This course introduces learners to the foundations of the circular economy, exploring how products, systems, and industries can shift from linear “take–make–dispose” models to sustainable, regenerative cycles. Participants will examine key concepts, principles, drivers, barriers, and sector‑specific applications—including plastics, fashion, finance, and the built environment. Through case studies and practical strategies, the course equips learners with the knowledge to design circular products, support transitions, and unlock economic, environmental, and social benefits.
