> What is an example of the good garbage that would otherwise be wasted? It seems like nutrient deficient junk food is the main beneficiary of these appetizing agents. Most of a cow, honestly. From a 1,300 lbs steer you'll get something like 600-650 pounds of usable meat (maybe a little more, depending on the breed). About a third of that resulting meat will be ground meat that'll best be used in burgers, sausages, hotdogs, and stuff like vienna sausages - which I would consider junk food. The rest of the carcass will be rendered into tallow, boiled down to produce gelatin for candy and jellies or bone broth for other dishes, and otherwise processed for human or animal consumption. It's not as extreme as the junk food you're thinking of but ever since industrialization the amount of effort put into making food from slaughterhouse waste is incredible.
