Municipal solid waste (MSW) management in Brazil faces major challenges in order to meet the requirements proposed by the National Solid Waste Policy, which has been in force since 2010 and complicates decision-making, especially in small municipalities. In this context, sustainability indicators are important support tools that help in setting out performance actions for municipal sustainable development. The main objective of this article is to evaluate the four sustainability dimensions (social, environmental, economic, and legal/institutional) using sustainability indicators for MSW management in the Recife Metropolitan Region (RMR) in Northeast Brazil. To do this, the progress of the region was evaluated against the principal goals and guidelines proposed by solid waste plans and by the United Nations Sustainable Development Goals. It was found that some progress has been achieved in recent years, such as the closure of dumps, a reduction of the per capita MSW mass collected, and an increase in the coverage rate for solid household waste collection. However, selective collection and financial autonomy still fall well short of the region’s goals. According to the results of this study, municipalities in the RMR require more environmental education and joint actions involving government, the private sector, and the general population.

Only 16 of the 246 municipalities of Goiás State, Brazil, dispose their municipal solid waste (MSW) in licensed landfills. Therefore, this study proposes the host municipality (HM) of the future shared MSW management facility (MSWMF), serving the Metropolitana de Goiânia (MGyn) microregion. First, the potential areas to construct MSW final disposal facilities (landfills) were identified. Subsequently, using mass point geometry, the HM of the proposed MSWMF for MGyn was defined. The results show that only 19.4% of the area of the studied municipalities is available or subject to approval for landfill construction. The HM will be Aparecida de Goiânia, which will process most of the MSW and send the rejects of treated MSW to the landfill that will be established in the neighboring municipality of Hidrolândia. Additionally, this MSWMF will serve 19 municipalities and will have nine waste transfer stations that will receive waste from 17 municipalities, to minimize MSW transport costs.

Municipal solid waste (MSW) management is internationally recognized for its potential to be both a source and mitigation technology for greenhouse gas (GHG) emissions. Historically, GHG emission estimates have relied upon quantitative knowledge of various MSW components and their carbon contents, information normally presented in waste characterization studies. Aside from errors associated with such studies, existing data do not reflect changes over time or from location to location and are therefore limited in their utility for estimating GHG emissions and mitigation due to proposed projects. This paper presents an alternative approach to estimate GHG emissions and mitigation using the concept of a carbon balance, where key carbon quantities are determined from operational measurements at modern municipal waste combustors (MWCs).

Municipal solid waste management is a huge challenge specially in the developing countries. The first and fundamental step to solve the problem of municipal solid waste management is by waste segregation at source and separate collection of waste, which will help to recover recyclable materials and reduce the amount of waste that needs to be disposed at the dumpsite or landfill site. In Nepal, waste segregation at source is mandated by law but the government is not able to implement it successfully. This paper assesses the willingness of the households to practice waste segregation in future if the government enforces the law and various factors that influences the practice. Data was collected from 401 households which was selected using stratified sampling technique from all the municipal wards, the lowest administrative units in Nepal. The finding shows that about 67% of the respondents are willing to segregate waste in future if the government enforces the law. Logit regression model was employed to identify the factors that influence waste segregation practice. The significant variables found from this study are environmental awareness, waste collection service, willingness to pay, make compost, and segregated waste for a week variables, which are statistically significant at 1% level of significance. Income variable is significant at 5% level of significance and gender variable is significant at 10% level of significance. It is recommended that the concerned stakeholders should educate the households on the importance of waste segregation and consider these traits of households before enforcing the law.

The need for resilience and an agile waste management system in Saudi Arabia is vital to control safely the rapid growth of its municipal solid waste (MSW) with minimal environment toll. Similarly, the domestic energy production in Saudi Arabia is thriving and putting a tremendous pressure on its huge reserves of fossil oil. Waste to energy (WTE) plants provides a golden opportunity for Saudi Arabia; however, both challenges (MSW mitigation and energy production) are usually looked at in isolation. This paper at first explores the potential of expanding the WTE energy production in the eastern province in Saudi Arabia under two scenarios (complete mass burn with and without recycling). Secondly, this study analyzes the effect of 3Rs (reduce, reuse, recycle) practices implementation in a residential camp (11,000 population) to influence the behavior of the camp’s citizens to reduce their average waste (kg/capita). The results of the 3R-WTE framework show a potential may reach 254 Megawatt (MW) of electricity by year 2030. The 3R system implementation in the camp reduced MSW production from 5,625 tons to 3000 tons of household waste every year, which is considered lower than what the surrounding communities to be produced in the same area.

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.

The studies on the solid waste generation and characterization with their relationships with different determinants are limited in Nepal which helps in the implementation of the solid waste management approach.  This study is focused on the quantification of the municipal solid waste (MSW) generation rate and its characterization in the Baglung Municipality, Nepal. Factors affecting MSW generation with perceptions towards the MSW management were also evaluated through household survey. The study was carried out in the month of January 2021 in four wards of urban zone in the municipality. The average waste generation rate in 188 households (HHs), 20 institutions, and 20 commercial sites were 0.43 kg/c/d, 0.83 kg/institute/day and 2.75 kg/commercial site/day, respectively. The largest component, which accounted for about 74% household waste, 75% institutional waste and 52% commercial waste composed of organic waste. The analysis of variance (ANOVA) indicates a significant variation in between MSW generation rate with respect to household size and type of days. Regarding affordability of MSW management, most of the households can be able to afford service fee ranged from US$ 0.5 to 1.0 (55.38%). Most of the households dispose of solid waste in the municipal vehicle. From this study, the residents of the municipality are suggested to prepare compost manure at the source for the minimization of waste volume to be transported and disposed of. Higher production of recyclable MSW depicts there is a possibility of revenue generation and importance of MSW management in community mobilization in the municipality.
