Summary
Researchers tested whether crushed PET plastic bottles could serve as support material in constructed wetlands for treating wastewater, while monitoring whether the plastic released additional microplastics into the treated water. The study explored both the utility of plastic waste in treatment systems and the risk of secondary microplastic pollution from the material.
