Abstract In the article, the authors describe, using the example of a selected class of technical means, their concept of replacing the “classical” linear management (exploitation) model with a circular economy (CE) model. An example of an object for which the authors plan to test the feasibility of the concept presented above is a household washing machine driven by a DC motor. The description of this object included in the article considers its complexity and multiplicity of assemblies, sub-assemblies, and elements. The DC electric motor driving the washing machine was considered the most important from the point of view of the created model, especially in terms of the possibility of maintenance and repair. For such an engine, the article presents the maintenance and disposal model as elements of the concept of building a ‘circular’ business model. The authors assumed that the formal basis for such a model would be the so-called circular model. The methodology and plan of the research carried out at Super Asia washing machine company in Pakistan were introduced, and the research results were shown. With the use of these results, an attempt was made to assess the requirements that the application of the CE business model places on manufacturers of a selected class of devices, both in their manufacture, repair, sharing and dematerialization. The concept of further research is described at the end of the article.

A Economia Circular promove práticas de consumo sustentável no setor de vestuário e produtos de segunda-mão, proporcionando reduzir os poluentes e garantir durabilidade dos componentes sem a necessidade de retirar matéria-prima da natureza. As plataformas online podem ser aliadas deste modelo de negócio, pois proporcionam acesso rápido e amplo a esses produtos. O objetivo deste estudo é analisar como os consumidores identificam e percebem as práticas de consumo de produtos de segunda mão, a partir da concepção do modelo de negócios circulares. Foi realizada uma pesquisa com aplicação de questionário eletrônico. Os resultados demonstram que existem práticas de consumo seguindo o modelo circular, mesmo que o conceito se encontre ainda implícito aos negócios de produtos de segunda mão. A preocupação dos indivíduos quanto ao impacto que o consumo exacerbado de produtos pode causar ao meio ambiente e a sustentabilidade do ecossistema é evidenciada, bem como a percepção da busca por meios de consumo que não agridam esse ecossistema. No entanto, essa percepção pelo propósito central do modelo de negócios circulares ainda não está presente de forma consciente quanto aos benefícios que a adoção do modelo de negócios circular pode ofertar, tanto para o meio ambiente, quanto para a sociedade como um todo. ABSTRACTThe Circular Economy promotes sustainable consumption practices in the clothing and second-hand products sector, provides a reduction of the pollutants and ensures component durability without the need to remove raw materials from nature. Online platforms can be associated with this type of business, as they provide quick and wide access to these products. The purpose of this study is to analyze how consumers identify and perceive practices of second-hand products consumption, based on the design of the circular business model. A survey was conducted using an electronic questionnaire. The results demonstrate the existence of consumption practices following the circular model, even though the concept is still implicit to the business of second-hand products. The concern of the individuals about the impact that the excessive consumption of products can cause to the environment and ecosystem sustainability is evidenced, as well as the perception of the pursuit for means of consumption that do not harm this ecosystem. However, this perception for the main purpose of the circular business model is, yet, not consciously present as to the benefits that the adoption of a circular business model can offer, both for the environment and for society as a whole.

The shift from the existing linear model of the economy to a circular model is gaining traction across business entities, nationally and globally. Minimal studies have been done that would support the circular transition for a business from an existing linear model. There is a significant gap between the formulation and implementation of circular strategies in business. This literature review explores the preexisting concepts of the business model canvas (BMC) and Value Hill tool for the implementation of circular strategies in a business by determining a Good Point for Transition (GPT). The favorable condition, where a business can transition from a linear economy (LE) to a circular economy (CE) is defined as a GPT. This study suggests a three-step generic process that would provide a company with clarity on how to incorporate circular strategies into their structure. Firstly, this review paper defines and elaborates upon the business model canvas (BMC) based on the prior work of Osterwalder and Pigneur (2010) and Lewandowski (2016). Secondly, it analyzes the Value Hill diagram, a strategic tool for circular activities, that a business can use upon implementation of a circular model (Achterberg et al., 2016). Finally, this work will indicate how a circular strategy can be selected on the basis of assessment of the BMC and Value Hill diagram of a business. For a better understanding of the process, IKEA's initiatives for circular strategies are used in the study. The paper concludes with a three-step generic model for determining GPT and emphasizes that the adoption of circular strategies for companies depends upon the circular expertise and resources they and their value chain partners have across the Value Hill diagram. Keywords: circular economy, circular strategies, circular business model canvas, value hill diagram, circular transitions

