A tree known for nutrition and medicine may now have another unexpected role. 🌿
Scientists studying Moringa oleifera found its seeds can remove over 98% of microplastics from tap water. Instead of relying on industrial chemicals, the seeds act as a natural coagulant, pulling tiny plastic particles together so they can be filtered out more easily.
The research focused on PVC microplastics, which are common in drinking water and among the more harmful types. In testing, the plant-based method performed about as well as aluminum sulfate, a widely used chemical in water treatment systems.
That matters because microplastics have now been detected in water worldwide, and even inside human organs. While scientists are still studying long-term effects, exposure is rising.
There are limits. One seed treats about 10 liters, so scaling this for large cities remains a challenge. Researchers also need to test whether it works on smaller particles like nanoplastics.
Still, the idea is simple and powerful. A fast-growing tree could become part of the solution to one of the planet’s most widespread pollution problems.
