The concept of the circular economy (CE) offers a transformative solution to pressing global challenges such as resource depletion, waste generation, and environmental degradation. By shifting from the traditional linear “take-make-dispose” model to a closed-loop system, the CE principles aim to enhance resource efficiency and sustainability. This paper proposes a Waste Reduction and Resource Optimization (WRRO)-oriented circular business model, offering a comprehensive theoretical framework to guide businesses in optimizing resource utilization and reducing waste. Through the exploration of academic literature and a practical case study, the paper illustrates how businesses can effectively transition to circular business models. It also addresses the challenges businesses face during implementation, providing actionable insights for both theory and practice. The paper’s key contribution lies in integrating circular economy principles with resource efficiency strategies, offering a novel approach that supports both environmental sustainability and economic performance.
