Three Indian teenagers have become the first-ever Global Winners from India at The Earth Prize 2026 for developing an innovative solution to tackle microplastic pollution in water.
Sixteen-year-olds Avyana Mehta, Ariana Agarwal, and Vivaan Chhawchharia created Plas-Stick, a biodegradable magnetic powder made from discarded tamarind seeds. When added to water, the powder binds with microplastic particles, allowing them to be easily removed using a magnet.
The idea was inspired by the students’ visit to a rural community, where they observed limited access to clean drinking water and affordable filtration systems. Their low-cost, electricity-free solution is designed to help underserved communities combat microplastic contamination.
After winning the Asia regional category, the team secured the global title through a public vote involving nearly 23,000 participants. The project has already reached over 8,000 students and teachers through workshops and demonstrations.
The young innovators now plan to expand Plas-Stick through decentralised production hubs and make the technology accessible to more rural communities across India.
Their achievement highlights India’s growing role in youth-led environmental innovation and sustainable solutions to global challenges.
