14. 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

15. Seleção de áreas aptas a disposição de lodo de estações de tratamento de esgoto com fins agrícolas / Selection of areas suitable for the disposal of sludge stations sewage treatment for agriculture
Overcrowding in urban centers has spawned many impacts on the environment, highlighting the waste generated by their activities. To properly allocate these wastes, technologies are developed such as those involved in sewage treatment. However, this form of treatment also generates waste, which must be treated and disposed of properly. The sludge is a byprodu

16. AvaliaÃÃo do processo de bioestabilizaÃÃo de resÃduos sÃlidos urbanos em LisÃmetro de campo
The solid wastes, formed at the most part of it by organic materials, bear biological degradation associated by others physical and chemical processes. These residues, deposited in landfill, are treated through anaerobic degradation; which engender, as a final result of the decomposition, leaching and bio-gas. However, these sub products can be studied and t

17. Uso dos resíduos da construção civil para a produção de pavimento intertravado a base de concreto de cimento portland e escória
Construction and demolition are two steps where the generation of waste is imperative, given the low industrialized processes. Due to the growth of cities, the demand for raw materials is becoming more expressive and their deposits more distant from consumer centers. Consequently there is an increase in the generation of rubble and storage areas. The granula

18. 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

19. Diagnóstico e avaliação das áreas de destino final dos resíduos sólidos urbanos no estado do rio grande do norte / Diagnosis and assessment of areas of final destination of solid waste in the state of rio grande do norte
This work aims to present the diagnosis and the evaluation of areas of final destination of urban solid waste in Rio Grande do Norte (RN) state. The survey was based on the experience of the State of São Paulo, which made its first inventory in 1997, through its Companhia de Tecnologia de Saneamento Ambiental CETESB. The methodology for the structuring of d

20. Efeitos citotoxicos e genotoxicos no meristema radicular de Allium cepa exposta a agua do Rio Paraiba do Sul - estado de São Paulo - regiões de Tremembe e Aparecida / Citotoxic and genotoxic effects in the root meristem of Allium cepa exposed to the water of the Paraiba do Sul river - São Paulo state - regions of Tremembe and Aparecida
One of the main sources of pollution of fresh water ecosystems refers to the discharge of industrial and urban wastes. Untreated sewage is considered an important cause to the deterioration of water quality in developing countries. Environmental pollutants have caused a decrease in water quality, inducing harmful effects in organisms which are in direct or i

22. First genotoxicity study of Paraná river water from Argentina using cells from the clam Corbicula fluminea (Veneroida Corbiculidae) and Chinese hamster (Cricetulus griseus Rodentia, Cricetidae) K1 cells in the comet assay
High concentrations of xenobiotics from urban and industrial wastes have contributed to the contamination of many aquatic environments. We used the comet assay to evaluate the genotoxic potential of water collected from the River Paraná, which receives a great deal of waste, at three points (Puerto Piray, Eldorado and Montecarlo) in the Misiones Province of

24. Use of stabilized sewage sludge in revegetation of a decapitated soil / Uso de lodo de esgoto estabilizado na revegetação de um solo decapitado
One of the consequences of urban population growth was the emergence of various environmental problems in the most of urban cities in Brazil, mainly the deterioration of water resources and land degradation caused by inadequate disposal of various types of waste generated by cities. In order to evaluate the use of sewage sludge composted with waste of grass
