Ancient moringa seeds remove 98 percent of microplastics including PVC from tap water

A seed-based filter outperforms chemical alum in tests

A new study in ACS Omega finds moringa oleifera seeds can remove over 98% of harmful microplastics from water, including PVC particles. Researchers say the plant-based method matches or even outperforms conventional chemical treatment like alum. Because microplastics are linked to serious health risks, the work points to a non-toxic, sustainable option—but more trials are needed before cities adopt it.
