Design of the waste Separation educational tools for Infants to Eco-Friendly Life education

As the importance of the Sustainable Development Goals (SDGs) is expanding, the need for early childhood environmental education that approaches them from a life-cycle perspective is also growing. Therefore, this study proposes a three-step design of learning materials for the formation of separation habits in toddlers and aims to view environmental education from a lifelong learning perspective. In addition, service design tools such as journey maps, affinity diagrams, and expert interviews were used to enhance the understanding of the target audience, and the initial concept of Product Service System (PSS) was used to understand the process of toddlers' awareness of building a sustainable society until adulthood. The three teaching aids created were designed to include playful elements to engage toddlers, allowing them to learn about the concept and practice of separating waste in a natural way. In this sense, this study aims to contribute to the development of environmental awareness and the formation of eco-friendly habits in young children. Furthermore, it focuses on enabling toddlers to continue to maintain and practice these habits even after they reach adulthood. In doing so, we hope to provide useful implications for the future development of early childhood environmental education programs.
