I can't seem to get the right search terms on this one but IIRC some genius in France (?) got the idea to feed cows ground up sheep offal etc instead of "wasting" plants on it (or something like this). If some fren remembers specifics better on this and can help out that would be swell (or prove me wrong since this is very hand-wavy obviously).
A (((business man))) fed ground up cattle left overs back to the cows instead of discarding the waste.
