Like I said, Tsukiyama's excuse would make no sense since he hadn't consumed human food. It comes across exactly the same as a human, including Hinami being puzzled by him taking so long.

But seriously, there is no such thing as an organism that doesn't produce waste products. The body filters out toxins, minerals, and unused filler through those processes to maintain health. Especially with the modern human diet, there's going to be plenty of toxins to filter out of the body.
