Every day, large quantities of whey are produced as a byproduct by the dairy industry. In Germany alone, this amounts to 12.6 million tons a year. For each kilogram of cheese, for example, 9 kilograms of whey are produced. Some of this is processed further, for example into whey-based drinks with fruit additives or other mixed drinks. The lactose and proteins contained in the whey can also be separated and used in other ways, for example, as a raw material in pharmaceuticals or in baby food. However, once the proteins and lactose have been separated, molasses remains. Disposing of this substance is very complicated and expensive, due to its relatively high salt content.
