Algae clean pollution, creating clean energy and fish food

ScienceDaily is ran a story featuring Johns Hopkins University (JHU) graduate students studying integrated systems to mitigate agricultural waste and produce algae biofuels.

Turning Algae Into Clean Energy and Fish Food; Helping Africans to Irrigate Crops

Could algae that feast on wastewater produce clean bio-fuels and a healthful supply of fish food? Can impoverished African community gardeners learn to use and maintain a simple centuries-old, non-electric water pump to grow more
vegetables?

The article discusses the 2013 National Sustainable Design Expo, occuring this week, on the National Mall in D.C, sponsored by the Environmental Protection Agency (EPA). The expo is part of a competition for follow-up grants to teams through a program entitled P3: People, Prosperity and Planet Student Design Competition for Sustainability.

One of the JHU teams, named AlgaFuture, developed a project to use algae in wastewater treatment facilities to remove agricultural run-off pollutants such as nitrogen and phosphorus. As the algae grow, they can reduce the level of polutants. The biomass can then be used to produce renewable biofuels.
