Can tamarind seeds really help clean polluted drinking water? A group of 16-year-old innovators from India has proven that simple ideas can create powerful environmental solutions. Their project, called “Plas-Stick,” has officially won the Asia title at The Earth Prize 2026, bringing global attention to Indian teenage innovation, eco-friendly water purification, and microplastic removal technology.
The students developed a low-cost and sustainable method to remove microplastics from water using waste tamarind seeds, commonly known as imli seeds. They transformed the seeds into a special magnetic powder that attracts tiny plastic particles floating in contaminated water. Once the particles stick together, they can easily be removed using a handheld magnet, leaving behind cleaner and safer drinking water. The innovation has impressed environmental experts because it combines affordability, simplicity, and eco-friendly science in a practical real-world solution.
The Earth Prize is an international environmental competition for teenagers aged 13 to 19, organized by The Earth Foundation in Switzerland. As Asia winners, the Indian team received $12,500 in funding to further test and expand their project. They are now competing alongside other regional finalists from around the world for the global title, which will be announced on May 29, 2026.
This achievement highlights how young minds in India are creating impactful environmental innovations that could help solve real global problems in the future.
