13. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

14. Estado da arte dos aterros de resíduos sólidos urbanos que aproveitam o biogás para geração de energia elétrica e biometano no Brasil
RESUMO O aproveitamento do biogás gerado a partir da decomposição da matéria orgânica dos resíduos sólidos urbanos (RSU), além de ser uma fonte renovável de energia, também contribui com a redução do lançamento de metano e do dióxido de carbono (CO2) na atmosfera, que são importantes gases de efeito estufa (GEE). No entanto, o biogás é pouco

15. Bond between steel and concrete made with ceramic waste aggregate
Abstract The reduction of natural resources combined with a substantial increase in the generation of solid waste in large urban centers, justifies the search for methods of reusing the construction industry waste. The ceramic industry has a high disposal rate during the manufacturing, transportation and eventual replacement of its products. In this case, re

16. Caracterização da cinza de caroço de açaí residual para adição ao concreto
Resumo Os problemas ambientais são uma realidade do mundo atual e vêm associados ao crescimento urbano e populacional, com pouco ou nenhum planejamento. O setor da construção civil é um dos maiores consumidores de recursos naturais e gerador de resíduos sólidos. Assim, é interessante pensar em uma maneira de incorporar materiais que hoje são conside

17. PRO-ENVIRONMENTAL BEHAVIOR AND RECYCLING: LITERATURE REVIEW AND POLICY CONSIDERATIONS
Resumo O cenário ambiental exige a participação da sociedade na integração das responsabilidades individuais com as ações políticas. O comportamento pró-ambiental de reciclagem contribui para a adequada destinação de resíduos sólidos, um dos principais desafios na gestão pública urbana. Objetivou-se analisar as produções científicas sobre o

18. Construction and demolition waste in concrete: property of pre-molded parts for paving
Abstract Construction and demolition waste (CDW) production is a growing factor on a global scale and its incorrect disposal becomes an increasingly common problem in cities. It is estimated to represent, on average, 50% of the urban solid waste mass in the world. In this sense, an alternative to the destination is their reuse. In this work, the properties o

19. Comportamiento del residuo de vidrio molido en cementos mezcla: Estudio comparativo con microsilice
ABSTRACT Due their high content of silica in an amorphous state the glass, in theory, can behave as pozzolanic material when are finely ground. This opens up an interesting way of reusing these materials in the Portland cement industry (CP), especially considering that solid urban waste (RSU) in Argentina contains between 3 and 5% by weight of glass. This pa

20. Riesgos laborales en las empresas de residuos sólidos en Andalucía: una perspectiva de género
Abstract The Urban Solid Waste sector has a great trajectory in the implementation of preventive plans in workplace risks. We analyzed two aspects: which are the factors of workplace risks to what the employees are exposed and can essentially affect their health inside of the analyzed sector; and the differences in preventive management performed in companie

21. 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

22. URBAN SOLID WASTE MANAGEMENT BY PROCESS MAPPING AND SIMULATION
Adequate management of urban solid waste (USW) is beneficial to the environment, cities and people who depend on the income generated from collecting this waste material to survive. Due to the level of complexity of these processes involved in recyclable USW sorting, management tools which enable systemic studies become valuable assets by evaluating the effe

23. Characterization of polyurethan skin agglomerates for acoustic insulation from impact noise
Polymeric materials are greatly used in industry due to their versatility in application generating therefore, large quantities of solid waste. Population growth in urban areas, with living quarters mainly in residential buildings, face discomfort caused by noise, particularly by impact noise. Aiming at reducing the amount of polymeric material disposed of i
