Indian Teens Win $12,500 Global Earth Prize for Tamarind-Based Microplastic Filter

Three 16-year-olds from India — Vivaan Chhawchharia, Ariana Agarwal and Avyana Mehta — were named Global Winners of The Earth Prize for Plas-Stick, the first Indian project to take the top award.
Plas-Stick uses powdered tamarind seed to bind microplastics into visible clumps that can be removed with a handheld magnet, offering a low-cost filtration method without electricity or complex infrastructure.
The team developed the solution after seeing rural communities store drinking water in shared containers without advanced filtration, a gap affecting populations among the 2.2 billion people lacking safely managed drinking water.
The Geneva-based prize, launched in 2019, includes a $12,500 grant; the students say they will use the recognition to expand decentralized production hubs and reach more rural communities across India.
Beyond the accolades, what is the biggest hurdle preventing this teen invention from purifying water for millions in rural India?
After Plas-Stick removes microplastics, what is the plan to safely dispose of the newly created toxic waste clumps?
Earth Prize 2026 Awarded to Indian Teens for Plas-Stick, a Tamarind-Based Microplastic Removal Innovation
Overview
A team of Indian teenagers was inspired to tackle microplastic pollution after witnessing a child drink unfiltered water from a shared plastic container in a rural community. Realizing the widespread risk of microplastics in drinking water, especially in underserved areas, they developed Plas-Stick—a biodegradable powder made from tamarind seed waste. By processing this agricultural by-product into an adsorbent, Plas-Stick effectively removes microplastics from water. This innovative solution offers a sustainable and accessible way to improve water quality for low-resource communities, demonstrating how local observations can lead to impactful environmental solutions.
