Neglect of soils leads to their degradation, worsens useful properties, and reduces fertility and productivity. (Research purpose) The research purpose is in conducting a comparative analysis of technologies for treating degraded soils, taking into account the economic feasibility of their restoration in non-black-soil regions of Russia. (Materials and methods) The article shows the main technological scheme of restoration of degraded soils. Authors have identified the main groups of land that are located in non-black-soil regions of Russia. (Results and discussion) The article presents the need for equipment, economic and labor costs for the restoration of each type of land in the non-black-soil regions of Russia. Authors took into account that the salary of machine operators depends on the time of direct execution of the task. It was found that the restoration of virgin and fallow lands was the most preferable from the economic, energy-saving and environmental points of view. The article shows that the restoration of pasture areas exceeds the cost of processing virgin lands, but the number of necessary machine and tractor units is comparable to work on virgin lands. Authors recommend to develop the soils with woody and shrubby vegetation in the first place, starting with land occupied by young plants. It is necessary to take into account the criteria for the fertility of the soil layer. It was found that soils with a small excess of moisture have small cost of its development, while on heavily swampy soils the cost of work on their development is many times higher than the cost of restoring other types of land. (Conclusion) The article shows that the restoration of neglected land is a necessary condition for improving the provision of human needs for food and a number of industrial goods. First of all, it is necessary to develop land that requires minimal investment of economic and labor costs.

The soils that are subject to restoration include virgin and fallow lands, neglected pastures, soils overgrown with shrubs and young trees, swampy, with admixtures of hummocks and debris. The article shows the shortest period of restoration of virgin and fallow lands. (Research purpose) The research purpose is in comparative analysis of the need for equipment, economic and labor costs for the restoration of fallow lands using traditional and proposed by VIM technologies. (Materials and methods) Authors determined the indicators that characterize the properties of the soil for its restoration. It has been taken into account that for the treatment of this fallow soil, it is preferable to use combined aggregates or equipment with replaceable working bodies. Authors have compiled a set of aggregates for the proposed by VIM technology for soil recovery. The article shows the most productive and economically viable technology. The calculations of the cost of the necessary units, fuel and lubricants consumption, and labor costs are presented. (Results and discussion) It was determined that the restoration of fallow lands using the technology proposed by VIM reduces the cost of using the machine and tractor fleet by 35 percent by reducing the number of agricultural machines, fuel and lubricants by 17 percent, and the labor costs by 12 percent. The article shows that the efficiency of implementing the technology proposed by VIM for restoring virgin and fallow lands without shrubs and trees can reach 28 percent or more. (Conclusions) From the point of view of ecology, resource and energy saving, the most preferable are soil-processing combined units or agricultural machinery with changing working bodies (including those that perform various tasks). When restoring a 200-hectare section of fallow land with a heavy clay mechanical composition on soils that have not been treated for four consecutive years, according to the proposed VIM technology, the cost of restoration decreased by an average of 28 percent.

Abstract Tracking devices are increasingly used in automatic control systems for mobile agricultural machines. Many elements are regulated by standards and specifications, and it is of scientific and practical interest to establish a correspondence between the reliability of restored parts and connections with the reliability of machines. This is due to many reasons, one of which is a decrease in the technical potential of the village: the composition of the machine and tractor fleet is decreasing, the physical and moral wear of equipment is progressing. Repair and maintenance of cars due to the price arbitrariness of intermediary structures, mainly on the part of collective farms and farms. For this reason, the reliability and reliability of the machine park of rural producers remain low, negatively affects the agrotechnical timing of mechanized work, their cost. In accordance with the standard technology, standards of labor costs for the repair of machines, standards for the consumption of materials needed for repair, and standards for the consumption of spare parts were created. The economic feasibility of restoring parts is usually assessed by comparing the cost of a new part and the cost of repairing a worn one.

The main goal of agriculture is to obtain products, but its processing is no less important. At processing enterprises, grinding and cutting are the most important technological process. (Research purpose) The research purpose is in analyzing the market of knives of processing machines, their pricing, resource and describing the economic efficiency of applying strengthening coatings. (Materials and methods) Authors used a digital method of searching through the Internet for enterprises that produce knives for processing machines, types of knives and their characteristics. (Results and discussion) Specialized knives are used for grinding products in the industrial plants. Since knives are a consumable item, the technology of their replacement is subject to requirements for the simplicity of the process, low cost and low labor cost. These requirements, together with the specific ones determined by the technology, form the design of the knives. The efficiency of the processing machine directly depends on the state of its working organs. Replacement of worn-out elements is accompanied by large labor costs, which leads to a decrease in labor productivity and to downtime of equipment in repair, and ultimately − to a decrease in the profit of the enterprise. (Conclusions) The hardening of knives by the borating method using high-frequency heating will increase the productivity of agricultural machinery and will give an economic effect up to 0.32 billion rubles due to an increase in the resource and a lower cost of manufacturing hardened knives compared to imported ones. By reducing the cost of domestic knives, you can get savings on one knife of 1960 rubles, provided that you refuse to purchase imported knives.

