crystal structure of the nanocellulose and nanocomposite is found with particle sizes 18 nm and 83 nm. The nanocomposite was utilized to absorb lead ion concentration from the aqueous solution. The adsorption capacity of nanocomposite was analyzed with kinetics, isothermal and thermodynamic models. Kinetic parameters show that the pseudo 2nd order (R2=0.98) nonlinear kinetic model is the best fitted and in isotherm model Langmuir (R2=0.99), Elovich (R2=0.99) and Baudu (R2=0.99) isotherms were well suited for the adsorption of lead ions. Thermodynamic parameters resulted in Gibbs free energy decreasing with temperature.
