The burning of industrial, agricultural wastes and garbage into ashes is source of significant air pollution due to the following gas components CO, CO2, CH4, C2H4, H2O… etc. Thermodestruction remains one of the effective technologies used in the depollution of these components. This paper is devoted to the modelling of the thermodestruction in a cylindrical incinerator of gas waste produced by the combustion of garbage. Dimensionless transfer’s equations are solved using an implicit numerical scheme, Thomas and Gauss algorithms. We analyze the influence of the mass rate of the inlet smoke on the effectiveness of depollution.

The results of a comprehensive study of the process of thermal destruction of household waste and industrial polymeric materials in a mixture with petroleum feedstock at a pilot coking unit are presented. A mixture containing polyethylene, polypropylene, polystyrene and polyethylene terephthalate was used as household polymeric waste. Industrial waste was represented by a mixture of polyethylene and polypropylene. The qualitative and quantitative composition of the resulting products was investigated. It is shown that the involvement of polymer waste in an amount of up to 8% by weight in the raw material of the coking plant will make it possible to efficiently process polymer waste without changing the technological regime and quality of the products obtained. It has been established that the impurities of inorganic components present in the polymer raw material do not affect the coking process.

Chernihiv is a large city in the north of Ukraine, which has been the center of socio-cultural and political life of Ukrainians since the times of Kyivan Rus’. Today, it is an industrial and cultural center, an important transport hub. In recent years, positive changes have been observed in the socio-economic development of Chernihiv. The article reveals the main features of urban development. Its tasks and main elements are described. The situation related to the state of air pollution, water resources, including in Chernihiv, was analyzed. The main sources of environmental pollution are described. The problem of solid waste management in the city is considered. Urban noise has been described as a factor in air pollution that adversely affects human health. The effect of insolation within the city is characterized, the consequences and requirements for its consideration in the planning of cities, districts or neighborhoods are indicated. The analysis of the aeration regime of the city territory as a factor influencing the comfort of living in the city is carried out. The role of green plantations is determined, which is an important element of the natural environment and improvement of urban space. Three types of comfort in the city (ecological, social and urban) are described and their main features are pointed out. Our vision of a comfortable city, which should be compact, convenient and polycentric, to provide equal access to benefits to different segments of society, is proposed. The industrial complex and the reasons for the decline in the pace and volume of industrial production in some previously leading industries are described. The main enterprises of Chernihiv that imple­ment modern technological solutions are identified. The transport complex of the city and tendencies of its further development are considered. An analysis of health, education, culture and recreation facilities, as well as the situation in the social sphere of Chernihiv. An analysis of a sociological survey among the city’s residents on the improvement problems which concern resi­dents the most has been carried out.

With pandemic progression and the stay-at-home situation, household are producing more dangerous medical waste. Households became the most vulnerable and unprotected sector of coronavirus transmission due to the unconsciousness and lack of guidance of hazardous waste management. Therefore, waste management is a critical concern to public health. This study examines household waste generation and waste management issues in Bangladesh during COVID-19 from March 2020 to August 2021. The study showed that adequate identification, collection, transportation, processing, separation, and disposal are the challenges of safe waste management. Each activity bears a high risk of getting infected because of lack of proper guidance and protection. Moreover, the improper disposal of hazardous waste causes immense soil, water and air pollution that might have negative effects to the human body. Some suggested guidelines to a better COVID-19 household’s waste management are discussed in the context of Bangladesh.

