Engineering for Change

Interest: Sanitation

About one in three people worldwide don’t have access to improved sanitation, but managing waste could solve a lot of the world’s health problems. For all of its importance, the issue still gets little attention. We have the solutions. Good, low-cost latrines have been built worldwide, latrines that do not require an expensive sewage system because they compost waste to convert it into safe fertilizer. The toilets of the world’s future might look reminiscent of the toilets of the past, and that’s a testament to user-centered design.
