Solid waste management (SWM) is one of the key responsibilities of city administrators and one of the effective proxies for good governance. Effective SWM mitigates adverse health and environmental impacts, conserves resources, and improves the livability of cities. However, unsus-tainable SWM practices, exacerbated by rapid urbanization and financial and institutional limitations , negatively impact public health and environmental sustainability. This review article assesses the human and environmental health impacts of SWM practices in the Global South cities that are the future of global urbanization. The study employs desktop research methodology based on in-depth analysis of secondary data and literature, including official documents and published articles. It finds that the commonplace SWM practices include mixing household and commercial garbage with hazardous waste during storage and handling. While waste storage is largely in old or poorly managed facilities such as storage containers, the transportation system is often deficient and informal. The disposal methods are predominantly via uncontrolled dumping, open-air incinerators, and landfills. The negative impacts of such practices include air and water pollution, land degradation, emissions of methane and hazardous leachate, and climate change. These impacts impose significant environmental and public health costs on residents with marginalized social groups mostly affected. The paper concludes with recommendations for mitigating the public and environmental health risks associated with the existing SWM practices in the Global South.

The increase in population in the city has an impact on the waste produced. Especially with household waste. In addition, the varied consumption patterns of urban communities have the impact of causing waste that will disrupt the quality of life of the community. Therefore, it is necessary to carry out waste management. Waste management is carried out in 5 stages. These stages are 1) Waste collection; 2) Garbage collection; 3) Waste removal; 4) Garbage transportation; 5) Waste processing. The research focus that is the center of attention is waste management from planning to final waste disposal which includes aspects of operational techniques. The type of research used in this study is a type of qualitative research with an exploratory research design. the results of research that has been carried out by the community have known how to process waste in a simple way. However, its application in everyday situations is still rarely done. There are still many people who do not differentiate between organic and inorganic waste. But now urban communities are no longer burning their household waste. The waste from each household has been transported to a final disposal site or final processing place at an independent cost.

Circular economy (CE) has been globally acknowledged as a national sustainable development (SD) strategy to confront resource shortages and environmental contamination challenges. Although public behaviors and lifestyles play an essential role in achieving sustainability, in developing countries, few studies explored the role of public awareness, attitudes, and lifestyles on CE transition. Thus, it is necessary to elicit public opinion to understand their awareness and attitude regarding CE strategy to determine obstacles to CE implementation and approaches of overcoming them. This study thus focuses on understanding public awareness and attitudes to CE transition in Saudi Arabia. Data were collected through a questionnaire survey distributed to 402 residents of the Dammam Metropolitan Area. The results indicated that the respondents had little understanding of the CE concept due to limited awareness of the topic. However, they held an optimistic attitude towards trash separation and classified their trash as "can be sold", "reused", and "exchanged for a new one". Furthermore, the respondents' level of awareness regarding the CE transition is positively related to their level of education. In contrast, the inclination towards resource conservation and pro-environmental behavior positively correlates to the age demographic. This paper thus contributes to the empirical literature on CE transition by exploring the public awareness and attitudes towards its implementation in Saudi Arabia.

Circular Economy (CE) is a growing topic among scholars, industries, and governments, and is aimed at decoupling economic growth and development from the consumption of finite resources. CE incorporates different meanings, from reduce, reuse, and recycle activities, to environmental degradation or resource scarcity, and is supported by specific indicators to attain sustainable development. However, so far, there has been no agreement to measure how effective an industry/product is in making the transition from linear to circular approaches, particularly those that affect society. This research work aims to perform a systematic literature review (n = 60) to analyze and discuss how social aspects have been considered and integrated in CE research so far. Moreover, this review provides an overview of the literature on social impact within the CE, which results in three main outputs: a knowledge map of the CE, an analysis of social aspects within CE, and the theories/frameworks used to evaluate social impact of CE. Finally, this study brings to light how CE implementation can affect society and highlights the importance of social dimension in the domains of CE and a policy-making community, which could help move CE towards a sustainable development.

Waste management is beneficial from an environmental, social and economic perspective. This study aims to investigate the general public and informal garbage collector's perception from social, environmental, and economic aspects. A total of 300 respondents were interviewed (125 households and 125 informal garbage collectors) from seven districts of Faisalabad. The results reported that the majority of the residents blamed themselves for poor management of solid waste which leads to different environmental issues. Lack of awareness among the general public about waste management practices is one of the key factors for environmental issues. Further, solid waste collection by informal garbage collectors would not only improve the social and environmental sustainability but would also serve as a source of income (economic value). Ordinary least square (OLS) method was also used to check the impact of different factors affecting the income level of garbage collectors. Working hours was the only variable which has a significant impact on income. The policy makers should increase the awareness among masses regarding the improvements of the environment by better management. There should also be an awareness program for garbage collectors regarding health hazards by involving NGOs and other volunteers.

