The problem of efficient management of municipal solid waste (MSW) flows remains one of the most urgent environmental and socio-economic problems of the Ukrainian regions. Ineffective MSW management leads to a significant negative impact on the abiogenic and biogenic components of the environment, as well as on the Ukrainian regions' citizens' state of health. Each individual region has its specific situation that should be taken into consideration for the development and implementation of regional plans for MSW management. Usually most of these regional plans are limited by such factors as determination of the volume of generated MSW, inventory of landfills, calculation of the required number of containers and technical means, justified expediency of MSW sorting stations placement, new MSW landfills construction etc. However, little attention is paid to introduction of innovative approaches for development of an effective MSW management system. There is no systematic approach to solving the MSW-related problem and all efforts aim at eliminating the consequences, rather than changing the ultimate cause. The aim of the research is to assess the prerequisites for the formation and implementation of a MSW management plan in Odesa Region from a systematic approach perspective. The methodological basis of the research includes analysis of the existing regulatory and legislative framework in the area of regional MSW management. The work is based on the relevant published data, materials of the Draft Regional Waste Management Plan in Odesa Region by 2030, as well as the results of our own research activities. The regional MSW management plan can be implemented at the following main areas: introduction of a MSW management system in big cities (separation of easily-decomposed organic fraction and hazardous waste, creation of recycling centre and stations etc.); landfill activities (construction of waste sorting plant, construction of biochemical processing/composting facilities, biogas production); development of logistics services (transition to small garbage trucks: separate vehicles for individual MSW components or vehicles with separate sections without waste precompaction); training of qualified personnel, educational work with great masses of population. Consideration of these prerequisites during the formation and implementation of a MSW management plan in Odesa Region will help to increase the environmental safety of the population, reduce the negative impact on the environment through improvement and modernization of the existing MSW management system and achievement of the final "zero waste" condition after conversion of the maximum waste amount into liquid secondary raw materials, alternative energy source and environmentally friendly organic mineral fertilizer. The implementation of the conceptual and theoretical foundations for formation of an optimized MSW management system will contribute to the achievement of the goals of sustainable development set by Odesa Region.

Solid Waste Management System

Currently, the problem of organizing a municipal solid waste management system (MSW) has become more acute in Russian regions and all over the world. Various environmental and economic problems, as well as problems related to public health negatively affect many aspects of the development of modern society. Therefore, the careful organization of the management of the MSW management system is of great social importance and needs constant improvement. In this paper, we look at the MSW management system from the point of various scientific approaches, namely, structural analysis methods, geoinformation technology methods, reliability theory for complex technical systems, evergetics, graph theory and fuzzy logic methods, including the apparatus of linguistic variables. The purpose of the work is to show the possibility of application and systematic combination of the above scientific methods that have proven themselves well in their fields to a new area of the MSW management systems. However, just application of these approaches is impossible without their further adaptation and systematization from the point of view of existing approaches to the management of similar systems. As part of this study, elements of the MSW management system were identified and a topological model of the system was developed. Structural-logical models of reliability at various levels of abstraction were also built.

The rapid increase in waste volume leads to numerous and widespread impacts on sustainable development including social, economic and environmental dimensions. This study applied Wasteaware benchmarking, which is a set of international indicators, to evaluate the effectiveness and sustainability of municipal solid waste management in Bangkok. The indicators allowidentification of strengths and weaknesses of the urban waste management system, providing evidence-based guidance for further improvement. Structured questionnaires were developed based on the indicators and its manual for in-depth interviews with key stakeholders from Bangkok Metropolitan Administration (BMA). The data were analyzed using wasteaware datasheet under Microsoft Excel with score coding, generating a clear and detailed overview of the performance of Bangkok’s municipal solid waste management system (MSW). The overall assessment demonstrated that all waste collected is disposed through official treatment facilities. However, the system’s effectiveness is constrained by ineffective enforcement of relevant regulations. Moreover, waste collection services were found to be not fully efficient. In terms of financing sustainability, improvements are needed to reduce disposal costs. Even if BMA prioritizes waste collection and disposal, it is equally important to promote the 3Rs and fully implement source separation to reduce waste volumes at source. In this regard BMA’s efforts to waste volume reduction targets have met with limited success, and the volume of waste generated in Bangkok continues to rise each year. To enhance the sustainability of MSW management, the outcome of this study could be used to support decision-making and further development, as well as provide inputs for future research.

The Past

The state of the waste management system in St. Petersburg and Finland over the past 25 years is considered. It is shown that over the years, the system of municipal solid waste (MSW) management in St. Petersburg has not fundamentally changed. The bulk of waste - 88% is taken to landfills, and 12% is processed into compost. In Finland, over the years, the MSW management system has changed significantly: the amount of waste disposed of at the landfill has decreased by 46 times, the amount of waste incinerated at incinerators has increased by 7 times; the amount of waste selected for secondary raw materials increased by 1.5 times. An assessment of environmental damage to municipal solid waste management systems showed that over the past 25 years, specific environmental damage for St. Petersburg increased 2.22 times, and for Finland decreased 18.07 times.

The Status

Major cities in transitional and developing countries are facing the ever-growing challenge of managing solid waste in a sustainable manner. While a variety of treatments exist for solid waste, cities are in need of a sustainable integrated municipal solid waste management (MSWM) system. Such a system is meant to assist them in selecting and investing in an appropriate combination of treatments for the waste they generate, depending on the composition and quantity of this waste. This study presents a systems analysis of the MSWM in Cairo. A constrained non-linear mathematical model is developed to represent an underlying model of a MSWM system, with six waste material flows (cardboard and paper, plastics, metals, glass, organic material, and others). The developed model depicts combinations of five treatment alternatives (composting, anaerobic digestion, mechanical biological treatment, incineration, and landfilling). The treatment methods and their capacity are determined by the model, indicating possible optimal design solutions and recommendations. Starting with an evaluation of the status quo of the MSWM system in Cairo, the paper proposes a staged strategy, involving investigating improvements to the current mixed-waste management system, then exploring the possibility of introducing at-source waste sorting. The environmental and economic implications of different scenarios are analyzed and compared. A material flow analysis, including input data uncertainties, is also conducted by applying substance flow analysis. This analysis shows the difference between the status quo and the proposed improved solutions for diverting waste from landfills and, thus, decreasing carbon dioxide emissions.

Because the consumption of materials is generally higher than their recovery rate, improving municipal solid waste (MSW) management is fundamental for increasing the efficiency of natural resource use and consumption in urban areas. More broadly, the characteristics of a MSW management system influence the end-of-life (EOL) impacts of goods consumed by households. We aim to indicate the extent to which greenhouse gas emissions from a MSW management system can be reduced by increasing waste paper recycling. We also address the stakeholders’ contribution for driving transition towards an improved scenario. Life cycle assessment (LCA) addresses the EOL impacts of the paper industry, driven by the characteristics of MSW management in Florianópolis, Brazil, by varying the level of stakeholders’ commitment through different recycling scenarios. The results show that 41% of the climate change impacts from waste paper management could be reduced when increasing the waste paper recycling rates and reducing waste paper landfilling. To achieve such emissions reduction, the industry contribution to the MSW management system would have to increase from 17% in the business-as-usual scenario to 74% in the target scenario. We were able to measure the differences in stakeholders’ contribution by modelling the MSW management system processes that are under the industry’s responsibility separately from the processes that are under the government’s responsibility, based on the Brazilian legal framework. The conclusions indicate that LCA can be used to support policy directions on reducing the impacts of MSW management by increasing resource recovery towards a circular economy.