One of the major issues the agri-food supply chains is the considerable production of by-products, which are mostly discarded as wastes and dangerously landfilled. This problem is particularly acute in the coffee supply chain: coffee cultivation generates by-products and in quantities which are potentially dangerous for the environment. A circular economy business model aimed at the recovery of these by-products may represent an interesting solution in terms of environmental, social, and economic sustainability. The goal of this paper was to provide teachers and educators with case material on circular business models that can be used for problem-based learning and case-based learning activities. The proposed case was built to address a real-world problematic situation related to the coffee supply chain. From a theoretical point of view, this study contributes to the literature on circular economy business models by providing a case study developed in the context of a developing country. Furthermore, the research entails practical implications since it shows managers and startuppers how to map a circular business model in all its components under the guidance of a conceptual framework.

Upon the development of a linear economy, global enterprises are facing resource depletion, ecological collapse, and unsustainable economic growth, and the living environment is facing ordeals as well. Taiwan’s resources are extremely dependent on imports; hence the need for change in the thinking of economic development is arising. The purpose of this study is, based on the concept of circular economy, to discuss the business model and anticipated benefits of Chyhjiun Jewelry Co. Ltd., by using the method of expert interview, participant observation, and method of secondary data collection with the ReSOLVE framework. The results of the study found the developable ReSOLVE business model of the target company Chyhjiun Jewelry in our case study; the ReSOLVE business model includes the use of renewable energy, maintenance and repair services, modular product design, a recovery mechanism, a virtual online shopping platform, and 3D printing technologies. The model established enterprise recycling model as well as the benefits of green management, of which the research results could reduce costs, help the company in exercising its corporate social responsibility, add value to the brand, and generate anticipated benefits arising from other enterprises’ follow-up actions.

The prevailing need for a more sustainable management of natural resources depends not only on the decisions made by governments and the will of the population, but also on the knowledge of the role of energy in our society and the relevance of preserving natural resources. In this sense, critical work is being done to instill key concepts—such as the circular economy and sustainable energy—in higher education institutions. In this way, it is expected that future professionals and managers will be aware of the importance of energy optimization, and will learn a series of computational methods that can support the decision-making process. In the context of higher education, this paper reviews the main trends and challenges related to the concepts of circular economy and sustainable energy. Besides, we analyze the role of simulation and serious games as a learning tool for the aforementioned concepts. Finally, the paper provides insights and discusses open research opportunities regarding the use of these computational tools to incorporate circular economy concepts in higher education degrees. Our findings show that, while efforts are being made to include these concepts in current programs, there is still much work to be done, especially from the point of view of university management. In addition, the analysis of the teaching methodologies analyzed shows that, although their implementation has been successful in favoring the active learning of students, their use (especially that of serious games) is not yet widespread.

This study aims at providing a systematic and critical review on the state of the art of life cycle applications from the circular economy point of view. In particular, the main objective is to understand how researchers adopt life cycle approaches for the measurement of the empirical circular pathways of agri-food systems along with the overall lifespan. To perform the literature review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol was considered to conduct a review by qualitative synthesis. Specifically, an evaluation matrix has been set up to gather and synthesize research evidence, by classifying papers according to several integrated criteria. The literature search was carried out employing scientific databases. The findings highlight that 52 case studies out of 84 (62% of the total) use stand-alone life cycle assessment (LCA) to evaluate the benefits/impacts of circular economy (CE) strategies. In contrast, only eight studies (9.5%) deal with the life cycle costing (LCC) approach combined with other analyses while no paper deals with the social life cycle assessment (S-LCA) methodology. Global warming potential, eutrophication (for marine, freshwater, and terrestrial ecosystems), human toxicity, and ecotoxicity results are the most common LCA indicators applied. Only a few articles deal with the CE assessment through specific indicators. We argue that experts in life cycle methodologies must strive to adopt some key elements to ensure that the results obtained fit perfectly with the measurements of circularity and that these can even be largely based on a common basis.

