“…Polyethylene microplastics were broken up, and the results showed that the Antarctic krill's consumption of them changed their size (Euphausia superba) (Dawson et al, 2018). The previous research' findings regarding the fragmentation and disintegration of microplastics were supported by both microscopic and FTIR images (Bharath et al, 2022).…”

“…Although microplastics are not intended to be removed by standard sewage treatments, they do so to some extent. The removal efficiency would be 71.67% during the main procedures, but by the end of the advanced phases, it could remove 99.9% of the microplastics (Bharath et al., 2022; Talvitie et al., 2017). Exhibit 3 shows the various physical methods of microplastic removal.…”

“…In general, membrane technologies are more effective at removing microplastics from fresh water. However, the effectiveness of these technologies is highly dependent on a number of variables, including the amount of microplastics present in a matrix, the size and durability of the membrane, changes in influent and effluent water flow, and many more (Bharath et al., 2022).…”

Microplastics are the basic particles (1 µm–1 mm), derived from degradation of polymers with maximum molecular weight via various sources. They occur in a variety of shapes and sizes, in the form of domains, particles, and fibers. Release of Microplastics in the ecosystem, due to deterioration of macroplastics are now being considered as major toxic pollutants. Accumulation of microplastics in the diverse ecosystems is known to cause severe health and ecological effects. Since it is mandatory to take steps towards the removal of microplastics through effective and safe technology, with this objective, the present study is undertaken to reveal various green technology principles for the management of microplastics contamination associated with diverse environmental sources. This strategy involves physical methods, chemical methods, biological methods that under the conventional measures and nanotechnology principles as modern remediation. Physical methods involve filtration, membrane‐technology and adsorption. Chemical remediation involves hydrolysis, alcoholysis, acidolysis, glycolysis, aminolysis, photocatalytic degradation and electrochemical oxidation resulting in decomposition of microplastics into simpler, non‐toxic end products. Biological methods involve biosorption, microbial degradation, microbial ingestion and phytoremediation, where plants or plant biomass can be used for removal of microplastics via phytoaccumulation, phytostabilization, phytovolatilization and phytofiltration. Nano technology remediation utilizes nanoscale materials as adsorbents. Due to its unique nanosize, high surface area and energy, nanomaterials are considered effective adsorbents of microplastics. Microplastics can also be detected and identified using machine learning approaches. The present study implies that, the green technology principles can be effectively utilized for the removal of microplastics associated with diverse ecosystem.

The dawn of mass plastic production in the early 20th century has accelerated the penetration of microplastics into the environment, making them known to be an insidious threat to diverse ecosystems. The current scenario for microplastics is dire, as they pervade living organisms and disrupt vital functions while also affecting the environment by altering soil quality. They pose an inherent risk to human health, making their elimination a multifaceted challenge. Due to factors such as small size, low biodegradability, and ubiquity, microplastics are particularly challenging to detect, and methods for their elimination from terrestrial and marine environments are an ever‐evolving field of research. The detection of such microplastics has necessitated the use of various biotechnological techniques to monitor microplastic pollution. The control of microplastic pollution in natural ecosystems can be met by replacing mass‐produced single‐use plastics with viable bio‐based alternatives. The main objectives of this review are to discuss how microplastic pollution is currently monitored, assessed, and controlled using satellite‐generated imagery complemented with a range of biotechnological and bioremedial techniques. This review also traces the development of a range of bio‐based plastic alternatives that are observed to potentially replace single‐use plastics. Further discussion on the various challenges and prospects for the mitigation of microplastics will also be conducted, stressing the importance of future research.
