All over the world, a huge amount of waste is generated every minute. The organization of an effective waste management system is very topical. The economic efficiency and costs of the users of the system depend on a properly organized system of accumulation, transportation, processing or disposal. The article discusses the process of working with waste in the cities of Russia. The technique and methods of working with waste in large cities at the first stage of removal are described. The problem of optimization of the territorial scheme for the disposal of solid municipal waste has been formulated. The technological process of operation of the first leg garbage truck on the route is described and considered. The criteria and factors influencing the choice of the optimal route are formulated. The necessary initial data for calculating the optimal scheme of waste gravitation are described. The function of total route costs has been built.

Electronic waste (e-waste) has become one of the fastest-growing waste streams in the world. However, only 17.4% of it can be collected and recycled in 2019. This study aims to formulate strategies to improve the supply chain of e-waste management in Indonesia. Methods used to develop strategies in this study are the Decision-Making Trial and Evaluation Laboratory (DEMATEL), the Analytical Network Process (ANP), Strength–Weaknesses–Opportunities–Threats (SWOT), and the Quantitative Strategic Planning Matrix (QSPM). The results show that infrastructure criteria have the largest weight, that is 0.267, followed by a social environment with 0.261, regulation with 0.244, stakeholder with 0.122, and economy with 0.054. The top priority of the selected strategies is to improve public education (ST1) and provide socialization of regulations and sanctions to the public (ST2).

In the modern world, environmental issues are quite acute. Global environmental problems are also relevant for Russia today. It should be recognized that our country is one of the most polluted countries in the world, which negatively affects the quality of life and health of the population. The emergence of environmental problems is associated with the ever-growing man-made impact on the natural environment. Currently, about 55–60 million tons of solid municipal waste is generated in Russia every year, 90 % of which is sent to landfills and unauthorized landfills. The recycling rate in Russia is no more than 10 %, while in the European Union countries up to 100 % of household waste is processed. Europe has been implementing a targeted environmental policy for working with solid municipal waste for many years. Back in December 2005, the European Commission published a report on the development of a strategy for the prevention of waste generation and recycling. its goal is to reduce the negative impact on the environment associated with the disposal of household waste. Waste policies and targets established at the European Union level include minimum requirements for the management of certain types of waste. The subject of research in the article is the system of solid municipal waste management, waste management strategies. The purpose of the article is to study the current state of the waste management system in the world and in Russia, analyze the features and prospects, and develop recommendations based on foreign experience. Research methodology: comparative and comparative analyses. The article presents analytical data that characterize the current situation, analyzes the forecast values of solid municipal waste generation and disposal in different regions of the world. A detailed analysis of the situation in Russia is given, conclusions on the current situation with regard to waste are given, and recommendations are made. Based on the analysis of statistical data that characterize the state of the solid municipal waste management system in the world and in Russia, conclusions were made about the problems of its development. One of the main reasons is the lack of attention on the part of state bodies, as well as the lack of funding for the implementation of state programs and the inefficient use of allocated funds. The analysis of foreign experience in waste management allowed us to develop recommendations for the application of management strategies. This article is part of the author's research in the field of choosing optimal strategies for managing the development of a "Smart city", including strategies for managing the disposal of solid municipal waste of the housing and communal complex. the author has analyzed and collected interesting material on this topical issue, and plans to publish a monograph.

The problem of urban solid waste management is regarded as one of the most important environmental issues, especially in developing countries. Municipalities all around the world are dealing with increasing levels of solid garbage and need to devise effective strategies to tackle the problem. It is critical to understand the amount of garbage created and the makeup of the waste stream in order to develop successful waste management in any location. Many research have established that the amount of waste generated is proportional to the population. There are several other factors which affect the amount and composition of waste. The enormous increase in solid waste generation particularly in large cities will have significant impact in terms of the land required for waste disposal

Global environmental problems all over the world are extremely acute, they are associated with the constantly growing man-made impact of man on the environment. Extraction and processing of resources affect production processes, the natural environment, and public health. This is especially true of waste generated in the production and consumption process, which cannot be used for further use due to technical or economic reasons. Despite the fact that municipal solid waste (MSW) constitutes less than 1 % of the total amount of industrial and domestic waste generated, it is the most annoying factor for the population, especially in large cities and adjacent areas. The basis of the strategy is the separate collection of waste by the population, the “sorting depth” depends on the current policy in this area: from 4–5 types of MSW in a number of European countries, to 40 in some regions of Japan. The subject of the research is the solid waste management system. The purpose of the article is to study the waste management system in the world and in Russia, analyze the current situation and choose a management strategy to solve the problem of waste disposal. Research methodology: financial and economic analysis. The article presents analytical data on the formation and disposal of electronic and plastic MSW, which have a clear tendency to significant growth, leading to an increase in incineration and disposal. Global problems are also relevant for Russia, where the level of MSW processing is not high and so far there are about ten incineration plants (WIPs) with low productivity. For comparison, the number of incinerators: in Switzerland – 29, in Japan – 1900, in Sweden – 21, in Denmark – 32, the total number of inhabitants in these countries is less than the population of Russia. New factories are expensive both during construction and operation. The article provides an assessment of the economic consequences of switching to MSW processing by incineration at an incineration plant, provides a financial and economic model of the project. Analysis of foreign experience made it possible to understand the causes of the problems and develop recommendations. This article is part of the author’s research in the field of choosing optimal strategies for managing the disposal of solid municipal waste, based on the collected material, it is planned to publish a monograph.

A new coronavirus pandemic is raging all over the world, especially in densely populated areas. Unlike most countries, more than half of the territory of Russia is not used by humans — which means that it is possible to settle large cities to avoid crowding people on a small area. The authors of the article consider wind power, namely vortex wind power plants, as a new source of energy that can be quickly and with less harm built in rural areas. The article also discusses the possibilities of an alternative Autonomous non-volatile installation "Air spring" for obtaining fresh water from atmospheric air.

This chapter examines evidence principally from the US that the Great Influenza provoked profiteering by landlords, undertakers, vendors of fruit, pharmacists, and doctors, but shows that such complaints were rare and confined mostly to large cities on the East Coast. It then investigates anti-social advice and repressive decrees on the part of municipalities, backed by advice from the US Surgeon General and prominent physicians attacking ‘spitters, coughers, and sneezers’, which included state and municipal ordinances against kissing and even ‘big talkers’. It then surveys legislation on compulsory and recommended mask wearing. Yet this chapter finds no protest or collective violence against the diseased victims or any other ‘others’ suspected of disseminating the virus. Despite physicians’ and lawmakers’ encouragement of anti-social behaviour, mass volunteerism and abnegation instead unfolded to an extent never before witnessed in the world history of disease.

Universities around the world have faced a new pandemic, forcing the closure of campuses that are now conducting educational activities on online platforms. The paper presents a survey about students behavior and attitudes towards online education in the pandemic period from the Technical University of Cluj Napoca, Romania. A group of 300 students participated. The questionnaire was structured in four parts to determine student’s individual characteristics, student’s needs, students’ knowledge in using virtual platforms and students’ quality preferences for online education. The students said that online education in a pandemic situation is beneficial for 78% of them. A total of 41.7% percent of students appreciated the teachers’ teaching skills and the quality of online courses since the beginning of the pandemic, and 18.7% percent of the students appreciated the additional online materials for study to support their education. However, students found online education stressful, but preferred online assessment for evaluation. This pandemic has led to the new stage of Education 4.0, online education, and the need to harmonize methods of education with the requirements of new generations.
