Renewable energy sources in Ukraine account for only 4% of the total energy consumption today. At the same time, Ukraine has favorable climatic conditions and fertile soils, as well as areas of agricultural land, which make it possible to meet the demand for food products both for domestic consumption and for export. The tendencies towards the depletion of traditional fuels and their rise in price determine the diversification of the fuel and energy sector and the search for reserves for the production of their own environmentally friendly energy. The paper describes the characteristics of energy crops for biofuel production. The advantages of growing bioenergy crops were presented. The characteristics of energy crops in relation to growing conditions were determined. Ukraine has a great potential for growing the most popular energy crops: miscanthus, switchgrass, energy willow, poplar without endangering food security but this potential has not been realized yet.
Energy needs are determined by three main factors: population growth, the economic development of society, and the scientific and technical level of production processes. These needs are increasing year by year in the world and in 2018 they exceeded 13.5 billion tons of oil equivalent. More and more countries are developing and implementing plans and strategies for significant coverage, within 50-100%, of their energy needs through renewable energy sources. The findings of this study revealed that Ukraine’s energy demand per year is 200 million tons of oil equivalent of energy resources. Currently, the share of renewable energy in the structure of energy consumption in Ukraine is 4.4%. The authors also acknowledged that at the same time, 115 million tons of agricultural plant waste and about 97 million tons of animal waste are generated annually in Ukraine, which makes it possible to produce 7.21 million tons of oil equivalent and 2.2 million tons of oil equivalent, respectively from these. The study found that the production of biofuels from agricultural waste will have social, economic and environmental effects. An efficiency matrix was constructed by the authors to determine these effects. Using the SWOT method of analysis, factors that will affect the development of biofuel production from agricultural waste were determined.
Today, the issues of waste management are complex, because they relate to various aspects – resource conservation, environmental safety of mankind, ensuring competitiveness at micro, macro and mega-levels. The study is devoted to the analysis of the potential, awareness and current state of use of agricultural waste to ensure energy autonomy of agricultural enterprises of Ukraine on the basis of the experimental study, conducted by the authors using a mixed method. The main tool in the study was the survey developed by the authors, which was filled out by the owners of agricultural enterprises in Ukraine. The development of the survey was accompanied by the authors' hypotheses regarding the need for energy autonomy of agrarian enterprises; main sources of information on opportunities and state support for energy use of waste; potential and current state of bioproduction in agrarian formations. Authors acknowledged that both the crop and livestock industries lead to the generation of waste that has the potential to produce biofuels (solid – pellets, briquettes; gaseous – biogas). The study confirmed that the costs for providing agrarian enterprises themselves with fuel and energy resources in Ukraine are quite high, and the bioenergy potential of waste to replace traditional energy resources is practically not used. Further studies will cover a range of questions regarding the extension of the geography of the survey to the whole territory of Ukraine, the specification of hypotheses based on the preliminary questionnaire, the hypothesis testing and the correlation between different indicators of the agrarian waste potential for biofuel production and the efficiency of substitution of traditional energy with biofuels.
Ukraine’s agriculture is a leading sector of the national economy. Ukraine has a significant area (603628 km2), 70.9% of which are agricultural lands. Quality soil and good climatic conditions create favorable conditions for the development of crop and livestock production. The generation of a large amount of organic waste from agriculture opens wide opportunities for the development of the biogas technologies. The aim of the paper is to identify the main waste management trends in Ukraine based on data on waste generation and waste management and to calculate the strategic potential of agricultural waste as a feedstock for biofuels production. The resource potential of crop, livestock and processing waste has been considered and the necessity of its use for energy purposes has been substantiated. It has been determined that the greatest potential of agricultural waste that can be used for biogas production in Ukraine is concentrated in crop production. The livestock industry and processing enterprises also have a powerful feedstock base for biogas production. It has been determined that the agroindustrial sector of Ukraine produces significant amount of waste. As a result of the study, it has been found that the potential volume of biogas production from agricultural waste can replace 36.1% of natural gas consumption in Ukraine.
The article is devoted to solving the problems of recycling in Ukraine, as the accumulation of waste every year becomes more and more threatening. Waste accumulated in landfills occupies 7 percent of the territory of Ukraine (more than 43 thousand km2), which simultaneously leads to pollution of water, soil, air and the deterioration of the ecological and economic situation in general. The experience of European countries in dealing with waste indicates the complexity and effectiveness of measures for their effective management, which is not currently available in Ukraine. The main objective of the article is to provide proposals on improving the processes of safe waste management in Ukraine, taking into account the EU experience and identifying a number of measures that will facilitate the effective management of solid household waste in Ukraine. The object of the research is municipal solid waste as a source of valuable secondary raw materials, as well as an energy resource. The research methodology includes the application of the dialectical approach and the methods of economic analysis: abstract-logical, statistical-economic, tabular and graphic, monographic, economic-mathematical (extrapolation method). The article highlights the ecological and energy efficiency of the secondary use of a valuable resource of solid household wastes. A scheme for organizing the effective utilization of solid household waste is proposed, the implementation of which is of practical importance in the implementation both at the level of individual communities and the state as a whole.
