Since 2003, Kamikatsu in Japan has established a sustainable zero-waste practice that has achieved a recycling rate exceeding 80%. By exploring how the community has shaped itself around the zero-waste concept, this paper aims to enhance our understanding of zero waste in practice from a universal design perspective. Interviews and photo documentation were used to gather data. The zero-waste concept was not driven by technical solutions. Instead, the results highlight what initiatives contributed to the design of the zero-waste concept. Key themes presented include fostering a lifestyle shift, changing norms, creating co-located experiences, establishing an incentive system, and developing self-awareness routines. The paper also addresses the challenges and opportunities from a universal design perspective when applying zero waste, emphasizing the importance of designing for diverse needs while promoting long-term environmental sustainability. This research contributes to the understanding of zero waste practices, combining the ecological dimension with the social dimension of sustainable development.
