Throughout history, wherever there was a major population of humans, there was also a problem of sanitation. Some of our largest urban areas today cope with this same difficulty only now we must consider how human sanitation will affect the environment and the world.

A team at Oregon State University, headed by Hong Liu, associate professor for biological and ecological engineering, may have a solution to resolve this dilemma Liu and his team have created a fuel cell that uses a microbial mixture for wastewater cleaning and at the same time creates it’s own energy.

While this fuel cell is still in its infancy, the possibilities of use could prove to be an answer by replacing and adding to a more efficient technology to some of the world’s largest wastewater facilities.
