Rapid economic development accelerates the generation of municipal solid waste (MSW), and thereby calls for an effective and reliable waste management strategy. In the present work, we systematically investigated the status of MSW management in a mega-city of China (Guangzhou). The data were collected from literatures, government statistics and field sampling work. It can be found that a combination of waste sorting by individual residents and a necessary quantity of sanitation workers is one of the most feasible strategies to achieve a sustainable waste management. With implementation of that integrated strategy, approximately 0.03 million tons of metal, 0.24 million tons of paper, as well as 0.46 million tons of plastics can be recycled/recovered for further processing. A cost reduction of 70 million US$ is achieved in comparison with the un-optimized system due to the sale revenue of recyclable materials and the saving from waste disposal fees. The values of environmental assessment were expressed as environmental load units. The developed scenarios could decrease the environmental cost, namely, 0.66 million US$. Based on the studies, waste sorting is urgently needed in Guangzhou. However, to make the proposed strategy to be more economically feasible, the sorting should be performed individually as well as with public participation. The establishment of a win–win situation for all stakeholders is an effective path for the improvement of the integrated waste management system.

Regulation is a key tool for implementing municipal solid waste (MSW) management strategies and plans. While local authorities in Israel are responsible for the storage, collection, and disposal of MSW, Israel’s Ministry of Environmental Protection (MoEP) is responsible for the formulation and implementation of waste management policies and legislation. For the past 12 years, about 80% of the MSW in Israel has been landfilled and recycling rates have not increased, despite regulations. This paper presents the state of MSW management in Israel in light of the MoEP’s strategic goal of landfilling reduction, the regulations and legislation designed and implemented for achieving this goal, and the ensuing results. Among other things, the results indicate the importance of monitoring and assessing policy and regulations to examine whether regulation is in fact effective and whether it keeps track of its own targets and goals or not. It is also concluded that even when there is an extensive regulation that includes a wide range of laws, economic penalties and financial incentives (such as landfill levy and financing of MSW separation at source arrangements), this does not guarantee proper treatment or even an improvement in waste management. The key to success is first and foremost a suitable infrastructure that will enable achievement of the desired results.

The study of municipal solid waste management was carried out on the example of the city of Uman, the features of the municipal waste collection were considered. One of the promising utilization methods of the municipal waste organic component is proposed — anaerobic fermentation with subsequent composting of the resulting products. Urban population growth, industrialization, urbanization and economic prosperity lead to an increase in municipal solid waste (MSW). The aim of the work was to consider the characteristics of municipal solid waste management using the example of the city of Uman; inspect the features of collecting municipal waste; consider a separate collection system; identify problems and possible solutions. According to the statistics of Uman city council, 73-75 tons of municipal waste per day are delivered to the landfill. The control is carried out on the composition of the waste entering the landfill. Sorting takes place using a sorting line, which was put into operation in October 2016. Removal of municipal solid waste from the residential sector is carried out according to the schedule. The waste from the private sector of the city is removed during the day. Transportation (transport) of municipal waste is carried out by specially equipped vehicles. On the plots of the private residential sector, the collection of municipal waste is carried out by containerless and container methods. The containerless method is used in those areas of private building, where the possibility of the garbage truck's driving and its maneuvering are limited. Analysis of the current state of municipal solid waste management in the city of Uman showed that the main reasons for the increase in the volume of environmental pollution due to municipal solid waste is the lack of a high-quality management system in the field of MSW management, and especially the outdated waste collection and transportation scheme. The state of MSW management does not meet modern requirements. At the landfill, as a result of the introduction of the technology for the production of biogas from municipal solid waste, it is possible to obtain marketable products — biogas and compost. The city can receive income from the use of biogas as an alternative source of energy for heating buildings or from its consuming by the population. For the city of Uman, the volume of biogas formation at the MSW landfill in 2018 would have amounted to 5,441,280 m3, and in 2019 – 5,424,930 m3.Thus, it is possible to obtain significant volumes of biogas for the production of both heat and electricity. As a result of the study, recommendations were developed to improve the system for collecting municipal waste in the city of Uman. One of the promising utilization methods of the municipal waste organic component in the city of Uman is anaerobic fermentation followed by composting of the resulting products.

