The concept of 'circular economy' has gained significant traction in recent years as a response to the linear 'take-make-dispose' model that dominates modern production. Unlike traditional recycling, which often downcycles materials into lower-quality products, a circular economy aims to maintain the highest utility and value of products, components, and materials at all times. This is achieved through strategies such as product longevity, repair, remanufacturing, and sharing platforms. Proponents argue that this systemic shift not only reduces environmental impact but also fosters innovation and economic resilience. However, critics point to substantial barriers, including consumer behavior, inadequate infrastructure, and the complexity of global supply chains. They contend that without strong policy interventions and corporate accountability, the transition remains largely aspirational. Nevertheless, pilot projects in electronics and fashion demonstrate that circular principles can be practically applied, suggesting that a more sustainable production paradigm is feasible, albeit requiring coordinated efforts across sectors.
