Whey is the main by-product of the dairy industry, which is formed during the enzymatic or acid treatment of milk, during the cheese production process. Due to its composition, whey is a good substrate for use in various biotechnological processes, which include the production of lactose, protein concentrates and hydrolysates, functional fermented beverages, enzymes, etc. Due to the numerous useful properties of whey, the aim is to establish new procedures in order to obtain products from it that would have daily application. In article according to performed research, proposes the possibility of applying the „SuperPro Designer software package“ for modeling and analysis of technical and economic variability, including risk analysis and analysis of the impact of pollution reduction through the whey processing unit with integrated production of concentrated protein (WPC 80) and lactose powder (LAC 80). Based on the results of the economic assessment of the factories for the production of WPC 80 protein concentrate and whey lactose LAC 80 and the internal rate of return (IRR) after deducting all costs, it was determined that the production is economically justified and can be accepted.
