How plastic waste management affects the accumulation of microplastics in waters: a review for transport mechanisms and routes of microplastics in aquatic environments and a timeline for their fate and occurrence (past, present, and future)
This review traces how plastic waste management practices influence the accumulation and transport of microplastics in freshwater and marine environments over time. Researchers found that improper waste handling, surface runoff, and wastewater discharge are the primary pathways through which microplastics enter aquatic systems. The study provides a timeline perspective showing that without improved waste management, microplastic concentrations in water bodies are projected to continue rising significantly.
New Management Strategy Framework for Effectively Managing Microplastic in Circular System from Plastic Product Manufacturing to Waste Treatment Facility
Researchers proposed a new management strategy framework for controlling microplastic release throughout the lifecycle of plastic products, from manufacturing through end-of-life in circular economy systems, incorporating soil, atmospheric, groundwater, and river-based pollution pathways. The framework provides actionable guidance for producers, regulators, and waste managers to systematically reduce microplastic entry into land and marine environments.

A threshold model of plastic waste fragmentation: New insights into the distribution of microplastics in the ocean and its evolution over time
Researchers developed a fragmentation model for plastic particles in the ocean that postulates a critical size threshold below which further fragmentation becomes extremely unlikely, producing a predicted abundance peak around 1 mm in agreement with field data. The model incorporates realistic environmental input rates and degradation kinetics to project the evolution of microplastic particle size distributions over time.
Marine plastic pollution: A systematic review of management strategies through a macroscope approach
