Whey cheeses are a dairy product made not from whole milk, but from the whey remaining after cheese production.
"...Many cheese products produce in the United States do contain a coagulating enzyme derived from either beef or swine. The process of changing fluid milk into cheese consists of coagulating the milk by one of two commonly used methods, each resulting in cheese having distinct characteristics.
The most common method of coagulating milk is by the use of an enzyme preparation, rennet, which traditionally was made from the stomachs of veal calves. Since the consumption of calves for veal has not kept pace with the demand for rennet in the preparation of cheese, a distinct shortage of this enzyme has developed. Consequently, a few years ago it became a common practice to mix the rennet extract from calves' stomachs with a pepsin enzyme derived primarily from the stomachs of swine. These enzymes convert the fluid milk into a semi-solid mass as one of the steps in the manufacture of cheese. This mixture of calf rennet and pepsin extract is quite commonly and widely used within the United States. [These animal enzymes are found in the 'whey' when it is listed in the ingredients listing of any other product unless it is specified 'milk whey' or 'whey from milk', otherwise it is whey from cheese production.]
A more recent development in this area has been the use of enzymes derived from the growth of pure cultures of certain molds. These are termed microbial rennets. They are commonly used for the production of certain types of cheese and contain no animal products...." [The ingredients list on the cheese will state: 'contains no animal rennet (vegetarian)' or 'microbial rennets'.] (The above 3 paragraphs excerpted from a letter by Kraft called "What's In Your Cheese?" and can be found online in its entirety)
They either dispose it or sell it whey protein factories.
Whey: the serum or watery part of milk that is separated from the curd in making cheese.
no It can not be used after making cheese

Curds and whey are the two main components of milk when it is coagulated. Curds are the solid part, which includes proteins and fats, while whey is the liquid part containing water, minerals, lactose, and some proteins. When making cheese, curds are formed by separating them from the whey.
Whey.
Rennet is added to milk and forms curds and whey. The whey is then tapped off leaving the curds.
Whey is the leftover milk components after making cheese. It contains the minerals found in milk. Demineralized whey power is whey that has had the majority (70 - 90%) of the minerals removed and then dried to a powder.
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.
I strained the yogurt to separate the whey from the solids.
whey is made from milk. more specifically:Whey is the liquid left after curds are separated from milk to make cheese.
