Manufacturing and the further utilization of biogas is an efficient way of complementing or replacing primary energy resources. Ukraine has followed the global tendency to substitute fossil energy sources with renewable ones, which particularly includes biogas. Considering the experience of European countries, as well as the potential and needs of Ukraine, the necessity of biogas plant building implies three main factors: obtaining the energy sources, selling agricultural products and by-products of biogas production, and managing the environmental issues surrounding biogas generation. The growth dynamics of biogas plants and their productivity were analyzed for the period of 2012–2019. In doing so, the capacity and potential capabilities of biogas production in Ukraine by means of biological waste and agricultural raw materials were assessed. The article focuses on the importance of resolving the issues of sanitary and technogenic protection in biogas plant building and biogas manufacturing. It also points out the reasons that prevent Ukraine from going forward with biogas projects, as well as the main factors that affect biogas plant viability and efficiency. Based on the statistical data of previous years and regression analysis, the authors calculated the production output and biogas transformation. Herein, the trend model and Excel software were applied.

One of the most relevant scientific studies of social economic policy of countries around the world is the development of bio-oriented economy. Many countries are creating new models of innovative development, one of which is bioeconomy. The purpose of the study is to determine the priorities of implementation bioeconomics model of innovative development in Ukraine. The main task of the study is to outline the possibilities use of new innovative methods of production on the basis of development of a bio-oriented economy. General scientific and special research methods: method of theoretical generalization for the formation of their own approach to understanding of the new paradigm of economic development on a bioeconomics basis; morphological analysis to clarify the conceptual and categorical apparatus regarding the researched problem; method of system analysis for the study of scientific and legal principles bioeconomy development. The article describes a new direction of economic development at which is reused and recycled, conditions are created for multiple, cyclical use of resources that creates a basis for the formation of the bioeconomy. The necessity of using modern knowledge in economics is considered human activities to restore the environment on the basis of the latest production technologies and biological resources. Characterized State bioeconomics strategies of the EU and Ukraine for development bioeconomy. One should notice that the bioeconomy is considered a key basis of modern innovative areas of economic development. It is based on extensive use of biotechnology and the use of biological renewable resources for production and energy production. Attention is drawn to the fact that the priority areas of the bioeconomy are creating preconditions for the economical use of natural resources, minimization of environmental risks and integration of biotechnological knowledge in different sectors of the economy and the establishment of economic ties between industries that were not previously the subject of the study. It is concluded that the role of the core of the bioeconomy is performed by the rural economy, as it is the main raw material base. Bioeconomy based on biomass and biotechnology where the main components are renewable biomass sources, in particular of agricultural origin.

The state and prospects of small hydropower development in the context of rationalization of the use of available natural resource potential of Ukraine were considered. It was established that due to insignificant specific weight in the general energy balance, small hydropower cannot significantly affect the structure of energy supply of the country. Attention was drawn to the fact that the adopted State Target Economic Program for Energy Efficiency and the Development of Energy Saving for Renewable Energy Sources and Alternative Fuels for 2010-2020 will promote the use of the potential of small rivers and the development of hydropower. It was noted that the conducted calculations for the future with the help of correlation analysis of installed capacities and production of electricity by small hydropower objects showed that in 2020, at the current rate of development of small hydropower, the planned indicators will not be achieved. The legal principles of functioning of the market of electric energy and formation of relations connected with the development of small hydropower, which are regulated by the Laws of Ukraine and other legislative acts in the field of fuel and energy complex were described.

The article considers the state and prospects of bioenergetics development in the context of rationalization of the use of available natural resource potential of Ukraine. It is determined that one of the most perspective renewable energy sources is biomass, the main component of which is by-product of plant growing. It is noted that the use of by-products of crop production for receiving heat energy is a rational way to utilize their surpluses that are not used for other purposes of agriculture. The existing resource potential of this agricultural biomass and source of its obtainment were characterized. An estimation of the potential of this type of biomass up to 2025, which can be used for thermal power engineering was made. It was noted that the effective use of biomass potential of agricultural enterprises is possible in case of creation of the appropriate mechanism, a set of management decisions aimed at solving the energy issue. The structure of the formation of the economic model of the influence of factors on the state of the use of by-products of crop production in thermal power engineering was proposed.
