While there is ample research on the barriers and enablers for implementing circular economy (CE) in large companies and developed economies, scant research exists concerning the factors impacting CE implementation in small and medium enterprises (SMEs) in emerging economies. To address this gap, our research seeks to determine the internal and external barriers SMEs face when implementing CE initiatives in emerging economies and identify how they can leverage CE implementation through bottom-up approaches. We present a multiple-case study of five SMEs in Mexico. Our findings suggest that the lack of regional enabling conditions and unsuitability between the CE business strategy and the context can further exacerbate implementation barriers. In this sense, we found that in our study’s unsuccessful case, the company failed to align its business to the particularities of the markets where it operated. Contrary, successful initiatives adopted strategies that incorporated contextual attributes in their business models, such as available infrastructure, current regulations, or consumer characteristics. Our results provide lessons from both failing and successful CE initiatives implemented by SMEs in an emerging economy. This work intends to help practitioners, policymakers, and researchers to create the required enabling conditions to accelerate the transition toward a CE in these regions.

One of the main producers of wealth and prosperity of industrialized countries is the existence of sustainable systems, capable of converting technological innovation assets into substantial levels of industrial productivity, wealth and global competitiveness. However, very little has been capitalized from these cases for less developed regions. A framework is proposed (5Ls model), capable of empowering firms from industrial sectors of developing countries to: reach competitive Leverages; to Link and aLign these industrial clusters to their empowerment external drivers (academia, banking, complementary industries and government); to benchmark the cluster performance, against the best practices and Learn from the gaps; and, finally, to Lead and integrate the well performing clusters into world class value systems. To achieve these performances, a knowledge system architecture is proposed, which includes the 5Ls model supported by an effective structure of technological innovation systems (TIS), designed to administrate the collaboration network of diverse organizations, aligned to a common goal: the economic, social, political and cultural development of developing regions.

Sustainable development is a major concern for developing and developed economies as economic growth has to led to scarcer and more expensive resources. Although countries have established public policies focusing on resource and energy efficiency, there is an increasing need for a coordinated industrial strategy able to create sustainable wealth through a holistic management of natural resources, capable of "decoupling" economic growth from resource extraction and natural deterioration. Consequently, the objective of the present research is to develop a decoupling model able to create increasing economic returns, reducing the social gap and regenerating the natural capital for regions in developing countries. Departing from a literature review on peer reviewed articles on successful industrial cases of decoupling around the world, we contrasted the linear production model with the United Nations Environment Program (UNEP)'s current four decoupling indicators in order to propose a more robust model. The result was an eight-factor decoupling model that used a well-supported framework for sustainable wealth creation named "circular value ecosystem" (CVES). By using system dynamics, we deployed the proposed framework using system dynamics modeling in order to improve the understanding of our proposal. We found that this model, with the proper regional conditions in developing countries, can: (1) reduce, through substitution, the consumption of natural resources; (2) produce alternative economic increasing returns; (3) reduce the negative environmental impacts; and (4) create self-sustainable wealth for the economy, the environment, and the social development of most stakeholders of these regions. Decoupling economic growth represents a complex and challenging task whose successful implementation can only be achieved if managed at a regional level with a systemic approach.
