I stumbled upon an interesting set of instructions for something that reuses a bucket, a toilet seat, a milk crate, scrap wood, and zip ties and makes a toilet that will recycle yet again.
All joking aside, this could come in really handy in a backcountry basecamp situation, or any other situation when you are not able to use all those luxuries, like water or pit toilets. It could certainly be more sanitary during an extended power outage than a non-functioning flush toilet (hurricanes, tornadoes, blizzard, alien invasion). It’s also a first step for people who want to lessen their impact on the environment.
