The circular economy (CE) promotes sustainability by minimizing resource consumption and encouraging reuse, recycling, and recovery. Although Global North has advanced CE policies, Global South continues to face persistent challenges, including weak waste management systems and social inequality. This article creates and tests the "Circular Technical Network" (CTN) framework, designed to analyze policy content, institutional arrangements, and stakeholder roles in CE transitions. Using Colombia as a case study, the CTN framework identifies four critical success factors for an effective CE transition: overcoming fragmented governance and coordination challenges, clearly defining roles within recycling systems, integrating organic waste into Extended Producer Responsibility (EPR) regulations, and advancing the adoption of the 10Rs hierarchy. Based on these findings, strategic policy recommendations are organized across five interconnected dimensions: governance, legal/regulatory, financial and economic instruments, monitoring and information systems, and infrastructure. Together, the CTN framework and these recommendations provide policymakers and institutions in Global South countries with a structured tool for reshaping public policy and institutional design, facilitating a more sustainable CE transition.
