Toilets, Episode 1

A toilet is a petty simple device. It simply collects waste and sends it along for processing, in a hygienic and efficient way. We all take toilets for granted (those of us in the first world, at least).

But when you're in a situation where you have to provide for your own waste, then you don't take waste handling for granted at all.

On Aspö, most homes have some sort of composting toilet system. Liquid waste is drained away from the home into the earth, and solid waste is kept and composted. A bit of mulch, a few microbes, a bit of stirring, careful ventilation, and solid waste becomes harmless over time. However, new rules regarding composting are about to come into force. This composting regime will take more steps and more time before solid waste can be disposed of.

Spending extra time and work on handling solid waste isn't my cup of tea. So I decided to concentrate on the non-composting toilets at the expo.
