New approach for recycling spare parts, components and assemblies

Recycling and disposal are one of the most complicated topics in the lifecycle of a mechanism, especially in case of previous generations of machines that were designed without taking any care of post exploitation period. In the current work, the ‘feasibility points’ of recycling units, methods of recycling as well as pricing formation for recycling materials, reviewed and proposed by several world universities and scientific bureaus and applied by major world brands have been analysed. The general principles that should be rated as a basis when designing and creating new mechanisms, as well as the actions which we consider as a necessary supplement to the existing rules of the lifecycle of assemblies and which should be applied in practice, were introduced by authors in the ‘Management of parts and components for units and assemblies in mechanical engineering industry and its impact on the environment’. It was discovered that even modern assemblies, not to mention previous generations, are being designed without taking into consideration any possibilities of easy recycling the used materials. The number of components of mechanisms, which are being repaired as assemblies, is continuously increasing, while maintainability and repairability of separate parts is decreasing. Taking into account the state of the art in the field, the new approach for promoting the reusing natural resources and decreasing the harmful effects of obsolete components of mechanisms on the environment is proposed. Thus, using the fast-moving parts that in post operational period can be easily detailed by type of a material will ensure more efficient consumption of natural resources. Our research and developments significantly reduce the costs of recycling and these materials become competitive comparing to the new ones. Taking into account the state of the art in the field, the new approach for promoting the reusing natural resources and decreasing the harmful effects of obsolete components of mechanisms on the environment is proposed

Band structures for binding and holding of objects made from recycled metallic materials

ArticleThe aim of the present research is the investigation of the possibility and effectiveness of using the band structures made from recycled metallic materials for binding and holding of objects (in particular, tubular objects as pipelines or shells). The using of band elements and structures as such is a perspective way to increase the safety and bearing capacity of the pipelines and vessels. Nowadays during repair works the outer surfaces of the mentioned objects are braided by the steel tapes, i.e. the objects are strengthened by the binding. The mentioned steel bands are specially produced for binding purpose. From the other hand after stamping of smallsize details (like the elements of supply chains for different apparatus) the metallic waste in the shape of perforated metallic tapes are received and needs to be reused in compliance with the good practice in effective resource using and recycling. The band structures for binding and holding of tubular objects, produced from the perforated metallic tape by the longitudinal profiling, multilayer and spiral winding are presented. It is proposed to apply in industry the composite band structures made from perforated metallic materials and epoxy matrix for binding and holding of tubular objects as pipelines or shells, which allows simplifying and speeding up the repair works especially in the cases of the local damages

Spatial and Technological Diversification of the Russian Economy

The article explains the technological diversification of the Russian economy as the main precondition for sustaining the economic development and strengthening the internal economic space. The industrial-based approach applied for understanding the economic diversification prospective is criticized for its theoretical shortcomings, leading to the false conclusion of unfeasibility of the technological diversification of the Russian economy under the harsh conditions of the western sanctions and financial restrictions. The new theoretical insight, based on new notion of «spatial technological diversification» is presented to reveal substantial hidden capabilities for horizontal and vertical diversification in Russia. The new path for the breakthrough economic development should be based on specific «regional comparative advantage», identified for every region as a main frame for its specific vertical technological diversification while the horizontal diversification, embracing different regions with their different «regional comparative advantage» might be applicable for the Russian economy in general

Eurasian Civilization in the Context of the Great Silk Road Logistics

The significance of the Great Silk Road is interesting not only by its history, but by the knowledge, required for the better understanding of the current economic and political realities as well. The introduction of the new insights into the essence of the Eurasian trade route, its emergence and destruction studied under the projection on the contemporary processes, undermining the global supply chain represents the main idea of the given research. In the article, the Great Silk Road is represented in the logistics framework: generation of the freight flows, peculiarity of their material composition, the pathway trajectory architecture, creation of the necessary infrastructure. The significance of the spatial peculiarity, natural preconditions and advanced technologies for the freight generation, the international trade development and the Eurasian civilization emergence is emphasized. The paper reveals special logistic characteristics of silk as the initial chain in the ancient trade as well as the distinctive characteristics of transportation mode and freight. The political stability plays a significant role in the risk reduction for the freight turnover and for functioning of the international transportation system in general. The endogenous and exogenous reasons for the Great Silk Road breakdown are related with the increasing trade deficit between the East and West, the import substitution policy accepted by the European countries and increasing protectionism in their external trade relations. Exploring the Great Silk Road downfall, the author concludes about the contemporary global supply chain disruption causes, emphasizing the negative impact of the economic and political influence. The US-China trade war destroys the international trade. The COVID-19 pandemic tends the business localization. Ecological threats provide new requirements to the freight flows. The “pull strategy”, practiced by the logistic companies is steadily replacing by the “push strategy”. Moreover, China has been reducing investments into the trans-Eurasian project. That kind of instability could lead to a deep transformation of the international transportation systems as well as the system of the international relations in general. Russia should consider those new realities carefully when scheduling its international division of labour strategy

Globalization versus Localization: The New Management Paradigm of 21th Century

The 21th century challenges and the erosion of the global economic and business networks makes it urgent the rethinking of the main scientific research discourse in management. The article provides the overview of the scientific publications, dedicated to the globalization of the world economy and the main causes of the upcoming deglobalization. It is highlighting the impact of the strengthening trade and techno nationalism as well as the COVID-19 pandemic consequences on the world economy in general and the creation of global value chains in particular. It is also explains the imperative of economic and business processes localization by the degradation of the global environment and climate change. Some authors state that the new theoretical mainstream and a paradigm of management is needed to reflect the realities of the substantial transitions in the global economy

