“…Cellulose, as a biobased polymer, appears at high frequency in these documents, mostly due to being used as a replacement of synthetic polymers in applications such as electronics, composites, applications in the biomedical field, sustainable biomaterials, textiles, and to remove microplastics from the environment, etc. [28][29][30][31][32][33] Cellulose is also considered a microplastic in some studies, especially modified or regenerated cellulose in the form of rayon or cellophane particles.

The growing usage of plastics in their various forms and applications has resulted in an exponential increase and spread of microplastics throughout the environment. We present a review based on a comprehensive analysis of the CAS content collection on the awareness of the underlying detrimental effects of several types of microplastics. The sources of this microplastic pollution are derived from its direct production or the degradation of macroplastics and include items such as personal care products, synthetic textile fibers, and rubber tires. The most frequent polymers observed in microplastic pollution are polyethylene, polystyrene, polypropylene, polyethylene terephthalate, and polyvinyl chloride. These plastics are frequently mixed or combined with chemical additives such as phthalate and polybrominated biphenyls and are prevalent throughout the atmosphere, water, and in food. When these plastic pollutants are ingested or inhaled, adverse health effects are likely to result. This review reports the current scientific literature on microplastics and aims to analyze the current knowledge regarding their toxicology and potential solutions for the management and remediation of this type of plastic pollution.

“…Cotton fibres are commonly used for surgical clothing, bedding, and medical uniforms; viscose fibres are used for medical caps, masks, diapers, and handkerchiefs. Man-made fibres such as polyester fibres are used for masks, surgical headgear, and blankets; polyamide fibres are used for surgical socks; polypropylene fibres are used for protective clothing, liners, and diapers; and polyethylene fibres are used for surgical drapes [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”

The demand for hygienic nonwovens has increased, especially since 2020. As expected, the market for nonwovens showed an increase during the COVID-19 outbreak, especially in the medical and hygienic nonwovens sector. The aim of this study is to analyse the influence of the permeability properties of hygienic nonwovens that have been mechanically, chemically, and thermally bonded. Hygienic nonwovens are lightweight (from 20 to 120 g/m2), produced by carding (roller carding), and are bonded using three different bonding processes (mechanical, thermal, and chemical). Hygienic nonwovens are intended for protective clothing in hospitals. For the experimental part, the seven different nonwovens used for hygienic purposes were produced using the dry laying process. The samples were produced in Tosama, a factory for sanitary supplies. The research results show that the nonwoven bonding processes have a significant influence on the structural, mechanical, and permeability properties.

“…8 Biobased and faster biodegrading nonwoven wet wipes, based for example on the abundant biopolymer cellulose, would be an attractive alternative. 9 Cellulose gels are environment friendly and good adsorbents of fluids with potential to be molded or 3D printed into different sizes and shapes. 10−12 The commercial water-soluble cellulose derivatives, such as hydroxyethyl cellulose (HEC) and carboxymethylcellulose (CMC), can be easily modified by, e.g., methacrylation to provide groups that can be utilized for the fabrication of more stable covalently cross-linked gels.…”

Cellulose-derived materials could offer more sustainable alternatives for current single-use hygiene articles produced from nondegradable fossil-based polymers. We successfully fabricated light processable methacrylated carbon dot-hydroxyethyl cellulose resins and illustrated potential applications in dye adsorption, antibacterial gels, and wet wipes. Carbon dots were first produced by microwave-assisted hydrothermal carbonization and the oxidation of cellulose. The obtained carbon dots and hydroxyethyl cellulose were in situ methacrylated to composite resins, which could be cured to gels in a mold or processed to 3D structures with digital light processing 3D printing. The cured gels had an adequate gel content of 80–84% and high swelling degree up to 350% in binary mixtures of water and dimethyl sulfoxide. Furthermore, the gels were effective dye-adsorbents, and they retained some of the antibacterial properties of nonmodified hydroxyethyl cellulose as evaluated by the disc diffusion method. While the gels could still be recovered after 60 days of soil burial at room temperature, clear sign of degradation and opening of the cross-linked structure were observed by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Finally, a potential wet wipe was fabricated by laminating the produced gel between two electrospun cellulose acetate mats.
