Reusable human waste? It seems gross but possible

Japanese scientist Mitsuyuki Ikeda from the Okayama Laboratory certainly doesn't believe in human waste.

He thinks that's perfectly good protein you're sending out to sea, and he's found a way to extract it, mix it with steak sauce and create a fecal feast fit for a king. And despite the downside of having to add soya to bind it all together, Prof Ikeda thinks there's no reason why we shouldn't all tuck into his turd burgers.
