Searching for solutions, which restrict consumption of resources and exhausts of green-house gases, is essential for providing stable economic growth. Industrial symbiosis turned to be a strong ally in reaching ecological, economic and social goals, which is proved by a rising number of publications on the subject. A higher proliferation of industrial symbiosis was observed in Europe and Asia, especially in China, which is connected with state policy realization. In manufacturing sector contracts of industrial symbiosis were signed not only because of the increasing amount of waste, but due to the possibility to integrate waste and by-products in production cycle. It affected mainly chemical, cement, pulp and paper and steel-making industry and oil-refining plants. In case wastes of other industries are used, not only positive effect for the company is feasible. Wastes are often of lower quality than initial materials, which they substitute for. The article shows how companies can control the waste quality by integrating waste suppliers in operative processes of the company - buyer. The author substantiated that control of the waste quality is the key possibility for industrial symbiosis, especially when companies would like to raise the efficiency of their work in the field.

Aim. The presented study aims to analyze problems associated with the possibility of implementation of platform solutions by companies in the aviation industry, and to formulate recommendations for the implementation of such solutions.Tasks. The authors provide an overview of scientific literature on the topic; describe the main principles of selecting companies and sources of information for the study; present the results of the study in a structured manner; formulate recommendations for the development of companies in Russian aviation industry.Methods. This study is based on the analysis of the activities of Russian and international innovative companies in the aviation industry.Results. Analysis of company activities in the aviation industry highlights the regional aspect in the development of digital infrastructure and technologies, which directly impacts the digital transformation of the industry.Conclusions. The authors provide recommendations for using platform solutions in aviation industry companies to allow Russian players to achieve leading positions in the global market. The obtained findings can also be used by companies in other sectors of the economy to adjust their business models, as well as for similar studies.

Economic activity in the Arctic is playing an increasingly important role in the globalizing economy, given that such an economy is largely based on natural resources (oil, gas and minerals) as well as the long-distance transport of these resources and related goods. The Arctic seems to be one of the last opportunities to exploit vast resources, which, ironically, made it possible by the negative effects of this very exploitation in the form of global warming and the subsequent retreat of the ice cover of the circumpolar North. Thus, the Arctic has already become and will continue to be part of economic globalization. The article gives an analysis of the dynamics of the «Polar Index of the Barents region. Companies». The need to include the main elements of industrial safety in the sustainable development of the Arctic has been justified, as well as the establishment of industrial symbiotic cooperation rating based on it. Industrial symbiosis is an economically efficient and environmentally friendly solution for industry that reduces energy consumption and primary material consumption by deriving value from waste, byproducts and heat losses.
