Key Ideas

01

The Humanure Handbook promotes ecological sanitation to combat global "shit illiteracy."

Years ago, a graduate thesis explored the topic of composting toilets. Its author, who lived off the grid and used a homemade compost toilet for fifteen years, delved deeply into the subject for academic purposes. He decided to self-publish his thesis under the title "The Humanure Handbook" as a learning exercise in publishing. Despite his initial belief that there would be little interest, the first edition sold 10,000 copies, leading to multiple updated editions and translations in over a dozen languages. Over the course of forty years, the author continuously refined his composting methods. During this time, he recognized a societal issue he called "shit illiteracy." This term describes how modern water-based toilets hinder people's understanding of recycling organic materials, causing a developmental gap in sanitation practices. Through his extensive travels, he observed that the majority of the world's population lacks access to flush toilets. Instead, they face significant issues related to open defecation and inadequate sanitation. The author seeks to share his four decades of experience through this edition and an upcoming companion volume. His primary goal is to educate people about ecological sanitation, offering practical solutions for a cleaner, more sustainable future.
