Composting as one of the prospective methods of recycling the organic component of municipal solid waste

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.

The article analyzes the features of municipal solid waste management in Tokyo. Special attention is paid to the analysis of trends in the volume of waste in the city of Tokyo over the past decades, as well as the reasons for the constant decline in these volumes. The article deals with the waste management activities of the Clean Authority of Tokyo, discusses the features of treatment of various types of waste, as well as the arrangement of the Tokyo city waste landfill. It was noted that the capital of Japan succeeded in creating an effective system for the disposal and recycling of municipal solid waste that can ensure the environmental safety of the city, as well as integrate waste into the country’s fuel and energy complex. An important feature of Japanese waste management companies is the desire not only to comply with official environmental standards, but also to adhere to their own standards, even more stringent. Based on an analysis of Japanese experience, the authors put forward proposals for optimizing the sphere of waste management in Russia. In particular, attention is drawn to the need to prevent an environmental catastrophe caused by a careless attitude to waste, improve the quality of life of citizens, prevent social unrest associated with environmental pollution, and also involve waste in the generation of electricity and heat. The authors note that as part of the “trash” reform, it is necessary to increase the environmental awareness of citizens, provide citizens with relevant and complete information about the industry, and create stricter environmental standards for waste to energy plants and other enterprises involved in waste management.

Finding solutions to the problem of municipal solid waste management is impossible without involvement in the waste management system of the largest group of wastes – bioorganic waste, which form up to 60% of the municipal solid waste total mass. The aim of the article is to analyze the redistribution of biogenic elements subject to implementation of the Concept of solid municipal waste management by OSENU and subsequent utilization of bioorganic waste flow. Research methods include mass balance and equations of methane generation. The article presents the results of research on the biogenic elements migration in case of complex utilization of bioorganic component of municipal solid waste. The study shows that processing of easy-decomposed organic waste into a gaseous fermentation product and biomineral fertilizer allows full involvement of biogenic elements in natural cycles. The processed solid products present an additional source of organic matter and biogenic elements needed by soil. In the event of humus and nutrients shortage in soil the retrieved-from-waste fertilizer becomes an important secondary resource, containing up to 65% carbon and almost 100% nitrogen, phosphorus and potassium. The rest of carbon is released with biogas and is eventually involved in natural cycles. Burial of such waste results in localization of biogenic elements in a landfill's body and gradual release of carbon with the products of destruction (27% over 50 years). All this data indicate the need for efficient use of such waste resource potential which is possible in case of easy-decomposed organic waste separation at the beginning of the municipal solid waste life cycle. Combustion releases only carbon in the form of carbon dioxide, the rest remains in ash. However, complex utilization of easy-decomposed organic waste ensures complete return of biogenic elements to the environment. Reuse of secondary raw materials in the form of paper and textile waste minimizes involvement in economic turnover of carbon from natural sources.

Aerobic Bioreactors

Landfilling is one of the easiest methods to be applied in the management of municipal solid waste (MSW). In its development, bioreactor landfill methods that have various advantages over conventional landfill emerge. This experiment aims to study the use of bioreactor landfills for the management of organic waste in Jatibarang Landfill, Semarang-Indonesia. There are 4 bioreactor landfills operated: 2 anaerobic bioreactors with leachate recirculation and addition of water, and 2 aerobic bioreactors. Different results are shown from these two types of bioreactor, where aerobic bioreactors reach peak temperatures (55oC each) faster even though anaerobic bioreactors reach higher temperatures (60oC and 61oC respectively). Anaerobic bioreactors reach a higher final pH value than aerobes while the accumulation of nitrogen content from an aerobic bioreactor is 2 times higher than anaerobes.

Analysis of the first results of adoption in RF since January 2019 of the new system of management of municipal solid waste (MSW) and comparison of them with the world experience has been performed, and it has been shown that the principal results supposed to be obtained in the next years, but, the authors believe, that the trends have been chosen correctly and it is possible to hope that the raised problems will be solved successfully. It has been shown that the proposed concept of the life cycles and etageres (whatnots) in the new system of management of MSW in RF does allow to optimize the practical steps, directed to realization of the zero landfilling "No landfills – no waste" principle. By this, due to the separate collecting of MSW, their additional sorting and using the modern technologies complex one can secure environmental safety of population and realize the principles of sustainable cyclic (circular) economy.

Waste management, being one of the most important aspects of urban development, is gaining importance among developing nation like Nepal where rapid population growth, unmanaged urbanization, lack of public awareness and poor management by municipalities have intensified environmental problems in towns in Nepal. In Nepal only six municipalities i.e. Kathmandu, Lalitpur, Pokhara, Dhankuta, Tansen and Ghorahi practice sanitary landfill for waste management and other municipality practices open dumping which has become major cause of environmental and human health hazards (ADB, 2013).Jeetpur Simara Sub-Metropolitan City (JSSMC) is a recently formed sub-metropolitan city. This city has not performed any study on solid waste management till date and lacks data on quantity and composition of municipal solid waste generation that facilitates effective planning of municipal solid waste management. The household survey revealed an average per capita household waste generation rate of 120 g/capita/day. The total Municipal Solid Waste (MSW) generation is estimated about 15 tons/day and 5475 tons/year. The analysis of household waste composition indicated that the highest waste category was organic waste with 80% followed by plastics with 10%, paper and paper products with 6% and inert with 4%. The composition analysis of institutional wastes revealed 41% paper and paper products, 33% plastics, 13% organic wastes and 13% inert. The study found that commercial waste comprised 59% paper and paper products, 21% plastics, 17% organic and 3% inert. In aggregate, MSW is composed of 56% organic waste, 21% paper and paper products, 19% plastics, and 3% inert.
