Abstract Household solid waste management (HSWM) practices are a critical aspect of municipal solid waste management (MSWM) systems. Despite efforts to implement source separation and recycling at the household level in developing countries, negative practices such as illegal dumping and backyard burning remain ubiquitous, particularly in rapidly urbanizing cities. Source separation and recycling behaviors have been rarely studied in such cities. Moreover, studies on illegal dumping and backyard burning using robust tools and frameworks are practically non-existent. This study aims to (a) estimate the prevalence of “negative” and “positive” behaviors for different HSWM practices, and (b) identify their observable and non-observable influencing factors. The focus is Santa Cruz, a rapidly urbanizing city of Bolivia. Household surveys (n=305) are used to establish the connections between latent constructs (e.g. awareness, satisfaction), and observable variables (e.g. location, socio-demographic characteristics) with each behavior. This is achieved through the combination of exploratory factor analysis to validate the constructs to be included in the analysis, and structural equation modeling to identify the most influential factors. Two causal models are developed, one for the positive behaviors (i.e. source separation, recyclables donation, recyclables selling, and use of drop-off facilities), and the other for the negative behaviors (i.e. illegal dumping and backyard burning). Results indicate that, satisfaction with the MSWM service has a negative and significant influence on the prevalence of illegal dumping and backyard burning behaviors, while the remoteness of the household (i.e. distance to the city center) has a positive significant effect on the prevalence of these behaviors. Source separation and recyclable donation are influenced positively by latent constructs such as attitudes, knowledge, and awareness. For recyclables selling and use of drop-off stations, income and location are the most relevant factors, although with smaller effects.

Resumo: O consumo, aliado à industrialização, a cada ano produz muitos tipos de novos produtos e embalagens. Junto a isso, a distribuição e a logística vêm alcançando locais cada vez mais remotos, fazendo com que áreas rurais disponham dos mesmos produtos existentes nas áreas urbanas. A preocupação com esse avanço é a disposição final desse material, ou o gerenciamento dos resíduos sólidos domésticos nessas áreas. Os custos desse processo podem trazer obstáculos à sua realização. Dessa forma, esta pesquisa objetiva demonstrar algumas dificuldades sobre a gestão integrada de resíduos sólidos, principalmente pela análise da área rural de Santa Cruz do Sul. Identificou-se que o resíduo doméstico rural transportado pelos caminhões não era pesado, apenas registrada a entrada dos caminhões, dificultando o entendimento da eficiência desse atendimento. Assim, uma discrepância pode passar despercebida pelos gestores, pois o município de Santa Cruz do Sul/RS não possui uma área rural muito extensa. Para poder observar esse processo, foram rastreados dados entre os anos de 2007 à 2015, através de pesquisas bibliográficas e documentais. Foi possível verificar que o número de cargas das áreas rurais vem aumentado, sem alteração na população rural como também sem aumento de produção das embalagens. Além disso, os valores cobrados por esse transporte a cada ano se tornam mais caros. Portanto, para ter uma gestão transparente e políticas públicas eficientes, faz-se necessário disponibilizar e analisar os dados e valores sobre a produção de resíduos sólidos de forma clara e objetiva, com a elaboração de um processo que seja eficaz enquanto medida socioambiental.Palavras-chave: Gestão de Resíduos.

Together, the distribution and the logistics are reaching places increasingly remote, so that the rural areas can have the same products that the urban areas do. The concern on this advance is the final disposal of this material or the domestic solid waste management in these areas. The costs of this process can bring some difficulties for the realization of this type of collection. This research was done to demonstrate some difficulties about the integrated solid waste management, mainly through the analysis of the rural area of Santa Cruz do Sul. It was identified that the rural domestic waste transported by trucks was not weighed, only registered the entry of trucks, making it difficult to understand the efficiency of this attendance. Therefore, this discrepancy can go unnoticed by the managers, because the city of Santa Cruz do Sul/RS does not have a very large rural area. To observe these procedures, it tracked data between the years of 2007 to 2015, through bibliographical and documental research. Thus, it was possible to verify that the number of loads from the rural areas is increasing, without an alteration on the rural population, but also without increasing packaging production. In addition, the costs charged for this transportation become more expensive each year. Therefore, in order to have a transparent management and efficient public politics, it is necessary to make available and analyze the data and values about the solid waste production in a clear and objective way, with the elaboration of a process that is effective as a socio-environmental measure.Keywords: Waste Management.

