Most of the waste generated by the construction are liable to reuse, and considering its
continuous generation, recycling is essential in the process of return of this waste as raw
materials replacing the extraction of new materials and resources. The objective of this study
was to characterize the construction Waste (CW) in the city of Palmas-TO. The method used
for characterization of the CW consisted of five steps: conducting interviews, selection of
potential areas using the Google Earth software, selecting the field areas, gravity waste
composition analysis and analysis of granulometry of aggregates. Have been identified
through Google Earth software, 166 sites scattered throughout the urban area and the access
roads, with a total of 54.2494 hectares. Through interviews were identified fourteen disposal
areas of waste, controlled by City Government. To make the gravimetric and particle size
composition analysis, were selected three areas through on-site visits and considering waste
characteristics, consisting of Association of collectors, degraded areas cause superficial
lavement of land fill waste and leveling of area. Gravimetric composition presented
aggregates with more concentration, followed of concrete and ceramic reminds with 67.95%,
20.06% and 4.40%, respectively. The granulometry of the highest aggregates showed
minimum mass of 2.26g and 2.86g, to 4.8mm and 37.5 mm openings sieves, and maximum
retained mass of 18.08g, and 7.42g to open 75mm opening sieve, for dry and rainy laps,
respectively. While the particle size study of fine aggregates showed minimum mass of
10.29g and 11.86g, to 1.20mm opening sieves and maximum retained mass of 33.43g and
36.11g, to 0.30mm opening sieve for dry and rainy seasons, respectively. The presence of the
municipal public power in the control and monitoring of materials in landfills of CW, presents
itself as one of the main actions of the local government for the management of this waste, in
preventing and reducing the high rate of solid waste contamination to enter this system,
besides contributing to the increase of the useful life of landfills of CW Palmas-TO city. In
addition, according to the study, the CW in the city of Palmas-TO, proved with high
contamination rate in the composition by pellets, concrete components gravimetric and
ceramics, respectively. |
