Jackfruit Peels to the Rescue: NIT Rourkela's Game-Changing Tech Cleans India's Water

Researchers at the National Institute of Technology (NIT) Rourkela have clinched a patent for an innovative, low-cost material made from discarded jackfruit peel that promises to revolutionize access to safe drinking water in India. This new adsorbent, enhanced with zirconium, effectively removes over 90% of excess fluoride from contaminated groundwater in a swift 10 to 20 minutes during laboratory tests. The breakthrough comes as India grapples with a severe groundwater contamination crisis, where millions in hundreds of districts face health risks from high fluoride levels, leading to debilitating conditions like dental and skeletal fluorosis. Current defluoridation methods often fall short; reverse osmosis wastes significant water and beneficial minerals, while ion exchange and activated alumina processes rely on harsh chemicals. NIT Rourkela eco-friendly solution not only provides a sustainable alternative but also champions a 'waste-to-resource' approach, transforming agricultural byproduct into a vital public health tool. Now operating at Technology Readiness Level 4, indicating successful lab validation, the research team — led by Professor Susmita Mishra and Pratima Minz — is gearing up for the next crucial phase: developing a physical prototype and assessing its long-term performance and operational costs for real-world deployment. The ambition is to scale this invention for decentralized water treatment, particularly in rural and semi-urban areas lacking robust infrastructure. This development marks a significant stride in India's ongoing efforts to ensure potable water for all and positions agricultural waste as a key player in environmental solutions.
