Microplastics’ dangers and the absence of effective
regulation technologies have risen to prominence as a worldwide issue in
recent years. South Asian countries, such as Bangladesh, are among the
most threatened nations to face the drastic consequence of releasing
microplastics into the aquatic environment. The research on managing and
degrading microplastics is ongoing, however, sustainable techniques
have not yet been found. To create a green and efficient microplastic
management plan, we have compiled all the information on the existing
removal and degradation techniques for microplastics and provided an
overview of all the noteworthy methods that can be implemented in
Bangladesh. In the portrayed biotic and abiotic techniques, coagulation
and photocatalysis were found to be most efficient in removing
microplastics (as high as 99%) in different studies. The concept of
microplastic is new to the researchers of Bangladesh, therefore, the
characteristics, occurrence, fate, and threats are briefly discussed in
this paper. Sampling, extraction, and identification methods of
microplastic in freshwater and sediment samples are also thoroughly
specified. The sources of microplastic pollution in Bangladesh and
possible strategies that can be implemented to minimize additional
microplastic discharge into aquatic environments are discussed. Although
Bangladesh was the very first country to ban polythene, the failure of
the implementation of rules and regulations and a lack of management
strategy made Bangladesh the 10th worst country in managing plastic
waste. This work is a wake-up call for other researchers to conduct an
in-depth investigation to improve microplastic degrading technologies
and develop a sustainable strategy to end microplastic pollution in
Bangladesh.
