Tree Bog

[pfafrich]

Best and simpest idea for a toilet I've seen is the tree bog. Its a raised platform over an enclosure space fenced off with chicken wire. Around the bog you plant willow or other greedy trees which rapidly consume the nutrients, effectively turning the poo into biomass. Aerobic decomposition has advantages over anaerobic decomposition and there is no smell if you use a layer of sawdust. The whole thing requires no maintenance as the poo decomposes very quickly. Not good for urban situations but ideal in rural environments.
