New Hampshire Company Aims To Make Biofuel From Sewage

Reduce. Reuse. Recycle. Those are core tenets of the green movement. Most commonly, that means recycling glass bottles or newspapers, or shredding old tires to make the fill for playgrounds.
What about sewage? Wouldn’t it be great if we could do something with sewage? It’s essentially an infinite resource—as long as there are people, there will be sewage—and at present, it’s “waste” in all senses of the word; there’s nothing valuable or productive being done with it.
Until now (maybe). A New Hampshire company, Simply Green Biofuels, hopes to use sewage as the feedstock for oil-producing algae. As our Jennifer Schwatz has written, algae are a promising source for biofuel: high-yield, fast-growing, carbon-neutral, don’t tie up productive farmland, and can thrive almost anywhere—including on sewage. In fact, sewage plants already have algae; the trick is to grow the right kind and then harvest and process the algae economically, which admittedly is a trick no one has quite figured out yet. (Though several companies and researchers are getting close.)
Simply Green currently repurposes waste vegetable oil from restaurants into biodiesel. Processing oil-producing algae into fuel is just an extension of what they already do, which is why they have partnered with Clean Power Development to build an algae farm that they hope will be fed by sewage from the Berlin wastewater treatment facility.
Biodiesel is also a flexible fuel, inasmuch as diesel fuel and home heating oil are chemically identical. Biodiesel can be used, depending on how it’s blended, to heat your home or drive your car or truck. And its net carbon emissions could be zero. If we can produce biodiesel using a never-ending, otherwise worthless waste, that’s a blow for energy independence and the environment.
