A flexible textile electrode that turns industrial wastewater into a source of renewable energy. Made by layering carbon nanotubes and conductive polymer onto fabric, the material supports special biofilms that clean pollutants while generating electricity. Tested with real textile wastewater, the system removed over 80% of dyes and organic contaminants and delivered high power output. Affordable and scalable, it offers a circular, energy-positive solution for sustainable wastewater treatment in both industrial and underserved settings
