“…In membrane preparation and adsorption efficiency, the electrospun polyacrylonitrile (PAN) nanofiber membrane was functionalized with CS and proteins for use in the treatment of dye-containing WW. 53 The PAN nanofiber membrane was subjected to alkaline hydrolysis, before being grafted with CS and subsequently the proteins from chicken egg white. The resultant nanofiber membrane was comprehensively characterized using TGA, FT-IR spectroscopy, and SEM.…”

“…Some traditional methods, such as adsorption, photocatalytic degradation, chemical oxidation, coagulation/flocculation, and biological treatment, are implemented, but all these highlighted methods have some limitations, such as high energy input in photocatalysis, side stream development in biological treatments, recycling/regeneration in adsorption, and low removal efficiency in coagulation/flocculation, etc. Another challenge is imperfect targeting of nano-pollutants (e.g., dyes, heavy metal ions, toxins, and nanosized living organisms such as bacteria and viruses) [ 6 , 7 ].…”

Textile industries currently face vast challenges for the active removal of colored wastewater. Indeed, sustainable, recyclable, and green approaches are still lacking to achieve this aim. Thus, the present study explored the utilization of highly functional, green, recyclable, fully bio-based, and cost-effective composite membranes from post-consumer cotton fabrics and palm waste for wastewater treatment purposes. Highly functional cellulose nanofibers (CNF) were produced from waste cotton fabrics and filter paper using an acid hydrolysis technique. The yield of nanofibers extracted from waste cotton fabrics and filter paper was 76.74 and 54.50%, respectively. The physical, chemical, and structural properties of nanofibers were studied using various advanced analytical techniques. The properties of isolated nanofibers were almost similar and comparable to those of commercial nanofibers. The surface charge densities were −94.0, −80.7, and −90.6 mV for the nanofibers of palm waste, cotton fibers, and filter paper, respectively. After membrane fabrication using vacuum and hot-pressing techniques, the characteristics of the membrane were analyzed. The results showed that the average pore size of the palm-waste membrane was 1.185 nm, while it was 1.875 nm for membrane from waste cotton fibers and filter paper. Congo red and methylene blue dyes were used as model solutions to understand the behavior of available functional groups and the surface ζ-potential of the membrane frameworks’ interaction. The membrane made from palm waste had the highest dye removal efficiency, and it was 23% for Congo red and 44% for methylene blue. This study provides insights into the challenges associated with the use of postconsumer textile and agricultural waste, which can be potentially used in high-performance liquid filtration devices for a more sustainable society.

“…Chitin can be extracted via chemical or biotechnological processes from seafood waste such as shrimp, lobster, and crayfish shells [ 7 , 8 , 9 , 10 ]. Chitosan has been extensively studied as a promising biopolymer to be used in active packaging films, coatings, and other industrial applications due to its antioxidant and antimicrobial properties [ 11 , 12 , 13 , 14 , 15 , 16 ]. Its poor mechanical properties can be enhanced by blending with other polymers [ 17 , 18 ] biopolymers [ 19 , 20 , 21 ] and/or incorporating nano-reinforcements such as nanoclays to give promising chitosan-based biopolymeric nanocomposite gels ready for film preparation [ 22 ].…”

The concept of this study is the replacement of previous fossil-based techniques for food packaging and food shelf-life extension, with novel more green processes and materials following the spirit of circular economy and the global trend for environmentally positive fingerprints. A novel adsorption process to produce thymol-halloysite nanohybrids is presented in this work. The high dispersion of this thymol-halloysite nanostructure in chitosan biopolymer is one of the goals of this study. The incorporation of this biodegradable matrix with poly-vinyl-alcohol produced a very promising food-packaging film. Mechanical, water-oxygen barrier, antimicrobial, and antioxidant properties were measured. Transparency levels were also tested using a UV-vis instrument. Moreover, the developed films were tested in-vivo for the preservation and the extension of the shelf-life of kiwi fruits. In all cases, results indicated that the increased fraction of thymol from thyme oil significantly enhances the antimicrobial and antioxidant activity of the prepared chitosan-poly-vinyl- alcohol gel. The use of the halloysite increases the mechanical and water-oxygen barrier properties and leads to a control release process of thymol which extends the preservation and the shelf-life of kiwi fruits. Finally, the results indicated that the halloysite improves the properties of the chitosan/poly-vinyl-alcohol films, and the thymol makes them further advantageous.
