Nazar Tkach, National University of Life and Environmental Sciences of Ukraine, Tetiana Mirzoieva

Abstract: The article presents a study on the justification of the economic feasibility of processing cereals into biogas. Аt the first stage the sown areas and productivity of separate agricultural crops in the investigated enterprises of Brovarsky district, Kyiv region were analyzed. The tendency to increase the yield of agricultural crops in the studied enterprises was revealed. This was seen as evidence that they could potentially be fully self-sufficient in raw materials for the production of gaseous biofuels. At the second stage of the study, the potential volume of the raw material base for biogas production in the studied enterprises was calculated, potential volume of biogas production and economically feasible volume of biogas production for each enterprise. It is proposed to use part of the grown grain for bioenergy production, and this part should be 10-15% of the gross harvest of grain enterprises in order to prevent the food crisis in the country. At the third stage of the study to determine the economic efficiency of biogas production from wheat and corn, investment costs were calculated, necessary for the implementation of the project to install a biogas plant in the studied enterprises. The authors calculated the investment costs required to implement the project of installing a biogas plant at the studied enterprises. The authors also analyzed the costs of each company for future projects. Finally, the economic efficiency of the proposed project for biogas production in the studied enterprises of Brovary district, Kyiv region is calculated, the economic efficiency of the project in the long run is analyzed with the use of discounted indicators of economic efficiency with a life cycle of 5 years. It was found that the implementation of projects for biogas production may be accompanied by high efficiency, all enterprises will receive profits from the implementation of investment projects for the production of biogas and biofertilizers with the subsequent sale of biogas and the use of biofertilizers for their own needs.
