Now this is sustainability in action:

Japanese researcher Mitsuyuki Ikeda has developed a new kind of meatless burger made from soy, steak sauce essence, and — brace yourself — protein matter extracted from human excrement.

Ikeda’s poop burger is literally derived from “sewage mud,” which is just a nice way of saying that it was created from human waste. By extracting the protein and lipids from this “mud,” Ikeda was able to take these components, add a reaction enhancer to them, and process the slurry into a meat-like product. Ikeda then added a steak flavoring agent, soy sauce, and food coloring to the mix, and voila, an imitation meat product that he says tastes just like real beef.
