Dissertação (Mestrado em Engenharias) - Universidade Federal de Goiás, Goiânia, 2011.http://repositorio.bc.ufg.br/tede/handle/tde/622The PET, tereftalato of ethylene, is the most known and appropriated material in the manufacture of several packings of nourishing products, specially the bottles of beverages. The correct management of the urban solid residues to the transformation into those which return to the use and the environment education are essential tasks to guarantee the exploitation of the complete useful life of this material and to prevent it on environmental focus. From the industrial point of view, the PET recycling in Brazil is still a recently activity. All around the country there are recycling industries, but they were created specially for environmental reasons. Although they became an important source of jobs and income. That s why, nowadays, recycling industries are considered an important social order factor. In Brazil, there are industries which transform the PET into roofing tiles for covering for drawing or injection. In this work, the main analyzed topic was the properties of the transparent roofing tiles of PET and other materials, the polycarbonate and the available fiberglass in the civil construction market through the main properties and relative parameters to the natural illumination, including its optic properties and the objective of the luminous and thermal comfort. Using the results of the spectrophotometer device, it was made a comparison among the studied materials in order to help the best choice of luminous and thermal comfort materials. PET, compared to the other studied materials, is not the best choice, even concerned to the price. However, for environmental solutions, the best way to use this solid waste recycling is the utilization of the PET as transparent roofing tiles, specially considering the amount of material all around rivers, scoots, attires, and so on.application/pdfAcesso AbertoPET (Politereftalato de etileno)telhas translúcidasconforto lumínicoconforto térmicoespectrofotometriaPET (Politereftalato of ethylene)translucent roofing tilesluminous comfortthermal comfortspectrophotometryCNPQ::ENGENHARIAS::ENGENHARIA SANITARIA::SANEAMENTO BASICO::RESIDUOS SOLIDOS, DOMESTICOS E INDUSTRIAISDissertação
