- Three Indian teenagers—Vivaan Chhawchharia, Ariana Agarwal, and Avyana Mehta (aged 16 years)—won the Earth Prize (Global Winners) for developing Plas-Stick, a biodegradable water filtration innovation.
- Plas-Stick is a powder made from tamarind seed waste used to remove microplastics from water.
- It works by attracting microplastic particles and forming clumps that can be removed using a handheld magnet.
- The method is electricity-free, low-cost, and designed for rural and low-resource areas.
- The project was developed with support from the Indian Institute of Technology (IIT) Guwahati and has received a US$12,500 grant.
