Abstract

The mismanagement of consumer-discarded plastic waste (CDPW) has raised global environmental concerns about climate change. The COVID-19 outbreak has generated ∼1.6 million tons of plastic waste per day in the form of personal protective equipment (masks, gloves, face shields, and sanitizer bottles). These plastic wastes are either combustible or openly dumped in aquatic and terrestrial environments. Open dumping upsurges emerging contaminants like micro-nano plastics (MNPs) that directly enter the ecosystem and cause severe impacts on flora and fauna. Therefore, it has become an utmost priority to determine sustainable technologies that can degrade or treat MNPs from the environment. The present review assesses the sources and impacts of MNPs, various challenges, and issues associated with their remediation techniques. Accordingly, a novel sustainable circular model is recommended to increase the degradation efficiency of MNPs using biochemical and biological methods. It is also concluded that the proposed model does not only overcome environmental issues but also provides a sustainable secondary resource to meet the sustainable development goals (SDGs).

一种新的循环方法来分析与微纳米塑料及其可持续修复技术相关的挑战。

消费者丢弃的塑料垃圾(CDPW)管理不善引发了全球对气候变化的环境担忧。新冠肺炎疫情每天产生约160万吨个人防护用品(口罩、手套、面罩、洗手液瓶)形式的塑料垃圾。这些塑料废物要么可燃，要么公开倾倒在水生和陆地环境中。露天倾倒会使微纳塑料等新出现的污染物激增，这些污染物直接进入生态系统，对动植物造成严重影响。因此，确定能够降解或处理环境中MNPs的可持续技术已成为重中之重。本综述评估了MNPs的来源和影响、各种挑战以及与其补救技术相关的问题。因此，建议采用一种新的可持续循环模型，利用生物化学和生物方法提高MNPs的降解效率。该模式不仅克服了环境问题，而且为实现可持续发展目标(SDGs)提供了可持续的二次资源。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
