25. Alternativas de financiamento de projetos de biogÃs e geraÃÃo de energia elÃtrica em aterros sanitÃrios: estudo de caso
The objective of the present essay is to analyze how to make feasible the financing of projects for the collection of biogas and the generation of electric power in sanitary landfills, inserted into the clean development mechanism (CDM) of the Kyotoâs Protocol. The exploratory research assesses the current stage of the solid residues in Brazil, the means fo

26. Alternativa de melhoramento de solos tropicais para uso em sistemas basais de selagem, através da aplicação de bentonita
Among all the constructive elements in waste containment systems (e.g. sanitary and industrial landfills and waste ponds), liners and cover systems have been seen as the greatest concern. In Brazil, the use of compacted lateritic soil for this purpose is widely accepted, due to the great occurrence of this type of soil. At the same time, the proposal of usin

27. Estudo comparativo das caracterÃsticas dos lÃquidos percolados gerados no Aterro Metropolitano â PB e no Aterro da Muribeca â PE
The way of final disposition used for homely urban solid waste in Brazil and throughout the world has been sanitary embankment, which can be applied for both small and big communities. It is important to mention in this method, the treatment of the liquids that are not generated inside the heap of refuse, named leachate, which produces the percolate when mix

28. Removing heavy metals from the percolate subjected to recirculation in the urban solid residue columns / Remoção de metais pesados de percolado submetido à recirculação em colunas de resíduo sólido urbano
Com a realização desse trabalho, objetivou-se avaliar a capacidade do resíduo sólido urbano estabilizado (RSU velho), de cerca de 20 anos de idade, retirado de lixão em remover metais pesados presentes no percolado produzido por resíduo sólido urbano recém coletado (RSU novo), além de avaliar a influência da presença da camada de resíduo de const

30. Percepção da influência da forma de disposição final de resíduos de serviços de saúde sobre a ocorrência de fatores de riscos aos trabalhadores de aterros sanitários
This research presented a qualitative analysis of the heath of the workers of sanitary landfill, comparing the co-disposal of heath services wastes - HSW, together with municipal solid wastes - MSW and the disposal of the forms in septic trenchs. The methodology dealt with an approach of the reality, through meanings, reasons, aspirations, attitudes, faiths

31. STUDY OF THE HYDRAULIC CONDUCTIVITY OF SOILS FOR DISPOSAL OF SOLID WASTE IN THE REGION OF SANTA MARIA / ESTUDO DA CONDUTIVIDADE HIDRÁULICA DE SOLOS PARA A DISPOSIÇÃO DE RESÍDUOS SÓLIDOS NA REGIÃO DE SANTA MARIA
The study of hydraulic conductivity of soil is an important stage in the geotecnical investigations, aiming at the use of compacted soils as impermeabilizing mineral layers, for the base and cover of sanitary land-fill sites. This paper presents the study of hydraulic conductivity (k) of natural and compacted soils of the Santa Maria region, in the area call

32. Aproveitamento de Lodo de Estação de Tratamento de Água em Cerâmica Vermelha
The water treatment stations (WTA) have been researching solutions for the recycling of the residue generated in the water treatment process this residue is called WTA mud. Presently, the adopted solutions are the releasing of the residue into sanitary landfills or into the sewer system. The red ceramics presents an enormous potential to contribute for the s

33. SIMULAÇÃO DO PROCESSO DE COMBUSTÃO DE GASES PROVENIENTES DE ATERROS SANITÁRIOS / SIMULATION OF THE COMBUSTION PROCESS OF SANITARY LANDFILL GAS
The utilization of the sanitary landfill gas for electric power generation shows how the solid waste environmental problems can be reverted to environmental and economical benefits. This screen shows results about waste composition in sanitary landfills and investigates its utilization as energy source through biogas combustion. A model based on finite volum

34. Tratamento de chorume de aterro sanitario usando eletrolise foto-assistida / Treatment of landfill leachate by photo-assisted electrolysis
Sanitary landfills are the major method used today for the disposal and management of municipal solid waste. Decomposition of waste and rainfall generate leachate at the bottom of landfills, causing groundwater contamination. The leachate is a dark grey, foul smelling solution and it can be considered a complex effluent, often containing organic compounds, h

35. Study on the possibilities of recycling of wastewater treatment wastes generated in the Metropolitan Region of São Paulo. / Estudo das possibilidades de reciclagem dos resíduos de tratamento de esgoto da Região Metropolitana de São Paulo.
The objective of this work was to investigate the options for the management of wastes generated from wastewater treatment plants, which were technically, environmentally, socially and economically feasible. The wastewater treatment process generates non-inert solid wastes among which the sludge is the most significant due to the amount produced. In the Metr

36. Compactação e compressibilidade de resíduos sólidos urbanos / Compaction and compressibility of municipal solid waste
The objectives of this research were to: (i) study the compaction characteristics of municipal solid waste (MSW); (ii) evaluate the compression mechanisms of MSW and its response to a surcharge (waste test fill) over an existing landfill; (iii) develop a computer program for landfill settlement predictions. A waste test fill with a volume of about 24,400 M P
