Moringa seeds clean tap water by removing nearly all microplastics in lab study

Researchers in Brazil and the UK found moringa seed extracts act as a natural coagulant that removed about 98.5% of PVC microplastics from tap water in filtration tests, performing similarly to or better than alum and offering renewable, biodegradable advantages. Yet each seed treats only about 10 liters, raising scalability questions for large plants and leaving open questions about residues and effectiveness on other plastics or nanoplastics, necessitating further study especially for small communities.
