Проведен анализ ситуации, сложившейся при совмещенном вывозе твердых коммунальных отходов (ТКО). В связи с тем, что используемые на сегодняшний день конструкции мусоропроводов не предназначены для селективного (раздельного) сбора ТКО, исследована возможность реновации и модернизации мусоропровода и мусоросборной камеры для селективного сбора ТКО в существующем многоквартирном доме. Авторами предложен вариант модернизации существующей системы сбора мусора, заключающийся в следующем: в мусоросборной камере располагается несколько контейнеров, вместо патрубка и шибера устроена единая конструкция на все контейнеры, оснащенная заслонками, которые открываются для нужного вида отходов при нажатии соответствующей кнопки на блоке управления. Для домов, в которых нет мусоропроводов, рассмотрена возможность организации уличной контейнерной площадки, предназначенной для селективного сбора ТКО. Для вычисления размеров необходимых контейнеров было проведено исследование по определению масс и объемов разных фракций ТКО, приходящихся на одного человека. По результатам исследования был выполнен расчет по подбору размеров контейнеров по всем видам отходов для мусоросборной камеры и для уличной контейнерной площадки, с определением периодичности вывоза ТКО. Разработан алгоритм по селективному сбору ТКО в существующей жилой застройке. We carried out the analysis of the situation with the combined disposal of solid municipal waste (SMW). Due to the fact that the designs of waste chutes used today are not intended for selective (separate) collection of SMW, the article examines the possibility of renovation and modernization of the waste chute and waste collection chamber for selective collection of SMW in the existing apartment buildings. The authors offer a variant of modernization of the waste collection chamber, which consists in the following: in the waste collection chamber there are several containers, instead of a branch pipe and a gate, a single apron is arranged for all containers, equipped with flaps that open for the desired type of waste when the corresponding button is pressed on the control unit. The possibility of organizing street container platform for selective collection of SMW was considered for the apartment buildings which do not have waste chutes. To calculate the size of the required containers, we conducted a study to determine the mass and volume of different SMW fractions per person. According to the results of the study, a calculation was made for the selection of container sizes for all types of waste for the waste collection chamber and for the street container site, with the determination of the frequency of SMW removal. An algorithm for selective collection of SMW in existing residential buildings has been developed.

The problem of waste management is acute in the Russian Federation. Not enough attention is paid to the systematic studies of their composition and properties. The purpose of the work is to conduct a comprehensive analysis of data on waste generated, to select models for predicting their mass, composition, and properties, to substantiate the feasibility of using exergetic analysis to assess safety and make informed decisions on the management of solid municipal waste management. To predict the volume of waste generation, the following were used: an integrated autoregression model — a moving average and exponential smoothing models. The study of changes in the composition and properties of the municipal solid waste, the choice of technology and the assessment of safety in waste management were carried out using the exergetic method. Its advantages are determined by the possibility of conducting a comprehensive energy-ecological assessment and determining the fire hazard of waste and the processes of handling them. The application of the Holt-Winters model for predicting the mass of the generated waste is substantiated. The analysis of changes in the morphological composition of waste, their distribution by types of economic activity is carried out. The values of chemical exergy of municipal solid waste are determined, and a forecast of its further growth is constructed. The dependences of chemical exergy on the heat of combustion of waste are found. It is determined that it is advisable to consider chemical exergy as a heat engineering characteristic and an indicator of fire and environmental hazard of waste. It is proved that the exergetic efficiency of the incineration process is higher than that of composting and burial. Transportation of garbage from the large cities by road and rail transport for subsequent disposal and recycling can be considered as a forced temporary measure during the development of the branch of industry and the formation of a waste management culture. For the application of the exergy method in the system for ensuring safety when handling solid municipal waste, a data mining system was developed. It is advisable to use the obtained results for the development of safety requirements for the management of production and consumption waste in the Russian Federation.

In modern conditions, the problem of processing and disposal of household and industrial waste, both for the Russian Federation and most countries of the world, extremely aggravated and requires new approaches to its solution. The purpose of the submitted article is to conduct a comprehensive analysis of the system of supporting investment projects in the Russian Federation in the field of processing and disposal of waste. The methodology of the analysis was based on the assessment of the effectiveness of the measures taken in terms of the management of production and consumption waste in the Russian Federation, including a comprehensive study and generalization of existing support measures in the field of waste management and disposal, including those provided by the public law company for the formation of an integrated system of solid municipal waste management «Russian Environmental Operator». The authors summarized the dynamics of education, disposal, disposal and disposal of production waste and consumption in the Russian Federation in 2010-2020. Investment tools are systematized, which have the right to use a public-legal company for the formation of a comprehensive system for the treatment of solid communal waste "Russian ecological operator". The analysis carried out in the course of the study showed that the sphere of solid municipal waste management in Russia is characterized by the presence of many shortcomings and high risks of the implementation of the federal project «Integrated System of Solid Municipal Waste Management», as well as a low level of attraction of private investments in the industry due to high risks implementation of investment projects in the studied area. Conclusions and analytical generalizations made according to the results of the study can be applied in practice during the substantiation and introduction of optimal mechanisms for the support of investment projects in the field of processing and disposal of waste, taking into account the developed hikes to their typing and specification.

