This article analyzes the perspective of implementing target indicators in the green transition of the agro-industrial complex of Ukraine. It is established that soil degradation has acquired a global dimension, and it has become a serious problem of a socio-economic nature due to the military actions in Ukraine. Analysis of the state of agricultural land was performed based on the following indicators: humus content in the soil, volume of application of organic and mineral fertilizers, pesticides, land area under organic production, etc. The purpose of the study is to assess the impact of implementing waste-free biofuel production technologies at the enterprises of the agro-industrial complex to achieve eco-goals of the European Green Deal. The article outlines target guidelines for achieving eco-goals of the European Green Deal. Further steps necessary to overcome current problems in compliance with the norms of the EU legislation on environmental protection at agricultural enterprises for the sale of agricultural products to European markets are proposed. It has been scientifically proven that the agro-industrial complex of Ukraine has an untapped potential for reducing greenhouse gas emissions through ecological modernization and implementing waste-free production technologies. It is suggested to use biogas plants as a promising means of solving the problems of waste disposal, improving the ecological situation, reducing energy dependence, and increasing soil fertility. The effectiveness of applying organic fertilizer, namely digestate, a by-product of methane fermentation, as biofertilizers at agricultural enterprises has been proven. Recommendations are provided regarding soil regeneration measures in Ukraine in the future.

Diesel generator engines operate in wide load modes; therefore, it is necessary to change the percentage of the mixture of diesel and biodiesel fuel depending on the operating mode of the engine; this ensures its technical performance at the required level in all operating modes, including starting and stopping the engine. This article describes an algorithm for the operation of a diesel generator and an algorithm for determining the composition of the fuel mixture. During the study, the ratio between the components of the mixture changed, taking into account the load modes of operation of the diesel generator, indicators of fuel supply and the formulation of the fuel mixture to ensure optimal values of technical and economic indicators. To assess the efficiency of the flow of working processes in a diesel cylinder, their duration was selected, which is estimated by the duration of the processes of fuel injection, evaporation and combustion. Using the dynamic regulation of the composition of the diesel and biodiesel fuel, the total fuel consumption increased by 5.9%, but the cost of purchasing the fuel is reduced by 10% (at prices as of November 2021) and by 14.6% (based on prices as of the beginning of 2022) compared to engine operation with diesel fuel. This confirms the expediency of using the dynamic adjustment of the composition of the fuel mixture. In addition, even higher economic indicators can be achieved by using an autonomous power plant with a diesel power capacity higher than the generator capacity.
