25. O espaço dos resíduos sólidos domiciliares e de sua logística reversa na geografia urbana: diagnóstico e modelo de gestão pró-ativo
The present study investigates the reversal logistic of waste in urban geography and proposes a model of proactive management. As methodological principles, were used bibliographical review, field research and document analysis. In order to reflect this context, concepts like reverse logistic, urban space, selective collection, environment, solid waste, sust

26. Avaliação da ecotoxicidade de percolados em áreas de disposição de resíduos na região metropolitana de Natal/RN
Leachates are effluent produced by decomposition of solid waste, they have complex composition and can be highly toxic. Therefore such percolated liquid should be collected and treated properly to avoid environmental contamination of soil and of water bodies. The objective of this study was to evaluate the toxicity through ecotoxicological tests with Cerioda

27. Lixiviado de aterros sanitários brasileiros: estudo de remoção do nitrogênio amoniacal por processo de arraste com ar ("stripping") / Sanitary landfill leachate in Brazil: evaluation of ammonia nitrogen removal by air stripping process
Sanitary landfills are considered as the most appropriate way for final disposal of municipal solid wastes in Brazil, in the technical and economical point of view. Open dumps have been progressively substituted by well engineered and operated landfills. However, landfills still present environmental risks due to the gas emission and leachate production. Gas

28. Measurements of gas emissions at eight solid waste landfills of the state of São Paulo - Brazil / Medidas da emissão de gases em oito aterros de resíduos sólidos urbanos do Estado de São Paulo - Brasil
Urban solid waste disposal landfills are equipments that must be integrated with the drainage and protection of the public health of municipalities system. Regardless of whether they are well planned, built and operated, they offer environmental impacts to the areas where they are deployed and their surroundings. The present work aimed at measuring, as estim

29. Environmental implications from leachates attenuation processes in places of solid urban wastes disposal / Implicações ambientais dos processos de atenuação de lixiviado em locais de disposição de resíduos sólidos urbanos
Estudos recentes constataram a existência de processos que permitem a atenuação natural dos contaminantes presentes nos lixiviados. O adequado entendimento destes processos pode originar benefícios possíveis de serem aplicados em aterros antigos, novos ou naqueles que ainda serão concebidos. O presente estudo avaliou o comportamento e a atenuação de

30. Banco de dados georreferenciado para aterros sanitários de resíduos sólidos urbanos (AS-RSU) no Estado da Bahia / Georeferenced database for landfills for municipal solid waste (MSW-AS) in the State of Bahia / Banco de dados georreferenciado para aterros sanitários de resíduos sólidos urbanos (AS-RSU) no Estado da Bahia / Georeferenced database for landfills for municipal solid waste (MSW-AS) in the State of Bahia
O presente trabalho apresenta critérios para a criação de um banco de dados georreferenciado em um sistema de informações geográficas para aterros sanitários de disposição final de resíduos sólidos urbanos no Estado da Bahia. Abordaram-se aspectos relacionados aos resíduos sólidos urbanos, na forma de disposição final em aterros sanitários e

31. Remoção de nitrogênio de lixiviado de resíduos sólidos urbanos por meio do processo nitrificação/desnitrificação via nitrito em reator em bateladas sequenciais / Nitrogen removal from solid waste leachate by nitrification/denitrification via nitrite in a sequencing batch reactor.
The leachate is an effluent with high potential to cause environmental problems in receiving body due to the high concentrations of ammoniacal nitrogen. Currently, several treatment processes have been studied to promote nitrogen removal by the hand of conventional process variations. Therefore, the present study was developed to evaluate the performance of

32. Simulação de fluxo de água e transporte de solutos na zona não-saturada do solo pelo método de elementos finitos adaptativo / Simulation of water flow and solute transport in the unsaturated zone of the soil by adaptative finite element method
Devido aos riscos de contaminação dos recursos naturais solo e água, ao alto custo, ao tempo e ao esforço humano nas investigações de campo, os modelos matemáticos, aliados às técnicas numéricas e aos avanços computacionais, constituem uma ferramenta importante na previsão do deslocamento de solutos, contribuindo assim, para o controle de altera�

33. Tratamento de lixiviado de aterro sanitário por um sistema composto por filtros anaeróbios seguidos de banhados construídos: estudo de caso - Central de Resíduos do Recreio, em Minas do Leão/RS / Sanitary landfill leachate treatment for a system composed by upflow anaerobic filters followed by constructed wetlands: case study - Recreio Central Waste, in Minas do Leão/RS
This study discussed the sanitary landfill leachate treatment in a full scale system composed by two upflow anaerobic filters followed by two constructed wetlands. The research was developed at the landfill leachate treatment station owned by Recreio Central Waste, located in Minas do Leão/RS. The objective of the study was to verify the efficiency of the s

34. Evaluation of the mitigating mesure related to the physical environment, formulated in environmental impact assessments and environmental empact reports, (EIA/RIMA) of sanitary landfills in the state of São Paulo / Avaliação das medidas mitigadoras relacionadas ao meio fisico, formuladas em Estudos de Impactos Ambientais e Relatorios de Impactos Ambientais (EIAs/RIMAs) de Aterros Sanitarios no Estado de São Paulo
The Environmental Impact Assessment (EIA) has been used as a procedure for environmental licensing in Brazil for the last two decades but the results from performing such assessment are still not well known due to the lack of follow-up surveys. As a result, the EIA s efficiency is uncertain. Therefore, it is necessary to develop a methodology to evaluate its

36. Use of geographic information system in watershed management of water treatment plants sludge / Uso de sistema de informações geograficas na gestão do lodo das estações de tratamento de agua de uma bacia hidrografica
Present work investigates the use of geographic information system (GIS) - nowadays a necessary technique for spatial data analysis, broadly used as decision-making aid in many fields - as a tool for watershed management for disposal or beneficial use of water treatment plants (WTP) sludge. Most of times, residuals management is based in conventional data, c