Abstract. Problem. When designing and building pavements, it is necessary to make full use of local low-strength stone materials reinforced with inorganic binders (cement, lime, activated ash, etc.). The economic feasibility of using cement soils for paving in areas not provided with local stone materials is particularly significant. Under these conditions, the cost of 1 m² of cement-soil layer is often 1.5-2 times lower than the cost of 1 m² of a uniform layer of imported materials. layer of imported materials. When using the technology of soil strengthening with inorganic binders, there is no need for a significant amount of transport, as it is possible to strengthen the local soil, which is located nearby, and only binders can be delivered to the work site. It is possible to unload cement in the car for distribution of binder directly on a place of carrying out works. Strengthening local soils can provide a solid foundation. Soils suitable for cement hardening are much more common than stone materials. The strength of coarse-grained soils depends on the constituent rocks and the density of laying. Fragments of igneous rockshave the greatest strength, sedimentary rocks have the lowest. The most active part of the cement-soil mixture, which provides the creation of a new structure of the reinforced soil, is cement. As a result of the interaction of cement with water, with salts present in the soil and partially with the fine part of the soil, a new water-resistant crystallization structure appears in the strengthened soil. The strength of this structure is determined mainly by the composition and quality of cement. During soil treatment with cement, hydration processes, as well as other chemical reactions will increase or slow down dependingon the chemical and mineral compositions of cement, the nature of the soil and its physicochemical state at the time of treatment. When strengthening soils with cements of the same brands, but of different mineral composition, cement soils with different properties will be obtained. Therefore, the final decision on the suitability of cement and its dosage is made based on the results of tests of cement soil samples. In each case, the decision to use highquality cements or additives that increase thestrength and frost resistance of the cement soil must be economically justified.

When repairing and replacing electrical wiring in enterprises, the main difficulty is the lack or poor quality of documentation, plans for conductors laying. Distinguishing wires (cables) and their cores by the color of the shells or using tags attached to the ends is difficult if the shells have the same color and there are no tags. Devices and technical solutions used to identify wires and cables do not allow recognizing conductors without breaking the electrical circuit, removing insulation, and de-energizing the network. Searching for the right conductor is a time-consuming operation. (Research purpose) The research purpose is developing a new microcontroller device for identifying wires using an acoustic signal. (Materials and methods) Literature sources has been searched for devices for conductors identifying. (Results and discussion) The article proposes a method that involves feeding an acoustic signal to a wire at one point and capturing it at another, in order to recognize the desired wire. The article presents results of comparison of the developed microcontroller device for identifying conductors using an acoustic signal with known devices and methods for conductors recognizing. (Conclusions) The article reveals the shortcomings of existing methods and means of identifying wires and cables. Authors performed a theoretical calculation of the sound pressure in the conductor at a given distance. The article presents the calculation of speed of acoustic waves in conductors with different types of insulation. Authors designed a microcontroller device for identifying conductors using an acoustic signal and tested it. It was determined that the device increases the safety of work, reduces the cost of operating internal wiring and identification time; eliminates the violation of wire insulation, the need to disable electrical receivers. The convergence of theoretical calculations and experimental data was shown.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

AbstractThe management of municipal solid waste is a major logistic and environmental problem worldwide. Nonetheless, the organic fraction of municipal solid waste (OFMSW) is a valuable source of nutrients which can be used for a variety of purposes, according to the Circular Economy paradigm. Among the possible applications, the bioproduction of a biodegradable polyester, poly(3-hydroxybutyrate) [P(3HB)], using OFMSW as carbon platform is a promising strategy. Here, an economic and environmental assessment of bacterial P(3HB) production from OFMSW is presented based on previously published results. The SuperPro Designer® software was used to simulate P(3HB) production under our experimental parameters. Two scenarios were proposed depending on the fermentation medium: (1) enzymatic hydrolysate of OFMSW supplemented with glucose and plum waste juice; and (2) basal medium supplemented with glucose and plum waste juice. According to our results, both scenarios are not economically feasible under our experimental parameters. In Scenario 1, the low fermentation yield, the cost of the enzymes, the labour cost and the energy consumption are the factors that most contribute to that result. In Scenario 2, the cost of the extraction solvent and the low fermentation yield are the most limiting factors. The possibility of using process waste as raw material for the generation of other products must be investigated to enhance economic feasibility. From an environmental viewpoint, the photochemical oxidation potential (derived from the use of anisole as extraction solvent) and the generation of acid rain and global warming effect (caused by the burning of fuels for power generation) are the most relevant impacts associated to P(3HB) production under our experimental parameters.
