Moringa seed extract cleans drinking water of 98% microplastics, beating traditional coagulants
A Brazilian study finds a salt-based extract from moringa seeds removes over 98% of PVC microplastics from drinking water, matching or outperforming aluminum sulfate (alum) and potentially simplifying treatment by enabling inline filtration. The moringa option offers greener benefits and lower sludge but raises questions about dissolved organic carbon leaching and requires scaling tests before widespread use.
