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.

The Impact

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).

The Impact

Numerous studies demonstrate that the goals of economic growth frequently take precedence over addressing social problems and problems of environmental degradation. The manifestations of this imbalance differ from country to country depending on the stage of development of the productive forces, and institutional framework that ensures the creation and adoption of new practices and approaches to exploitation of natural resources. This problem is entirely inherent into the economies of resource regions. The paper aims to examine the impact of the extraction of raw materials demanded by the national economy on the problems and prospects of the long-term sustainable development of northern Russian localities. Methodologically, the research rests on the theory of inclusive development and evolutionary economic geography. The comparative analysis of the formation of local budgets and dynamics of the Okrug in Russia reveals that the degree of their financial sufficiency depends insignificantly on the scales and dynamics of raw material production. The legislation on assigning revenues to local budgets takes into account the specifics of the northern oiland gas-producing territories rather poorly. The financial capabilities of local communities do not allow handling existing ecological problems. The growth in hydrocarbon production in current institutional conditions does not guarantee sustainable long-term development for such territories. Addressing environmental issues requires instituting serious changes at federal and regional levels, including making the alterations to the articles of the Tax Code of the Russian Federation. It is also crucially important to give financial incentives to introduce new technologies, provide research grants, lower labour taxes, and raise taxes on the use of natural resources.

Mine tailings are waste materials that resulted from the extraction and processing of raw materials to form mineral products. These dusty particles present negative environmental effects after being deposited in different types of dumping areas. Based on the circular economy concepts and the presently pushing need of identifying wastes as a potential replacement for natural resources, this chapter aims to present the physical (density, microstructure) and mechanical (compressive strength, flexural strength) characteristics of different types of geopolymers which use mine tailings as precursors or blended systems (mixes of different raw materials). The main reasons of approaching this topic are the need to decrease the consumption of natural resources, reduce environmental pollution and create an economic system aimed to capitalize the mining wastes. Accordingly, this chapter includes information regarding the availability of this waste and its potential utilization as a raw material in civil engineering applications. Therefore, reports of specific agencies and multiple research studies which approach tailing based geopolymers or blended systems have been summarized.

The article overviews the problem of slowing down the rates of natural non-renewable sources depletion in the process of resources development. The goal of the presented research is to justify the implementation of the most appropriate method of carrying out a complete resource development process by incorporating the mining and raw material extraction facilities available in the country. The study provides scientific evidence of a large-scale harmful impact caused by the raw materials development to all the elements of the biosphere and their interdependence. The presented research also demonstrates that solving the problem of resource-conservation is a first-hand priority due to the fact that there is in a close interconnection between the levels of environmental pollution and the levels of natural resources extraction. The solution to the problem of natural resources conservation is based on the concept of implementing environmentally clean technology (ECT); this technology gives an opportunity for developing a concept of the best available technology (BAT) and the concept of a closed-loop supply, the latter of which has become widely-used as a form of circular economy. The authors of the article have also suggested a systematic range of techniques aimed at extracting following resources in full capacity: commercial resources, non¬commercial resources, overburden rocks and man-made mineral formations. The authors of the article suggest the necessity for enlarging the scope of available mineral resources by ensuring governmental support and developing small deposits, first and foremost focusing on the territories with a developed infrastructure and which had previously been developed. The ideas presented in the article express and support the necessity for prospective implementation of the mining factories waste products as a reserve for mineral and raw materials resources; as well as the necessity for increasing their production rates from the circular economy perspective. Some measures which would help to accelerate this process are: improving the legislative system, developing mechanisms for economic incentive and providing various forms of state-business co¬operation.