The management of municipal solid waste (MSW) in China is facing urgent problems with rapid industrialization and urbanization. This article focused on the status of Hangzhou, capital city of Zhejiang province, China. The regulations, policies, implementation, barriers and solutions about source separation, separate collection, clean & direct transportation, treatment and disposal were introduced. Source separation, separate collection and clean & direct transportation were seriously carried out from 2010. MSW was classified into four kinds, such as kitchen waste, hazardous waste, recyclable waste and other waste. Four kinds of wastes were collected, transported, treated and disposed, respectively. At the same time, a questionnaire survey was conducted in 2011 on 200 households in Xiasha and Gongshu Districts in Hangzhou. The results indicate that many citizens cannot effectively and correctly separated different kinds of solid wastes. Kitchen waste was directly disposed in landfill, because there is no composting plant in Hangzhou City. The collection of recoverable waste and hazardous waste was not in control of municipal solid waste management (MSWM) system. In order to optimize MSWM system in Hangzhou, the government and the citizen must make efforts in source separation, comprehensive treatment system, effective regulations and policies.

Municipal solid waste management (MWSM) systems have been evolving across most of the developing world. However, despite decades of refinement, they are still underperforming in many cities, leading to negative sustainability impacts in rapidly urbanizing cities of the global South. Despite similarities in the observed transitions between developed and developing countries, there are important differences in their characteristics and underlying drivers. This study aims to unravel the sustainability transitions of the MSWM systems in the two major cities of Bolivia, La Paz and Santa Cruz de la Sierra, illustrating the role of various actors, and specifically local governments. This is achieved through the analysis of secondary data and expert interviews with stakeholders involved in different aspects of the MSWM system at the national and local level. We identify three partially overlapping sustainability transitions in the two cities, namely “Collection and centralized disposal”, “Environmentally controlled disposal”, and “Integrated solid waste management”. However, timelines, speed and elements of these transitions are somewhat different between cities, largely due to their inherent characteristics, institutions and stakeholder dynamics. Many technological, socioeconomic, and institutional factors converge to facilitate and hinder these transitions, including interactions of government and private sector actors, and the country’s broader political context.

AbstractPoor solid waste-management systems in cities in developing countries make them vulnerable to climate-induced risks. It has been pointed out in the literature that the waste management process needs to be holistic and inclusive from waste generation to disposal in order to make it efficient and sustainable. While women in their day-to-day activities at home play a critical role in waste management, they are often excluded in the public waste-management systems which are mainly managed by men. This research used women-centric approaches for motivatingcitizens using social and moral persuasion, economic incentives and social recognition to participate in municipal solid waste management. The findings indicate that the awareness campaign using motivational approaches eventually worked and that the women-centric approaches used are important for promoting home-based waste segregation at source. The study also revealed that a simple payment mechanism for waste disposal services at the household level is not enough to convert littered cities into clean cities. A women-centric approach also contributes to developing community-based solutions to adapt to climate-induced flooding and makes a city more resilient, addressing sustainable development goals.

The present study conducted a Life Cycle Assessment evaluation of the Solid Waste Management System in Santa Cruz do Sul – RS, in order to provide background information and therefore support decision-making for future waste management scenarios. The software package named as Integrated Waste Management – 2, Version 2.5., was used to perform the LCA, where all inputs and waste management system outputs were identified and quantified. The conversion of the results from Life Cycle Inventory to Life Cycle Assessment in environmental impacts was carried out based on impact characterization factors from RECIPE 2008 version 1.08. The impact categories studied were: Photochemical Oxidant Formation Potential, Global Warming Potential, Acidification Potential, Eutrophication Potential, Depletion of the Ozone Layer Potential and Particulate Matter Formation Potential in addition to the Use of Energy and Final Solid Waste. The current waste management scenario has been simulated as baseline, considering three additional scenarios, which included raising the number of households served by selective collection, improvement of recycling recovery efficiency in the sorting stage and the introduction of the biological treatment stage into the system by composting the organic matter. The results showed that the current scenario is the most impacting, for global warming, with a total of 12,102,122.85 kg of emissions per year, whereas scenario 04 showed to represent the lowest contribution rates to environmental impacts in carbon footprint perspective (5,946,702.47 kg of emissions per year). The final disposal stage in landfills had also contributed significantly to environmental impact rates, followed by the waste collection scenario. The proposed changes, suggested by alternative scenarios, had demonstrate considerable environmental savings, hereby justifying the importance of implementing these strategies in waste management.  Keywords: Life Cycle Assessment.

Source separation plays a pivotal role in sustainable and integrated Municipal Solid Waste Management (MSWM) and in achieving a circular economy in Asia. However, it is still not an official practice, and many cities continue to utilise open dumping, involving receiving mixed waste without pre-treatment. This paper, therefore, examines the advantages of source separation of MSW and explores the main factors for success in the planning and implementation of official source separation programmes in cities in Asia. Analysis of the results for two case studies in India and Japan could be used to strengthen capacities of policymakers in designing and implementing official source separation systems to facilitate material recovery and achieve sustainable development in Asia.
