Introduction. Every year in Ukraine about 40-50 million tons are dumped in landfills. household waste, of which only no more than 2 million tons are processed and disposed of. To date, more than 15 billion tons of waste have been accumulated in landfills. Insufficient number of official, registered and equipped landfills, lack of modern landfills, as well as insufficient level of waste disposal are the reasons for the emergence of so-called unauthorized landfills, often located within the city. Problem Statement. To date, the processes of utilization of fine fractions of waste, which include the decomposition products of organic waste, remain the least developed. In various methods of waste disposal there are problems when working with large volumes of dispersed waste at almost all stages of their processing. Thus, to increase the efficiency of waste disposal, it is necessary to increase the relative size of the material being processed. This can be done at the stage of preliminary preparation of raw materials. The right choice of pre-treatment method will reduce the negative impact on humans and the environment of harmful elements contained in household waste, as well as increase the efficiency of their disposal Purpose. Carrying out of theoretical and experimental researches of ways of granulation of dispersed fraction and products of disintegration of solid household waste as a stage of their preliminary preparation for utilization. Substantiation on the basis of the received parameters of technology of mechanical processing of waste by various methods of granulation and preparation of the recommendation to a choice of a way of preliminary preparation of dispersed waste for their effective utilization by thermolysis and energy recovery. Carrying out the analysis of ecological danger of formation of dioxins in the course of processing of waste, and also giving practical recommendations concerning their minimization. Materials and methods. As the main stage of preliminary preparation of the dispersed fraction of waste for further processing, three methods of compounding the decomposition products of household waste were considered. Two methods that do not directly affect the particle density - fluidization and granulation in a fluidized bed, as well as pressing. The process of encapsulation of fine waste was studied in an open-type plate granulator; fluidized bed granulation was performed in a laboratory unit-granulator of periodic action with a fluidized bed; compression of dispersed waste was carried out using a screw stamp press with a detachable matrix. Results. Peculiarities of granulation of the dispersed fraction of household waste by different methods have been established. Improving adjustments have been made to the existing developed scheme of thermolysis and energy recovery on the basis of the conducted methods of preliminary preparation of dispersed waste. The economic effect of the introduction of the method of thermolysis and energy recovery of waste into production on the territory of Ukraine, which is planned to be 8 million USD / year, was also calculated. Conclusions. The research results presented in the paper will facilitate the choice of method and means of preliminary preparation of waste for various existing types of their utilization. An experimental method of thermolysis-energy recovery is proposed as an effective method of waste utilization. Adjustments in the existing scheme of TERW on the basis of the conducted researches are planned to essentially increase efficiency of such processing. The ecological danger of formation and emissions of dioxins in the process of thermal processing of waste is considered, as well as practical recommendations for their minimization are given. Key words: solid household waste, decomposition, granulation, thermolysis recovery, dioxins

AbstractMany cities in developing countries lack adequate drainage and waste management infrastructure. Consequently, city residents face economic and health impacts from flooding and waterlogging, which are aggravated by solid waste infiltrating and blocking drains. City governments have recourse to two strategies to address these problems: a) ‘hard’ infrastructure-related interventions through investment in the expansion of drainage and waste transportation networks; and/or, b) ‘soft’, low-cost behavioural interventions that encourage city residents to change waste disposal practices. This research examines whether behavioural interventions, such as information and awareness raising alongside provision of inexpensive street waste bins, can improve waste management in the city. We undertook a cluster randomized controlled trial study in Bharatpur, Nepal, where one group of households was treated with a soft, low-cost intervention (information and street waste bins) while the control group of households did not receive the intervention. We econometrically compared baseline indicators – perceived neighbourhood cleanliness, household waste disposal methods, and at-source waste segregation – from a pre-intervention survey with data from two rounds of post-intervention surveys. Results from analysing household panel data indicate that the intervention increased neighbourhood cleanliness and motivated the treated households to dispose their waste properly through waste collectors. The intervention, however, did not increase household waste segregation at source, which is possibly because of municipal waste collectors mixing segregated and non-segregated waste during collection. At-source segregation, a pre-requisite for efficiently managing municipal solid waste, may improve if municipalities arrange to collect and manage degradable and non-degradable waste separately.

The article analyzes the environmental, legal and administrative aspects of medical waste disposal during the Covid-19 pandemic in Ukraine. The substantiation of priorities of improvement of ecological-legal and administrative-legal maintenance of procedure of utilization of medical waste during the Covid-19 pandemic is presented. It is emphasized that the state takes a number of measures to reduce mortality from this disease, while increasing the negative impact on the environment of medical waste generated as a result of vaccination, disease prevention, diagnosis, inpatient treatment of this disease. Their uncontrolled disposal together with household waste has a negative impact on the environment, polluting land and water resources, is a dangerous source of infection. It is established that the environmental, legal and administrative support of the medical waste disposal procedure during the Covid-19 pandemic is related to the formation of the regulatory framework for medical waste management, including collection, transportation, storage, sorting, processing (processing), disposal, removal, and effective activities of public administration and law enforcement agencies to monitor this process. The facts of successful counteraction of such bodies to illegal activity concerning transportation, storage, utilization of medical waste are emphasized. It was found that many problems in this area are due to insufficient funding of the medical sector. The need to implement effective administrative and legal measures, especially control and supervision of economic entities for the disposal of medical waste, to regulate in detail the procedure for medical waste disposal, to devote an important place to this issue in the National Environmental Action Plan until 2025, approved by the order of the Cabinet of Ministers of April 21, 2021 № 443-r and to strengthen the administrative liability of licensed organizations for the provision of medical services for violations in this area. It is recognized that in such conditions it is extremely important to adapt EU legislation on medical waste disposal to Ukrainian realities.

Waste indiscriminate disposal is recognized as an important cause of environmental pollution and is associated with health problems. Safe management and disposal of household waste are an important problem to the capital city of Guinea (Conakry). The objective of this study was to identify socioeconomic and demographic factors associated with practice, knowledge, and safety behavior of family members regarding household waste management and to produce a remedial action plan. I found that no education background, income, and female individuals were independently associated with indiscriminate waste disposal. Unplanned residential area was an additional factor associated with indiscriminate waste disposal. I also found that the community residents had poor knowledge and unsafe behavior in relation to waste management. The promotion of environmental information and public education and implementation of community action programs on disease prevention and health promotion will enhance environmental friendliness and safety of the community.
