Three Indian teens have developed a groundbreaking microplastic removal powder from tamarind seeds, winning Asia's Earth Prize 2026 and a $100,000 grant to expand their eco-friendly invention.
- Tamarind seed powder binds microplastics for easy magnetic removal.
- Prize includes $100,000 to scale their invention across India.
- Over 2 billion people lack access to safely managed drinking water.
What happened
In 2026, three 16-year-olds from India—Vivaan Chhawchharia, Ariana Agarwal, and Avyana Mehta—won Asia’s Earth Prize for creating an innovative way to remove microplastics from water. Their invention, called 'Plas-Stick,' uses powdered tamarind seeds as a natural agent to bind microplastics into visible clumps that can be removed simply with a handheld magnet. This method is affordable, biodegradable, and requires no electricity or complex filtration systems.
The idea originated from their observations of rural water storage practices, where communities often rely on shared water containers without effective filtration. With over 2.2 billion people worldwide lacking safely managed drinking water, the teens focused on an accessible solution to tackle the invisible but harmful pollution of microplastics in water supplies.
Why it feels good
'Plas-Stick' offers a promising solution to a widespread environmental health challenge by turning a ubiquitous kitchen ingredient into an effective filter for microplastics. Microplastics have been found globally, from the highest mountains to the deepest ocean trenches, and in human organs, posing risks to both ecosystems and people. By creating a low-cost, user-friendly method, these young innovators are providing hope for safer water in underserved communities.
Their invention also exemplifies how young minds and grassroots innovation can address complex environmental issues. Winning the Earth Prize not only validates their work but also empowers them to expand impact through decentralized production, helping scale the benefits to communities across India and potentially beyond.
What to enjoy or watch next
Follow the progress of 'Plas-Stick' as the team uses their $100,000 Earth Prize grant to bring the product to more rural areas without filtration access. Their effort highlights a growing movement of student-led environmental innovations, inspiring similar projects worldwide aimed at climate adaptation and pollution reduction.
Meanwhile, keep an eye on young scientists and inventors globally participating in initiatives like the Earth Prize, which was launched in 2019 to transform climate anxiety into positive, impactful action. Innovations like these signal a hopeful future where creativity and science combine to protect our planet.
