Abstract: The subject of the study is the system of relations related to ensuring the economic security of Russia as part of the Eurasian economy in the conditions of the current global crisis, and the choice of the main directions of its development in the presence of Western and Eurasian models of positioning in the world economy.The object of the study is the state of the world market in modern conditions in its dialectical dualism of the presence of Western and Eurasian models of positioning of national economies.
The authors consider in detail such aspects of the topic as the problem of the presence in the modern global economy of two main concepts as part of the development of the modern world market: financial and industrial. Particular attention is paid to which groups of countries are developing within the framework of these concepts, and Russia's position in relation to them is determined from the standpoint of ensuring its economic security.     The main conclusions of the study are the following:
- there are two main models in the modern market: the Western one, which is based on the priority development of the financial market; and the Eurasian one, which is based on the development of real production;
- Russia in recent decades has sought to develop according to the Western model, but has a high degree of adaptation to the Eurasian one, especially due to the development of extractive industries;
- the way out of the current crisis is likely to involve a shift in global emphasis from the financial concept of development to the production one.
In these conditions, it makes special sense for Russia to develop and implement a comprehensive program for closer integration into the Eurasian economy. It is this integration that will give economic security a qualitatively new level.
A special contribution of the authors is to identify the main directions of Russian economic and managerial activities to ensure the repositioning of the country's economy according to the Eurasian model after the end of the current crisis.
The novelty of the study lies in the statistical substantiation of the parameters of the difference between the Western and Eurasian models.

Abstract: The subject of the study is the system of relations arising in ensuring the environmental safety of modern Russia in the field of waste processing of solid industrial and household waste.
The object of the study is the regional economy of the Volgograd region, where there are significant opportunities for the creation and development of incineration facilities.
The authors consider in detail such aspects of the topic as: analysis of the development of the incineration business in the global economy; justification of the potential of the incineration business in modern Russia; analysis of the practice of creating waste disposal facilities in domestic conditions; justification of the construction of incineration plants in the Volgograd region.
Special attention is paid to the economic justification of the efficiency of incineration plants in the Volgograd region.

The main conclusions of the study are the following: waste disposal is currently a very promising area of business development, a powerful aspect of the growth of the regional economy of some subjects of the Russian Federation; international experience shows that a very powerful economic potential is already involved in this area, especially in the most developed countries of the global economy; the modern market offers a wide range of technical and managerialcommercial funds for the development of waste disposal enterprises; in many regions of Russia there is high business activity for the development of waste disposal enterprises, but this activity encounters environmental restrictions and inertia on the part of environmental organizations; creating conditions for the development of waste recycling facilities in the Volgograd region will have a high economic effect and will have a positive impact on the overall socio-economiceconomic development of the region.
A special contribution of the authors to the study of the topic is its actualization and attraction of rich world experience.
The novelty of the research lies in the adaptation of the research topic to the practical conditions of the Volgograd region and other regions of Russia.