This review highlights the importance of air quality in the African urban development process. We address connections between air pollution and ( a) rapid urbanization, ( b) social problems, ( c) health impacts, ( d) climate change, ( e) policies, and (  f ) new innovations. We acknowledge that air pollution levels in Africa can be extremely high and a serious health threat. The toxic content of the pollution could relate to region-specific sources such as low standards for vehicles and fuels, cooking with solid fuels, and burning household waste. We implore the pursuit of interdisciplinary research to create new approaches with relevant stakeholders. Moreover, successful air pollution research must regard conflicts, tensions, and synergies inherent to development processes in African municipalities, regions, and countries. This includes global relationships regarding climate change, trade, urban planning, and transportation. Incorporating aspects of local political situations (e.g., democracy) can also enhance greater political accountability and awareness about air pollution. Expected final online publication date for the Annual Review of Public Health, Volume 42 is April 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Sepat Village HR Empowerment to Create Superior and Islamic Generations. This research was conducted in order to give birth to generations that were advanced and of quality in general and superior and Islamic in particular. This research is a qualitative research based on research by directly observing the residents of Sepat Village for 40 days. During their stay in Sepat village, researchers found that the younger generation (adolescents) were not visible or only a little bit because the population / number of Sepat Village residents was only ± 1400 people and also the majority of them had migrated out of town. In Sepat Village, there are a lot of parents compared to the young people. That's why all the activities carried out in Sepat Village are already old. Therefore, the authors conducted empowerment research on Sepat Village so that when they graduated from high school or college, they would still be in Sepat Village not to go overseas by utilizing the available potential and human resources and utilizing available technology. It is also hoped that while filling their spare time or taking advantage of the available time, it is hoped that the children can fill the mosque with more useful activities by enlivening the mosque and mosque in Sepat Village. In the field of education, it is hoped that adequate facilities and infrastructure will be provided so that no more Sepat villagers send their children to school outside Sepat Village and provide parental guidance in childcare. Sepat villagers are also able to use household waste to become valuable goods and have a high selling value compared to burning the garbage which can cause air pollution and is not good for health. Therefore, it is hoped that there will be government intervention from both central and village to guide and hold training to continue the program of KPM IAI Bunga Bangsa Cirebon students. Abstrak Pemberdayaan SDM Desa Sepat Untuk Mencetak Generasi Unggul dan  Islami. Penelitian ini dilakukan agar terlahirnya generasi-generasi yang maju dan  berkualitas pada umumnya dan unggul dan Islami secara khusus. Penelitian yang  dilakukan adalah penelitian kualitatif berbasis riset dengan melakukan  pengamatan secara langsung pada warga Desa Sepat sendiri selama 40 hari.   Selama berada di desa Sepat, peneliti menemukan kurang/tidak terlihatnya  generasi muda (remaja) atau hanya sedikit saja dikarenakan populasi/jumlah  warga Desa Sepat hanya ±1400 jiwa dan juga mayoritas banyak yang merantau ke  luar kota. Di Desa Sepat banyak sekali orang tua dibandingkan dengan kawula  muda nya. Makanya semua kegiatan yang dilaksanakan di Desa Sepat penggeraknya sudah sepuh. Oleh sebab itu, penulis melakukan penelitian  pemberdayaan terhadap Desa Sepat agar ketika sudah lulus SMA atau kuliah tetap  berada di Desa Sepat tidak pergi merantau dengan memanfaatkan potensi dan  SDM yang telah tersedia serta memanfaatkan teknologi yang telah tersedia.   Diharapkan juga sambil mengisi waktu luang atau memanfaatkan waktu  yang ada, diharapkan anak-anak dapat mengisi masjid dengan kegiatan yang lebih  bermanfaat dengan meramaikan masjid dan musholla di Desa Sepat. Dalam  bidang pendidikan pun diharapkan tersedianya sarana dan prasarana yang  memadai agar tidak ada lagi warga desa Sepat yang menyekolahkan anaknya di  luar Desa Sepat dan bimbingan orang tua dalam pengasuhan anak. Warga Desa  sepat pun mampu untuk memanfaatkan sampah rumah tangga menjadi  barangyang berharga dan nilai jual tinggi dibandingkan membakar sampah  tersebutyang dapat menimbulkan polusi udara dan tidak baik juga untuk  kesehatan. Oleh sebab itu, diharapkan adanya campur tangan pemerintah baik dari  pusat maupun desa untuk membimbingdan mengadakan pelatihan guna  melanjutkan program dari mahasiswa KPM IAI Bunga Bangsa Cirebon

In connection with the development of urbanization, the protection of cities and the environment, issues of restoring the ecological balance become an urgent issue. The scale and intensity of product development in Azerbaijan enhance the anthropogenic impact on the nature of the regions. Such an effect is manifested in the pollution of soils with industrial, household waste, chemical fertilizers, the burning of hydrocarbons, the emission of harmful substances in the water and vehicles into the environment. Like in the whole world and in Azerbaijan, such negative processes are no exception. In this regard, the environmental problems of cities and urban agglomerations around the world are in the focus of attention of specialists and scientists. The presented article considers environmental and geographic problems that arose as a result of air emissions in 8 cities of Azerbaijan. The historical properties of studying atmospheric pollution in cities are analyzed, ecogeographic methods for studying atmospheric pollution of cities are identified, environmental pollutants of large cities and the ecogeographic properties of their influence are considered. The ecological properties of the geographical condition, meteorological climatic conditions in air pollution, aerospace research in the study of atmospheric pollution in large cities and the effect of pollution on the health of the population of large cities are studied. The transport system of cities, their geography, and the effect of emissions of harmful, poisonous substances into the atmosphere by vehicles on public health were also noted. Based on the methods for predicting atmospheric air pollution in large cities and the non-linear regression technique, a mathematical model of ecogeographic forecasting of air pollution is applied. Comprehensive indicators and the level of air pollution in unfavorable conditions for urban agglomerations are determined.

The work discusses the perception and assessment of environmental factors of the quality of life in No-vosibirsk by its residents. In the study the authors identified the subjective attitude of respondents to the environmental situation in the city. The envi-ronmental threat is seen by respondents as a danger of medium importance against the background of dangers such as unemployment. The respondents were most worried about the dustiness of Novosi-birsk, air pollution, and the pollution of the city. From the answers of the respondents to the ques-tions devoted to assessing different aspects of the activity of the housing and communal services of Novosibirsk, it follows that to the greatest extent the respondents expressed satisfaction with the water supply of their houses, cleaning of the local area and the removal of household waste. The wishes of the respondents to improve the quality of life in their area of residence are more specific than the wishes that apply to the whole city. It turned out that re-spondents were more concerned about the stand-ard, rather than the quality of their lives. In general, respondents are mostly satisfied with the state of the environment in Novosibirsk.