Efficient sustainability management requires the use of tools which allow material, technological and construction variants to be quantified, measured or compared. These tools can be used as a powerful marketing aid and as support for the transition to “circular economy”. Life Cycle Assessment (LCA) procedures are also used, aside from other approaches. LCA is a method that evaluates the life cycle of a structure from the point of view of its impact on the environment. Consideration is given also to energy and raw material costs, as well as to environmental impact throughout the life cycle - e.g. due to emissions. The paper focuses on the quantification of sustainability connected with the use of various types of concrete with regard to their resistance to degradation. Sustainability coefficients are determined using information regarding service life and "eco-costs". The aim is to propose a suitable methodology which can simplify decision-making in the design and choice of concrete mixes from a wider perspective, i.e. not only with regard to load-bearing capacity or durability.

PurposeDigital innovation and circular business model innovation are two critical enablers of a circular economy. A wide variety of digital technologies such as blockchain, 3D printing, cyber-physical systems, or big data also diverges the applications of digital technologies in circular business models. Given heterogeneous attributes of circular business models and digital technologies, the selections of digital technologies and circular business models might be highly distinctive within and between sectorial contexts. This paper examines digital circular business models in the context of the fashion industry and its multiple actors. This industry as the world’s second polluting industry requires an urgent circular economy (CE) transition with less resource consumption, lower waste emissions and a more stable economy.Design/methodology/approachAn inductive, exploratory multiple-case study method is employed to investigate the ten cases of different sized fashion companies (i.e. large, small medium-sized firm (SME) and startup firms). The comparison across cases is conducted to understand fashion firms' distinct behaviours in adopting various digital circular economy strategies.FindingsThe paper presents three archetypes of digital-based circular business models in the fashion industry: the blockchain-based supply chain model, the service-based model and the pull demand-driven model. Besides incremental innovations, the radical business model and digital innovations as presented in the pull demand-driven model may be crucial to the fashion circular economy transition. The pull demand–driven model may shift the economy from scales to scopes, change the whole process of how the fashion items are forecasted, produced, and used, and reform consumer behaviours. The paths of adopting digital fashion circular business models are also different among large, SMEs and startup fashion firms.Practical implicationsThe study provides business managers with empirical insights on how circular business models (CBMs) should be chosen according to intrinsic business capacities, technological competences and CE strategies. The emerging trends of new fashion markets (e.g. rental, subscription) and consumers' sustainable awareness should be not be neglected. Moreover, besides adopting recycling and reuse strategies, large fashion incumbents consider collaborating with other technology suppliers and startup companies to incubate more radical innovations.Social implicationsAppropriate policies and regulations should be enacted to enable the digital CE transition. Market patterns and consumer acceptances are considered highly challenging to these digital fashion models. A balanced policy on both the demand and supply sides are suggested. The one-side policy may fail CBMs that entail an upside-down collaboration of both producers and consumers. Moreover, it is perhaps time to rethink how to reduce unnecessary new demand rather than repeatedly producing and recycling.Originality/valueThe pace of CE research is lagging far behind the accelerating environmental contamination by the fashion industry. The study aims to narrow the gap between theory and practice to harmonise fashion firms' orchestration and accelerate the transition of the fashion industry towards the CE. This study examines diverse types of digital technologies in different circular business models in a homogeneous context of the fashion industry with heterogeneous firm types.
