Avaliação de uma manta têxtil na construção civil: estudo de caso em telhados verdes

Abstract

The study analyzes the use of geotextile mats made from textile waste in green roofs, highlighting their positive influence on soil quality and stormwater management. Located in Apucarana, PR, it evaluates the feasibility of green roofs as a sustainable solution to address the impact of textile waste and control rainwater drainage. Additionally, it details the composition of the waste mats, considering their density, manufacturing method, and fibers used, and implements green roof prototypes in a specific local context. For result analysis, the collected water sample values and the mats' effectiveness were interpreted. The runoff coefficient and the color of the water samples from the reservoirs were assessed. The mats' effectiveness was analyzed by comparing the amount of rain measured by the rain gauge and the water collected in the reservoirs, determining the surface runoff capacity. The results revealed that the mats produced from textile waste outperformed commercial ones in various aspects, including mechanical strength of 171 N for the crafted mat and 52.5 N for the commercial one, and water retention capacity, with runoff coefficient values of 0.039 and 0.08, respectively. Additionally, they demonstrated superior filtration capacity, resulting in cleaner and better quality water. The study also emphasizes that environmental factors, such as the presence of roots and soil compaction after rain, further contribute to improving the performance of the waste mats. In summary, the study concludes that textile waste mats offer a viable and sustainable option for green roof projects and stormwater management. Their advantages include enhanced strength, efficient water drainage, and quality filtration, reinforcing their suitability to promote environmental sustainability and optimize the use of natural resources.
