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 use of renewable energy and recycling products is one of the main achievements of organizations. The circular economy (CE) is a new concept which evolves out of a new management assumption in organizations based on recycling, reuse, and repurposing of products. The circular economy provides a framework for facing challenges and a guide for rethinking and redesigning the future. This chapter analyzes the Portuguese market for circular economy organizations based on discussion of the CE conceptual model. The circular economy is expected to contribute positively by introducing new methodologies for the production of raw materials, with new production processes and giving value to eco products. The challenge for Portuguese organizations is to create management “vectors” which promote networking innovation, labor, capital, and eco products. Overall, the conceptual model presented gives importance to Portuguese business decision making for sustainable consumption, which provides advancements in business for the green supply chain.

The growing number of Electric Vehicles poses a serious challenge at the end-of-life for battery manufacturers and recyclers. Manufacturers need access to strategic or critical materials for the production of a battery system. Recycling of end-of-life electric vehicle batteries may ensure a constant supply of critical materials, thereby closing the material cycle in the context of a circular economy. However, the resource-use per cell and thus its chemistry is constantly changing, due to supply disruption or sharply rising costs of certain raw materials along with higher performance expectations from electric vehicle-batteries. It is vital to further explore the nickel-rich cathodes, as they promise to overcome the resource and cost problems. With this study, we aim to analyze the expected development of dominant cell chemistries of Lithium-Ion Batteries until 2030, followed by an analysis of the raw materials availability. This is accomplished with the help of research studies and additional experts’ survey which defines the scenarios to estimate the battery chemistry evolution and the effect it has on a circular economy. In our results, we will discuss the annual demand for global e-mobility by 2030 and the impact of Nickel-Manganese-Cobalt based cathode chemistries on a sustainable economy. Estimations beyond 2030 are subject to high uncertainty due to the potential market penetration of innovative technologies that are currently under research (e.g. solid-state Lithium-Ion and/or sodium-based batteries).

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.

Words like palimpsest or heterotopia do not belong to the working vocabulary of materials or engineering sciences: they are used in Social Sciences and Humanities (SSH). A palimpsest is a manuscript written on an older document, the text of which has been erased. Heterotopia is a young word forged by Michel Foucault in 1967 to describe a closed space, the boundaries of which mark a discontinuity in terms of behavior: a jail or a monastery are thus a heterotopia. The Circular Economy (CE) is an essential concept in the framework of the ecological transition, pulled by a series of converging economic, ecological and political drivers. It is usually described as the adoption of a circular model of production to replace the “linear model”, but also as the new buzzword to describe material efficiency, the 3-R rule, the zero-waste ideal, the concepts of lean or frugal design or their reformulation by the Ellen Macarthur Foundation, as a societal challenge and an ethical necessity. Materials producers claim that they have been practicing the Circular Economy since long before the expression was ever invented, thus à la Monsieur Jourdain, etc. The point of this paper is to describe the Circular Economy as a palimpsest and as a heterotopia and to use the metaphors, if indeed they are only metaphors, to highlight some of the less obvious features of the CE. A palimpsest is a parchment or a papyrus, which is used several times to support a series of consecutive texts. Secondary raw materials are like a palimpsest, because there are retrieved from a previous life and used again in a second life: a new artefact made from that material is like a new text written on/with this material – a metaphor also used, mutatis mutandis, in expressions like 3-D printing or laser scribing. Some interesting features of the CE pointed out by the metaphor: a the palimpsest can be used several times, like a material can be recycled several times; the concept of the palimpsest posits that the parchment is somehow more important than the text that is written on it, therefore a material is more important than the goods that are made of it; the palimpsest was used before the invention of paper and, similarly, the Circular Economy was the standard model before mass production of cheap consumer goods imposed the so-called “linear model”; a palimpsest keeps a fragmented memory of the past, in the same way as recycled material maintains a link to its past lives, through its composition in tramp elements. Examples of heterotopia are a prison or a cemetery. The Circular Economy defines a space where a particular material/element exists in its various avatars, impersonations and reincarnations and this may tentatively be worked out as a heterotopia. This is a more complex endeavor than discussing the palimpsest metaphor, but a potentially more fruitful one. Foucault has provided criteria defining heterotopia which can help us explore the analogy: particularly the point that such a space is either a space of illusion or a space of perfection. This analysis is original because it hybridizes materials and SSH concepts and thus fits with the exploration of the frontier between materials and society that SAM conferences are concerned about.

Mineral resources are life and driving force of the European Union. It is gaining awareness not only in the EU dependent on imports, but also in the world. In the context of the growing population and the growing demands of economies for natural resources, this type of material management has a significant negative impact on the environment. The main aim of the study was to justify the model of circular economy on the national level, based on the disparities between the regions of Slovak republic. To meet the objective, mostly one-factor analysis was implemented. The circular model, which is based on the partial replacement of primary raw materials by secondary ones, should, on the one hand, limit the depletion of natural resources and, on the other hand, reduce the amount of waste produced. The presented work focuses on the issue of sustainable development, which is closely related to the circular economy, and then explains the circular economy model, including the differences from the linear arrangement and possible obstacles to its implementation for the specific conditions of the Slovak republic. From the results, it is clear that the proposed circular model would be helpful to improve the inefficiencies and disparities on the regional and national level.

