Research on Development of Circular Design of Sustainable Products for Resource Reuse under Circular Economy

Nowadays, many design models and strategies are mentioned in the development of a circular economy, and enterprises also are adopting their applicable implementation methods. There are different levels of consideration of the circular economy from the selection of raw materials to the production process of products and the final recycling. Therefore, it is required to further explore and analyze how and when companies better create and how they value sustainable products. Therefore, this research was carried out to understand the company's design thinking model for product sustainability and find out the relevant vital elements. After completing the expert interview, grounded theory was used to analyze the collected data by grouping them into the categories of "open coding", "axis coding" and "selective coding". The results allowed the understanding of all aspects of sustainable product design development such as the current environment, design methods, operations management, loop feedback, and future-looking projects. At the same time, a feasible business model with a sustainable product cycle design was discussed. Based on the result and discussion, suggestions and opinions were made for the practical circular design of enterprises, the direction of the design and necessary considerations, and the implementation of the design as references for sustainable product development of the industry.
