Wet mills separate the fractions of the kernel so a pure starch stream can be used for food or as a feedstock for ethanol production. The coproducts are separated in the process and can be marketed as well. But wet mills are expensive to build and operate and require chemicals such as sulfur dioxide which are regulated as pollutants.
