The paper presents the dynamics of utilization of construction waste generated in the implementation of construction work in Ukraine. The problem of recycling construction waste is due to significant amounts of construction waste in Ukraine, their annual growth and negative impact on the environment. The experience of European countries regulating their activities using construction waste or disposal is presented. Which due to the improvement of technology and legislation were able to achieve a very high level of recycling construction waste.
The subject of research is the system of waste management in Ukraine, the object is construction waste. The purpose of the work: assessment of the negative impact on the environment in the disposal of waste construction activities. Research objectives: to assess the negative impact on the environment of waste construction activities; to estimate the potential level of reduction of the negative impact on the environment in the application of technologies for the disposal of construction waste. The urgency of the work is determined by significant volumes of building waste construction in Ukraine, their growth and negative impact on the environment. Measures for collecting, storing, temporarily storing, moving (transporting), processing, using, disposing, and disposing of construction waste should reflect complete and reliable information, comply with the current sanitary and environmental requirements, as well as the principles of the most complete utilization of secondary raw materials (wastes).
However, a number of factors have been identified that must be considered when constructing processing plants. When crushing, a significant amount of dust is formed, which is represented by silicates, aluminosilicates and calcium and magnesium hydrosilicates. Calculated and analytical studies of emissions of pollutants during crushing showed that the concentration of dust at a distance of 200-220 m from the source of emission exceeds the MAC. In this regard, the minimum possible size of the C 33 from these sources of emissions of pollutants into the atmosphere is 300 m (in the absence of dust suppression systems). This factor is essential when choosing a site for the location of a remote control, and also limits the possibility of using installations in conditions of dense housing development. Another significant factor is the level of noise exposure created during the operation of the crushing plant.
