Advanced and Smart Technology for Sustainable Management of Microfiber Waste

Microfibers are abundantly found in nature as contaminants and have harmful environmental consequences. Furthermore, various countries have paid attention to microfibers, considered the environment's most abundant form of pollutant. Microfibers are the primary marine pollutant in the world. Thousands of research studies have addressed the detrimental impact of these micropollutants on aquatic and terrestrial habitats, the food chain, and human health. Annually, around 2 thousand tons of microfibers are discharged from numerous sources into the water. Such microfibers are released from each piece of clothing throughout domestic laundry. Microfiber particles and washing machine wastewater are released into urban drainage systems next to lakes and rivers, eventually blending with ocean water. Ocean streams carry these tiny particles because of their low density. According to reports, environmental pollution caused by cleaning synthetic apparel at home is among the causes of primary microplastics in the aquatic environment. If fiber materials are not employed or handled correctly, they will, directly and indirectly, lead to severe microfibre environmental pollution. As microfibers are exposed to the natural environment, they fragment into smaller strands. Many technologies are now for removing microfibers, including physical, chemical, and biological methods. Because of membrane fouling and the need to replace old filter membranes, filtration technology has a range of removal efficiencies and a relatively high cost. Adsorption and magnetic separation are straightforward removal techniques, but adding additional sorbents can result in secondary contamination. Chemical residues provide a similar issue in the treatment of coagulation and oxidation. Similarly, biodegradation and bioreactors frequently have low degradation efficiencies. Future biodegradable plastic development, integrated environmentally friendly methods, recycling traditional plastic, and zero pollutant removal technologies were the final green plastic reduction techniques proposed. It is impossible to stress how crucial technical advancement is to enabling integrated water management. Water and wastewater treatment with nanotechnology has the potential to advance treatment effectiveness and increase water supply through the safe use of water sources. Here, we examine current advances in wastewater and water treatment using nanotechnology. Topics of discussion encompass potential nanomaterials, characteristics, and mechanisms that permit applications, benefits, and drawbacks compared to existing techniques, obstacles to commercialization, and research needs.
