Recently, the issues of land-based plastics and their associated challenges in the marine world have been widely publicised in the media and scientific literature. Thus far, despite these communications, there have been few reports that have focused on the issues that acute plastic waste generation and its poor management pose to human health and the global environment. Also, articles on ways to mitigate these issues particularly in sub-Saharan Africa have not been documented. Indeed, there is significant scope for improvements in plastic waste management in developing countries, which offer a wide range of economic and environmental benefits. Plastic waste generation in sub-Saharan Africa is dependent on many factors like urbanization, etc. Currently, the population of sub-Saharan Africa is around 1 billion as of the year 2019, the amount of generated waste is 180 million tonnes at the rate of 0.5% per capita per day, the amount that is openly dumped is 70% and the plastic waste generated annually is 17 million tonnes. Therefore, this study aims to provide an overview of the plastic lifecycle and problems associated with plastic waste management in sub-Saharan Africa, including current practices, public participation and opinion, and government regulations. In addition, this highlight aims to outline the impact of plastic waste proliferation on man and the environment; and the economic and environmental benefits of proper plastic waste management. Critical discussion of current processes and the suitability of potential solutions provide the basis for proposition on mitigation measures to avert the negative impact of plastic waste.
最近，陆地塑料及其在海洋世界中相关挑战的问题在媒体和科学文献中得到了广泛宣传。尽管有这些信息交流，但很少有报道关注急性塑料废物产生及其管理不善对人类健康和全球环境造成的问题。此外，也没有记录关于减轻这些问题的方法的文章，特别是在撒哈拉以南非洲。事实上，发展中国家在塑料废物管理方面有很大的改进空间，这将带来广泛的经济和环境效益。撒哈拉以南非洲的塑料废物产生取决于城市化等许多因素。目前，撒哈拉以南非洲的人口约为 10 亿，截至 2019 年，人均每天产生的废物量为 0.5%，即 1.8 亿吨，其中 70%是露天倾倒的，每年产生的塑料废物量为 1700 万吨。因此，本研究旨在概述撒哈拉以南非洲塑料生命周期和与塑料废物管理相关的问题，包括当前的做法、公众参与和意见以及政府法规。此外，本重点介绍旨在概述塑料废物扩散对人类和环境的影响；以及妥善管理塑料废物的经济和环境效益。对当前流程的批判性讨论和潜在解决方案的适用性为提出缓解措施提供了基础，以避免塑料废物的负面影响。
