This study aims to analyse the publication stage on the transition to a circular economy (CE) from the perspective of the isomorphic mechanisms of the new institutional theory (NIT).

The authors conducted a systematic literature review using the Methodi Ordinatio protocol across four databases, resulting in the analysis of 17 articles.

The authors identified a network of CE studies among universities in different countries. As a main result, this study contributed to demonstrating the diversity of approaches available to investigate CE, the importance of stakeholders in the process of transition from linear economy to CE and the means for the transition to CE, as well as the need for future studies covering the detailed analysis of the transition process and the comparison of the evolution of the states/regions of the same country in this process.

The study analyses and summarises the existing literature on CE through the lens of the NIT, analysing the stage of publication based on the phases of implementation of CE (micro, meso and macro). With a research agenda, it presents the current gaps, providing a possible direction for future studies.

In this paper, the authors adopt the theory of the circular economy to study the transitions that take place in three case studies in Mexico and Ecuador. The work is aimed to systematize a circular economy assessment tool that fosters opportunities for improvement in business practices.

The methodology is based on a descriptive quantitative analysis, where a checklist is made with 91 items and nine study variables. This is from the study of the bibliography and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable according to the sensitivity by the Lek’s profile method.

It is based on a descriptive quantitative analysis, where a checklist with 91 items and nine study variables is made, defined from a bibliographic study and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable based on sensitivity.

The application of the tool requires prior knowledge of the circular economy approach, which is why specialized personnel are needed for its application. This makes research more expensive in time and human resources.

The practical and methodological contribution of this work lies in the feasibility of the tool that favors the definition of improvement actions for the implementation contribution to the circular economy in business practices.

The social contribution is framed in the gradual transition to circular economy approaches in underdeveloped countries.

The use of the neural network method to predict the level of circular economy in a case study allows making decisions in a predictive way. This encourages the development of the circular economy according to the context needs.

Las limitaciones se centran en la necesidad de conocer el tema de la economía circular para la aplicación de la herramienta. Por lo tanto, se necesita capacitación antes de comenzar un nuevo estudio. Esto encarece la investigación en tiempo y recursos humanos.

El aporte práctico y metodológico de este trabajo radica en la viabilidad de la herramienta que favorece la definición de acciones de mejora para la contribución de la implementación a la economía circular en las prácticas empresariales.

La contribución social es parte de la transición gradual a enfoques de economía circular en países subdesarrollados.

In total, 19 practices of circular economy divided into three groups, internal environmental management, ecological design and investment recovery were studied in a local network composed of small companies and individual entrepreneurs related to common product and by-product flows. The paper aims to discuss these issues.

This research presents an applied nature, is characterized as exploratory and adopted the case study as a technical procedure using sources and methods of data collection. The primary data were collected through direct observation of the processes and semi-structured interviews with managers and owners.

The most widespread practices are related to product design. However, in most cases, the implementation was punctual and did not present continuous and corresponding actions, which highlights the embryonic contours of European Commission (EC) in the observed network. The practices from the management category were less observed, which revels the environmental variable is not included in the strategic business planning.

The research documents the application of CE practices in a local network and brings this current paradigm shift to the Brazilian context.

To overcome barriers to the implementation of EC practices, it is suggested to restructure commercial relations, to formulate public policies and to develop infrastructures that facilitate the materiality of flows and the market.

The study highlights the need of public policies that promotes cross-sectoral cooperation in accordance with NSWP objectives.

Despite the focus on EC implemented practices this study offers a framework of the research routes on the main barriers and suggests actions to overcome the challenges in the transition from the economy to the circular model.

This research endeavours to achieve two primary objectives within the context of regenerative tourism (RT). Firstly, the study aims to explore the trends and conceptual structure of RT, mapping its scope through a bibliometric analysis. Building upon the knowledge garnered from the initial exploration, the second aim is to establish a regenerative stakeholder framework for tourism, grounded in biodiversity.