The Circular Economy (CE) is gaining increasing attention among businesses, policymakers and academia, and across research disciplines. While the concept’s strong diffusion may be considered its main strength, it has also contributed to the emergence of many different understandings and definitions, which may hinder or slow down its success. Specifically, despite growing attention, the role of the consumption side in the CE remains a largely under-researched topic. In the present review, we first search the literature by means of snowball mapping and a systematic key-word strategy, and then critically analyze the identified sources in order to elucidate the fundamental elements that should characterize consumption in a CE. We extract two pillars, directly from definition, that should be at the nucleus of future research on consumption in the CE: (1) the hierarchical nature of circular strategies, with “reduce” being preferred to all other strategies; and (2) the inadequacy of defining the CE only through its loops or strategies without considering its goal of attaining sustainable development. Moreover, the discussion is placed within the extant consumer research streams deemed relevant, in order to bridge these with the context of the CE. We highlight limitations of said research streams regarding their typical focus on the quality (and not the quantity) of consumption, the lack of heterogeneity in the theories and data collection methods employed, and the non-impact-based instruments typically used to measure consumption behaviors. We show how these limitations have contributed to the emergence of the intention–behavior gap, a phenomenon extant studies identify as key to overcome for encouraging sustainable consumption practices. In particular, we focus the analysis on the intention–behavior gap in order to: (1) establish the state-of-the-art; and (2) uncover avenues for future research addressing extant limitations.

Introduction. This case study examines the economic justification for the implementation of a circular economy. The case study is structured in 2 parts. The first part describes the principles of circular economy and business models, covering the theoretical basis of this study. The theoretical basis includes a description of the principles of circular economy and the possible implementation of these principles in business operations. The second part evaluates the impact of the introduction of circular economy principles and business model on the company's financial performance and company value. The methods used are economic evaluation and investment decision methods and financial analysis, modeling and forecasting. The limitations are the research based on one company and the fact that the financial statement for 2019 was not submitted at the time of writing; however the results obtained are applicable to other companies and industries. The principles of circular economics and business models described in this case study can serve as a example for companies considering implementing the principles of circular economy in business operations. Aim and tasks. The purpose of the study is to determine what the principles of circular economy are, how to implement them in business and how their implementation affects business results and company value. Following tasks have been defined in order to achieve the aim: describe the principles of circular economy, business and financing models; to analyze the business models of the circular economy in Latvia and in the world and to evaluate the impact of the implementation of the principles of circular economy and business model on the company's financial indicators and the company's value. Results. Evaluating the investments made by the company AS “Cēsu Alus” and the planned investment projects related to the modernization of production equipment and improvement of efficiency, it can be concluded that the implementation of circular economy investment projects will be profitable. The company has opportunities to continue the investment project program; moreover, based on the experience of similar companies studied, AS “Cēsu Alus” can create additional revenue streams for the company when adopting circular economy principles. Conclusions. Investing the company's funds in investment projects designed to improve the company's efficiency, ensuring resource savings and efficient use, which in turn leads to financial savings, the company's value increases significantly, thus concluding that circular economy investment projects that save resources and improve the efficiency of the company will make the greatest contribution to increasing the value of the company.

In the world, the theory of the circular economy and its formation in the real economic system is rapidly developing. Many international organizations (OECD, EU) and countries already have their programs for developing such an economy. The article emphasizes that the practical implementation of the concept of “best available technologies” is vital for the transformation of the current linear model of the economy in many countries, including Russia. In Russia, there are many obstacles to the formation of a circular economy; the inertia of the existing export-raw material model is excellent, which is unsustainable and linear. A dangerous trend is the growth of waste intensity at the macro level. The article analyzes and adapts for Russia the UN Sustainable Development Goals directly related to the circular economy, proposes and quantifies key indicators. In the field of quantitative indicators, four areas have been identified for the development of crucial indicators set for the circular economy in Russia. An author’s formula for structuring the consumption of natural resources taking into account technological efficiency and waste is proposed. The importance of using the proposed toolkit of natural-product verticals combining primary natural resources / raw materials with final consumption and allowing us to estimate the size of the lost primary natural resources is emphasized. The indicators of waste management, in combination with production and consumption systems, are analyzed. For a circular economy, it is fundamentally important to calculate the resource and material intensity indicators of various sectors and their weight in the gross product, which will allow to assess the impact of potential structural changes on waste generation and conduct a comparative analysis with the corresponding indicators of other countries.

Internet of Things (IoT) can help to pave the way to the circular economy and to a more sustainable world by enabling the digitalization of many operations and processes, such as water distribution, preventive maintenance, or smart manufacturing. Paradoxically, IoT technologies and paradigms such as edge computing, although they have a huge potential for the digital transition towards sustainability, they are not yet contributing to the sustainable development of the IoT sector itself. In fact, such a sector has a significant carbon footprint due to the use of scarce raw materials and its energy consumption in manufacturing, operating, and recycling processes. To tackle these issues, the Green IoT (G-IoT) paradigm has emerged as a research area to reduce such carbon footprint; however, its sustainable vision collides directly with the advent of Edge Artificial Intelligence (Edge AI), which imposes the consumption of additional energy. This article deals with this problem by exploring the different aspects that impact the design and development of Edge-AI G-IoT systems. Moreover, it presents a practical Industry 5.0 use case that illustrates the different concepts analyzed throughout the article. Specifically, the proposed scenario consists in an Industry 5.0 smart workshop that looks for improving operator safety and operation tracking. Such an application case makes use of a mist computing architecture composed of AI-enabled IoT nodes. After describing the application case, it is evaluated its energy consumption and it is analyzed the impact on the carbon footprint that it may have on different countries. Overall, this article provides guidelines that will help future developers to face the challenges that will arise when creating the next generation of Edge-AI G-IoT systems.
