This book is about one of the biggest global challenges to human communities the handling and treatment of faecal waste, which also happens to be a topic many people find repugnant. With this book, premiering at the FSM4 Conference 2017 in Chennai, India, we want to bring you into our project work in India, Southeast Asia, Africa and Latin America. You’ll see not only the FSM process and technology, but also the people involved and the local people who benefit.
