The SARS-CoV-2 pandemic has demonstrated both positive and negative effects on the environment. Major concerns over personal hygiene, mandated and ease in lockdown actions and slackening of some policy measures have led to a massive surge in the use of disposable personal protective equipment (PPE) and other single-use plastic items. This generated an enormous amount of plastic waste from both healthcare and household units, and will continue to do so for the foreseeable future. Apart from the healthcare workers, the general public have become accustomed to using PPE. These habits are threatening the land and marine environment with immense loads of plastic waste, due to improper disposal practices across the world, especially in developing nations. Contaminated PPE has already made its way to the oceans which will inevitably produce plastic particles alongside other pathogen-driven diseases. This study provided an estimation-based approach in quantifying the amount of contaminated plastic waste that can be expected daily from the massive usage of PPE (e.g. facemasks) because of the countrywide mandated regulations on PPE usage. The situation of Bangladesh has been analysed and projections revealed that a total of 3.4 billion pieces of single-use facemask, hand sanitizer bottles, hand gloves and disposable polyethylene bags will be produced monthly, which will give rise to 472.30 t of disposable plastic waste per day. The equations provided for the quantification of waste from used single-use plastic and PPE can be used for other countries for rough estimations. Then, the discussed recommendations will help concerned authorities and policy makers to design effective response plans. Sustainable plastic waste management for the current and post-pandemic period can be imagined and acted upon.
SARS-CoV-2 大流行对环境产生了正反两方面的影响。人们对个人卫生高度关注,强制封锁和放松部分政策措施,导致一次性个人防护设备(PPE)和其他一次性塑料用品的使用量大幅增加。这导致来自医疗和家庭单位的大量塑料废物,并且在可预见的未来还将继续如此。除了医护人员外,公众也已经习惯使用 PPE。由于全世界(尤其是发展中国家)的不当处理做法,这些习惯正威胁着陆地和海洋环境,带来大量塑料废物。受污染的 PPE 已经进入海洋,这将不可避免地与其他病原体驱动的疾病一起产生塑料颗粒。本研究提供了一种基于估算的方法来量化由于全国范围内对 PPE 使用的强制性规定,预计每天将有多少受污染的塑料废物(例如口罩)。对孟加拉国的情况进行了分析和预测,结果表明,每月将生产 34 亿个一次性口罩、洗手液瓶、手套和一次性聚乙烯袋,每天将产生 472.30 吨一次性塑料废物。用于量化使用过的一次性塑料和 PPE 废物的方程可用于其他国家进行粗略估算。然后,所讨论的建议将帮助有关当局和决策者制定有效的应对计划。可以想象并采取行动,实现当前和大流行后时期的可持续塑料废物管理。
