Whey

Roughly 90 % of the milk used in cheese-making is collected as sweet whey and some as salt whey.

The degree of whey-processing depends on how the whey is to be used. In the production of whey products such as WPC (whey protein concentrate), whey powder and lactose, an advanced process technology is required.

In the production of cattle feed and fertilisers, a rather simple process that recovers only the fat and fines is required.