Data from the Web of Science (WoS) and Scopus were collected for a bibliometric analysis in this research. The merged database found a total of 42 publications.

Based on bibliometric analysis in Biblioshiny, six indicators were identified (e.g. the annual publications, the most cited studies, productive countries, journals and thematic map). Furthermore, the authors' keyword analysis was conducted using the VOSviewer software package, revealing four clusters, namely, stakeholders, ecotourism, circular economy and climate change.

This research's scope is restricted to Scopus and WoS through 21 February 2024. Future research could broaden RT perspectives through different databases.

The research offers the RT stakeholder framework developed based on the RT and stakeholder theory.

This research advances awareness of the Earth's current needs and the literature on tourism stakeholders by establishing a biodiversity-based regenerative stakeholders' framework in which both human and non-human stakeholders can coexist.

The shift toward a circular economy (CE) represents a collaborative endeavor necessitating the presence of efficient frameworks, conducive contexts and a common comprehension. This research serves as a pivotal stride towards this goal, presenting an exclusive prospect for the investigation and fusion of these frameworks, with particular emphasis on the Quintuple Helix Model (5HM), into a unified theoretical framework that underscores the core principles of the CE. This study is centered on three pivotal questions aimed at decoding the CE transition in specific regional settings.

Adopting an abductive approach firmly anchored in a two-stage qualitative process, this study specifically merges the foundational principles from institutional theory, entrepreneurship literature and CE frameworks to provide insights into the dynamics of circular ecosystems, with a specific focus on the Huelva region in Spain.

The findings demonstrate significant potential in the CE, ranging from the integration of product and service systems to innovations in eco-industrial practices. Yet, a notable deficiency exists: the absence of institutional entrepreneurs, highlighting the essential role that universities can play. As recognized centers of innovation, universities are suggested to be key contributors to the transformation toward a CE, aligning with their societal and economic responsibilities.

This study highlights the importance of managing relationships with entities like SMEs and policymakers or academia for effective CE adoption. Policymakers can refine strategies based on the research’s insights, while the impact of university-driven circular ecosystems on sustainable societies is another crucial area for research.

The sustainability models cited in CE literature may not be comprehensive enough to prevent problem shifting, and it can be argued that they lack a sound theoretical and conceptual basis. Furthermore, the connections between sustainability objectives and the three levels of the CE operating system remain vague. Additionally, there is insufficient information on how regions foster the involvement of the environment in fivefold helix cooperation and how this impacts the CE.

The paper presents the concept of Solidarity Economy proposed by the Austrian-Brazilian economist and professor Paul Singer who passed away in 2018 at age 86 years in his home in São Paulo. Singer arrived at the concept of Solidarity Economy by mixing utopian socialist thought originated in Europe during the Industrial Revolution with the wisdom of Latin American working people to find alternative paths to the capitalist economic system. Following the teachings of Paul Singer, we, as practitioners and academics, report the first stage of the formation of a popular cooperative in the sector of recycling that occurred between 2019 and 2021 in the Town of Goiás, Goiás, Brazil. Our analysis of this collective endeavour leads to two main lessons: first, Solidarity Economy is an even broader proposal of an alternative to the capitalist economy than Paul Singer imagined, because its roots are not restricted to the European cooperativism of the nineteenth century, and second, economics must be taught in more popular way because the most urgent economic problems affect primarily the working people.

The purpose of the article is to analyze the chain of electrical and electronic equipment (EEE) and its waste (WEEE), within the product chain of Recicladora Urbana (Reurbi), and its interaction with the circular economy.

Exploratory research with a qualitative approach, based on the study case method, was conducted. The following stages were carried out: definition of the study object; bibliographic survey; documentary survey; technical visit to Reurbi; contacts with experts; creation of research instruments and research execution.

The main recipients of remanufactured EEE are third sector organizations that run social programs and schools with few financial resources. Recycling firms receive parts and components from the WEEE handled by Reurbi.

The authors only addressed the WEEE reverse remanufacturing chain of Reurbi; therefore, the authors cannot extend the results to an industrial sector.

