Thanks, we had fun making it. I don't know how effective this would be as a large scale solution because a lot depends on the composting that follows the toilet filling up. To compost an entire settlements waste is a logistical challenge that needs regular maintenance. it would definitely be better than having no toilet, but this will definitely have to be adapted for that scenario. This is perfect for people living off grid who can dig and maintain their own compost pits. Mo' people mo' problems.
