Sewage Biofuel Hits the Big Time with Waste Management Venture
Industry juggernaut Waste Management is convinced there’s a future in sewage-to-biofuel, and to prove it the company has just joined with the largest refiner in the U.S., Valero Energy Corp., to blend wastewater “crude” into gasoline. The two companies have invested in Terrabon LLC, which was formed in the 1990’s to commercialize three technologies including a biofuel process called MixAlco. With a half-billion people (and counting) contributing to the feedstock in the U.S. alone, it looks like sewage could be the answer to the search for a truly sustainable biofuel.
