“…Therefore, SD is a powerful method to gain insights into the structure of complex and dynamic systems (Franco, 2019; Georgiadis & Besiou, 2008; Sterman, 2000); it supports long‐term, strategic decision‐making (Rebs, Brandenburg, & Seuring, 2019) to model, understand, and discuss real‐world problems. There is a gap in associated literature because no adequate research has been conducted on the environmental impact on RL considering value‐added and non‐value‐added activities with SD.…”

“…Ghisolfi, Chaves, Siman, and Xavier (2017) proposed a model on social inclusion of informal waste pickers into the environmental policy in CLSC in Brazil using SD methodology. Franco (2019) presented an SD model to analyze the systemic effects of combining multiple product design and business model strategies for CLSC in a circular economy, conducting a simulation of system behavior for different model variables. Cao et al (2019) developed an SD model to observe the entire life cycle of an electric‐coal supply chain with reference to a greening energy intensive supply chain.…”

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), NOx (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.

“…To collect the articles in this review, a Scopus search was performed using keyword combinations of the word "circular economy" and the names of the following eight main assessment methods: life cycle assessment, input-output analysis, material flow analysis, emergy/exergy analysis, system dynamics, discrete event simulation, agent-based modeling, and operations research (Figure 1). The industrial ecology and complex systems science fields were chosen based on a preliminary review of the CE literature (Ghali et al, 2017;Merli et al, 2018;Franco, 2019;Moraga et al, 2019;Sassanelli et al, 2019). The selection of keywords for the Scopus search also follows from this preliminary review and is based on the frequency of use and analysis of the methods mentioned in the reviewed publications.…”

“…SD describes a system with stocks, flows, and parameters, while a corresponding set of differential and algebraic equations are solved through a simulation to get insights into the system's dynamics (Filippov, 2004). The method accounts for four characteristics of complex systems: accumulation of stocks, time delays, feedback loops, and non-linearities (Franco, 2019). One strength of SD is that, in addition to quantitative data, it may use qualitative data to generate robust and accurate models (Luna-Reyes and Andersen, 2003).…”

The goal of the circular economy (CE) is to transition from today's take-make-waste linear pattern of production and consumption to a circular system in which the societal value of products, materials, and resources is maximized over time. Yet circularity in and of itself does not ensure social, economic, and environmental performance (i.e., sustainability). Sustainability of CE strategies needs to be measured against their linear counterparts to identify and avoid strategies that increase circularity yet lead to unintended externalities. The state of the practice in quantitatively comparing sustainability impacts of circular to linear systems is one of experimentation with various extant methods developed in other fields and now applied here. While the proliferation of circularity metrics has received considerable attention, to-date, there is no critical review of the methods and combinations of methods that underlie those metrics and that specifically quantify sustainability impacts of circular strategies. Our critical review herein analyzes identified methods according to six criteria: temporal resolution, scope, data requirements, data granularity, capacity for measuring material efficiency potentials, and sustainability completeness. Results suggest that the industrial ecology and complex systems science fields could prove complementary when assessing the sustainability of the transition to a CE. Both fields include quantitative methods differing primarily with regard to their inclusion of temporal aspects and material efficiency potentials. Moreover, operations research methods such as multiple-criteria decision-making (MCDM) may alleviate the common contradictions which often exist between circularity metrics. This review concludes by suggesting guidelines for selecting quantitative methods most appropriate to a particular research question and making the argument that while there are a variety of existing methods, additional research is needed to combine existing methods and develop a more holistic approach for assessing sustainability impacts of CE strategies.

“…Moreover, Franco (2019) stated that strategies for the circular design of products have been developed to increase the service life, facilitating maintenance, as well as to enable the disassembly and reassembly of the products. In this sense, reverse logistics plays an important role in the circular economy process, as stated by Dutta et al (2020) and emphasized by Kuşakcı et al (2020), it represents an alternative to minimize the effects of increased waste production.…”
