almost all soy is pressed for oil. what is fed to livestock is almost entirely industrial waste from that process.
Using it to make plant-based meat alternatives or tofu or soy milk would be more efficient than feeding it to animals, where most of the nutrients and calories are used up by their metabolism.
yea. we do. but we don't use all of it for human food. i don't see anything better to do with the industrial waste than feed it to livestock.
After extracting the protein and nutrients for plant-based products there's not much nutrition left to use it as animal feed though. It's probably not nutritionally appropriate for cows, pigs and chickens at that point. Using it for insect farming would seem more realistic to me, or as a growth medium for edible mushrooms.
when you have a ton of soy cake, I guess you can decide what to do with it.
