“People all over the world aspire to have water closets,” says Håkan Jönsson at the Department of Biometry and Engineering, Swedish University of Agricultural Sciences. “A WC brings status.”

“But with ecological sanitation they would have not only a good toilet but also good fertilizer that can make them money by increasing their yield. What’s more, it’s good for the environment.”

Ecological sanitation means separating urine and feces and using them as fertilizer after removing contagious substances. The result is a functioning closed nutritional cycle. What’s more, this saves water, since the amounts used are minimized and it is less polluted.
