Item Estudo do comportamento mecânico de argamassas de revestimento com substituição parcial do agregado miúdo por lodo têxtil gerado pela lavanderia industrial de jeans do arranjo produtivo local de confecções do Agreste pernambucano(2024-09-30) Brito, Eyshila Paloma Costa de; Holanda, Romildo Morant de; http://lattes.cnpq.br/4283130448063981; http://lattes.cnpq.br/0065466719471642The local productive arrangement (APL), located in the Agreste region of Pernambuco, is the second largest textile hub in Brazil, producing, making and selling garments. The activities carried out in the region range from the manufacturing process to the processing of jeans, which is carried out in industrial laundries. As with any industrial procedure, laundries are major generators of waste, with textile sludge being one of the main ones, generated in large volumes. It is a potential pollutant capable of compromising soil, water and air quality, directly affecting the health and well-being of the population. On the other hand, the construction industry continues to be one of the biggest consumers of natural resources, mainly through the use of sand to make concrete and mortar. This research studied the incorporation of jeans laundry sludge, at levels of 10%, 20% and 25%, into mortar mixes for coatings, with the aim of providing a more sustainable destination for the sludge, as well as serving as an alternative raw material. The research aimed to study the mechanical behavior of modified mortars in order to evaluate their physical and mechanical properties after partially incorporating the waste in relation to the fine aggregate (sand). Tests were carried out on the particle size composition, unit mass and specific mass of the waste, as well as the characterization of the textile sludge. As the waste partially replaced the fine aggregate, the same tests were carried out on the sand. Although the sand and sludge had different particle size curves, both were within the usable zone for fine aggregate. Sludge had a unit mass 45% lower than that of sand. The specific mass of silt was also lower than that of sand, totaling 1.62 g/cm³ and 2.63 g/cm³, respectively. When evaluating the mechanical strength of the specimens, there was little variation between the different mixes, but the mortar with 10% sludge incorporation had the highest compressive strength and flexural tensile strength when compared to the others. In the water absorption and capillarity coefficient results, the residue was able to effectively fill the small pores in the mixture. Finally, it was possible to classify the mortars studied, which achieved minimum values for the characteristics of compressive strength, flexural tensile strength and capillarity coefficient, receiving the designation P3, R1, C1 in the four types.Item Inovação e tecnologia na indústria de beneficiamento de Denin do Agreste de Pernambuco: reuso de água para vantagem competitiva em lavanderias de jeans(2020-10-05) Silva, Bruno Lopes; Xavier, Maria Gilca Pinto; http://lattes.cnpq.br/6470044940848558; http://lattes.cnpq.br/7974481422537087The present work aims to analyze the technological innovation of water reuse used in the processing activities of industrial Denin laundries in Toritama, located in the dry region of Pernambuco. To this end, it sought to characterize the form of water reuse in laundries and the advantages in companies were compared through the reduction of production costs. The methodology used was the understanding of quantitative and qualitative aspects. In this context, a sampling of jeans laundries was carried out, whose characteristic is based on the reuse of water. It was observed that the industrial laundries for processing clothes in Denin use water in high quantity as the main raw material. The implementation of water treatment and reuse activities emerged as a requirement of the Public Ministry. As a consequence, the introduction of this innovation had an impact on the reduction of production costs and, consequently, brought a competitive advantage, while benefiting the environment.Item Reuso de água como estratégia competitiva em lavanderias de jeans no Agreste pernambucano: o caso de Toritama(2022-05-27) Silva Júnior, João Sales da; Oliveira, Isabel Cristina Pereira de; http://lattes.cnpq.br/4745142041015422; http://lattes.cnpq.br/0325504572909793Jeans laundries located in Toritama, in the countryside of Pernambuco, play an important role in the regional economy. However, the production system of this type of enterprise is linear, with cheap labor, small elaborated raw material and low technological innovation. In addition, the laundries in Toritama are located in a location with low water availability, which makes water a limiting factor in production and represents a high cost in the jeans washing process. Faced with this problem, the present work aimed to evaluate whether the adoption of technologies in water reuse can be used as a competitiveness strategy for the textile industry of Toritama/PE. A mixed case study was carried out with the application of a questionnaire on production processes and technologies in water reuse. The results show that reuse is presented as a competitive strategy in the context of laundries as it reduces the cost of producing the parts since the value of the water consumed is passed on in the final product. This makes it possible to offer low-cost jeans and guarantee the competitiveness of the laundries studied in the region.
