The anthropogenic deployment of plastic waste, especially petroleum-based plastics with toxic hydrocarbons, presents a significant environmental and health threat in sub-Saharan Africa (SSA). Herein, the high demand and rapid plastic production, coupled with improper disposal and inadequate waste management, have led to widespread contamination of air, water, and soil. Conventionally, plastic waste management, such as incineration and recycling, provides limited long-term solutions to this growing crisis. This necessitates urgent, sustainable, and eco-friendly remediation techniques to mitigate its far-reaching environmental implications. This comprehensive review focused on sustainable and eco-friendly techniques by exploring strengths, weaknesses, opportunities, and threats (SWOT) analysis of plastic waste management. Bioremediation techniques were found as potential solutions for addressing plastic waste in SSA. This paper examines advancements in physiochemical methods, the challenges in managing various plastic types, and the role of enzymatic and microbial consortia in enhancing biodegradation. It also explores the potential of genomic technologies and engineered microbial systems to convert plastic waste into valuable products, including bioenergy via bio-upcycling. These bioremediation strategies align with the United Nations Sustainable Development Goals (UN SDGs), offering a promising path to reduce the environmental and health impacts of plastic pollution in the region. This paper also considers future directions of integrating AI-powered recycling systems to facilitate the development of a circular economy in SSA. Additionally, this paper provides progress and future perspectives on bioremediation as a sustainable solution for plastic waste management in SSA.
塑料垃圾的人为排放,尤其是含有有毒碳氢化合物的石油基塑料,给撒哈拉以南非洲地区(SSA)带来了重大的环境和健康威胁。在此,高需求和快速的塑料生产,再加上处置不当和废物管理不足,导致空气、水和土壤受到广泛污染。传统上,塑料垃圾管理,如焚烧和回收,只能为这一日益严重的危机提供有限的长期解决方案。这就需要采取紧急、可持续且环保的修复技术,以减轻其深远的环境影响。本综述通过对塑料垃圾管理的优势、劣势、机会和威胁(SWOT)分析,聚焦于可持续和环保技术。生物修复技术被认为是解决撒哈拉以南非洲地区塑料垃圾问题的潜在方案。本文研究了物理化学方法的进展、管理各种塑料类型所面临的挑战,以及酶和微生物群落增强生物降解的作用。它还探讨了基因组技术和工程微生物系统将塑料垃圾转化为有价值产品的潜力,包括通过生物升级回收生物能源。这些生物修复策略符合联合国可持续发展目标(UN SDGs),为减少该地区塑料污染对环境和健康的影响提供了一条有前景的途径。本文还考虑了整合人工智能驱动的回收系统以促进撒哈拉以南非洲地区循环经济发展的未来方向。此外,本文提供了生物修复作为撒哈拉以南非洲地区塑料垃圾管理可持续解决方案的进展和未来展望。
