The problem of managing municipal solid waste (hereinafter referred to as MSW) is annually complicated, due to the increase in the mass / volume of generated waste, the transformation of its composition and properties, the lack of economic resources in many countries for processing the bulk of the waste, and other reasons. The largest amount of MSW is generated and accumulated in residential and public buildings of various amenities and purposes, in enterprises, on the streets, in courtyards. Untimely disposal and disposal can lead to significant environmental pollution (hereinafter referred to as OS). One of the main stages of MSW management is waste collection. Therefore, the article presents a solution to the urgent problem of improving the environmental safety of urban areas with the aim of further using waste for energy supply based on the choice of an environmentally friendly and energy-efficient engineering system for collecting MSW.

The article is devoted to the process of air pollution as a result of the production and application of paints and varnishes used in the construction industry. In the process of pollution in the air enters the polluting aerosol (toluene), which is a toxic substance. The whole process of pollution is considered step by step, where at each stage the contaminating aerosol changes its parameters of properties. The result of the analysis of the pollution process is a physical model and mathematical dependence describing the essence of this process.

The article is devoted to the analysis of the physical essence of the process of reducing air pollution for the woodworking shop of the enterprise serving the objects of urban construction, within the framework of the physical and energy approach. According to this approach, wood dust is considered from the position of the theory of dispersed systems, which changes its properties under the influence of external dispersed systems. The whole process is gradually illustrated by a physical model of the process of reducing air pollution, as well as a scheme of transformation of the dispersed system (dust aerosol) in the process of reducing air pollution.

The article analyzes the theoretical approaches associated with the assessment and selection of the best efficiency of the complexes of methods and means to reduce air pollution in the operation of power plants as objects of urban economy. The advantages and disadvantages of each approach are considered. The physical-energy approach is highlighted as the most acceptable, in which the ecological efficiency and energy efficiency are the main criteria for the evaluation and selection of measures to reduce air pollution.

The article deals with topical issues of mercury waste disposal. The analysis of the possibility of secondary use of demercurized cullet under the condition of maximum extraction of mercury concentrate. On the basis of physical and chemical properties of mercury, a comparison of two methods of demercurization, during which it was found that the technology of thermal demercurization will reduce the percentage of remaining mercury in cullet.

In the article the modern approach to the assessment of the acoustic impact on the adjoining residential zone under construction or reconstruction of airport complexes. While the features of sources of acoustic impact as ground handling and flight operations. Assessment of acoustic impact on the adjoining residential zone under construction or reconstruction of airport complexes, according to the authors, involves several stages. The implementation proposed by the authors of the stages of the assessment of acoustic impact will allow to identify the zones of acoustic discomfort and plan a set of measures aimed at reducing noise in those areas and thus enhance environmental validity under construction or reconstruction of airport complexes.

In article authors considered organic types of fuel as the most widespread sources of obtaining thermal and electric energy at the enterprises of fuel and energy complex. The prevailing types of organic fuel – natural gas, coal, fuel oil are revealed, and also the composition of flue gases depending on a type of the burned organic fuel is analysed. So, when burning natural gas the main polluting substances are nitrogen oxides and carbon oxides. When burning liquid fuel oxides of sulfur and ashes are added to them. Coal burning, besides above-mentioned substances, leads to receipt to the air basin firm particles, particles (flying ashes) consisting from the zolovykh, not burned down solid fuel and soot. Negative impact of the enterprises of fuel and energy complex on environment components is investigated. In the conclusion authors drew a conclusion that, in comparison with other types of organic fuel, burning of natural gas does the minimum harm to environment.

In the article the authors propose a method for the implementation of environmental-economic evaluation of acoustic impact on the urban environment. More than 80% of the population lives in conditions of excess acoustic load. The main sources of acoustic impact for the majority of urban areas are rail and air transport, road transport, industrial enterprises. At the design stage of projects to reduce the acoustic impact of the urban environment, as a rule, there is a need for ecological-economic assessment to justify the implementation of noise protection measures. The proposed method allows to estimate the annual damage in rubles from acoustic impact in the urban environment from the various "regulated" sources of noise. Under "regulated" sources of noise, the authors imply any source, whose contribution to the total level of acoustic impact is reduced as a result of implementation of the evaluated activities. The authors proposed implementation methodology of ecological-economic assessment of acoustic impact on the urban environment can be used in urban design, in justifying the choice of measures for the suppression of acoustic effects in the existing buildings, the choice of optimal variants of a new technology that can reduce the acoustic impact on the residential premises, etc.

Ecological features of the impact of landfills on the environment in the regions where they are located In the article the analysis of environmental problems arising from the placement and operation of solid waste landfills. The most important of them include negative impacts on various environmental components in the area of polygons. The result of this impact is the degradation of the existing ecosystem. Therefore, landfills should be considered as secondary sources of environmental pollution in the urban environment. Conducted detailed analysis of the technological operations of the process of waste disposal and assessment of the environmental impact at each stage. In the result of the analysis revealed that the greatest impact on the environment provides a plot of discharge, where discharged and compacted waste. This requires further investigation to develop appropriate engineering and environmental activities.

In the article the analysis of the environmental features of the main stages of solid waste management consumption in the Russian Federation. Each stage has environmental and economic features of the implementation. Ecological features suggest danger in the form of toxic compounds, heavy metals, pathogenic microorganisms, as well as the negative impact of waste on the environment (aesthetically unattractive, unpleasant smell of the places collection of solid waste). In addition to environmental characteristics, the waste management system there are many economic issues related expenditure in a system of solid waste management consumption. Thus there are costs both before and after the operation of waste treatment facilities.
