Análise comparativa da gestão de resíduos sólidos em municípios de pequeno porte : estudo de caso /Saccá, Jamile Priscila. January 2017 (has links)
Orientador: Heraldo Luiz Giacheti / Coorientador: Jorge Hamada / Banca: Sandro Donnini Mancini / Banca: José Antônio Poletto Filho / Resumo: A Gestão de Resíduos Sólidos Urbanos compõe um dos principais itens para garantia de proteção ambiental. O objetivo principal da presente pesquisa é elaborar um estudo que analise a qualidade na gestão de resíduos sólidos em municípios de pequeno porte, abrangendo um estudo de caso para os municípios de Fernão e Gália, Estado de São Paulo. O presente trabalho foi baseado na pesquisa metodológica e empírica. Avaliando os dados obtidos, em relação ao diagnóstico socioeconômico e ao Programa Município Verde e Azul, conclui-se que os melhores resultados foram destacados pelo município de Fernão, considerando principalmente a disponibilidade de recursos e maior número de certificações. Quanto ao Índice de Qualidade de Gestão de Resíduos (IQR), ambos os municípios apresentaram valores compatíveis com a legislação vigente. Ressalta-se que o município de Fernão, na maioria do período analisado, esteve próximo do limite superior de qualidade. Considerando os Planos Municipais de Gestão Integrada de Resíduos Sólidos e os Planos Municipais de Saneamento Básico, verifica-se que em ambos os municípios há defasagem de conteúdo, não atendendo as exigências legais. Quanto à infraestrutura dos municípios, em ambos os casos as maiores dificuldades ou problemas estão relacionadas à participação da comunidade nas ações de gestão, a carência de recursos e a falta de aplicação da lei, por meio de fiscalizações. O IQG e IGR expõem que os municípios apresentaram um valor próximo do limite superior, ...

The main objective of the present research is to elaborate a study that analyzes the quality in solid waste management in small municipalities, covering a case study for the municipalities of Fernão and Gália, State of São Paulo. The present work was based on methodological and empirical research. Evaluating the data obtained, in relation to the socioeconomic diagnosis and the Green and Blue Municipality Program, it is concluded that the best results were highlighted by the municipality of Fernão, considering the availability of resources and a greater number of certifications. Regarding the Quality index of waste management (IQR), both municipalities presented values compatible with the current legislation. It should be noted that the municipality of Fernão, during the majority of the analyzed period, was close to the upper quality limit. Considering the Municipal Plans of Integrated Solid Waste Management and the Municipal Plans of Basic Sanitation, it is verified that in both municipalities there is content lag, not meeting the legal requirements. As for the infrastructure of municipalities, in both cases the greatest difficulties or problems are related to community participation in management actions, lack of resources and lack of law enforcement, through inspections. The IQG and IGR expose the municipalities presented a value near the upper limit, highlighting bette... (Complete abstract click electronic access below) / Mestre

The recycling of domestic waste in the Cape Peninsula: implications for environmental educationGobregts, Engela January 1995 (has links)
This case study investigates domestic waste recycling schemes in the Cape Peninsula with special reference to educational aspects as a basis for developing educational resource materials. It explores the question: "In what way can projects for the recycling of domestic waste serve as a vehicle for environmental education?". The study employs the concept of education for the environment, following a socially critical approach with action-oriented and participatory dimensions. The research sample constituted interviewees and/or workshop participants from fourteen different municipalities, six recycling industries, one private waste contractor and the three most prominent voluntary organisations involved in recycling in the Cape Peninsula. A small-scale -interview survey was done to review existing recycling initiatives, combined with a case study of several small participatory initiatives towards educational resource development. The results were analysed qualitatively. The case study indicates that recycling initiatives have excellent potential for education for the environment. This potential was partially explored in this research by addressing key issues such as the role of local authorities in recycling of domestic waste, the short-term perspectives on the part of the local authorities, as well as the importance of and constraints on participation in recycling projects and in the research. Other issues discussed include the educational implications of personal (economic) benefits of recycling, the social development dimension of some recycling projects, the value of school children organising recycling projects, limited teacher participation in existing recycling projects, and the need for environmental education resource material. The major value of the project lies however in critical reflection on the research process. Recommendations regarding participatory resource development as an approach to socially critical environmental education are put forward to inform similar studies in the future and to elucidate the approach. Recommendations regarding the recycling of domestic waste in the Cape Peninsula are also made.

