Scientists have found an unexpected ally in the fight against microplastic pollution: okra. It turns out that the mucilage in this plant can naturally attract plastic microparticles from water, offering a safe and environmentally friendly alternative to synthetic purification methods.
Scientists have discovered that common okra, a plant with a characteristic slimy texture, can help combat one of the most serious environmental threats of our time: microplastic pollution.
Research led by Dr Rajan Srinivasan of the University of Texas has shown that the polysaccharides contained in okra are capable of attracting microplastic particles in water. When combined with fenugreek or tamarind extracts, okra effectively purifies both sea and fresh water. The research data was published in the Global Journal of Medical Research.
Microplastics are tiny fragments of plastic less than 5 millimetres in size, formed when plastic products, synthetic clothing or car tyres break down. These particles are now found almost everywhere, from oceans to drinking water. According to the University of Newcastle in Australia, the average person consumes the equivalent of a credit card’s weight in microplastics every week.
Unlike synthetic flocculants, which are currently used in wastewater treatment plants, okra extracts are completely non-toxic, safe and compatible with existing water treatment technologies.
In addition, okra is known for its health benefits. This low-calorie product is rich in fibre, antioxidants and vitamin C, helps improve digestion, lower cholesterol and maintain kidney function.
Thus, humble okra can not only enrich the diet, but also become a natural means of cleaning the planet of microplastics – environmentally friendly, affordable and effective.