This article summarizes the arguments within the scientific discussion on the issue of using mining machines and their life cycle. The main goal of the article is to investigate the impact of a combination of mobile and stationary mining machines and their optimal distribution in the mining process to increase the efficiency of mining and processing of raw materials. The following methods of research were focused on the use of technical indicators for the valuation efficiency of the mining process: a simulation method was used for the distribution of mining machines, comparison analysis was used for the real and past state of mining machines, and a decision tree was used as managerial instrument for optimal alternatives of mining machines. The research empirically confirms and theoretically proves that optimal distribution of mining machines and machine parks is very important for mining companies. The benefit of this research for the mining company was the new location of the machines and the combination of stationary production lines and mobile equipment. The optimal layout of the machines reduced the number of conveyor belts and improved the transfer of limestone processing to mobile devices, saving time, which was reflected in transport costs. The results can be useful for other mining companies seeking to create an optimal machine park.

The Impact

China’s wood industry is vulnerable to the COVID-19 pandemic since wood raw materials and sales of products are dependent on the international market. This study seeks to explore the speed of log price recovery under different control measures, and to perhaps find a better way to respond to the pandemic. With the daily data, we utilized the time-varying parameter autoregressive (TVP-VAR) model, which can incorporate structural changes in emergencies into the model through time-varying parameters, to estimate the dynamic impact of the pandemic on log prices at different time points. We found that the impact of the pandemic on oil prices and Renminbi exchange rate is synchronized with the severity of the pandemic, and the ascending in the exchange rate would lead to an increase in log prices, while oil prices would not. Moreover, the impulse response in June converged faster than in February 2020. Thus, partial quarantine is effective. However, the pandemic’s impact on log prices is not consistent with changes of the pandemic. After the pandemic eased in June 2020, the impact of the pandemic on log prices remained increasing. This means that the COVID-19 pandemic has long-term influences on the wood industry, and the work resumption was not smooth, thus the imbalance between supply and demand should be resolved as soon as possible. Therefore, it is necessary to promote the development of the domestic wood market and realize a “dual circulation” strategy as the pandemic becomes a “new normal”.

Батыс Қазақстан облысындағы кәсіпорындардың эволюциясы экономикалық дамудың жалпы циклдік сипатына байланысты да, әр түрлі сыртқы және ішкі факторлардың осы салаға әсер етуінен, сондай-ақ даму процесінде сөзсіз ауытқулар салдарынан ауытқуларға ұшырайды. Батыс Қазақстан облысының аймақтық агроөнеркәсіптік кешенін тұрақты дамытудың басымдықтары талдау арқылы анықталуы керек. Зерттеудің мақсаты - Батыс Қазақстан облысының агроөнеркәсіптік кешенінің тиімді және тұрақты дамуын зерттеу болып табылады. Бұл тақырыпты зерттеу кезінде статистикалық-экономикалық әдіс, талдау және синтез қолданылды. Ауылшаруашылық кешенінің жеке аймақ ретінде тұрақты дамуы да, жалпы елдің де дамуы ауылшаруашылық кешенінің тұрақты қалыптасуынсыз мүмкін емес, себебі оның түпкі өнімі қайта өңдеу өнеркәсібі болып табылады, ал оның мақсаты - талаптарына сай халықты сапалы өніммен қамтамасыз ету. Талдау көрсеткендей, ауылшаруашылық өндірісінің қазіргі жағдайы, қолайсыз факторлардың әсерінің күшеюімен сипатталады, ең алдымен табиғи факторлардың өндірісінде, жалпы өсімдік шаруашылығы өнімінің жылдық айырмашылықтарын тудырады, және өз кезегінде мал шаруашылығындағы ауытқуларға әкеледі, сонымен қатар оның әсері өңдеуші салаларда сезіледі, ал бұл өнеркәсіптің шикізаты болып табылады. Зертеу барысында 2015 жылдан бастап Батыс Қазақстан облысының аумағында ауыл шаруашылығы өнімдері өндірісінің күрт төмендегені анықталды, бұл жалпы, сондай-ақ өсімдік шаруашылығы мен мал шаруашылығы салалары бойынша да өндіріс тұрақтылығының төмендеуіне әкелді, және ол бүгінгі күнге дейін жалғасуда. Агроөнеркәсіптік кешеннің шикізат саласындағы өндіріс тұрақтылығының төмендеуі қайта өңдеу өнеркәсібі өнімдерін өндіруде ауытқулардың артуына әкеліп соқтырды, бұның нәтижесінде халыққа азық-түлік өнімдерін ұсынуда тұрақсыздық пайда болды. Батыс Қазақстан облысының АӨК-ін оның салаларының өнімділігі мен кірістілігін арттыруға бағытталған одан әрі дамыту өндірісті жаңғыртуды және қайта жарақтандыруды, оның инфрақұрылымын дамытуды және салалық кластерлерді қалыптастыруды талап етеді.

