Professors from the University of Missouri and Duke University have been working to design self-sustaining toilets.  While this may not seem like a need in counties with developed sewer system, in places without sewer networks dealing with human waste can be a serious health problem. According to the World Health Organization, 2.4 billion people do not have access to any type of improved sanitation facility and roughly 2 million people die every year due to diarrhoeal diseases, most of them younger than 5 years old.
