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.
The monograph presents the analysis of the physical and mechanical properties of sunflower oil, technical means of post-harvest processing of crops and the results of pneumatic and pneumatic gravity devices studies. The analysis of sunflower seeds production in Ukraine, the technical equipment of the post-harvest sunflower seeds processing, theoretical studies of the separation process of air separated impurities, the methodical aspects of the experimental devices research, the results of laboratory and field research on experimental devices, practical application of the conducted research results and their economic efficiency evaluation are described.This monograph is aimed at scientists, teachers, students and other categories of readers related to the activities of the agro-industrial complex
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
