Compost Toilet


Joseph Jenkins, The Humanure Handbook

The design for a safe, user-friendly, ecological, odor free toilet that does not require water, electricity, drains, pumps, vents, chemicals or much money, and which actually recycles a resource to create something of value, came from years of living without electricity or running water on a very low budget. In fact, billions of people today live without electricity, running water, or much money, and they need toilets too.

What it does

Composting toilets, and the habits to maintain them, are an essential solution to the world’s water and sanitation challenges. Using a compost toilet at home saves water, re-uses agricultural waste, eliminates bacteria and coliforms, and builds soil fertility for farming.

The Humanure Handbook, by Joseph Jenkins, describes the structural designs and techniques to manage odor-free composting toilets in varying conditions worldwide.   Whether one lives in a USA suburb or on sub-Saharan farmland, readers learn to manage composting toilet systems and turn waste into resource. 

Humanure addresses cultural taboos around human waste and questions the viability of using a scarce resource - fresh water - to provide billions of people with sanitation.   Shifting our society to use compost toilets can help us regenerate from our current environmental and poverty crises.
