The consumption of water and chemical products in textile industries/laundries is high, thus requiring alternatives to mitigate impacts on the environment. Thus, this study aimed to analyze the consumption of polluting water and chemical products used by the jeans processing industries in the Agreste Pernambuco state. The work was developed in three cities in Agreste Pernambucano, known as the textile hub. Questionnaires were applied in 18 textile industries/laundries in order to find out the consumption of raw water, the percentage of treated effluents, the volume of water deposited in the rivers and the amount of chemicals used in each step of jeans processing. The consumption of raw water, chemical products, reuse and the production of jeans increases, as companies grow in relation to size. The commercial product called Softener, hydrogen peroxide active ingredient is the most used by textile industries/laundries in the harsh Pernambuco. The larger the size of the textile industry/laundry, the higher the consumption of water, chemicals and effluents discharged into rivers. Potassium permanganate is one of the chemicals used in the processing of jeans, more polluting and persistent in aquatic environments. Textile industries/laundries are major polluting agents, since they use high volumes of water and chemicals, requiring stricter standards regarding the emission and dumping of their waste. The search for alternatives is necessary to reduce the consumption of raw water, such as reuse, continuous maintenance of machines and replacement of polluting chemicals with sustainable techniques.
