The projections of global plastic production are based on a scenario that assumes current policies remain unchanged in the predictable future, highlighting the urgent need for improved waste management and policies to lessen the environmental impact.
As the situation intensifies, it becomes increasingly clear that innovative solutions are essential for tackling plastic waste in Africa. The existing recycling rates are very low, ranging from 15% to 25%, resulting in a substantial amount of plastic that contaminating soil and aquatic environments and hence increasing the health concerns among the living beings through the food chain. Annually, the African continent produces around 17 million tons (MT) of plastic waste, and among which a substantial quantity is deposited into aquatic environments, resulting in extensive harm to marine life and ecosystems. The success of programs aiming at decreasing plastic waste is sometimes hindered by poor governance, inadequate resources, and a lack of emphasis on addressing core issues such as insufficient recycling infrastructure and waste management systems.
Unfortunately, the majority of plastic wastes in Africa are either openly burned or dumped in landfills, resulting in environmental contamination and posing health problems. The widespread use of Single-Use Plastics (SUPs) is a significant issue, and although several African countries have introduced limits on SUPs, the implementation of these bans is inconsistent, and viable alternatives are often not readily available.
Evidence from research indicates that plastic wastes that are either in micro- or nanoparticle states are widespread in African water sources, with PES, PE, and PP being the predominant types discovered. In order to effectively address plastic pollution, it is crucial to implement sustainable solutions such as the circular economy (CE) and international collaboration.
In addition, there is a requirement for increased external financial and technical assistance, agreement among stakeholders, and efforts to raise awareness in order to improve waste management and enforce environmental rules. Promoting the adoption of eco-design concepts and the utilization of easily recyclable materials in the plastic and textile sectors can contribute to waste reduction. Moreover, it is crucial for future studies to give priority to the detection and categorization of plastic polymers in order to devise efficient measures to mitigate their impact on the environment. To effectively tackle the plastic waste crisis in Africa, it is necessary to adopt a comprehensive strategy that encompasses the enhancement of waste management infrastructure, the enforcement of strict laws, the promotion of recycling, and international collaboration.
Most African countries are challenged by the complex problem of effectively addressing the epidemic of plastic waste, which has been worsened by various interconnected factors. An important problem is the insufficient waste management infrastructure, which is basic in numerous areas, resulting in improper disposal techniques, including open burning and landfill dumping. These practices contribute to environmental contamination and pose health risks. Although SUP laws have the highest acceptance rate worldwide, their effectiveness is constrained by inadequate governance, limited resources, and insufficient enforcement mechanisms. Moreover, the recycling industries in most of the African countries are not well equipped as less than 10% of nations have efficient recycling facilities.
The lack of comprehensive studies on plastic pollution in soil and aquatic systems hinders the development of effective mitigation techniques. The full potential of recycling in terms of economic and environmental benefits is limited by deficiencies in infrastructure and a lack of financial assistance.
Novel approaches, like the conversion of PO plastic into sulfur (S)-free fuel oil using pyrolysis, show promise. However, its practical application is difficult because it requires the development of secure, effective, and cost-effective methods that can generate profits for operators in areas where the average daily wage is below USD3.
The global plastic convention in 2024 offered a chance for international cooperation and inventiveness, and had the potential to offer a legally enforceable structure to effectively tackle plastic pollution in all ecosystems.
