As a result of energy assessment of a pneumatic sieve separator for agricultural crops it was determined that the specific energy consumption of the experimental pneumatic sieve separator was 0.18 kW·year·t−1. It is lower than in case of its domestic and foreign equivalents. For instance, the specific energy consumption of the separator of preliminary grain purification called SPO-50 (Ukraine) is 0.31 kW·year·t−1, and that of the machine of preliminary grain purification called MPO-50 (Russia) is 0.38 kW·year·t−1. Specific energy consumption of a pneumatic sieve separator is 1.72-2.11 times lower than in case of its domestic and foreign counterparts.

“…But generally accepted calculations have certain drawbacks -often enterprises do not calculate the net profit, thus they do not evaluate their own factors of production and the efficiency of their use. This is particularly negative for farms from an economic point of view, where many of their own production factors are involved (Kovalenko and Kovalenko, 2019;Mykhailov et al, 2020;Neumann et al, 2010).…”

The paper discusses competitiveness of the agro-industrial sector, which is a multifaceted concept that characterizes its ability to compete in both domestic and foreign markets. Ukraine has significant opportunities to develop the agricultural sector and turn it into a highly efficient branch of economy. Favorable soil and climate conditions, and fertile land contribute to its further development, obtaining agricultural crops in volumes sufficient to meet domestic needs and build export potential. The production process of agricultural goods takes longer than in industry. Therefore, at the stage of determination of the production program of an agricultural enterprise, it is very difficult to respond on time to changes in consumer demand and increase the product competitiveness within the already established production schemes in the markets. Therefore, the purpose of our study is to evaluate the effectiveness of growing the studied crops in a typical farm in Central Ukraine and offer a roadmap for making management decisions when planning a production program. For this purpose, a method based on calculations of the gross margin, total expenses, production thresholds, profitability, and payback of production factors was chosen.

“…Therefore, plant waste can be considered an important potential fuel for the development of small power engineering in agricultural areas. Thus, compared to other types, the energy use of plant waste is the most accessible, economically effective, and also has ecological and social and economic advantages (Mykhailov, 2020).…”

The analysis of statistical data showed that a large amount of plant waste is generated annually in oil and fat production plants, which must be processed and reused. The paper analyzes the problems of reusing sunflower oil production waste, which is characterized by a relatively high energy value: 1 ton of plant waste is equivalent to 0.625 tons of conventional fuel. According to the mathematical estimation, the actual total amount of impurities is 7.29%, in which major impurities constitute 25.7%. Studies have shown a high probability of oil – containing impurities – 37.25%. Therefore, it is recommended to process such impurities into fuel briquettes and technical oil to increase the profitability of sunflower oil production. For example, at the annual load of technological equipment of the Melitopol Oil Extraction Plant, in 250 days, at a daily processing capacity of 550 t˙day-1, an annual profit of 560,000 EUR is obtainable from the sunflower grain impurities processed into fuel and technical oil.
