The Tree-bog compost toilet takes its name from the fact that human compost, or 'humanure', is a great fertiliser for trees and therefore not surprisingly trees growing close to composting toilets are particularly vigorous.
Unlike a conventional compost toilet, a tree bog should never need emptying. Effectively, it is a system for converting human fæces to biomass. The tree bog combines resource production and waste disposal and functions by transforming fæces and urine into growing trees and organic soil.
A beautiful, waterless compost loo, that helps trees to grow too!
