- A treebog is a type of low-tech compost toilet. It consists of a raised platform above a compost pile surrounded by densely planted willow trees or other nutrient-hungry vegetation. It can be considered an example of permaculture design, as it functions as a system for converting urine and feces to biomass, without the need to handle excreta. Defecating in nature is frowned upon in most countries, as it pollutes the environment and causes health problems. High levels of open defecation are linked to high child mortality, poor nutrition, poverty, and large disparities between the rich and the poor. Human faeces normally take about a year to biodegrade outdoors. In the UK, a system like this is potentially legal, so long as it not in a public place, i.e. on a large private estate. (en)
