Textile waste is a mounting global issue, contributing nearly 10% of carbon emissions (Igini, 2023), yet public understanding of its environmental and health impacts remains limited. This project uses game-based design to raise awareness and inspire behavioral change. Framed by the Stanford Design Thinking Process, grounded in empathy, creativity, and iteration, it reframes textile waste not just as a problem to solve, but as a catalyst for reimagining our material relationships and future systems. By integrating playful, interactive learning experiences rooted in human development theory, the project engages communities in meaningful dialogue and collective action. It encourages reflection, imagination, and responsibility, essential components of just, inclusive, and sustainable design futures. In alignment with the theme “Where Legacy Meets Future,” it honors design’s pedagogical roots while fostering a culture of transformation.
