In a remarkable study initiated in 2022, a team of researchers at Tarleton State University began exploring how the natural sliminess of okra and fenugreek could be harnessed to combat microplastics. They discovered that these plant extracts not only attract but also effectively remove microplastics from various water sources, including oceans and freshwater bodies.

Backed by funding from the U.S. Department of Energy, the research led by Rajani Srinivasan has shown incredible promise. The slimy properties of okra and fenugreek act as natural polymers that can bind to microplastic particles, causing them to clump together and sink. This offers a practical solution to a problem that plagues our waterways.

To extract these sticky substances, the researchers soaked sliced okra pods and blended fenugreek seeds in water overnight. After separating the extracts and drying them into a powder, they analyzed the results. What they found was astonishing:

• One gram of either powder could effectively trap microplastics in a liter of water.
• Dried okra extracts removed 67% of plastics, while fenugreek achieved an impressive 93%.
• A 1:1 mix of the two extracts managed a removal efficiency of 70% in just half an hour.
• These natural agents outperformed synthetic polymers currently used in water treatment.

Equipped with real-world water samples collected from Texas waterways, the team tested their extracts under various conditions. Results varied based on water type: okra excelled in ocean water, fenugreek thrived in groundwater, and the combined mixture showed its strength in freshwater. Researchers also proposed that each water source contained different kinds of microplastics, affecting removal efficiency.

Unlike conventional treatments that might introduce toxicity, okra and fenugreek offer biodegradable alternatives. Srinivasan emphasizes the potential health benefits of using these natural extracts, highlighting their non-toxic nature: “Utilizing these plant-based extracts for water treatment not only clears microplastics but does so without adding harmful substances to our water supply,” she stated.

Before embarking on this journey, she had successfully tested food-grade extracts for removing textile pollutants. It was only natural, then, to explore their effectiveness against microplastics!
