Researchers at Tarleton State University found that food-grade plant extracts from okra can remove microplastics from wastewater. The study discovered that polysaccharide extracts from plants like okra, fenugreek, cactus, aloe vera, and tamarind can make great flocculants for cleaning water. Polysaccharides from okra and fenugreek were found to be best for removing microplastics from ocean water, while a combination of okra and tamarind worked best for freshwater. Plant-based flocculants can be easily implemented in existing water treatment facilities.
