Far-future research dialogue by Philips Design

A waste separating squatting toilet that filters effluent while channelling excreta to a methane digester in the Microbial Home system.

The squatting toilet incorporates a handrail to support a person (and improve comfort)  in the squatting position. The filter array, comprised of charcoal, sand and ceramic filters, supports a range of plants to clean effluent. The flush mechanism is based on the 1 litre flush toilet technique developed by the Sulabh Foundation in India.

The concept is sustainable and ecological. It uses no energy, is water saving and non polluting.
The system is designed to show the energy value in human waste and raise awareness about wasting water. It provokes discussion and evaluation of toilet taboos and ablution habits. It draws attention to the necessary systemic shift from utility dependent sanitation systems to regenerative localized solutions that see waste as a necessary part of a domestic eco-system.

There are both health and ergonomic benefits to using the squatting toilet. Evidence shows that there are significantly fewer cases of colorectal cancers in communities that squat as opposed to those using sitting toilets. Squatting ensures a natural position for the human bowel movement and minimizes the need for toilet tissue which has a detrimental health effect.

how do you make one?

The apparent claim that squatting has a causative relationship to decreased colorectal cancer seems dubious at best.  Remember that correlation does not equal causation.  Most places where squatting toilets are the norm have significantly different dietary and exercise habits compared to the "West" where sitting toilets are the norm.  These places tend to eat a much more varied diet, with a greater proportion of their diet consisting of plants and unprocessed foods.
