“…Cellulose aerogels can be obtained from pineapple leaves, sugarcane bagasse or coconut shells. Because of numerous hydroxyl groups on the cellulose chains of pineapple leaf fibers, PVA binder is used to create the hydrogen bonding between the fibers in the first pineapple aerogels developed by Luu et al [ 95 ] and Do et al [ 80 ] (Fig. 7 a).…”

“…Aerogels prepared from cellulose-rich waste are biodegradable, easy to be functionalized for different uses, and inexpensive due to the abundance of raw materials [5]. Do et al developed cellulose aerogels from pineapple agricultural waste that had excellent properties for applications such as sound insulation, thermal insulation, as well as oil and organic solvent adsorption [12,13]. Later generations of cellulose aerogel have been developed with the addition of reinforcements, for example, polymers, metals, and inorganic compounds to obtain novel aerogel composites that not only keep aerogel-like properties but also have improved compressive strength, elasticity, toughness, and high module−to−volume ratio [14,15].…”

In a world where demands for freshwater are ever-growing, wastewater remediation becomes a global concern. Especially, water, which is contaminated by oil, dyes, poses challenges to the management of water resources. The development of innovative processes for wastewater treatment is still a major obstacle. With regard to its fast removal rate and environmental compatibility, cellulose aerogel composites are recently considered as a potential contributor for water remediation. In this study, cellulose aerogel composites are fabricated using the sol-gel method from two-agroindustrial wastes: pineapple leaf fibers and cotton waste fibers in alkali-urea solution followed by freeze-drying. The prepared cellulose aerogel composites are extremely lightweight with a low density (0.053−0.069 g.cm −3 ) and high porosity of nearly 95%. It is worth noting that the mechanical strength of the cellulose aerogel composites is remarkably improved with their Young's modulus increasing by 5-9 times compared to that of the previous aerogel composites using polyvinyl alcohol as a binder. The as-synthesized aerogel composites are directly applied to adsorb cationic methylene blue and exhibit a maximum adsorption uptake of 34.01 g.g -1 .The methyltrimethoxysilane-coated cellulose aerogel composites also show their ability to deal with oil pollution with a maximum oil adsorption capacity of 15.8 g.g −1 within only 20 sec. Besides the oil removal, our developed cellulose aerogel composites have demonstrated their capability in treating dye-contaminated wastewater for the first time based on their evidenced ability to eliminate methylene blue.

“…13 Industrially, the fruit is used as a resource for the manufacture of pulp, syrup, jam, and bottled juices, generating 55-70% of waste. 14 Pineapple waste contains various valuable substances for the development of new and emerging technologies, nutraceuticals, food, adsorbents, and aerogels production [15][16][17] In addition to its availability, pineapple waste is also attractive in terms of its mechanical properties, which should be good for plastic reinforcement. 18 However, this waste has hydrophilic characteristics, which can compromise the interfacial adhesion between fiber and matrix.…”

This study proposes that green composites using recycled plastic bags (PEr) extruded with pineapple fiber waste (PR) from a juice industry to increase pineapple’s economic value stimulate practices that prioritize recycling and development of new materials. PEr composites were prepared using PR as a filler, using different fiber loadings of 5, 10, and 15 wt%, and the use of a coupling agent, prepared via extrusion and injection molding. The samples were investigated by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis, inflammability, mechanical tests (tensile, impact, and shore hardness), scanning electron microscopy, and water absorption tests. FTIR results demonstrated that the addition of PR to the PEr caused a decrease in the characteristic bands of neat PEr, evidencing the chemical interactions. Thermal analysis showed that the addition PR decreased composites' thermal stability, causing relatively higher percentages of char compared to neat PEr, which increased the burning rate of composites, except for PEr/15PR and PEr/5PR-C. Green composites exhibited higher tensile modulus and hardness than PEr, but the impact tests presented a decrease in the fibers' addition to the PEr due to the reduction of toughness and resilience. SEM of fractured surface composites presented microcracks, voids, and fibers breakage in the interface. The composites showed low water absorption (up to 0.804%). The coupling agent’s use presented a low influence on the mechanical and thermal properties and a slight decrease in water absorption. These results demonstrate o potential of the reuse of plastic bags and industrial waste for green composites.
