Current practice of waste generation and management in Ukraine has led to an increase in the area of landfills and a loss of the beneficial potential of waste. Today, territorial communities in Ukraine have received enormous new powers within the framework of decentralization, in particular, waste management is now under their jurisdiction. In order to implement the National Waste Management Strategy in Ukraine 2030 and the National Waste Management Plan 2030, communities need to activate the areas of effective disposal of household solid waste (HSW), and for this purpose it is necessary to take into account European norms and standards in this area, as well as share successful Ukrainian and foreign experience. The aim of the study is to analyze a successful case of waste management of a separate community in Ukraine (Illintsi United Territorial Community) as an example for other communities, as well as to develop guidelines for bioenergy recycling of waste in the community under the study with the production of RDF fuel and biogas in order to provide energy resources and improve the condition of the environment. To achieve this goal, there were used the following methods: monographic, deductive, inductive, analysis and synthesis, economic analysis, graphic and tabular, statistical, as well as the case-study method. The conducted research confirmed the growth of waste generation volumes in Ukraine and their limited beneficial use. The developed recommendations on the improvement of the household solid waste management based on the successful case of Illintsi Territorial Community and proposals for organizing the production of RDF fuel and biogas can become a strong basis for the development of communities on the basis of sustainability.

The article examines the environmental performance of a diesel generator that runs on a biofuel mixture. Biofuels are considered to be more environmentally friendly than traditional petroleum products and have become popular alternatives in the field of electricity production. To reduce dependence on petroleum fuels and decrease harmful exhaust-gas emissions from diesel generators, it is suggested to use biodiesel fuel and its mixture with diesel fuel. Various environmental indicators were measured and analyzed in this study, including the emissions of harmful substances, carbon dioxide, nitrogen oxides and particulates. By using biofuels, pollutant emissions are expected to be reduced because biofuels are made from renewable sources such as vegetable oils or biomass. The results of the study show that the use of a biofuel mixture in a diesel generator leads to a significant reduction in the emission of harmful substances compared to the use of traditional petroleum products. A reduction in the emissions of carbon dioxide and nitrogen oxides was found, which contributes to a reduction of the impact on climate change and air pollution. In addition, a decrease in particle emissions was noted, which contributes to the improvement of air quality and people’s health. The goal was achieved by researching the impact of a mixture of diesel and biodiesel fuel on the technical, economic and environmental indicators of an autonomous diesel generator. The regulation of the composition of the fuel mixture ensured the preservation of the power of the generator in all its modes of operation, while reducing the cost of purchasing fuel by 10% and reducing the smokiness of exhaust gas by up to 57%, depending on the mode of operation of the diesel engine.