One practical contribution is disclosing the remanufacturing processes of EEE and the recycling processes of its waste, fostered by the National Solid Waste Policy (PNRS), under a circular economy policy.

There is a large market potential for reverse logistics of WEEE and end-of-life EEE as a source of raw material, which is yet to be explored in Brazil, for creating new jobs and revenue.

The publication of articles with the main reflections from the results can provide new discussions and provide opportunities for new studies regarding the Brazilian Solid Waste Policy.

The purpose of this paper is to analyze circular business models of Brazilian companies.

The authors analyzed 105 business models of adopting companies from the perspective of the circularity of resources. These were classified as analytical sector category, business model design aligned with sustainability, sustainable practices adopted, level of maturity of business models and determinants of the circularity of resources.

The results show that companies belonging to the service sector predominate, which, above all, offer the virtualization of processes, sharing, ecological products, socially responsible and emphasis on recycling. Of these, 92.38 percent were already aligned with the sustainability assumptions, which contribute decisively to the operationalization in a circular perspective. Therefore, the materialization of the circular economy (CE) in Brazil is occurring, although there is potential for a stronger engagement with the determinants of the CE, especially in the perspective of the biological cycle and in the short cycles of technical levels.

In addition, the authors promote advances in the maturity levels of business models to optimize the optimal level, where processes are predictable, critically analyzed and continuously improved.

The purpose is to conduct a systematic review of circular water management and its role in improving water availability amid increased demand and decreased supply.

A systematic literature review was implemented, which helped in the identification, selection and critical appraisal of the various research to answer the research question. It was guided by the Preferred Reporting Items for Systematic Reviews (PRISMA) statement. The review was conducted mainly on Web of Science and Scopus databases between November 20 and December 8, 2022, with search strategies involving free-text searching, phrase searching, truncation and Boolean operators.

The search process yielded 46 articles exploring circular water management. The findings reveal that circular water management offers more promise than linear or business-as-usual approaches. There are various circular water management models, although most of them emphasize a shift from the “take, make, consume and waste” principles. Contrarily, the success of the circular water management framework hinges on its ability to embrace resilience based on changing environmental conditions. Furthermore, the model focuses on improving inclusiveness with various stakeholders working together to improve water management.

The research is the first of its kind as it identifies a critical gap, the imperative need to develop a universal framework that can significantly advance the comprehension of circular water management.

There is no literature that sought the revision and integration of ecological modernization of theory (EMT) and circular economy (CE). This article aims to answer the questions: How have companies developed circular economy practices within their operations? Why have companies invested in circular economy practices? Based on the answers to these questions, it would be possible to understand how the assumptions of EMT explain the adoption of CE practices.

The research method is based on multiple case studies with Brazilian craft brewery companies.

Companies studied have pursed the adoption of circular economy practices, but the full potential of the use of biological cycles within their processes of production has been hampered by the lack of external policies and clear governance toward circular economy. Thus, pollution prevention policies may be an important driver for organizations be able to advance in circular economy practices.

Research limitations are coverage only of organizations located in an emerging country. A second limitation is that the data saturation was partially achieved in some of the analyzed cases, especially by the limitation of the time period surveyed (transversal research). The longitudinal evaluation is timely for circular economy surveys.

The formulation of a regulatory framework through a participative, interactive and decentralized process, capable of delegating responsibilities and incentives to all entities, to contemplate a tax restructuring for the alcoholic beverage sector, could corroborate to create a new standard of action for the sector.

This document highlights how the principles of ecological modernization can contribute to the advancement of the circular economy. The understanding can help in the design of processes that provide circular and sustainable operations as a social good in a effective value.

The principles from EMT, such as the development of an institutional environment towards corporate environmental proactive, could enhance the adoption of circular economy practices within the brewery sector. Despite of the class association of the brewery sector has supported the companies studied to move forward in other matters, a clear governance is necessary to guide organizations towards circular economy practices.