Para o enfrentamento dessa problemática, os profissionais da saúde também devem preocupar-se com os resíduos gerados por suas atividades, exigindo dos mesmos um posicionamento consciente e disponibilidade para colaborar na busca de soluções. Desta forma, realizou-se um estudo em municípios do noroeste do estado de São Paulo, Brasil, com o objetivo de verificar o conhecimento dos profissionais da saúde atuantes nas Unidades Básicas de Saúde sobre política e práticas de gerenciamento dos Resíduos de Serviços de Saúde (RSS). Trata-se de um estudo descritivo, de caráter transversal, cujos desdobramentos foram divididos em dois capítulos. Para a coleta de dados utilizou-se um questionário que versava sobre o perfil dos profissionais participantes e questões relacionadas ao gerenciamento e manejo dos RSS. No primeiro capítulo, a amostra foi composta por 74 Cirurgiões-dentistas. Os testes Qui-quadrado e Exato de Fisher foram aplicados para verificar a associação entre o conhecimento do descarte de resíduos e a informação sobre o tema, ao nível de significância de 1%. Do total dos profissionais, 97,3% afirmam saber o que são RSS, porém 41,9% não responderam de forma correta como descartar os sugadores e luvas infectados e 20,3% os perfurocortantes. Em relação à informação sobre o tema, 40,5% não obtiveram. Além disso, houve diferença estatisticamente significante (p=0,0007) entre as variáveis informação sobre o tema e descarte de resíduos perfurocortantes. No segundo capítulo, compuseram a amostra 11 Cirurgiões-dentistas, 11 Auxiliares em Saúde Bucal, 25 Enfermeiros, 21 Técnicos em Enfermagem e 17 Auxiliares em Enfermagem. Para análise, aplicou-se o teste não paramétrico Kruskal-Wallis... / The control of sanitation of a city does not depend solely the staff of the public cleaning, but also the awareness of the general population. To face up this problem, health professionals should also be concerned with waste generated by their activities, requiring the same conscious positioning and willingness to collaborate in finding solutions. Thus, there was a study in municipalities in the northwest of São Paulo, Brazil, in order to verify the knowledge of the health professionals working in the Basic Health Units on policy and management practices of medical waste (MW). This is a descriptive study of transversal, whose developments were divided into two chapters. To collect data, we used one questionnaire that focused on the profile of professional participants and how to manage and management of RSS. In the first chapter, the sample consisted of 74 Dentists. Chi-square and Fisher exact tests were used to assess the association between waste disposal of knowledge and information on the subject, the level of significance of 1%. Of the total of professionals, 97.3% claim to know what RSS is, but 41.9% did not answer correctly disposing sucking and infected gloves and 20.3% needlestick. With regard to information on the subject, 40.5% did not obtain. In addition, a statistically significant difference (p = 0.0007) between the variables information on and disposal of sharps waste. In the second chapter, comprised the sample 11 dentists, 11 oral health assistants, 25 nurses, 21 nursing technicians and 17 nursing assistants. For analysis, we used the nonparametric Kruskal-Wallis...

Plasma gasification for converting municipal solid waste to energySerage, Noah Magonagone January 2017 (has links)
In South Africa most of the municipal solid waste is currently removed and taken to land fill sites for engraving. A very small percentage of this is recycled due to lack of exploration of alternative means of further processing. In 2011 approximately 108 million tonnes of waste, mostly being general waste was generated in South Africa. Ninety eight (98) million tonnes of this waste was disposed of at landfill sites (The Department of Environmental Affairs [DEA], 2012). Environmental engineers are finding municipal solid waste management to be a challenge, similarly do the city planners and local administration. The main reason being the difficulty brought about by the complexity in composition of the waste material, no availability of waste minimization technologies and the scarcity of land for landfill sites and their environmental impact (Lal & Singh, 2012). Anyaegbunam (2013) recommend that there is a disposal technique that can convert most of the landfill waste at reduced amount of money to what is being paid on other disposal techniques nowadays, regardless of its form or composition and produce an excess of clean energy, and that technique is called Plasma Gasification which carries a high capability of being economically efficient. According to Young (2010), plasma arc Gasification is a high-temperature pyrolysis process whereby the organics of waste solids (carbon-based materials) are converted into syngas. The syngas can also be sent to gas turbines or reciprocating engines to produce electricity. Few of these plants exist in the world, however there is none in South Africa due to municipal budgetary constraints and lack of evidence for return on investment. Gasification can be described as a thermo-chemical process wherein carbonaceous or carbon-rich feed stocks, for instance tree trimmings or biomass, coal, and petro-coke are transformed into a complex gas containing hydrogen and carbon monoxide (and smaller quantities of carbon dioxide and other trace gases) under high pressure, oxygen exhausted, strong heat and/or steam environments (SRS Energy Solutions, 2016) The problem of electricity shortages continues to increase and communities are unable to cope with the continuous rising electricity bills. It is forecast that electricity demand will grow by approximately 85% and thereby reaching 31 700TWH (terawatt hours) in the year 2035. This growth rate is anticipated at an annual rate of 2.4% of which the economic and population growth will be the driving force, while on the other hand the daily increase of waste at landfill sites poses many problems with regards to the lifespan of the landfill in case green technological disposal processes are not introduced.
