    Technical and technological aspects of biological reclamation using anthropogenic organic waste in composition with sewage sludge
    (Видавництво Львівської політехніки, 2023-02-28) Tymchuk, Ivan; Lviv Polytechnic National University
    A systematic modern analysis of the state of waste management in the country encourages the search for more rational, efficient and cost-effective ways of processing and recycling solid waste. The inclusion of sewage sludge as a raw material in technologies for processing substrates makes it possible to solve the problems of accumulation and negative environmental impact of this hazardous waste, in addition to the problems of recycling. Promising strategies for the use of sewage sludge in combination with other components for reclamation purposes are considered: the production of substrates by direct mixing without any physical and chemical transformation of the substrate before application for reclamation purposes; composting to obtain reclamation compost; preliminary anaerobic biodegradation with the formation of biogas and subsequent use of digestate for reclamation purposes. The conditions for the application of the strategies, their advantages and disadvantages are analyzed.

    Analysis of the main methods of solid waste management
    (Видавництво Львівської політехніки, 2021-06-01) Storoshchuk, Ulana; Malovanyy, Myroslav; Tymchuk, Ivan; Luchyt, Liubov; Lviv Polytechnic National University
    The world’s growing population and, as a result, higher consumption of goods and services have led to a rapid increase in municipal solid waste. This situation creates serious environmental problems that require clear strategies for managing this waste. Improving the efficiency of recycling to restore quality materials, saving resources and maintaining waste in landfills are among the most pressing problems of our time. The article considers the existing methods of solid waste management in order to select the most optimal waste management system in the context of sustainable development.

    Popularization of the organic component composting of household waste among the population
    (Видавництво Львівської політехніки, 2021-03-01) Korbut, Mariia; Malovanyy, Myroslav; Petrushka, Kateryna; Lutek, Wojciech; Zhytomyr Polytechnic State University; Lviv Polytechnic National University; Maria Curie Sklodowska University
    The study, using a survey, found social attitudes towards the separate collection and problematic issues that may hinder its implementation. It was found that most respondents are not familiar with the possibilities of waste composting at home, and residents of multi-storey buildings generally consider composting at home in the kitchen inexpedient. The paper identified the causes of ignorance of the population on household composting conditions. The paper presents the scientific results of the popularization of composting with microbiological additives at home among the population. The study aimed to develop a practical, effective model for the management of the bioorganic component of municipal solid waste, which minimizes the impact of waste on the environment and maximizes resource potential by organizing composting organic waste at home. Based on the research data, recommendations for the population of Zhytomyr on composting household waste have been developed. They explain in detail the mechanism of composting at home and outline the benefits of such composting. The obtained results are practical, they can be used for explanatory work among the population and the development of recommendations on separate waste collecting and composting of the organic part of household waste in domestic conditions.

    Composting as one of the prospective methods of recycling the organic component of municipal solid waste
    (Видавництво Львівської політехніки, 2020-02-24) Storoshchuk, Ulana; Malovanyy, Myroslav; Tymchuk, Ivan; Lviv Polytechnic National University
    In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40–50 % of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills. Therefore, the choice of promising technologies for the disposal of organic waste is one of the major tasks to ensure environmental safety. One of the effective strategies for dealing with excessive amounts of organic waste and one of the best and most affordable technologies for the waste recycling system is composting.

    Improvement of the composting technology of food component of municipal solid waste
    (Lviv Politechnic Publishing House, 2018-10-26) Krusir, Galyna; Sagdeeva, Olga; Kovalenko, Iryna; Malovanyy, Myroslav; Zakharchuk, Valentina; Odessa National Academy of Food Technologies; Lviv Polytechnic National University; Odessa National Economic University
    The work deals with solving the problem of raising the environmental safety level of the municipal solid waste landfills through the introduction of advanced composting technology of the solid waste food component with the use of mineral and microbiological additives.
