The paper represents the analysis, which has helped to establish the usage of gas hydrate technologies in the methane conversion. This gas could be obtained in different ways. Possibilities and sources for the gas obtaining have been demonstrated. Use of other environmentally friendly sources to support operation in such systems in terms of joint energy complex has been considered. The necessary kinetic connections to provide operational sustainability of all the constituents have been given. The approach helps evaluate quantitatively the priority of its physicochemical transformations to obtain gas hydrates artificially. It is possible to transport methane at considerable distances when it is solidified. Actually, in this case there is no necessity to build costly compressor stations and pipelines for its transportation to consumers. The approach is extremely important for mining regions as it helps prolong the operating period and working out of the abandoned and off-balance coal reserves. In this case, it is proposed to apply special gasification technologies tending to maximum methane recovery. The proposed solutions give the possibility to define the trends of our further research. They will be highlighted in the following authors’ studies.

This paper focuses on the visualization of eco problems and the latest green technologies, including energy-saving. Today, there are four color-graphic means in advertising: photography, graphics (drawing or computer graphics), font compositions, and often a combination of these. Our study considers the imagery and stylistics of eco poster as a type of public advertising, and ascertains that in the subject of energy-saving a light bulb as the visual stereotype prevails. The paper indicates the importance of system design thinking, the use of creative approaches in the educational process of designers (metaphor, metonymy, hyperbole, association, allegory also) in creating social appeals for a wide audience – from young children to the older generation. Moreover, it emphasized the social value of design, and the aesthetic, moral as well as communicative aspects of visual information of environmental orientation within the context of this study.

The paper presents the comparative analysis of the amount of waste generated in Ukraine and European countries (except for radioactive waste) based on the official EU and Ukrainian statistical data. The data on waste generation are compiled according to the following classification: by economic activity and household, waste category, grades of hazard, and regions. In Ukraine, 352.3 million tons of waste was generated in 2018. By 2018, almost 13 billion tons of waste had been accumulated at the managed dumpsites, including about 12 million tons of hazardous and over 200 million tons of household waste. In the European Union, 2.6 billion tons of waste was generated in 2018. Over 70% of it was generated by 10 countries: Germany, France, England, Poland, Romania, Italy, Sweden, the Netherlands, Spain and Finland. By economic activity, the largest amounts of waste in Ukraine are generated by the mineral extraction and processing industry, the smallest – from water treatment and construction. In the EU countries, these values are somewhat different. For example, in Germany and France, the largest amounts of waste are generated from construction and manufacturing, the smallest – from agriculture, forestry and fishery. By waste category, the waste generated both in the EU countries and in Ukraine is mineral and solid waste. In Ukraine, the largest amounts of waste are produced and accumulated in the Dnipropetrovsk, Donetsk and Zaporizhzhia regions which accommodate large enterprises for extraction and mineral processing of iron and manganese ores, titanium-zirconium placers, coal, dolomite, and metallurgical limestone, as well as metallurgical and ferroalloy plants.

The strategic documents of the state provide for inclusive and green growth aimed at the inclusion of society in the development of the state. It causes the need to highlight the main components of growth and guidelines for their calculation. The international community moved away from using the Gross Domestic Product (GDP) as a measure of economic development, and started measuring growth by calculating the Inclusive Development Index. The study conducted in the article is concentrated on the main directions of the international community development, which focus on assessment of the mineral resource management as one of the levers of increasing the production efficiency and taxes distribution. This article suggests to improve the rent payments for the minerals extraction through a correction factor, since the Tax Code of Ukraine does not take into account the multifunctionality of the territory where these resources are mined. The coefficient is estimated to vary from 1.25 to 2.0, depending on the polyfunctional characteristics of the mining area. This approach will improve existing methodological recommendations and include such an important area as inclusive green growth in the calculations, as not only the economic indicators of economic activity, but also the environmental feasibility of using the territory where it is carried out will be taken into account.

A person is in close contact with the natural environment throughout his life. In the interaction of nature and man, an important role is played by the preservation of ecological balance in the conditions of continuously growing needs of society. Environmental culture has a beneficial effect on the degree of development of the level of legal and environmental awareness in the society, as well as compliance by the members of the society with the requirements of environmental protection legislation. In the conditions of the rule of law, there is a great need for professional lawyers who are able to assist in the environmental and legal education of a person throughout his life. In order to raise the level of environmental and legal culture of the society, in our opinion, a special role should be assigned to professional lawyers, for whom this should be part of their professional activities. Within the framework of this research, we have proposed and implemented a case methodology on the subject of environmental law for law students.

The work is devoted to the analysis of the current state and prospects of modernization of the fuel and energy complex and investments in renewable energy in order to achieve the Sustainable Development Goals in Ukraine, adaptation of an economic and mathematical model adequate to this process, allowing for rational distribution of investments, which in Ukraine plans to attract to development of the energy system and renewable energy as part of the implementation of the strategy “Vectors of Economic Development 2030”, the collection of potential sources of funds for the development and construction of thermal power plants using alternative fuels on the basis of existing heat supply enterprises in Ukraine. In the article it is recommended to use the add-in “Search for a solution” MS Excel for performing calculations according to the proposed deterministic model of a partially integer linear programming problem with boolean variables. As a result of the implementation of the proposed approach, moderate protection of the main producers (network operators) – heat supply utilities will be provided and market conditions for independent producers will be created, the operator will be encouraged to increase the efficiency of its own production.

The chemical homeostasis of humans has changed due to global and local anthropogenic impacts on biogeochemical cycles. Their degree is mediated by natural geochemical character of local environments. The elemental composition of human hair and quantitative relation between elements is summary characteristic of biogeochemical environmental conditions. To determine the biogeochemical situation 78 inhabitants from different geographic regions across the Crimean peninsula, cities and rural areas were investigated through the analysis of 28 elements by neutron activation analysis and determination of mercury by atomic absorption spectroscopy. High variety of elemental composition in inhabitants’ hair on different types of territories in the Crimean peninsula was revealed. Comparison with different territories of Russian Federation and Belarus shows both common and specific features. On most part of Russian and the Crimean territories a deficiency of essential elements (Zn, Cu) in human hair is characteristic. At the same time there are significant differences in content of some essential elements (Ca, Fe) and other ones (Th, Ce, Au, U, Ag, Cs) even in the limited Crimean territory. It requires further investigation of factors, which determine the revealed variability.

The work presents the results of quantitative assessment of heavy metals (HM) content in bottom sediments of the coastal zone near the Karadag nature Reserve. The data were obtained as a result of field studies in 2016-2018. Estimated СС and Cо coefficients and Zc were calculated. It was shown that arsenic concentration limits were exceeded everywhere in the samples. The nickel, lead, copper and zinc limits were found to have been exceeded in some locations. Ecological and geochemical assessment of water and bottom sediments quality in the section of Karadag water area has been made.