Municipal Solid waste management in developing countries is a gigantic task and its improper management can lead to severe environmental concerns and immense economic loss. However, many urban local bodies are not fully aware of the existing gaps in infrastructure and MSW management services that should be provided to make the system run efficiently and ensuring compliance to the national rules for waste management.The scale of the problem is huge as the reported annual MSW generation in India is about 58.87 Million tonnes (2016-2018) with an estimated annual increase of about 5%.We all know thatinadequate collection of municipal solid waste results in local and global environmental problems, including air pollution (local health and global climate change) and water pollution (local water bodies and marine litter). The Solid Waste Management Rules of 2016 issued by the Government of India requires source segregation and collection; and identifies specific roles and responsibilities for stakeholders, including waste generators, collectors, and local government. The main objectives of the study were to conduct a gap analysis of the existing municipal waste management system in East Delhi Municipal Corporation (EDMC) area and to assist in ensuring proper implementation of Solid Waste Management Rules 2016.This paper presents the relevant national rules and the current collection practices in East Delhi based on the results of a recent survey of waste management practices. The survey revealed that much of the waste was not segregated, and found that lack of awareness, infrastructure, monitoring, incentives and penalties were the primary reasons for inadequate collection practices in the city. Door-to-door campaigns, television advertisements, and penalties for noncompliance were identified as some of the key measures to improve segregation and collection.The methodology used for the study was a mix of primary and secondary research tools like, transect walks, personal interviews with stakeholders, focus group discussions and literature review; in sample wards of the city to ensure a 90% confidence level. Such a study shall beuseful for other developing countries to help identify priority areas of action and achieve sustainable MSW management.

Over the past decade, generation of municipal solid wastes (MSW) in Malaysia has increased more than 91%. However, MSW management in Malaysia can be considered relatively poor and disorganised. The most preferred of MSW disposal method in Malaysia is through landfilling due to several factors. This method is not sustainable and brings a lot of problems. This paper reviews the characteristics of Malaysian MSW, reports the current practices of MSW management, and provides some suggestions to improve MSW management system in Malaysia.

Mumbai, the largest metropolitan city in India, generated 6,256 tons of waste per day in 2001. It is the responsibility of the Municipal Corporation of Greater Mumbai (MCGM) to provide Municipal Solid Waste (MSW) management services; however, the MCGM is not able to handle the increasing quantity of waste. As a result, waste litters all over the place giving rise to health and environmental problems. Hence, there is a need to involve private sector and community participation in waste management. In this paper, a linear programming model is developed to integrate different options and stakeholders involved in MSW management in Mumbai. Various economic and environmental costs associated with MSW management are taken into consideration while developing the model.

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.

<p>Municipal Solid Waste (MSW) management activities are important tasks of both national and local governments, as they can induce significant impacts on the environment, the economy and the living quality of the population involved.</p><p>The optimal design of a MSW management plan depends greatly on the waste production values and its distribution over the territory, among others. For the optimal design of a MSW system the use of indicators is proposed. Indicators are defined as "the numerical expression, of non-dimensional character, obtained from the fusion of several environmental variables by means of specifically defined weighting criteria". In the scientific literature several proposals about indicators that are focused only on operational aspects of MSW management activities (collection, street cleaning, etc.) are found. Only a decade ago, some indicator groups have begun to emerge in different countries. Such indicators include, in addition to the operational context, social, economic or environmental aspects related to waste management.</p><p>The objective of the work has been to make a choice and proposal of a set of social, economic and environmental indicators related to waste management activities, which will allow the analysis of integrated management systems of solid urban waste, considering all the implications that the operations of production, collection, transport, separation, recovery and disposal of the waste suppose from the economic, social and environmental perspectives.</p>
