1. EVALUATION OF POTENTIAL METHANE GENERATION IN THE INVESTIGATION OF AN ABANDONED CONTAMINATED LANDFILL IN SANTIAGO, CHILE
Abstract This study presents the environmental evaluation of an abandoned and potentially contaminated landfill using analyses for the presence of heavy metals and for methane generation potential. The site is located in the city of Santiago, Chile, and was used as a rural landfill for domestic, industrial and construction waste until 1978, but is now in a h

2. Determination of CO2, CH4 and N2O: a Case Study for the City of Rio de Janeiro Using a New Sampling Method
A new sampling method using polypropylene syringes and chemical analysis by gas chromatography was proposed and applied to determine CO2, CH4 and N2O. The samples' stability was evaluated and compared with the stability of the samples in stainless steel canisters and Tedlar® bags. This methodology was applied to a case study in the urban area of the city of

4. 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

5. Estudo comparativo de alternativas para o tratamento dos resíduos de serviços de saúde: incineração e desinfecção térmica / Comparative study of aternatives for the treatment of the wastes of health services: incineration and thermal disinfection
The objective of this study is the comparison of the incineration process regarding solids waste in landfills provided by health services with the alternative of thermal disinfection with vapor currently used for the treatment of infectious wastes in a landfill. The chemical, infectious and anatomical solid wastes that are generated in health establishments

6. Geoprocessamento aplicado à gestão de resíduos sólidos urbanos na UGRHI-11 - Ribeira de Iguape e Litoral Sul / Geoprocessing apllied to the management of solid waste in UGRHI-11 - Ribeira de Iguape and southern coast
The water resources managing unit 11 (UGRHI-11), Ribeira de Iguape river Drainage Basin and São Paulo State Southern Coast, presents advances in the management of solid waste, but there are still municipalities deprived of adequate landfills. The objectives of this work are: to indicate possible suitable areas for construction of landfills for municipal sol

7. Análise da viabilidade do uso de cinzas agroindustriais em matrizes cimentícias: estudo de caso da cinza da casca da castanha de caju / Feasibility analysis of using agroindustrial ashes in cementitious materials: case study of ash of the rind of the cashew nut
Nowadays, the use of wastes on civil building has been stimulated for it to be one of most consumers of raw materials in their processes and products. The agroindustrial ashes have a prominent place among the wastes with possibilities of application in cementitious materials, because some ashes, such rice husk ash, have pozzolanic activity, and they contribu

8. 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

9. Aspectos metabólicos, fisiológicos e taxonômicos de actinomiceto produtor de exopolissacarídeos, proveniente de águas subterrâneas contaminadas (São Carlos, SP).
Strains Lc (CCT 7277) and Lg (CCT 7137), isolated from landfill leachate-contaminated groundwater and found to produce exopolysaccharides (ESP), were characterized by polyphasic taxonomy. The growth and EPS production of Lg strain on sugarcane molasses, at concentrations between 2% and 10% and on the standard GYM medium were studied and its responses to nutr

10. SEPARAÇÃO E PRÉ-CONCENTRAÇÃO ON-LINE PARA ESPECIAÇÃO DE Hg EM CHORUME POR FI-CVG AAS
In Brazil, the urban solid wastes are usually discharged on landfill sites that are percolated by rainwater. This water leaches the wastes producing an effluent that is characterized by high concentration of organic matter, salts, suspended particulates and heavy metals. Mercury is one of the metals that is frequently present in different chemical forms whic

11. Investigação geoambiental em áreas de disposição de resíduos sólidos urbanos utilizando a tecnologia do piezocone. / Geoenvironmental site investigation in waste disposal sites using the piezocone technology.
The major purpose of this dissertation is to study the applicability of the piezocone technology for geoenvironmental site investigation of tropical soils. Two waste disposal sites were investigated: a deactivated dumpsite in Ribeirão Preto and a sanitary landfill in Bauru, in São Paulo State, Brazil. Other in situ and laboratory tests were carried out in

12. Estudo da geração de biogas no aterro sanitario Delta em Campinas - SP
Disposal of waste into landfills represents one of the most important problems in urban sites, particularly in Brazil where the use of "open dumps" is still very common. Uncontrolled emission of biogas produced by anaerobic decomposition of the organic matter can be a local environmental hazard causing vegetation damage, unpleasant odors and may form explosi
