Navigating value networks to co-create sustainable business models: An actionable staging approach

Sustainable transitions typically require collaboration between multiple actors in the value chain or value network. Recent research has emphasized mapping of stakeholders and values as a starting point for identifying opportunities to realign these relationships, followed by business model experimentation to enable change. However, a simple mapping exercise does not consider the interplay between actors' concerns, business models, and interpretations of sustainability. Pedersen et al. (2022) advocated that aligning concerns is essential to collaborative design and innovation, and requires continuous negotiation between multiple actors. Here, we present a microlevel in-depth case study to examine how alignment across central value chain actors may be facilitated through the staging of numerous negotiations during the innovation process. Drawing on the staging negotiation spaces co-design framework, we provide insight into the content of multiple negotiations concerned with different aspects of sustainability during the development of a more sustainable laundry service system on the Danish island of Bornholm. Our findings illustrate how both value chain actors and a third-party intermediary stage negotiations, and elaborate the framework by attending to the strategic navigational efforts of network alignment through negotiations.     

Circular economy in Latin America: A systematic literature review

The purpose of this study is to identify circular economy concept trends of Latin America with regards to Europe, in which a systematic review of literature (SRL) was made using Scopus data in order to define the search, to select the relevant articles, and to analyze the results. Seventy‐one articles from Scopus were reviewed, and the analysis was complemented by the analysis with 57 documents from other scientific Web browsers such as Mendeley, Scopus, Academic Google, ScienceDirect, and SciELo which sum a total of 128 documents which the majority have come from Europe. Main concepts were identified, barriers and trends. The main conclusion was which the current concept is not very clear; in spite of Europe knows that limitation, Latin America is making the same mistake implementation.     

Integrating circular business models and development tools in the circular economy transition process: A firm‐level framework

Along with the concept of circular economy growing worldwide, circular business models (CBMs) have been receiving ever greater attention in both the business sector and academia. However, the existing literature on the CBM is scattered and fragmented; this study offers an integrated firm‐level framework to link CBM typologies, the circular economy transition process, and relevant tools for CBM development and clarifies the positioning and roles of those tools in the process. In response to the fragmentation issue, results of this study are presented in three subtopics: (a) CBM typologies and archetypes, (b) transition guidelines, and (c) major analytical tools for CBM research. The roles and functions of CBM typologies and tools were integrated in different stages of the transition process, and the challenges and shortfalls for CBM research in the various stages were identified. This work lays the foundation for future operational studies.     

Sustainable development and circular economy: The role of institutional promotion on circular consumption and market competitiveness from a multistakeholder engagement approach

The transition from a linear economy to a circular economy (CE) is a real challenge to achieve long‐term sustainability. To push CE in the market, institutional promotion could become a key driver to positively impact both circular consumption and the competitiveness of the market. This paper analyzes the influence that soft and hard initiatives have on circular consumption and market competitiveness. Based on a survey of 1,281 respondents from different types of stakeholders, structural equations modeling statistical analysis was run. Results show that soft initiatives support the achievement of both objectives, whereas hard ones only influence greater circular consumption. However, the perception of the different stakeholders considered is very heterogeneous. It is indicative that not all institutional promotion initiatives are effective. Thus, institutions should guide, in an adequate and differentiated manner, their efforts to promote CE and sustainable development depending on the stakeholder they are targeting.     

Circular economy to enhance sustainability of small and medium‐sized enterprises

The circular economy (CE) represents a major paradigm shift of moving from the concepts of linear to circular supply chains across multiple industries. Although some aspects of CE adoption within industrial supply chains have been researched extensively (particularly addressing challenges of design, implementation, and operations), the research that relates CE practices with sustainability performance to reveal the current state of CE practices within small and medium‐sized enterprises (SMEs) is scant. The aim of this research was to facilitate SMEs to achieve greater sustainability through CE implementation. This research addresses three research questions—How are CE fields of action related to sustainability performance? What are the issues, challenges, and opportunities of adopting CE in SMEs? And what key strategies, resources, and competences facilitate effective implementation of CE in SMEs? This study adopts a mixed method approach (qualitative and quantitative) using survey research, focus group, and case studies; 130 randomly selected SMEs within the Midlands of the United Kingdom have been surveyed, and the responses are analysed using statistical tools along with findings from focus groups and case studies. The study reveals that all CE fields of action (take, make, distribute, use, and recover) of SMEs are correlated to economic performance, but only make and use are related to environmental and social performance. The study further derives strategies, resources, and competences for achieving sustainability across all the CE field of actions. Additionally, this research reveals the issues and challenges, strategies, resources, and competences required for implementing CE in SMEs.     

Sustainable Growth: A Circular Economy Perspective

Abstract:

Since the Brundtland Report was released in 1987, research on sustainable development has become an urgent issue of common concern. To meet the present consumption without compromising the needs of future generations, it is essential for society to practice the “don’t waste waste” principle and to promote sustainable growth. As this article illustrates, sustainable growth can be understood as an institutional arrangement of regenerating circular GDP in a sustainable manner. In the circular economy system, sustainable growth is not only theoretically feasible, but also looks very promising. To promote sustainable consumption and investment, a certain degree of institutional planning (i.e., a process of progressive institutional change) initiated by a community or a government is necessary. Sustainable growth is, in essence, a dynamic process of mutually-interacting socioeconomic activities of learning and training in sustainability issues, and this requires great effort as well as the active participation of people from all walks of life.     

Performance evaluation of reverse logistics in food supply chains in a circular economy using system dynamics

Supply chains are composed of multiple stakeholders who have complex interrelationships. In addition, the forward and reverse flow of materials, information, human resources, and finance occurs among different stakeholders in closing the loop of supply chains. Reverse logistics (RL) activities are gaining importance in terms of size and quantity due to both economic and environmental concerns. These flows in RL in supply chains are both dynamic and complex in nature. Further, the environmental impact of RL activities has barely been considered in holistic way in available literature. In this study, a system dynamics model has been developed to analyze and comprehend the green performance of RL activities by predicting the environmental impact of RL activities. The proposed model has been validated by a case study in the context of a food supply chain. In the company where the case study is carried out, the environmental effects of RL activities have been analyzed. These activities in a food supply chain in terms of CO₂ (carbon dioxide), NO_x (nitrogen oxide), SO₂ (sulfur dioxide), and PM (particulate matter) emissions have been predicted through a system dynamics model for the years 2020 to 2024. The proposed methodology is applied in a food supply context, a major player in retail business, especially in emerging economies. According to our findings, the RL activities in a food supply chain can significantly contribute to green performance management by minimizing food waste and loss; hence, the environmental impacts of such activities should be closely examined from a managerial perspective.
