Contudo, apenas no século XIX iniciaram-se esforços para o desenvolvimento de métodos sanitários de disposição final. Ainda hoje, em países subdesenvolvidos predominam formas de disposição incorretas como lixões e aterros controlados, responsáveis por grande poluição ambiental e pela veiculação de doenças. Uma disposição final adequada dos resíduos sólidos urbanos se inicia com a escolha de locais favoráveis do ponto de vista ambiental. A presente pesquisa teve por objetivo comparar dois métodos de seleção de áreas para implantação de aterros sanitários: o de IG-SMA (1999), e o de Basílio (2001). Os referidos métodos foram escolhidos por terem sido desenvolvidos e aplicados em uma mesma área geográfica (região de Campinas - SP). A comparação por superposição mostrou que apesar da área geográfica ser a mesma, os resultados de ambos foram diferentes. O fato é explicado pela diferença de escalas, critérios, atributos e classes, e chegou-se à conclusão que o método de Basílio (2001) apresentou muito menos áreas favoráveis à disposição de resíduos do que IG-SMA (1999) por ser mais restritivo em seus critérios de seleção. / Historically, the incorrect waste disposal has been related to epidemics which resulted in thousand of deaths. Despite the efforts to develop sanitary disposal methods in the 19 century, even today, uncontrolled dumps are often found in undeveloped countries. These places are responsible for environment pollution and for several diseases. The process of adequate waste disposal begins with the selection of suitable landfill areas, based on environmental characteristics. The goal of this research was to compare two methods of landfill site selection: the first one developed by IG-SMA (1999), and the other by Basílio (2001). Both methods were developed and applied in the same area - region of Campinas, São Paulo State, Brazil and this fact explains the choice for them; the comparison was made by superposing maps. Despite the same geographic area, the result was very different and few areas in common were found; IG-SMA (1999) obtained more suitable areas than Basílio (2001). This has been attributed to scale, criteria and attribute differences and, as a conclusion, Basílio (2001) was considered more restrictive than IG-SMA (1999).

O objetivo desta dissertação é analisar as partes integrantes do sistema de gerenciamento de resíduos sólidos domiciliares do município de Ilha Solteira - SP, desde a geração dos resíduos sólidos nas residências até a sua destinação final em aterros e/ou separação e comercialização pela cooperativa de materiais recicláveis do município. A pesquisa foi dividida em três etapas. A primeira etapa consistiu em realizar um levantamento de dados sobre a destinação dos resíduos sólidos domiciliares no município de Ilha Solteira – SP. A segunda etapa consistiu em entrevistar os munícipes com o objetivo de levantar qual é o tamanho da parcela da população que realiza a separação dos materiais recicláveis, como estes são acondicionados e quais os materiais que são separados. E a terceira etapa foi a caracterização gravimétrica dos resíduos sólidos domiciliares destinados ao aterro sanitário, segundo o método de quarteamento. A pesquisa forneceu resultados sobre a redução da vida útil do aterro sanitário, a quantidade de materiais com valor econômico que está sendo desperdiçado no aterro e a renda que deixa de ser gerada para as pessoas diretamente envolvidas com a comercialização dos materiais recicláveis. Com os resultados obtidos nesta pesquisa, a municipalidade que opera e gerencia os resíduos sólidos terá informações que poderão subsidiar o planejamento e as ações de curto, médio e longo prazo; no sentido de melhorar a eficiência e as condições econômica, ambiental e social do sistema de gestão dos resíduos sólidos domiciliares de Ilha Solteira – SP / The efficient management of solid waste directly impacts the welfare of the entire population of the city, but especially those working with the collection, separation, and marketing of recyclable materials. The objective of this dissertation is to study the integral parts of the management system of solid waste in the city of Ilha Solteira-SP, from the generation of solid waste in the home until its final destination in landfills and/or separation and the cooperative for marketing recyclable materials of the city. The research will be divided into three phases. The first step will be to conduct a survey of preliminary data on the allocation of household solid waste in the city of Ilha Solteira-SP. The second stage is to interview the townspeople in order to discover what portion of the population carries out the separation of recyclable materials, wich of these are wrapped and which materials are separated. The third step performed is gravimetric characterization of household solid waste destined for the landfill, using methods of quartering. From the results obtained in this research, the municipality that operates and manages the solid waste will have information that could support the planning and the actions in short, medium and long term, to improve the efficiency and effectiveness of economic, environmental, and social management system for solid waste Ilha Solteira - SP. It will be known: the amount of materials with economic value that are being wasted in the landfill, as well as an estimate of the remaining service life of the landfill, and the income that is not generated for the people directly involved with the marketing of recyclable materials

Cellulose to lignin ratio is one of the widely used indicators of degree of landfill stabilization. This ratio shows the amount of carbohydrate or cellulose consumed by anaerobes compared to relatively inert lignin. However, the method of lignin measurement contains an intrinsic error. Plastics are contained in the landfill samples and these are characterized as lignaceous materials due to their acid-insolubility. Lignin is typically measured as the organic residue that is acid insoluble but is combustible upon ignition. Additionally lignin may degrade under anaerobic, high temperature conditions associated with wet conditions in sediments and bioreactor landfills. In this study, it has been found that the typical measure of lignin, a gravimetric measure, also includes plastics, leading to erroneous measures of both lignin and the cellulose/lignin (C/L) ratio. Typically, 100% of the plastic will be measured as lignin. Since plastic amounts to approximately 10% of landfill contents, lignin measurements will be 10% greater than actual amounts. Laboratory reactors were set up with known amounts of paper and plastic. The degradation of the cellulose and lignin in paper was measured and compared to plastics, which was collected by hand and weighed. Ratios of cellulose to plastics and lignin to plastics were obtained. It was found, based on the cellulose to plastic ratio and lignin to plastic ration that lignin degrades under anaerobic conditions although at a much slower rate than cellulose. These findings indicate that the cellulose to lignin ratio cannot be used as the sole indicator of stabilization in the landfills. The inclusion of the biochemical methane potential test data along with C/L is thought to provide a better indication of landfill stabilization. / Master of Science

In general, the improper disposal of waste may hinder the constitutional guarantee of a right to an environment to human health or well-being. This is especially true of domestic solid waste, a particular area of the waste stream frequently disposed of on South Africa's vacant land, rivers and streets amongst other. There is need therefore for municipalities as locally based authorities that are constitutionally bestowed with specific functions and duties in relation to waste, to ensure effective domestic solid waste management. The aim of this study is to investigate the content and design of some legal instruments aimed at domestic solid waste management in two municipalities of South Africa’s Limpopo Province namely the Lephalale and Greater Tzaneen Municipalities. The investigation and critical analysis of the selected instruments are based on the content of South Africa’s national waste law and policy with respect to domestic solid waste management specifically. The study concludes with a number of observations and recommendations with respect to the investigation instrumentation of Lephalale and Greater Tzaneen Municipalities. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014
