Three 16-year-olds from India have won the Global Earth Prize in Geneva for inventing a tamarind powder solution that removes microplastics from water.
Vivaan Chhawchharia, Ariana Agarwal, and Avyana Mehta developed the innovation using tamarind, a common ingredient in Indian cuisine, as the active basis for a microplastic filtration system. The trio had already claimed a major continental science prize in mid-May, when Good News Network first reported their breakthrough. The Geneva announcement confirms their work has now reached the highest level of global recognition.
From the Kitchen to the Lab
The core insight behind the invention is elegantly simple: tamarind, long used in cooking across South Asia, contains properties capable of binding to and extracting microplastics from water. By converting this into a powder format, the three students created a solution that is both accessible and easy to deploy.
Microplastics have become one of the most urgent environmental crises of the modern era, detected in drinking water, oceans, soil, and even human blood. Most existing removal technologies are expensive, complex, or difficult to scale. A tamarind-based powder changes that equation significantly.
Why This Matters
Vivaan Chhawchharia, Ariana Agarwal, and Avyana Mehta have demonstrated that world-changing science does not require enormous laboratories or decades of research. Three teenagers, drawing on a culinary tradition familiar to billions, have produced a solution to one of the planet’s most stubborn pollution problems — and earned global recognition twice over before finishing high school.
