They either dispose it or sell it whey protein factories.
To make ricotta cheese from whey, heat the whey to a specific temperature, add an acid like vinegar or lemon juice to separate the curds from the whey, then strain the curds through a cheesecloth to create ricotta cheese.
Dried whey comes from the byproduct of cheese production. During the cheese-making process, milk is curdled, separating into curds (which become cheese) and whey, the liquid remaining. This whey is then processed to remove moisture, resulting in dried whey, which is often used as a protein supplement, in food products, or as an ingredient in baking and cooking.
Whey: the serum or watery part of milk that is separated from the curd in making cheese.

Cottage Cheese.
To make ricotta cheese using whey as the main ingredient, you can heat the whey until it reaches a temperature of about 200F, then add an acid like vinegar or lemon juice to help the curds separate from the whey.

When making cheese, milk is used and by the action of the correct bacteria, then forms curds much like you see in cottage cheese. They would then pour this mixture through a cheese cloth and twist it squeezing out the liquid which is called whey.
Whey.
Rennet is added to milk and forms curds and whey. The whey is then tapped off leaving the curds.
Whey is a byproduct of cheese production that contains protein, while whey isolate is a more refined form of whey that has had most of the fat and lactose removed, resulting in a higher protein content.
The watery liquid is called whey. The curds can then be used to make cheese, cottage cheese, paneer, and other products. Whey can be used to make ricotta, brown cheeses, and other products.
