The concept of 'circular economy' has gained significant traction in recent years as a sustainable alternative to the traditional linear model of 'take-make-dispose'. Unlike linear systems, which prioritize throughput and often externalize environmental costs, a circular economy emphasizes the continuous use of resources through strategies such as reuse, repair, remanufacturing, and recycling. Proponents argue that this approach not only reduces waste and resource depletion but also fosters innovation and economic resilience. However, critics point out that transitioning to a fully circular system faces substantial barriers, including technological limitations in material recovery, insufficient consumer participation, and the lack of supportive policy frameworks. Moreover, some scholars caution that 'circularity' can be co-opted by corporations as a greenwashing tool, allowing them to maintain unsustainable production levels while appearing environmentally responsible. Thus, while the circular economy offers a promising vision, its real-world implementation requires critical evaluation of both its ecological benefits and socio-economic implications.
