“…To further establish the reliability of the analysis, iterations of member checks were conducted in which the interviewees were provided with the transcripts of the interviews to assess the accuracy after the transcription (Buchholz & Rosenthal, 2004). This approach is similar to methods adopted in previous studies (Ezeudu et al, 2021;Gong et al, 2019;Kanda et al, 2021). The investigation plan is described in Table 3.…”

“…Besides having adverse health and environmental implications, the resultant waste from the linear economy model poses a great risk to the sustainable availability of economic resources (Hina et al, 2022). Following the earlier works conducted by scholars on concepts like blue economy (Pauli, 2010), natural capitalism (Hawkens et al, 1999), performance economy (Stahel, 2010), cradle‐to‐cradle (McDonough & Braungart, 2002), industrial ecology (Graedel & Allenby, 1995), and laws of ecology (Commoner, 1971), the CE was conceptualized (Ezeudu et al, 2021). The emergence of the CE acts to address the problem of the linear economy paradigm.…”

Despite the growing understanding that circular business models (CBMs) play a pivotal role in facilitating the transition from a linear to a circular economy, there is a lack of relevant literature on how CBMs can be implemented in businesses in developing countries. This study addresses this significant gap in the literature by revealing the insights and dynamics of the implementation of a CBM in a typical developing economy—Nigeria. A notable business model adopted by breweries and beverage companies in Nigeria—a returnable glass bottle process—was investigated through an in‐depth exploration of six companies in a qualitative case study that involves collecting data through interviews, exploratory field observation, and documented evidence (literature). The study generated empirical‐based evidence on how CBM can be implemented in a business value chain where formal and informal actors co‐exist and interact. It also discloses several barriers and enablers associated with CBM implementation in the context of developing economies. Collaboration, social inclusiveness, waste management, durable product design, and cost reductions are some of the enablers identified in the study. The key barriers are largely external and conspicuously linked to the socio‐economic disadvantages peculiar to developing economies such as the absence of effective legislature, lack of infrastructure, lack of technological innovation, unavailability of finance, and the emergence of large retail stores that operate on a disruptive business model. Finally, the current research provides practical suggestions and recommendations for the appropriate designing and transitioning of CBMs in developing countries' context.

“…Alternatively, a focal actor may also get opportunities for circular economy engagement when other actors in the ecosystem develop and launch hard institutions that favor the transition to a circular economy—a phenomenon that we denote as hard legitimizing . This can happen when governmental bodies launch circular policies, laws, and regulations (Urbinati, Franzò, and Chiaroni 2021) and enforce them (Ezeudu et al 2021). Several studies point out that actors are coerced to contribute to circularity by hard institutions like revised waste tax laws, regulations that impose the implementation of take-back and recycling systems, and policies that make collaboration across the value chain obligatory (Moggi and Dameri 2021; Levänen, Lyytinen, and Gatica 2018).…”

Circular business models (CBMs), such as product-service systems, are rapidly gaining traction in light of a transition to a more circular and sustainable economy. The authors call for a new approach to inform and guide the development and adoption of these CBMs. The main reason is that different actors in the service ecosystems or networks linked to these business models—such as firms, customers, and governmental bodies—may be reluctant to join or even impede the transition to a circular economy. Based upon an abductive analysis of 133 CBM papers with the Motivation-Opportunity-Ability (MOA) framework as organizing structure, the authors theorize about how to achieve “circular economy engagement” ( i.e., an actor’s disposition to embrace CBMs). Specifically, they highlight and illustrate the role of (1) signaling and convincing as motivation-related practices, (2) matching and legitimizing as opportunity-related practices, and (3) supporting and empowering as ability-related practices. The authors provide illustrative cases for each of these practices along with a discussion of the theoretical and practical implications and the remaining challenges—all with the key aim to push the transition to a circular economy forward.

“…In recent years, several attempts have been made to implement the principles of the circular economy in the comprehensive management of urban solid waste [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ], following the guidelines of the European regulations [ 31 ]. Some of these attempts are based on applying mathematical models that allow for optimization and improvement of waste treatment, minimizing disposal in landfills and promoting waste recirculation and recycling.…”

This article introduces M-GRCT, a circular economy decision support model for the design of recyclable waste management systems in low-income municipalities. The model allows for performing calculations on a set of two scenarios integrating a sociocultural dynamics assessment, this being a characteristic feature of this type of municipalities. The model also integrates the analysis of the remaining variables usually addressed in solid waste management schemes while considering topics such as reduction of the carbon footprint due to activities such as the transport of recyclable waste, the generation of leachates, the generation of greenhouse gases and the promotion of an increase in the number of associated recyclers and selective routes. The economic evaluation of the different implementation scenarios is supported by a dynamic tool called DATA4 (a macro-type array accompanied by two control panels programmed in Visual Basic and dashboards by Power BI). M-GRCT constitutes a tool for the promotion of good environmental practices and the identification of strategies for the promotion of local development mechanisms. Results provided by the model contrast with those obtained by traditional linear economy approaches. An illustrative example of the application of the M-GRCT model is shown. The model was used to simulate the municipal solid waste managing system of the municipality of Guateque (Colombia). The results show the importance of integrating both economic and environmental costs to optimally allocate governmental and private resources when the recycling rate is expected to increase in the next 10 years.
