As a result of the parametric analysis of the subsystems that make up the system, the main groups of environmental parameters that are subject to the effects of technological processes of road repair were identified. The mathematical model of cause-effect relationships in the system under study allows identifying the main aspects of environmental impact during technological processes of road construction and reconstruction. Its application in environmental impact assessment allows forming a criteria base for environmental impact assessment. The article defines the relationship between the process of performing a certain stage of repair work on the project of construction of the highway of state importance N-31 Dnipro – Tsarychanka – Kobeliak...

By turning waste into raw materials and materials, recycling allows you to save on natural resources, create new jobs and thus reduce the unemployment rate in the country, and reproduce competitive production. The sector of recycling of secondary resources creates a social effectcontributes to the creation of new jobs. The recycling generates demand for low, medium and highly skilled labor.

The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company’s activity and proposed an environmental policy as an essential element for the implemen...
Practical experience of solid domestic waste (MSW) management in Ukraine and developed countries ... more Practical experience of solid domestic waste (MSW) management in Ukraine and developed countries is analyzed. Theoretical volumes of MSW accumulation taking into account statistical factors are studied. The generalized method of MSW accumulation volumes allows forecasting their formation from the factors and evaluating the morphological composition of MSW in the region. The system for optimizing community waste management at the collection and disposal stage with the quality of the optimality criterion has been proposed. The degree of recycling and the costs of collecting and transporting waste should be taken as a criterion for optimising the urban waste management system at the collection and disposal stage. The quality analysis of the waste management system in the Zhytomyr region made it possible to identify the main problems in municipal waste management and the main reasons for their occurrence. The survey shows that the main problem in the area of waste management is the low ...

Quantitative analysis of the emergence of the risk of environmental hazard is carried out in accordance with the "Methodology for determining the risks and their adopted levels for the declaration of safety of objects of high danger", which determines the procedure for conducting a hazard analysis and risk assessment of high-risk objects, which is carried out through the definition of the probability of undesirable consequences of accidents on based scripts for their emergence and development. For the risk assessment, a logical-probabilistic hazard response scheme in the form of a "failure tree" is constructed and analyzed, which is a form of an ordered graphical representation of the logical-probabilistic connection of random event...

The primary method of magnetite ore beneficiation involves successive steps of crushing, grinding, and magnetic separation. Reverse cationic flotation is used at the final stage to remove silicate and aluminosilicate impurities from the magnetite concentrate and reduce silica content to 1–3%, depending on metallurgical processing route (electrometallurgy, direct iron reduction). In view of the stringent demands of the magnetite concentrate grade, before flotation, the ore is currently routinely ground down to a particle size below 35 µm, and magnetite particles are ground to a size below 10 µm. This significantly reduces the efficiency of flotation and increases iron loss in the tailings due to the hydraulic report in froth being up to 15–25%. Combined microflotation (CMF) looks to be a promising method of increasing fine-particle flotation efficiency, as it uses relatively small amounts of microbubbles alongside conventional coarse bu...

The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company's activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. The studies conducted with the aim of determining the motor transport enterprise sewage composition revealed an excessive content of polluting chemical substances, namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of using carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of wastewater of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing the environmental fees and penalties.
