SUMMARY:

The Textile Center of Agreste de Pernambuco stands out for its participation in the global market for garment processing carried out in industrial laundries located in the Local Productive Arrangement of Clothing. However, this sector still faces significant challenges regarding water consumption and the generation of effluents in its processes. Textile laundries are responsible for high water consumption and the production of contaminated effluents that have the potential to compromise environmental quality in the region. In this regard, appropriate measures for water management and strategies for controlling pollution from generated wastewater have become necessary to promote efficient water and effluent management in textile processing, as well as to favor environmental sustainability in the processes. Therefore, this study aimed to evaluate alternatives for optimizing water and effluent management and promoting environmental sustainability in laundries of the Textile Polo of Agreste de Pernambuco, based on a case study in the municipality of Caruaru-PE. To achieve this, the research was developed through actions that included evaluating water usage and effluent generation in the studied laundry, characterizing the waters used in washing and the effluents generated in production processes, investigating alternatives and possibilities for physicochemical treatment improvements of the effluents, and analyzing scenarios for implementing water reuse practices in the laundry's production process. Based on the results obtained in the study, the need to consider measures for conscious water consumption in laundries and the search for more efficient processes to reduce consumption and minimize environmental impacts related to the use of this resource were identified. The characterization of the effluents generated in the process revealed characteristics related to the presence of chemical compounds, high chemical oxygen demand, intense color, high electrical conductivity, alkalinity, hardness, and the presence of solids and metals. Regarding the effluent treatment carried out in the laundry, opportunities for improvements were identified concerning the treatment system in order to comply with regulatory requirements and achieve environmental quality. Additionally, possibilities favoring the implementation of water reuse throughout the laundry's production process were identified, including the use of wastewater generated in intermediate washing processes. However, it is important to note the need for further analysis for the selection of additional treatments and studies on modifications in effluent collection and transportation throughout the washing processes. Thus, the study highlighted important aspects for reducing environmental impacts in textile processing activities in the local context of laundries in the Textile Center of Pernambuco and for implementing a production with prospects of technical and environmental feasibility.
