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 air basin of cities is subject to significant pollution, including waste gases of power plants. However, they are a necessary element of the life support system of urban areas and cannot be taken outside the city. Therefore, the problem of proper selection of structural elements and operational characteristics of the process and system for reducing air pollution becomes very important. Our scheme of transformation of pollutants within the framework of the physical and energy approach allows to determine possible types of effects on gaseous pollutants, to control their behavior in order to reduce stability and, ultimately, to reduce pollution of the air basin.

The article is devoted to solving the current problem - improving the environmental safety of cities by using the specific functions of green plantations in the formation of the green frame belt. Analysis of advantages and disadvantages of existing methodological approaches to formation of "green frames" of cities allowed to systematize, select and scientifically justify estimated criteria taking into account climatic conditions, landscape, impact of anthropogenic factors, efficiency of creation of comfortable habitat and to develop methodology of formation and selection of "green frame" belt of cities.

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.

The authors propose to choose the system of air purification from grain dust, which has the maximum ecological efficiency and energy efficiency, based on the study of the properties of this pollutant. Investigation of the grain dust parameters of the properties of the dispersed phase and dispersion medium, as well as energy parameters will affect the stability of the aerosol, i.e. its ability to resist external influences. Changing the stability of the grain dust aerosol and, ultimately, its destruction due to the separation of the dispersed phase and the dispersion medium, is the purpose of the development of air purification system.

The analysis of the current in the Rostov region of solid waste consumption (TOP). The types for each stage of treatment with top - from the collection of top and ending their disposal, including disposal. The basic shortcomings of the implementation of each stage and the difficulties of the methods each of the stages. The main directions of solving these deficiencies existing in the Rostov region of handling top. In conclusion, it was concluded that the improvement of treatment should start with the top ""change"" consciousness of the people and persuade them to sort waste that will go to the task management system dealing with TOP in order to reduce environmental pollution in urban areas.

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.

In the work pointed out that currently the most common method for the disposal of solid waste production and consumption (JET) is to bury them in landfills. The authors have studied the requirements for the placement of landfills for disposal of municipal solid waste production and consumption and concluded that most of the already existing landfills POMB not in compliance with environmental regulations, and the construction of new landfills have not been fully taken into account environmental aspects and factors. We also study the features of the existing types of landfills for disposal of solid waste production and consumption. In conclusion, the authors concluded that the device ranges JET shall be in accordance with the established procedure for the design, operation and rehabilitation of landfills for municipal solid waste with the obligatory account climatic features of the area in question, geological and hydrological conditions of the terrain and conditions to ensure environmental safety.

The analysis of the main problems in the field of solid waste production and consumption in the city of Rostov-on-Don, determine the most important of them - the lack of separate collection of waste, low level waste recycling, insufficient waste treatment enterprises, inadequate coverage of rural service collection and waste removal, exclusion of large areas under waste disposal, illegal dumping. Studied the current system of handling tvedrymi waste production and consumption in the city of Rostov-on-Don, revealed its priorities, chief among them - increasing the share of industrial waste recycling and reducing the amount of waste to be disposed of. It is concluded that the lack of effectiveness of management of solid waste production and consumption and the need for a radical change in the existing strategy for waste management in the city of Rostov-on-Don.
