Résumé:
One of the major health problems is the disposal of waste generated by the
population and industries. In the state of Paraíba, are collected daily 2,754 tons of
municipal solid waste, 30.9% of these have final disposal in landfills, 36.9% intended
to controlled landfills and 32.2% have a final destination landfills. Recycling of glass
indicates 100% reprocessing. Besides being 100% recyclable glass, when reused,
resulting in reduced environmental impact and still contributes to diversification of
manufacturing products and to decrease the final cost of its production. This work
aims to study the process of annealing of glassy waste, aiming to contribute to the
social development of a recycling technology for glass workers CAVI - Association of
Collectors and Recyclers of Glass and other Materials. For this waste flat glass and
hollow undergone five mergers and annealing with different temperature levels were
used, employing techniques of recycling glass hot (fusing and slumping). Ceramic
molds for the initial studies and gypsum for the manufacture of test specimens were
used. The resistance after annealing was examined by impact tests, it can be seen
that the samples subjected to the heat treatment study had higher impact resistance
compared to samples which received no heat treatment during the melting process.
The fractures obtained after the tests were analyzed macroscopically.