The circular economy is a much discussed pathway towards sustainability. While some scholarly work has been carried out on barriers towards a circular economy, there are relatively few academic studies on policies that may accelerate a transition towards a circular economy. Those that focus on policies mostly scrutinize existing policies. The study at hand utilizes data from semi-structured interviews with 47 public and private sector circular economy experts from the European Union to explore expectations regarding circular economy policies, with expectations possibly going beyond existing policies. Expectations identified via this work include more robust standards and norms in production, expansion of circular procurement, tax relief for circular products, liberalization of waste trading and its facilitation through virtual platforms, support for eco-industrial parks, and awareness campaigns. The set of policy recommendations is presented from a life-cycle perspective that is necessary for a transition towards a circular economy. The study aims to contribute to the nascent body of circular economy literature concerning policies and may be of particular interest to practitioners.

Six municipal solid waste management (MSWM) options (A1–A6) in Harare were developed and analyzed for their global warming, acidification, eutrophication and human health impact potentials using life cycle assessment methodology to determine the least impactful option in Harare. Study findings will aid the development of future MSWM systems in Harare. A1 and A2 considered the landfilling and incineration, respectively, of indiscriminately collected MSW with energy recovery and byproduct treatment. Source-separated biodegradables were anaerobically treated with the remaining non-biodegradable fraction being incinerated in A3 and landfilled in A4. A5 and A6 had the same processes as in A3 and A4, respectively, except the inclusion of the recovery of 20% of the recoverable materials. The life cycle stages considered were collection and transportation, materials recovery, anaerobic digestion, landfilling and incineration. A5 emerged as the best option. Materials recovery contributed to impact potential reductions across the four impact categories. Sensitivity analysis revealed that doubling materials recovery and increasing it to 28% under A5 resulted in zero eutrophication and acidification, respectively. Increasing material recovery to 24% and 26% under A6 leads to zero acidification and eutrophication, respectively. Zero global warming and human health impacts under A6 are realised at 6% and 9% materials recovery levels, respectively.

Waste management in urban areas has always been a major concern for municipalities. The gigantic population growth results in massive waste production, leading to a worrying rise in the level of greenhouse gas emissions, a major global issue. The most common techniques for energy recovery from waste are WTE and landfill gas plants. In this research, four different waste management scenarios have been investigated, and the emitted GHGs are analysed using the IPCC guideline for municipal solid waste (MSW) in Tehran. Furthermore, the total cost of each scenario is calculated. Also, effect of various parameters, such as plant usage, methane recovery factor, and MSW heating value, on the emissions is evaluated. The results depict that among all the investigated alternatives, scenario 3 (in which 50% of the waste was burned in WTE plant, 30% landfilled, and 20% recycled) has the least GHG emissions in the target region. For a more thorough analysis, a cost comparison between the scenarios was performed, indicating that landfilling with recovery is the most economical option. Focusing on various technical, economic, and environmental aspects of waste management, this paper provides a comprehensive framework for a combined plan of action in the waste management sector of Iran.

The objective of this study was to develop an aggregate indicator to assess the environmental impact of municipal solid waste management in the small municipalities of the state of São Paulo, Brazil. Additionally, the study aimed at creating a classification of the municipalities considered to identify the best management practices. The study consisted of five phases: Phase 1: Selection of municipalities; Phase 2: Data collection (inputs); Phase 3: Use of the Waste Reduction Model; Phase 4: Analysis of results (outputs) and; Phase 5: Construction of the aggregate indicator and comparison between municipalities to analyze management practices. The results showed that the average waste generation was 223.89 kg (inhabitant⁻¹ year⁻¹), the average carbon dioxide equivalent (CO2e) emissions was 0.166 tons (inhabitant⁻¹ year⁻¹), the average amount of energy savings was 51.37 kWh (inhabitant⁻¹ year⁻¹) and that most municipalities had suitable final waste destinations. After developing the aggregate indicator, which was a geometric mean of the normalized indicators for waste generation, emissions of CO2e, energy consumption and quality of final destination, the municipalities were ranked. Among the ten best-ranked municipalities, six of them disposed of the waste in municipal landfills, and four, in private landfills. Only one municipality is part of a consortium, while seven of them have institutionalized selective collection. One of the critical points for good indicators is the presence of waste pickers. For further improvements in the management of these municipalities, it is suggested that practices involving recycling and the integration of waste pickers with proper technical training are developed and implemented further. It is also recommended fostering greater social inclusion and integrated participation in the management of municipal solid waste. The aggregate indicator developed was regarded as appropriate to assess the environmental impact of municipalities and to classify them, allowing the identification of the best management practices.
