Avaliação do comportamento da temperatura na massa deresíduos com diferentes tempos de disposição no aterro sanitário de Rio Claro - SP

The present work investigates solid waste temperature behavior in different depths in two cells in the Rio Claro-SP city’s sanitary landfill. One of the cells is in operation with waste disposal beginning about one year ago. The other one is located in an closed area and contain waste disposed from five to seven years before. Measures were also made in an area that have no disposed waste in order to collect reference values. The data were obtained every fifteen days. The temperature results shows higher values in the operating cell, with maximum 38,1 °C in a depth of 4,0 m. In the closed cell the highest values were 36,3 °C in a depth of 8,5 m. The highest temperature values were obtained in the operating cell due to wider substract availability that indicates a more intense biological degradation activity. With three meters depth, the temperature results were 36,6 °C in the operating cell, 33,8 °C in the closed cell and 24,5 °C in the reference area. Therefore the temperature can be used as a biological activity indicator in sanitary landfills, supporting biogas studies

Um estudo sobre aspectos da gestão dos resíduos sólidos no município de Ribeirão Preto (SP)

Since the beginning of it’s existence the humankind coexists with the production of waste, both organics and inorganics. Over the years the world population is raising, and consequently the different kinds of waste, causing significant problems not only for the public authorities, but also for the population, not only those related with its final or temporary destination but also with its crescent production. Considering it, the cities are not able to handle there volumes, and its landfills and dumps are working over their capacities, leading to a serie of environmental problems due to the lost of environmental quality and the natural and social vulnerabilities arising. This paper plans to working over visits, photographic registration and a review on the theme literature, study the perception and valuation of the landscape on the Ribeirão Preto landfill, São Paulo state (SP), that today is disabled but still an area of risk and environmental vulnerability, well as the perception of environmental quality in the surrounding population

Mapeamento de áreas susceptíveis para implantação de aterro sanitário no município de Rio Claro, SP

The inadequate disposal of municipal waste is one of the biggest environmental problems. The lack of long public politics makes this problem a challenge to their administrators. Finding a place for the disposal of waste is an easy task and the present work looks forward to a better understanding about the concepts involved in order to choose favorable areas for the development of sanitary landfills, minimizing environmental impacts. In this line of thought several areas in Rio Claro`s region were evaluated according to the environmental terms. The areas which were classified as good or almost good will have a more elaborated study such as field works, evaluation and understanding of the concepts analyzed so that there aren’t any waste of money, work, social and environmental waste in the area. These areas were analyzed according to secondary data such as geological and pedological formation and primary studies such as the assumption of the reality as showed in the map will be made in order to acquire better results.