The evolution of enterprise in the West Kazakhstan region is subject to fluctuations due to both the general cyclical nature of economic development and the impact of various external and internal factors on this industry, as also fluctuations unavoidable in the evolution process. The priorities for sustainable evolution of the regional agro-industrial complex of the West Kazakhstan region should be identified through analysis. The goal of the research is to study the effective and sustainable development of the agro-industrial complex of the West Kazakhstan region. Through studies this topic, the statistical-economic method, analysis and synthesis were used. Sustainable development of the agro-industrial complex of both a particular region and the country as a whole is impossible without the stable functioning of its core - agriculture, the final product of which is used by the processing industry, whose goal is to provide the population with high-quality products in volumes that meet their requirements. Current state of agricultural production, as the analysis shows, is characterized by an increase in the influence of unfavorable factors on production, first of all natural ones, which cause annual differences in the production of gross crop production, which, in turn, convey fluctuations to the livestock industry and, as a result, affects the processing industries. it is the raw material of the industry. In the course of the study, it was found that, since 2015, in the territory of the West Kazakhstan region, there has been a sharp decline in agricultural production, which led to a decrease in the stability of production in general, and in the fields of crop and livestock production, which continues to the present. A decrease in the sustainability of production in the raw materials sector of the agro-industrial complex entailed an increase in fluctuations in the production of products of the processing industry, which ultimately resulted in the emergence of an instability in the supply of food to the population. Further development of the agro-industrial complex of the West Kazakhstan region, aimed at increasing the productivity and profitability of its industries, requires the modernization and re-equipment of production, the development of its infrastructure and the formation of industry clusters.

The key factor behind raw mix design in the cement factory is the appropriate production planning, resulting in high-quality raw material. Quarry managers usually come up with uncertainty-related raw materials due to variations in chemical composition. These uncertainties required efficient planning in terms of useful insight into this problem. This research provides a detailed explanation of scenario analysis of raw materials used in cement manufacturing using Monte Carlo simulation (MCS) and indices. Scenario analysis is used to predict the possibility of best, worst and most likely cases of raw material’s quality. Whereas, Monte Carlo simulation is used to evaluate the inherent uncertainty associated with chemical composition values in order to analyze the impact of truly unpredictable scenarios. The predictive results help in decisions related to production planning, raw mix design optimization and increasing the probability of designing the best plan.

This article examines the transformation of the labor market under the influence of informatization of society. It is noted that in the conditions of globalization and informatization of the nowadays a post-industrial society has been formed, in which information is a determining factor of production. New opportunities and challenges of the labor market in the conditions of information society development are analyzed. The informatization of society changes the conditions, nature and forms of work. Extensive digitalization, the use of cloud technologies and artificial intelligence systems are displacing traditional forms of employment towards teleworking, which makes workers more mobile and able to optimize working hours. It is established that the spread of technology increases the efficiency of the recruitment and searching job processes. Informatization of society contributes to the creation of a digital labor market, which forms the demand and supply of information and computer technology workers. In the context of informatization of society, the labor market is characterized by an imbalance between supply and demand of labor due to structural changes in the economy. Among the challenges of the labor market are rising unemployment in the raw materials industries, robotics and automation of routine manual labor. The digitalization of the economy leads to the need to adjust government regulation of business and provide social guarantees for employees. It is noted that the informatization of society provides more benefits to the labor market than obstacles. Solving the problems it raises, promotes progress and economic development.
