Although the use of plastics varies across different regions, Africa is ranked second after Asia as an indiscernible consumer of plastics that break down into microplastic. Moreover, little is known about the impact of these microplastics across the African continent. This review provides insight into what microplastics are and their impact on the environment across Africa. The mismanagement of plastic waste is at its peak in Africa, as the continent mismanages over 70% of daily generated waste on average through activities such as tourism, fishing, and waste transport from one end to the other through waterways. Regarding the impact of microplastics on the environment, we found that they facilitate severe environmental consequences, such as the development of metal toxicity within aquatic and terrestrial organisms, disruptions of the food chain in the ecosystem, and public health challenges to humans who consume seafood. Alternatively, bioplastics are promising biodegradable and environmentally friendly plastic materials that could be crucial in expanding Africa's plastic industry. Furthermore, the continent has some widely spread biobased renewable raw materials that can be harnessed for developing bioplastics. Therefore, biomass-based polymers are promising alternative plastic feedstocks for producing plastics because they can readily biodegrade and break down in industrial compost facilities.

Africa is a large continent ranked amongst the top consumer of plastic materials. However, the improper handling of plastic wastes has resulted in massive pollution of different aspects of the environment (water, soil, sediments, air, food, etc.) within and around the region. The fragmentation and biodegradation of the bulk plastic material into small-sized particles has given rise to microplastic and nanoplastics. Owing to their small sizes, ease of transport, and large surface area, they tend to wreak serious havoc in the environment. Nevertheless, the growing awareness of the pollution problems caused by micro/nanoplastic debris is instrumental towards circumventing its widespread across the ecosystem. This review provides a state-of-the-art information on the prevailing nanoplastic surge across the borders of Africa, the ineffective management policies of plastic wastes, potential environmental hazards, and possible remediation strategies. Additionally, prospective insights into new areas for advanced research were highlighted.
