A single source for clean water and fuel

ALGAE are being put to work performing a unique double duty: cleaning up sewage waste while simultaneously producing biofuel.

All algae feast on phosphates and nitrogen-containing compounds, converting them to lipids. Some of these oils can be converted to biofuel, but only a few algal species produce lipids of the right type and quantity to be easily converted to fuel. In theory, though, algae are a perfect renewable fuel source. The main obstacle is that brewing the right nutrient mix can be prohibitively expensive.
