We’re already harvesting methane from sewage and spreading treated sewage solids on farms and open space, so it’s not a stretch to imagine running our cars on biofuel from sewage, too. Specifically, running our cars on sewage grease. An enormous amount of grease enters our sewer systems - about 495 million gallons annually in the U.S. alone. Most of it gets captured and collected at sewage treatment plants. So what’s stopping us - the ick factor aside - from siphoning off this readily available and potentially valuable biofuel feedstock?
