Scarcity Of Resources

The reflections of linear and circular economy models, which are completely separated from each other in the ways of evaluating resources and wastes, also differ completely in the production and consumption processes. The linear economy, which consists of production and consumption mechanisms, converts resources into waste after using one time and is supported by planned obsolescence practices and causes economic and environmental damages. The scarcity of resources and the pressure of environmental pollution have led to an industrial transformation in which production and consumption forms redesigned in a way that does not create waste. Because of this transformation, the circular economy model emerged, and its application direction evolved to cradle-to-cradle practices. In this study, firstly, the linear economy model and planned obsolescence are discussed, and then circular economy and cradle-to-cradle applications are explained with examples.

The concept of sustainability is attracting great attention as societies become increasingly aware of the environmental consequences of their actions. One of the most critical challenges that humankind is facing is the scarcity of resources, which are expected to reach their limits in the foreseeable future. Associated with this, there is increasing waste generated as a consequence of rapid growth in the world population (particularly in urban areas) and a parallel rise in global income. To cope with these problems, a linear strategy has been applied to increase efficiency by reducing the use of materials and energy in order to lessen environmental impacts. However, this cradle to grave approach has proven inadequate, due to a lack of attention to several economic and social aspects. A paradigm shift is thus required to re-think and innovate processes (as early as in the design phase) in such a way that materials and energy are used more effectively within a closed-loop system. This strategy, known as the cradle to cradle approach, relies on the assumption that everything is a resource for something else since no waste is ever generated in nature. In line with the cradle to cradle approach, the bio-inspired circular economy concept aims at eco-effectiveness, rather than eco-efficiency. While the circular economy has neither a confirmed definition nor a standardized methodology, it nonetheless carries significant importance, since it “is restorative and regenerative by design and aims to keep products, components, and materials at their highest utility and value at all times, distinguishing between technical and biological cycles,” in accordance with the goals of the 2030 Agenda for Sustainable Development. Despite some controversial opinions that “circles are not spirals, and for growth to occur, spirals with ever-increasing radii are required,” the circular economy concept is taking a central role in the sustainable development debate and, for this reason, deserves attention. The aim of this paper is to shed light on this debate, pointing out the main features of the emerging circular paradigm along with sustainability transition theories and circularity evaluation tools.

The relevance of the research is environmental management is the basis for natural resources conservation, environmental protection and environmental safety. Meanwhile, it is important to use the best available technologies for neutralization and processing of production and consumption waste in addition to observance of the legal and environmental rules. Waste management of production and consumption is one of the main directions of the transition to a circular economy and the use of low-waste and non-waste production, which has recently been actively demonstrated by developed countries. The main aim of extrusive processing of meat waste is considered. Extrusive processing of waste - an effective solution of problems of rational environmental management as allows to make in addition secondary resources products, thereby realizing the principles of economy of the closed cycle; and considerably to reduce environmental pollution due to refusal of burning and waste disposal of livestock production and the meat-processing enterprises. Subject, tasks and methods of a research is processing of meat waste which call still biological waste and which are formed, generally in livestock production and at the meat-processing enterprises. One of perspective technologies of high-quality processing of waste is extrusive processing. Research results confirm that In Russia outdated neutralization and recycling of agro-industrial waste technologies lead to the loss of resources. Moreover they have a significant negative impact on the environment. This article deals with the method of extrusion recycling of meat waste. Extrusion recycling of waste is an effective solution to the environmental management problems, as additionally it allows to produce products from secondary resources, thereby the principles of closed-cycle economy are implemented, and significantly reduce environmental pollution by eliminating the burning and disposal of animal waste and meat processing plants. Thus, use of extrusive technologies will allow not only to make waste products, to get additional profit, but also to prevent pollution of air, water and land resources harmful substances, providing thereby rational environmental management, and will form a basis of transition to circular economy which formation is impossible without environmental safety.

Coal Mining Industry

The circular economy is the economic model that has been applied for a long time in theworld. This model is applied at all three levels: micro (enterprise-level), intermediate (industry level,industrial zone level), and macro-level (local level, regional level, or national level). Vietnamese CoalMining Industry has been having important contributions to the socio-economic development ofVietnam. However, this industry also causes lots of issues about environmental pollution. In the contextof resource depletion, environmental pollution and the cost of exploiting and processing increases withthe deep exploiting process; the tastes of utilizing resources, minimizing environmental pollution, andcreating more value-added for this industry are inevitable requirements. Because of the tasks, applyingthe circular economy model into this industry (both intermediate and micro-level) is the urgent solutionfor the sustainable development of the Vietnamese Coal Mining Industry. The paper uses a combinationof research methods such as theoretical research, case study research, statistical data analysis, etc., topropose the circular economy model for the Vietnamese Coal Mining Industry and some solutions todeploy this model into the industry's operations towards sustainable development.

Abstract The circular economy model has recently gained a lot of attention worldwide from scientists, business people and authorities. The importance of the transition towards a more circular economy has also been noticed in the European Union. The new regulations provide the enabling framework for the circular economy to flourish. At the same time, although there is no standardized approach to creating a circular economy, while defining appropriate policies, care must be taken that they are suitable for particular industries. The limits of the present linear economy model (take-make-waste) are extremely apparent when examining the textile and clothing industry. The transition to a circular economy requires significant changes in both production and consumption models. This article uses a literature review and industry examples to identify and evaluate challenges faced by the clothing and textile industry in adapting to the circular economy model.

The article discusses the basic principles of the implementation of the transition from a linear economy to a circular economy model. The article summarizes the existing problems that require solutions to create new jobs, increase economic growth, and create a balance between the economy, environment and population. The authors present examples of building a circular economy model in foreign countries. The importance of the tasks of implementing and promoting the circular economy was revealed, thanks to the involvement of all participants in the society in this process and the motivation for companies and investors. Effective tools for moving society towards a resource-efficient closed-cycle economy, increasing energy efficiency, energy conservation and reducing the energy intensity of the gross domestic product, due to the entry into a competitive level of renewable energy sources are investigated. The introduction of digital technologies and artificial intelligence in automated accounting of resource consumption, as well as the improvement of accounting rules will create opportunities for the end user to manage resource consumption taking into account the principles of a circular economy. The authors' study emphasizes that circular economy products and services should minimize resource use and promote reuse, recovery and recycling of materials in the future, leveraging existing product policy instruments, further support for the repair sector, improved design for reuse, and high-quality packaging recycling. The authors in the article propose to legislate the subsidizing of enterprises participating in the circular chain and subsidizing innovative developments in the field of the circular economy in the Russian Federation.
