Researchers at the National University of Singapore (NUS) have developed a novel water purification system using upcycled pomegranate peel. The innovation, announced on May 26, 2026, converts agricultural waste into a highly effective adsorbent material.
According to the study published in the journal 'Science of the Total Environment', the pomegranate peel-derived material can remove up to 99.9% of heavy metals, dyes, and pharmaceutical residues from water. The process involves carbonizing the peel at high temperatures and activating it with a chemical treatment.
Lead researcher Professor Wang Jing explained that the material's porous structure allows it to trap contaminants efficiently. 'This is a sustainable solution that addresses both water pollution and agricultural waste,' she said. The team estimates the production cost is 30% lower than conventional activated carbon.
The NUS team is now working with industry partners to scale up the technology for commercial use. Field tests in rural communities are planned for later this year.
