Reaproveitamento de resíduos de embalagens Tetra Park em coberturas

Abstract

This research aimed at evaluating the recycling of Tetra Pak ® packaging, along with fiber cement tiles, and the efficiency of the tiles recycled with Tetra Pak ® packages regarding thermal comfort in physical models of reduced scale rural facilities. In order to test the different roofing materials, we constructed six models in distorted scale of 1.25 m in height, 1.20 m width and 1.50 m of length. The experimental treatments were: tiles recycled from Tetra Pak® packages, fibro cement tiles, aluminum tiles, fiber cement tiles with under-coverage of Tetra Pak® packages with the aluminum side facing up, and fiber cement with lining of Tetra Pak ® packages with the aluminum side facing up. The data were collected in the period from December of 2012 to February 2013, from 9 to 17 hours in 20 minute intervals. From the results obtained we may affirm that the recycled tiles presented thermal comfort indexes with values similar to those presented by other roofing materials, such as ceramic tiles. With the use of thermo graphic images, it was possible to observe that the recycled tiles also presented lower surface temperature values, demonstrating the efficiency of the tile in reducing heat absorption. The recycling of Tetra Pak ® packages as lining contributed to reducing the average values of ITU, BGT and CTR.
