The issues of the environmentally friendly business development in Russia are considered in the paper. The authors research the concept of green production and market, management tools for corporate environmental responsibility. The paper examines the environmental innovations as changes in the socio-economic development of the society, which, together with a positive effect, improve the state of the environment or significantly reduce the negative impact on it. In the conclusion, the authors state that the greening of the enterprise’s relations with consumers implies, on the one hand, encouraging the supply of environmental goods and services, and on the other, creating a consumers’ good taste - economic needs and interests oriented to high eco standards. In the paper, the necessity of the green business guidelines implementation in Russia is justified. It helps to form and improve the entrepreneurial culture and a responsible attitude towards society and nature, as well as to promote principles of green economy.

Geothermal heat supply occupies the second place among the renewable energy sources around the world in installed capacity (70.3 GW) and in the amount of generated thermal energy (163 (TW h)/year). It is outperformed only by solar heat supply (480 GW and 395 (TW h)/year). The use of geothermal heat involves the need to drill wells and fulfill special requirements for development of geothermal fields and construction of heat-supply systems. There are deep (more than 400-m deep) and shallow geothermal heat-supply systems (GHSSs). More than 66 geothermal fields have been explored in 11 regions of Russia, and the operating reserves total more than 300 000 m3/day. The installed capacity of Russian GHSSs totals 310 MW. Differences between open- and closed-loop GHSSs are pointed out. For open-loop GHSSs, their typical process circuit arrangements implemented in Krasnodar krai and in the cities of Kizlyar and Makhachkala are presented. The GHSS process circuits with the use of heat pumps (HPs) for recovering the heat of spent geothermal water and systems operating in combination with solar units are considered. Systems that use highly mineralized geothermal heat carriers from different geological horizons with heating of sweet water, as well as GHSSs with pumpless circulation of heat carrier, are described. The article gives examples of GHSSs equipped with geothermal circulation systems (GCSs) implemented in the Khankala geothermal field in the city of Grozny, including the double GCS with the design capacity equal to 8.7 MW and the GCS in the Medvedevka settlement in the Dzhankoi raion of Crimea, a distinctive feature of which is that it uses wellhead methane for generating electricity and for additionally heating the heat carrier in the peaking modes of operation. In constructing open- and closed-loop surface GHSSs, heat pumps are commonly used. In the first case, the heat of underground or surface water bodies is used, while horizontal or vertical heat exchangers are applied in the second case. Examples of geothermal heat-supply systems are given: the surface GHSS in the city of Makhachkala, in which ground heat exchangers in combination with solar units are used, and the GHSS in the city of Krasnodar, which serves for heating an administrative building and for cooling it in summer. The key scientific–technical problems requiring further investigations and development for constructing efficient and competitive geothermal heat-supply systems in different regions of the country are formulated.

Abstract Reclamation of disturbed land is a relevant issue, as each year, more and more land becomes unsuitable for economic use due to human activity, which alters the terrain and creates anthropogenic landscape, ultimately disturbing a variety of lands. Not only is disturbed land no longer suitable for economic use, but also is subject to intensive water and wind erosion, the products of which pollute the environment. The area susceptible to the negative effects of mining is about ten times the size of disturbed area. Reclamation of disturbed land is of special relevance in Russia, as the country is a leading producer and exporter of hydrocarbons, resulting in a worrisome lead in terms of pollution with oil and petroleum products, pesticides and heavy metals, as well as in the scale of soil-disrupting activities such as construction, amelioration, logging, surveying, testing, exploration, and operation of various facilities. This paper discusses the current state of the art of disturbed land reclamation in Russia. The authors analyzed statistics from Rosreestr, Rosselkhoznadzor, and Rosprirodnadzor.

The urgency of the issue is reasoned by the necessity to develop environmentally friendly technologies and engineering tools for cleaning emerged mineral oil from insoluble impurities in order to reuse them in the nodes and auto-tractor equipment systems. Hydrocyclone is one of the simplest and most effective means of cleaning waste oil. In order to determine the possibility of hydrocyclone usage in technological lines for purifying oils, it is necessary to establish the influence of its geometrical parameters on the purification quality of such high-viscosity liquid as emerged mineral oils. The purpose of the article is to study theoretically the cylindro-conical hydrocyclone geometrical parameters influence on the purification degree of emerged high-viscosity mineral oils from insoluble and wear debris. The leading approach to the study of this problem is the consideration of the behavior of a non-soluble particle in an oil stream under the influence of forces acting on it, which allows identifying the geometric and regime parameters of a cylindro-conical hydrocyclon. These parameters have the greatest influence on the oil purification degree. The article presents a theoretical justification for the geometrical parameters influence of a cylindrical-conical hydrocyclone on the emerged oil purification degree, a separation criterion, which allows not only determining the optimal size of a hydrocyclone, but also conducting a comparative assessment of hydrocyclones with different geometric parameters by oil purification efficiency from insolubles. Theoretical researches are aimed at determining the cylindro-conical hydrocyclone geometric parameters, depending on the pollution intensity of the emerged mineral oil and the desired degree of its purification from insolubles.

The article reveals the essence of the concept of “responsible person” and the problem of its пenesis. Different theoretical and methodological approaches to its definition are shown. The phenomenon of social responsibility is considered as the basis of productive social creativity. The author analyzes the main trends and the nature of the process of formation of social responsibility of the individual in modern conditions. Particular attention is paid to increasing the role of personal responsibility in times of social instability and uncertainty. The accumulated experience of scientific understanding of the concept of «social responsibility» is revealed. Specific features of social responsibility and its interpretation in the works of F.Bastia, I. A. Ilyin, P. A. Kropotkin, I. I. Lapshin, N. O. Lossky, V. S. Solovyov, N. F. Fedorov, and others.
