Indian Teen Trio Wins The Earth Prize 2026 for Innovative Microplastic Filtration Solution

Team Plas-Stick represents exactly the kind of innovation The Earth Prize was created to elevate: solutions that are scientifically grounded, environmentally responsible and accessible to the communities that need them most. By transforming agricultural waste into a practical tool for removing microplastics from drinking water, these young innovators are addressing a growing global challenge with remarkable creativity and purpose.

Three Indian teenagers have become the first team from India to win the prestigious Earth Prize 2026, earning global recognition for developing an innovative, low-cost solution to remove microplastics from water. The achievement has been hailed as a powerful example of how young Indian innovators are tackling some of the world’s most pressing environmental challenges.

The winning team—16-year-olds Avyana Mehta, Ariana Agarwal, and Vivaan Chhawchharia—developed Plas-Stick, a biodegradable material made from tamarind seed waste that helps remove microplastic particles from water. The invention uses a magnetic tamarind-based powder that causes microplastics to clump together, allowing them to be easily extracted using a handheld magnet. The process is designed to be affordable, electricity-free, and suitable for communities with limited access to advanced water filtration systems.

Last week, around 23,000 people cast their votes to select the Global Winner from seven inspiring Regional Winners representing every continent: North America, Africa, Asia, Central and South America, Oceania and Southeast Asia, Europe, and the Middle East. Representing the Regional Winner for Asia, Plas-Stick had already received $12.5K to scale their solution.

“Being named the Global Winners of The Earth Prize is incredibly special for all of us, especially as the first team from India to receive this recognition,” the trio said in a statement.

The idea for Plas-Stick emerged after the team visited a rural community where drinking water was commonly stored in shared plastic containers, without advanced filtration systems. During this visit, seeing a child drink from one of these containers highlighted exposure to microplastics through everyday drinking water, particularly in underserved rural communities in India. Globally, over 2.2 billion people lack safely managed drinking water infrastructure, increasing reliance on stored water that may contain microplastics.

The Earth Prize, regarded as one of the world’s largest environmental competitions for young people aged 13 to 19, selected the Indian team as its Global Winners after the public vote. Their victory marks the first time an Indian team has secured the competition’s top global honour.

Peter McGarry, Founder of The Earth Foundation, praised the team’s achievement, saying:

“Team Plas-Stick represents exactly the kind of innovation The Earth Prize was created to elevate: solutions that are scientifically grounded, environmentally responsible and accessible to the communities that need them most. By transforming agricultural waste into a practical tool for removing microplastics from drinking water, these young innovators are addressing a growing global challenge with remarkable creativity and purpose.”

The success of Plas-Stick has drawn international attention not only for its scientific innovation but also for its potential social impact. Environmental experts have increasingly warned about the presence of microplastics in drinking water, making affordable filtration technologies a growing area of research worldwide.

Beyond the scientific breakthrough, the achievement highlights the growing presence of Indian students and young innovators on global platforms. Observers say the victory serves as a reminder that Indian talent continues to make its mark in science, technology, sustainability, and research, often outside the spotlight traditionally given to more visible fields.
