New Method of Turning Sewage Sludge into Biodiesel is Low-Cost, High-Yield | Sustain Our Earth |

I have a love/hate affair with biofuels and biodiesel, because while they may be cleaner than petro-fuels, and considered a renewable resource, growing the feedstock usually entails a lot of land and a lot of water, both of which are limited resources. But if a new process for making biodiesel from sewage sludge gets commercialized, every flush of the toilet could be helping to fuel some of our energy needs.
