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.

Biowaste Treatment

Lately, the model of circular economy has gained worldwide interest. Within its concept, waste is viewed as a beneficial resource that needs to be re-introduced in the supply chains, which also requires the use of raw materials, energy, and water to be minimized. Undeniably, a strong link exists between the bioeconomy, circular economy, bioproducts, and bioenergy. In this light, in order to promote a circular economy, a range of alternative options and technologies for biowaste exploitation are currently available. In this paper, we propose a generic methodological scheme for the development of small, medium, or large-scale units of alternative biowaste treatment, with an emphasis on the production of bioenergy and other bioproducts. With the use of multi-criteria decision analysis, the model simultaneously considers environmental, economic, and social criteria to support robust decision-making. In order to validate the methodology, the latter was demonstrated in a real-world case study for the development of a facility in the region of Serres, Greece. Based on the proposed methodological scheme, the optimal location of the facility was selected, based on its excellent assessment in criteria related to environmental performance, financial considerations, and local acceptance. Moreover, anaerobic digestion of agricultural residues, together with farming and livestock wastes, was recommended in order to produce bioenergy and bioproducts.

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.

Garment Industry is one of the industries that have dumped a large amount of wasted fabric at least 30-40 kg / month. Wasted fabrics are caused by the process of sewing, hydraulic pumping, and flaws on fabric. Those wastes were not being used for any further utilization. The current work investigated the use of Upcycling, a process to converse waste material to become a new product with higher quality and environmentally friendly value, as a conceptual model in the design process and examined its value for Upcycling product design by looking at a case study project. The concept from the Upcycling framework study was chosen for the investigation in order to evaluate a case study: a wasted fabric lamp. The findings suggest that Upcycling was helpful for improving and developing a wasted fabric lamp throughout the design process: including idea development, decision making, and implementation. Based on the evaluation of 3 design experts, it was found that a wasted fabric lamp is appropriate for using new materials or raw materials that do not cause problems for the environment.

The aim of the paper is to present a review of transnational regulations (global and European) in the field of environmental protection and the circular economy. The paper discusses the regulations proposed in publications and reports of such global organizations and UN Agencies as the United Nations Environmental Program (UNEP), the United Nations Conference for Trade and Development (UNCTAD), the Food and Agriculture Organization (FAO), as well as the World Trade Organization (WTO), and the European Commission as the Executive Body of the European Union. With regard to the WTO, these regulations concern the effects of liberalizing trade in environmental goods and services and environmentally sound technologies. Sustainable development means, above all, protecting the natural environment and reducing excessive dependence on depleting natural resources, including primary raw materials, in the economic sector. This implies the need to implement a new resource‑efficient development model, based on the principles of the circular economy (CE), which has been proposed for several years by transnational organizations. In the CE model, the use of natural resources is minimized, and when a product reaches the end of its useful life, it is reused to create additional new value. This can bring significant economic benefits, contributing to new production methods and new innovative products, growth, and job creation. The topics mentioned above are the main subject of consideration in the presented paper.

Sustainable Consumption And Production

The scarcity of natural resources and the generation of waste without adequate disposal are a worldwide concern related to the linear production model.These characteristics are present in the wood panel production. Faced with this problem, the present study aimed to identify in the literature, circular economy (CE) practices in the waste management of wood panel production processes and the possibilities for implementing new practices that incorporate circularity concepts. A systematic search was conducted to select the most relevant work on the theme. A search was done using the ScienceDirect, Web of Science, and Scopus databases by combining the following keywords: “Circular Economy” (and its possible variations), “Wood-based Panel”, and “Wood Waste”. The results evidenced circular economy practices on waste management already being used by the wood panel industry, besides potential practices to increase circularity. The changes go towards sustainable manufacturing and responsible consumption, which aims to “ensure sustainable consumption and production patterns”. Opportunities range from the extraction of raw materials to the disposal of wood panel waste at the end-of-life. The circular economy model is still recent and the process of transitioning is in its initial phase, as well as scientific research on the theme, mainly regarding the wood panel industry. Studies addressing the circular economy and wood panels are not yet widespread, pointing to a gap yet to be explored. The bibliographic review allowed identifying the existence of potential applications of circular economy in the wood panel industry; yet, this piece of research points to a broad field of exploration.

IntroductionEntrepreneurs are individuals or group of individuals who invest capital, organize and direct business and industrial units. An entrepreneur assembles, coordinates and directs various factors of production namely land, labor, capital and other materials. "An entrepreneur initiates ventures, employs workers, organizes production, develops markets and influences the development of managerial thoughts" (Shrestha, 1982:11). As stated by Higgins "Entrepreneurship is meant the function of seeing investment and production opportunities, organizing an enterprise to undertake a new production process, raising capital, hiring labor, arranging for the supply of raw materials, finding a site and combining these factors of production into a going concern, introducing new techniques and selecting top managers for day to day operation" (Higgins, 1966:88). The elements common to all of them are the desire for breaking away from traditional ways of doing things, face the organizational and technical problems in decision-making process and measure up to the risks which are implicit in the process (Joshi, 1977: 40). Entrepreneurs can be divided into three broad categories i.e., Private Entrepreneur, Government Entrepreneur and Institutional Entrepreneur (K.C., 1989: 18–19).

Sustainable development aims at minimising waste and reducing exploitation of natural resources and energy, so that needs of the future generations are taken care of. Circular Economy (CE) is a new drift towards sustainability that aims at minimising waste and promoting material reuse, thereby creating a regenerative system. The construction industry is responsible for the extraction of raw materials and the generation of waste in large quantities, thereby making it an opportune sector for transition to a circular economy. On account of the complex nature of the built environment comprising various phases and associated actors, a proper framework or indexing for the circular economy is missing at present. This study aims to develop an integrated model of CE in the built environment which considers various construction stages and applicable strategies. An index for measuring the circularity potential in construction materials is also proposed, based on attributes developed from literature review and analysis of questionnaire survey. Simple Additive Weighting Method (SAWM), an elementary multi-criteria decision-making method is used for developing the index. It is anticipated that Circular Economy Potential Index (CEPI) would support decision-making in the initial stage of construction projects and help to compare the circularity of materials.
