Summary: The deficit and dependence on imported energy resources, mineral fertilizers, their price growth, negative changes in climatic conditions, pollution of water resources, air and soil, withdrawal of a large part of agricultural land due to hostilities aff ect the functioning of the agricultural sector. This creates threats to ensure food, energy and environmental security of Ukraine. As part of the implementation of the Sustainable Development Strategy in Ukraine, which is based on ensuring national interests and fulfilling international obligations, it is envisaged to overcome the imbalances that exist in particular in the environmental sphere, to harmonize global climate change trends with international standards. The priority is land resources, agriculture, forestry, water resources, bioenergy, biodiversity. The scientific article examines the provision of rational use of natural resources thanks to effective waste management. The concept of a resource-saving agro-industrial complex was formed due to the development and implementation of bio-organic technologies for growing agricultural crops for the production of biofuels from agro-biomass and animal husbandry waste. The agro-technological aspects of ensuring the energy independence of the industry and the formation of the country`s food security have been proven. The main areas of effective use of agrobiomass and utilization of agricultural waste for the production of biofuels have been determined. On the basis of the researched state of supply of energy resources of the agricultural industry and assessment of the available potential of the industry in agrobiomass, the theoretical volumes of biofuel production to ensure the energy independence of the industry are calculated. A comprehensive analysis of the European experience in the production of biogas from crop and livestock waste and the use of digestate obtained on the basis of anaerobic fermentation in a biogas plant has been developed. The purpose of the study is the analysis of agro-technological aspects of digestate production, taking into account the international experience of adaptation to climate change in order to guarantee the reduction of the degradation processes of the soil cover of Ukraine. The subject of analysis was bio-organic technologies of digestate production with the intention of using it as fertiliser. The study research methodology is based on experimental studies of scientific topics: «Development of bioorganic technologies for growing agricultural crops for the production of biofuels and ensuring the energy independence of the agricultural sector».
