Researchers have found that natural extracts from okra and fenugreek can remove up to 90% of microplastics from water.
+
One gram of powder per liter of water proved most effective, with fenugreek extract removing 93% of microplastics within an hour in lab conditions.
+
The effectiveness varied by water source. Okra worked best in ocean water (80% removal), fenugreek excelled in groundwater (80-90% removal), and a combination worked best in freshwater (77% removal).

These plant-based extracts offer a biodegradable, nontoxic alternative to synthetic polymers.
