No, I think you bring up a point that is relevant to all development. There is a point where traditional systems suited for low population areas fail, but modern (for lack of a better word) systems aren’t in reach. These are often the areas of greatest need.
And I forgot the 5th strata - those with perfectly functioning, robust sewer/septic systems who make a concious decision to use cloth and revert to the bin solution (hopefully with lid):p.
This would be my main complaint. I spend a lot of my life pursuing labor saving practices and devices that make my life easier to live and free up more time for the “better things”. Voluntarily adding a new chore cycle of poo-cloth storage, laundry separation, etc is not going to happen. You still have to hot-water wash and detergent the cloths anyway, so I fail to see the green benefit.
I think in this case it is more of a thought experiment than something actually meant to save the earth in a substantial way. I don’t think it’s worth a news story or anything, but it can be interesting to step back and think about how much we throw away, and what if any limits there are on what can be reused.
In the Peace Corps, I could go a month without filling a garbage can, and the town garbage pile was limited to burned out cooking pots, shredded flip flops and torn plastic bags. Everything else was repaired or reused. You could even get cracked gourds and cheap flip flops sewn up. It still amazed me that here, I often have to empty my garbage nightly, and it’s often full of uneaten food and superfluous packaging. I’m not on a soapbox about waste or saying the developing world is doing it better. But it’s not a bad thing to be a bit mindful of your life now and then.
to the folks who only uses toilet paper to clean up after you squeeze one out, try this: clean up with as much toilet paper as you want. when you’re done, clean again with a wet wipe - you’ll be surprised by how dirty the wet wipe will be. a hose to wash up is the cleaner way to go.