The problem of handling solid municipal waste, which is formed during the life of a modern person, is becoming more and more urgent every day. The growth of consumption in modern society entails an increase in the formation of waste, which must no longer be stored, but subjected to recycling or recycling for further use. The solution of this problem, in addition to the technical and organizational component, is possible by forming a culture of solid municipal waste management (hereinafter MSW) among the population, that is, the formation of an ecological culture. The article describes the implementation of the social project “Organization of environmental education and formation of environmental culture of the younger generation in the field of solid municipal waste management” of the Transbaikal State University. During the implementation of the project, the level of environmental culture of schoolchildren was studied by testing in accordance with age. The developed educational and educational program, which includes a set of measures for training and environmental education of general education organization students, helped to motivate them to properly handle waste and form a responsible attitude to nature. Diagnostics formation level of the ecological culture of the younger generation allowed us to state the presence of a problem, namely, the insufficient (low and average) formation level of the ecological culture of general education organization students. Environmental classes and actions allowed students to form an idea of the problems of waste disposal, as well as their understanding of the need for separate collection and recycling of waste. Environmental education of the younger generation has changed their attitude to the problem of separate waste collection and contributed to the formation of environmental consciousness. Keywords: environmental education, environmental culture, younger generation, municipal solid waste, waste management

In Russia, the problem of garbage is very acute, but only in recent years attempts have been made to solve it. One of the directions is the systematization of the industry and the transfer of responsibility for the removal, sorting and disposal of garbage to regional operators. The compensation mechanism for the costs of such companies involves the establishment of a tariff for municipal services for the treatment of MSW. Setting a tariff that would cover all the costs of regional operators and at the same time be accessible to the public is not an easy task, especially since it should also provide for investment costs for the development of the industry. One of the ways to reduce the tariff is digitalization. The experience of using modern digital solutions shows that they can not only improve the quality of services provided, but also reduce costs, which will have a positive impact on the amount of the tariff for municipal services for the treatment of MSW. The article deals with the problems of tariff regulation of the sphere of solid municipal waste management, for which the method of tariff formation is given, the factors that determine the amount of payment for utility services for solid municipal waste management, as well as the problems of the industry that affect the tariff. The problem of garbage is the most urgent, and the issue of competent financing, including through the establishment of a tariff, will help to overcome the main barriers to its solution.

The possibility of using sorbents from FOPS® filters, spent in the processes of purification of surface wastewater, is shown to intensify the growth of radish plants of the “French breakfast” variety. The ability of these waste sorbents, introduced into soil-ground substrates (SGS) as structure-forming additives enriched with microelements, was found to significantly stimulate the development of the root system with some slight inhibition of shoot growth. In the course of the experiments, the optimal value of the addition of sorbents spent in the processes of cleaning surface runoff (from roads) to the SGS was determined, which provides the greatest increase in the biomass of the root system of plants used as a test culture. It has been established that the accumulation of heavy metals (HMs) in the leaves and roots of a plant test culture increases with an increase in their content in the spent sorbents, but the actual concentrations of HMs in plants do not exceed the standards for their content in robust feed for animal husbandry. An assessment was made of the use of sorbents spent in water purification processes to create soil used in the reclamation of landfills for the placement of solid municipal waste, industrial dumps, road slopes, as well as in the restoration of forest resources and soil remediation.

One of the fundamental economic determinants of sustainable development is the optimal use of limited resources and the use of environmentally friendly-nature, energy, and material-saving technologies, including the extraction and processing of raw materials, the creation of environmentally friendly products, minimization, processing and disposal of waste. In this study, in order to clarify the indicator "ecological potential of the region", it is proposed to consider a number of indica-tors that, according to the authors, have a significant impact on this phenomenon. One of the significant indicators for assessing the ecological potential of the territo-ry is the indicator of the area of landfills for the disposal of solid municipal waste (MSW) in a particular region. The authors hypothesize that the change in the vol-umes of landfills for the disposal of solid municipal waste (MSW) in a particular region depends on the type of development of the territory. As the main defining indicators (factors-arguments) of the development of the region were chosen: the number of manufacturing enterprises, population and gross regional product (GRP) per capita. The authors have developed a regression model to determine the degree of influence of a number of socio-economic indicators on the volumes of landfills for the disposal of MSW. Significant parameters were determined for terri-tories with different types of regional development (extensive type of develop-ment. Using the method of regression analysis, it was found by calculation that for regions of all types of development, the decisive factor that affects the volume of landfills for the disposal of MSW is the population of the territory. With the help of the coefficient of elasticity, the closeness of the relationship of the considered fac-tors-arguments was determined.
