“The “Simple Humus Toilet” is a concept for an easy to install, ‘do it yourself’ composting toilet. It is not meant to threaten the conventional flush toilet culture, rather represents an alternative for anyone who ‘lives close to nature’ and wants to use a simple and low cost toilet system. It is ideal for the garden or empty section, but could also be used in disaster situations such as earthquakes.

“We’re designing an ultra-low-cost toilet around removable containers that make it easy to collect and transport wastes safely from the community. We know from many conversations with residents of Shada that a good toilet is a symbol of cleanliness and modernity. Beyond being odorless, hygienic, and vector-free, our toilet needs to be elegant, modern, and pleasant to use. And it needs to be cheap. To that end, our toilet combines a 20-L bucket, a liquid container, and a western-style toilet seat into a sealed, portable, urine-diverting toilet.
