“…Waste disposal can be accompanied by the production of liquid and gaseous biofuels, the production of biohumus and preparations that increase the yield of crops and food products. Therefore, the rational use of natural resources and the efficient integrated use of grown raw materials require the introduction of innovative scientific measures aimed at maximizing the effective extraction of useful substances from agricultural waste [1][2][3][4][5][6].…”

Agro-industrial waste at all stages of agricultural production, processing and consumption increases annually and reaches an enormous level. Agricultural waste is often rich in valuable biologically active substances, therefore, it is important to consider methods of its efficientprocessing. Waste recycling is required to reduce the negative impact on the environment, minimize waste and increase the efficiency of the use of raw materials. The paper presents the results of chemical analysis of phytogenic waste: potato and carrot tops. Potato and carrot top wastes are considered the agricultural waste. The sown areas of these crops are huge. All this was the reason for choosing the aboveground part of potatoes and carrots as objects of study in order to obtain a sufficient amount of biologically active substances. Lipids were extracted from potato and carrottops by hexane extraction, washed, and the unsaponifiable substancesweresplit by column chromatography on silica gel. The fraction composition was determined by physicochemical methods. The results of the experimental study showed that potato and carrot tops contain a significant amount of biologically active components, among which triterpene compounds present a particular interest. Triterpene compounds have properties that can help to fight against oncology and viral diseases: prevent inflammation, inhibit the active division of cells and the growth of pathogenic neoplasms, activate programmed cell death, which makes it possible to recommend the aboveground part of potatoes and carrots as a cheap source of biologically active substances for the pharmaceutical and perfumery industry.

“…In accordance with the requirements of safety rules, deviations of the methane concentration from the limits of the norm, even of a single, short-term nature, are completely unacceptable, since they can lead to an emergency mode [23]. When monitoring such an object, it is important not to miss any, even rather rare, excess of the maximum permissible level [1][2][3][4]24].…”

To solve the problems of controlling the gas-dynamic processes of production areas and air distribution in the ventilation network, their mathematical description is required, which can be obtained only on the basis of a detailed study and determination of the parameters and characteristics of gas-dynamic processes and regularities of air distribution. The mathematical description of the production ventilation system is complicated by the fact that the variables that determine the state of the control system are random functions of time. Therefore, the main attention should be paid to determining the probabilities of the characteristics of aerogasdynamic processes. The mathematical description of the ventilation of the production area into static and dynamic characteristics was the basis for the development of an optimal control algorithm for the production area. The control algorithm for the ventilation of the mining area consists of subalgorithms for controlling the parameters of the mine atmosphere, primary processing of the received information, and generating control actions. Their development is possible on the basis of research and mathematical description of gas-dynamic processes and methods for controlling the parameters of the mine atmosphere. Effective control of gas-dynamic processes in production areas is possible only when considering the entire ventilation system, due to the interconnectedness of aerodynamic parameters. The task of optimal air distribution control in the network is to ensure the required airflow rates for ventilation, determined as a result of solving the first problem with minimal energy costs for ventilation.

For sustainable management of natural resources and effective integrated use of the raw materials, it is necessary to introduce into production innovative developments for the effective extraction of valuable substances from production waste. Waste recycling is crucial to reduce the negative impact on the environment, minimize waste and increase the efficiency of using raw materials. The paper addresses the problem of environmental pollution by grape processing waste. The results of chemical analysis of CO2 and alcohol extracts from grape processing waste, including grape pomace, are presented. For the study, samples of carbon dioxide extract from white and red grape pomace were isolated. In carbon dioxide extracts, indicators of oxidative spoilage, mass fraction of unsaponifiable substances and fatty acid composition were determined. It is shown that for the most efficient extraction of biologically active substances from grape pomace, a two-stage extraction should be carried out: CO2 extraction and extraction with an alcohol solution. The experimental results indicate that the secondary extraction from grape pomace and its individual components with liquefied carbon dioxide results in the formation of easily decomposable waste and extraction of a lipid fraction containing valuable substances that can be used in the food and cosmetic industries. The results obtained show that the use of a 70% alcohol solution is technologically substantiated for obtaining extracts from grape pomace with a highest content of phenols, flavonoids, anthocyanins and tannins.
