Whey has a high amount of organic compounds, which ends up making it a polluting by-product, which when released into the environment without any treatment has a pollution capacity 100 times more than domestic sewage. This work aims to carry out a literature review on whey, disposal and reuse, aiming to identify the best reuse practices in new products. This study is a biblio-graphical review, as well as research for scientific articles were obtained from the following electronic data sources such as Scielo, Lilacs and Google Schol-ar. The following descriptors were adopted for the search: whey, use and en- vironmental impacts. The use of whey in the dairy industry becomes possible due to the application of different technologies and reuse of whey to create new products. However, research on the reuse of serum is still limited, even though serum has long been considered a source of contaminants.Acesso AbertoAproveitamentoImpactos ambientaisSoro de leiteUtilizationEnvironmental impactsWheyTrabalho de Conclusão de CursoCIÊNCIAS AGRÁRIAS
