The proposal of this work is to evaluate a feasible alternative to minimize the environmental problem caused by the disposal of liquid waste from cheese production in the municipality of Nossa Senhora de Lourdes, in the state of Sergipe, Brazil. Moreover, it also proposes the recovering of whey proteins which have a high economic value for several industrial sectors. At present, the whey has been disposed of without any treatment, damaging the environment and resulting in the loss of whey proteins, although they constitute a profitable economic alternative as well as a rich feed resource. With the objective of evaluating the dimensions of the problem, surveys were carried out at the cheese manufacturers in that municipality in order to verify the economic, social and environmental conditions of the region. Whey samples were collected for laboratory tests and analyses. The survey results have shown that subsistence farming is one of the main economic activities in that municipality. The local community complains about the lack of alternatives to the promotion of socioeconomic development. The tests and analyses of the milk serum in cheese making reveal a high level of organic substances (49.000 mg/L), which can contaminate the ground and compromise the quality of water resources. This action can be minimized through the appropriate waste treatment by ultra-filtration. In this work, it was possible to concentrate the whey proteins in 36,85% and reduce the Biochemical Oxygen Demand (BOD) to 30,61%. With this result, it is possible to obtain lower pollutant emissions to environment and it values are added to an abundant municipal product. Therefore, is possible to promote industrial growth balanced with sustainable development, implementing alternatives that can minimize social, economic and environmental inconveniences at the semi-arid region of Sergipe, aiming at assuring better quality of life for the community of that region.
