Resumo: The objective of this study was to assess the technical and economic feasibility of the use of whey resulting from the cheese making process in the State of Rio de Janeiro. Data was collected from 52 dairy plants that produce or buy whey, by means of questionnaires. Based on the data obtained, a mathematical model for the location of processing plants was built, considering production logistics, sample collection, regions with potential to locate whey processing plants and possible areas of environmental impact from cheese industries. Whey processing was more concentrated in the south of the state of Rio de Janeiro, with 59.5% during the season, and 58.4% in the off-season period. The production in the season and off-season periods was stable, with good distribution throughout the State. Only 30.7% of the total whey generated was used by industries to produce dairy beverages and ricotta, and 70.3% was discarded. According to the present study, the ideal solution for the use of whey in the referred region, should consider the establishment of two processing plants and the definition of strategic convergence points (whey drying facilities, in Macuco and Valença), and the subsequent transport of the products for final processing.
