Their new 23 million dollar toilet, even though it is small, does seem like it would work. Their crew is also growing, so they need to keep the old toilet on board until they build another new one. Though their process for keeping the water, urine, and sweat on board and not needing any more deliveries is pretty gross. What they do is filter, process, and then recycle it all, and this is summed up in a quote from Jessica Mier pretty well, “When it comes to our urine on the ISS, today's coffee is tomorrow’s coffee.”
