From euronews:
A millenia-old purification technique could be the cure for Europe’s microplastic-riddled drinking water.
In a recent study, seeds from the ‘miracle’ moringa tree were found to match or outperform their chemical counterpart in filtering out aged PVC microplastics – one of the most harmful plastic types for human health. The findings could pave the way for a greener alternative for treatment plants. The use of moringa for purification is as old as it is innovative: it is thought to have been used by Ancient Egyptians to remove bacteria and reduce turbidity of water.
