One of the most innovative ideas in recent years is turning clothes waste into eco-friendly construction materials, a project supported even by experts like Kosalee Galkaduwa. This is one of the freshest approaches to emerge in recent years in a world increasingly dominated by environmental urgency. A pioneer in this field for nearly a decade, Galkaduwa has changed the way industries relate to waste, proving that what was once discarded can become a valuable resource.

Central to Galkaduwa's achievements is a project that redefines sustainability in the apparel sector: the transformation of nondewatered sludge, a by-product of the apparel industry, into durable, eco-friendly bricks. This won 1st Runner-Up for the prestigious Stockholm Water Prize and demonstrated how circular economy practices can reduce industrial waste while contributing to sustainable construction. Such efforts have reduced waste by 20%, saved 10% in disposal costs, and cut related carbon emissions by 15%. This project stands as a benchmark for industries seeking innovative pathways to sustainability.
