Plant Based Application for Microplastic Removal in Constructed Wetlands: A Mini Review
Summary
This mini-review examines how wetland plants in constructed wetlands capture and degrade microplastics through physical entrapment, root-zone interactions, and microbial activity, assessing operational factors that determine removal efficiency.
Microplastic (MP) pollution is a global concern due to its harmful impact on ecosystems and human health. Constructed wetlands (CWs) have emerged as the most technology for wastewater treatment. Pollutants removal in CWs mainly comes from plants, microorganisms, and substrate. an eco-friendly wastewater treatment technology, have shown promise. This mini-review explores the potential of plant-based approaches in mitigating MP contamination. It highlights the role of wetland plants in capturing and degrading MP through physical, chemical, and biological mechanisms. The operational conditions in the removal efficiency were examined which involves hydraulic retention time and wetland design. By incorporating sustainable plantbased methods, constructed wetlands serve as a dual-purpose system for wastewater treatment and MP mitigation. This study emphasizes the need for further research to optimize plant selection and enhance the scalability of this ecoinnovative solution.
