Global climate change due to the greenhouse effect has become a major international and political issue. Carbon dioxide is recognized as one of the main factors enhancing the greenhouse effect. Other known greenhouse gases together account for about half of global warming. Excess in the atmosphere of greenhouse gases and aerosols, solar radiation and the properties of the earth’s surface change the energy balance of the climate system. Agriculture is a significant source of greenhouse gas emissions, as livestock and crop production are associated with emissions of carbon dioxide, methane and nitrous oxide. According to reports of emissions that governments regularly submit to the Secretariat of the United Nations Framework Convention on Climate Change, agriculture accounts for about 15% of global greenhouse gas emissions. On the other hand, greenhouse gases change the climate and thus affect agricultural production. At the same time, the share of agriculture in world GDP is about 4%, which indicates that the carbon intensity of agriculture (emissions per unit of output) is quite large. Urgency of ecologization of agriculture of Ukraine is conditioned by worsening of the ecological state of the natural resources, related to the agricultural production, decline of fertility of soils and product quality, by the increase of complex ecologically-destructive influence on the environment. Ecological agriculture is economically advantageous direction of activity with the high level of profitability comparatively with traditional technologies of production. The main direction of agricultural development should be the ecologization of all production processes, which led to the interest and conduct of this study. Purpose. The purpose of the research is to substantiate the theoretical and applied principles of ecologization of agricultural production based on the use of waste-free technologies to ensure energy autonomy of agriculture. The subject of the research is theoretical-methodical and practical aspects of using wastefree technologies for ecologization of agricultural production and ensuring energy autonomy of AIC. Methodology. The research used the following scientific methods: monographic (in studying the theoretical provisions of ecologization of agricultural production and use of waste-free technologies), statistical (in analyzing the state of agriculture and the use of waste-free technologies for renewable energy, reducing fossil fuel consumption and how consequence, ecologization of agricultural production) computational and constructive (in substantiating the management practice of resource conservation in agricultural development on the principles of waste-free production), various methods of economic and statistical method (statistical observation, comparison, tabular, graphical) – in the development of visual illustrations; abstract-logical – to summarize research results and formulate research conclusions. Practical implications. The impact of biogas production from livestock waste in Ukraine on the ecologization of AIC is analyzed. Measures have been proposed to promote the development of waste-free biogas technologies in Ukraine to ensure energy autonomy of the agro-industrial complex. Value/originality. The economic efficiency of replacing natural gas with biogas formed from agrobiomass is determined. The author’s bioenergy model of biogas production from agricultural waste is proposed. The analysis of the advantages of biogas production from agrobiomass for ecologization of agricultural production was further developed. The enterprises of Vinnytsia region, which have the largest capacities of biogas production from agrobiomass, are characterized. The study is based on the tasks of applied research on the topic: “Development of scientific and technical support for energy autonomy of the agro-industrial complex based on environmentally efficient use of agrobiomass for biofuel production”, state registration number 0122U000844.
