Faculty can use it as a core or supplementary text for courses in sustainability, innovation management, entrepreneurship, or circular economy studies. Each chapter explores key business frameworks, sectoral applications, and real-world case examples, making it ideal for lectures, group discussions, and experiential learning activities. Instructors are encouraged to use the content to prompt critical reflection on how different models function across contexts and to design assignments that challenge students to adapt or innovate circular solutions for specific industries or regions.
