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'. In a circular system, resources are kept in use for as long as possible, extracting maximum value during their lifecycle, and then products and materials are recovered and regenerated at the end of each service life. This approach contrasts sharply with the linear economy, which relies on large quantities of cheap, easily accessible materials and energy. However, transitioning to a circular economy is not merely a technical challenge; it requires systemic changes in business models, consumer behavior, and policy frameworks. For instance, product design must prioritize durability and repairability, while consumers must embrace sharing or leasing over ownership. Moreover, without robust regulatory incentives and international cooperation, the circular economy risks remaining a niche ideal rather than a global norm.
