Three teenagers from India have earned global recognition after winning the prestigious Global Earth Prize for developing an innovative solution that helps remove microplastics from water using tamarind seed powder.
Earlier in May, GNN reported that three Indian students had won a major Asian science award for using a common ingredient found in Indian kitchens to create a microplastic filter. Now, they have achieved an even bigger milestone by winning the Global Earth Prize.
The winners are 16-year-olds Vivaan Chhawchharia, Ariana Agarwal, and Avyana Mehta. Their project was selected as the global winner after receiving votes from more than 23,000 experts from dozens of countries.
Students also shared their excitement about receiving the award.
“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.”
They also said:
“What started as an idea between students has now been recognised among thousands of projects from around the world, which feels both surreal and deeply motivating.”
What Is Plas-Stick?
The students created an invention called Plas-Stick, which uses powdered tamarind seed as the main ingredient in a natural microplastic-clumping agent.
When the powder is added to water and mixed for a short time, it causes tiny microplastic particles to gather together into visible clumps. These clumps can then be removed easily with the help of a magnet.
This simple process makes it possible to reduce microplastics in water without using expensive equipment or advanced filtration systems.
First Global Earth Prize Winner from India
Plas-Stick has made history by becoming the first project from India to win the Global Earth Prize.
The biodegradable powder was designed for use in shared water containers. It binds invisible plastic particles into larger clumps, making them easier to remove. Because of its low cost and simple design, it can be a practical solution for many communities.

How the Idea Started
The idea came from the students’ environmental science studies and a visit to a rural community.
During their visit, they noticed that drinking water is often stored in shared containers without access to advanced filtration systems. This inspired them to look for a simple and affordable way to improve water quality.
Their goal was to create a solution that could be used by people in resource-limited areas.
Why Microplastics Are a Growing Concern
Around the world, more than 2.2 billion people do not have access to safely managed drinking water infrastructure. As a result, many people depend on stored water that may contain microplastics.
Microplastics are extremely small plastic particles that have been found almost everywhere scientists have looked. These particles have been discovered on the summit of Mount Everest and even at the bottom of the Mariana Trench.
Researchers have also found microplastics in many human organs and tissues, including the brain and placenta. While scientists are still studying the full health effects of microplastic exposure, experts know that these particles can act as strong endocrine disruptors.
A Simple and Accessible Solution
Determined to create a solution that is both effective and accessible, Chhawchharia, Agarwal, and Mehta developed a system that does not require electricity or complex infrastructure.
Their invention uses tamarind, a crop that is already widely used in South Asian cuisine. Tamarind is commonly cultivated and also grows naturally in many regions, making it an affordable and easily available resource.
By combining local ingredients with environmental innovation, the three students have created a practical solution that could help communities reduce microplastic contamination in drinking water.
Conclusion
The success of Plas-Stick shows how young innovators can create meaningful solutions to global environmental challenges. By using tamarind seed powder to remove microplastics from water, three Indian teenagers have not only won the Global Earth Prize but also highlighted a simple and low-cost approach that could benefit millions of people around the world.
