The crucial role of circular waste management systems in cutting waste leakage into aquatic environments
Summary
Researchers combined spatial modeling with global population and development projections to show that 70% of future plastic waste leaking into waterways will come from China, South Asia, Africa, and India, and that even aggressive circular economy strategies cannot fully eliminate this leakage before 2030. The findings underscore that preventing plastic from entering the waste stream — not just cleaning it up — is the most effective intervention.
Waste leakage has become a major global concern owing to the negative impacts on aquatic ecosystems and human health. We combine spatial analysis with the Shared Socioeconomic Pathways to project future waste leakage under current conditions and develop mitigation strategies up to 2040. Here we show that the majority (70%) of potential leakage of municipal solid waste into aquatic environments occurs in China, South Asia, Africa, and India. We show the need for the adoption of active mitigation strategies, in particular circular waste management systems, that could stop waste from entering the aquatic ecosystems in the first place. However, even in a scenario representing a sustainable world in which technical, social, and financial barriers are overcome and public awareness and participation to rapidly increase waste collection rates, reduce, reuse and recycling waste exist, it would be impossible to entirely eliminate waste leakage before 2030, failing to meet the waste-related Sustainable Development Goals.

Adoption of global circular waste management systems is crucial to cut leakage of waste into aquatic environments
Spatial modeling of global municipal solid waste leakage to aquatic environments found that even in a sustainable development scenario with full circular economy adoption, complete elimination of waste leakage before 2030 is impossible, indicating failure to meet waste-related Sustainable Development Goals.
Leaving a plastic legacy: current and future scenarios for mismanaged plastic waste in rivers
Researchers estimated that 0.8 million tonnes of mismanaged plastic waste enters rivers annually, affecting 84% of global rivers by surface area, and project a nearly three-fold increase by 2060 — though improved waste governance could reduce this pollution by up to 72%.
Delineating and preventing plastic waste leakage in the marine and terrestrial environment
Researchers outline the global challenge of plastic waste leaking into marine and land environments, tracing the problem to poor waste management, limited recycling technology, and low public awareness. The commentary calls for upstream design changes and downstream cleanup strategies to reduce plastic litter worldwide.
Global environmental plastics dispersal under OECD policy scenarios towards 2060
Researchers modeled how global plastic pollution would spread through the environment under different policy scenarios developed by the OECD, looking ahead to 2060. They found that even with ambitious policy action, significant amounts of plastic will continue leaking into aquatic environments unless waste management improves dramatically worldwide. The study suggests that coordinated global policies targeting both plastic production and waste management are essential to curb environmental plastic pollution.
Reduction scenarios of plastic waste emission guided by the probability distribution model to avoid additional ocean plastic pollution by 2050s
Researchers developed a probability distribution model to predict future marine macroplastic and microplastic abundances under various waste emission scenarios. The study suggests that to achieve zero additional ocean plastic pollution by 2050, global plastic waste emissions would need to be reduced by at least 32% relative to 2019 levels by around 2035, requiring stringent systemic changes in waste management.
