With the experience Soil Recipe by Heather Seo, people can transforms discarded organic waste into fertile soil, turning what is typically thrown away into a foundation for new life while reducing the demand for new raw materials. It works with natural materials—such as paper, wood, eggshells, and seeds—alongside clay, mycelium, and minerals, which are carefully combined into a living soil system. Her initiative embraces circular thinking by treating waste as part of an ongoing ecological cycle, in which materials return to the earth to support regeneration. At the same time, it fosters a sense of connection by inviting participants to create soil themselves, shifting their role from observer to co-creator within the process.

By moving beyond traditional waste management, Soil Recipe proposes a citizen-driven system in which everyday organic waste can be used to cultivate nature at home. It encourages a post-anthropocentric, soil-oriented perspective in which materials are no longer seen merely as human tools, but as active participants in ecological systems. Through sprouting soil sculptures in unique colours and forms as sources of inspiration, and a recipe book featuring more than ten soil formulations—with precise ratios, material applications, and explanations of, for example, pH values of different types of household waste—visitors are invited to take part in this walk-in workshop and create their own soil sculptures.
