ClearWastewater Treatment by Constructed Wetland Eco-Technology: Influence of Mineral and Plastic Materials as Filter Media and Tropical Ornamental Plants
Constructed wetlands using ornamental plants effectively removed chemical pollutants from wastewater, and the presence of plastic residues in the growing medium affected treatment performance. This finding is relevant to understanding how microplastics in constructed wetlands may interfere with natural water purification processes.
Water hyacinth-inspired self-floating photocatalytic system for efficient and sustainable water purification
Researchers developed a floating water purification device inspired by the water hyacinth plant, combining a buoyant porous structure with a light-activated photocatalyst to break down pollutants. The device effectively degraded various contaminants including dyes, antibiotics, and microplastics using only sunlight, while remaining stable in both still and flowing water. The study demonstrates a practical, sustainable approach to water cleanup that works without chemicals or external energy sources.
Phytoremediation An Effective Technique for Domestic Wastewater Treatment

Phytoremediation of Polluted Waterbodies with Aquatic plants: Recent Progress on Heavy Metal and Organic Pollutants
This review surveys phytoremediation strategies using aquatic plants to remove heavy metals and organic pollutants from contaminated water. Aquatic plants are also impacted by microplastic pollution, and understanding their tolerance and remediation capacity is relevant to restoring water quality in contaminated environments.
A low-impact nature-based solution for reducing aquatic microplastics from freshwater ecosystems
Researchers developed a nature-based solution using the submerged plant Myriophyllum aquaticum to capture and retain microplastics from freshwater ecosystems. Through optimization experiments, they achieved high retention efficiency with minimal environmental disruption. The study demonstrates that aquatic plants can serve as a low-impact, practical tool for reducing microplastic pollution in rivers and lakes.
Integrated application of macrophytes and zooplankton for wastewater treatment
Researchers examined the integrated application of macrophytes and zooplankton in constructed wetland systems for wastewater treatment, finding that filter-feeding zooplankton combined with aquatic plants can function as effective bio-purifiers for improving sewage treatment at discharge sites.
Phytoremediation of microplastics by water hyacinth
Researchers found that water hyacinth, a fast-growing floating plant, can remove 55-69% of microplastics from contaminated water within 48 hours through root adsorption. The plant's massive root surface area traps plastic particles, while a special structure in the stem prevents the plastics from reaching the leaves. This study offers a promising natural, low-cost approach to cleaning microplastics from waterways.
Water hyacinths retain river plastics
Researchers investigated how water hyacinths, an invasive aquatic plant common in tropical rivers, interact with floating plastic debris. They found that dense water hyacinth patches efficiently trap surface plastics, potentially influencing whether plastic waste reaches the ocean. The study suggests that while water hyacinths are typically considered a nuisance species, they may play an unintended role in retaining river plastics.
