Potato industry side-streams consist of a significant amount of the original biomass. However, tightened demands of EU legislation together with the costs of side stream processing have forced potato industry towards more efficient use of the raw material. For this purpose, we have examined the possibility to recover main fractions from potato side streams, such as proteins, fibers and starch, and utilize them in a manner of biorefinery concept. The aim of the present research was to evaluate

Study shows, that there is enough side-streams available to build a concept, which produces more value added products, like fibers and proteins. In this report, the main conclusions of the research are presented together with state-of-art on potato waste water processing technologies and current applications of their products.