Technological Restructuring of Economies of the Former Soviet Union: from “Destruction” to “Creation”

Modern geo-economic and geopolitical processes create a need to rethink the integration interaction between the republics of the former USSR, now — sovereign countries. This is due not only to the rapidly increasing instability of the global financial system, the growth of trade and economic contradictions between countries, but also to the possibility of using the previous experience of inter-republican industrial-technological and intellectual cooperation to achieve the goals of economic development.Aim and tasks. The article’s main aim is to frame the technological and economic interaction between the former republics of the USSR in the new geo-economic and geopolitical conditions.Methods. The methods applied includes empirical and statistical analysis, the use of consistency, the principles of scientific discussion, dialectical methods of cognition, such as the unity of the historical and logical, the principles of induction and deduction, the principle of the linkage between qualitative and quantitative characteristics, the unity of analysis and synthesis.Results. The article highlights the features of the trajectory of the economic development of the former Soviet republics. The main problems associated with the transition to a “free market economy”, such as declining economies, population decrease, significant external debt, “Dutch disease” and deindustrialization of the economy, are identified.Conclusion. In conclusion the need to develop a new economic policy in the countries of the former USSR is argued from the standpoint of increased instability in the external economic environment and the need to strengthen their national economies, but also by the loss of economic independence and the accumulation of problems during the period of building a “market economy”. Significant efforts are required to restore the economy of the former republics of the USSR. The strategic direction is the reindustrialization of the economy, that is, the restoration of the lost economic potential on a new industrial and technological basis. For the successful implementation of the goal of strengthening economic sovereignty, it is of great importance to unite the scientific, intellectual and educational potential of the former republics of the USSR and create a common technological space. This will inevita bly lead to the formation o f a new system of international division of labor in the post-Soviet space, which is the main feature of a market economy

Ecological Challenges and the Modern Economic Development

Climate change and the other environmental problems have been threatening the business and economic sustainability in all over the world and undermine the human existence in general. The article examines various global challenges, stemming from the anthropogenic impact on the nature and assesses their economic consequences. Despite the international community endeavours to react on the environmental change in a number of agreements and actions, their positive effect is still low. The article states the limitation of the fiscal methods, applied for the climate change actions and underlines the lack of the holistic approach needed for overcoming the various types of the anthropogenic pressure on the nature. The proposition is made for classification of the environmental problems in terms of their impact on national economies. The effect of the environmental problems is more severe for the countries having the lower level in economic development, which means that overcoming the ecological problems could be successful when the less developed and falling behind countries have been catching up the more advanced nations. The technological restructurization of the national economies is represented as the main road for coping with the ecological problems. Russia represent a special case in within ecological problems, mostly determined by the substantial raw resources dependence of its economy, which reveals the necessity of technological restructurization of the national economy based on the drastically substitution of raw resources by the science ware and green production

Global Economy: Moving from a Standardized to a Non-Standardized Development Model

The world economy has entered a new phase of its development — the destruction of the technological system created after the WWII.   The purpose of the article is to argue that the destruction of the standardized economy is the main cause of the most acute problems of the world economy.   The common features of standardized production and economy of scale are investigated. The key role of dual use technologies in the development of a global system of standardized production and a special role of the Chinese economy in the development of the economy of scale, which the country played in the 21th century, are described. The author comes to the conclusion that the cyclical downturn of the world economy is caused mainly by the exposition of the techno-economic model of standardized production, which leads to the aggravation of international economic conflicts and contradictions such as trade wars, global supply chain disruption, disintegration and many others. The destruction of the standardized economy of scale is manifested in the increase in the production and transportation costs, the global inflation growth, the global supply chain disruption. In the study the author applies the methods of empirical research and theoretical cognition. Methodological novelty is presented in the argumentation of the global economic transition from a standardized economy of scale to a non-standardized economy of scope. The business localization, the new trend towards resource saving mode in production, the necessary diversification of industrial production consistent with the specifics of the given locality are just a few among others arguments that testify to this transformation. The article highlights preliminary features of economy of scope, based on the non-standardized technologies, such as heterogeneity, diversification of production, continues technological improvement, compliance with a specific regional comparative advantage in business clustering

Tools for building production and woodworking made from the perforated steel wastes

ArticleThe rising of efficiency of the building and construction production is an actual task. One of the possible ways to ensure higher efficiency is using innovative tools and facilities of small-scale mechanization, which increase productivity and enchase working condition. Most observable influence of such strategy is on concrete works, plastering and earthworks. Another important tendency in production engineering, building and construction production is recycling of the technological wastes, which sufficiently reduce cost of the products and improve ecology. The goal of the present paper is to offer new possibility for recycling of the technological wastes, i.e. perforated steel tapes achieved after stamping of fine parts, by producing from mentioned perforated tapes the building tools and facilities of small-scale mechanization. In particular, the technological wastes of the JSC ‘Ditton’ (Daugavpils, Latvia) – perforated steel tapes – received after stamping of the elements of driving chains for different apparatus were used in this research. The prototypes of the scrapers for the finishing building work, as well as cutting edges and circular coronas for the woodworking were elaborated and offered in this work. The results of approbation of elaborated prototypes of the tools are offered. It was proven, that proposed innovative tools could be used effectively in building production and woodworking
