Biotech researchers transform biodiesel waste into additional fuel
Ray Newkirk doesn’t hesitate to wash his hands with dirty soap. Before founding the Green Station on Ocean Street in Santa Cruz, where locals pump Bay-Area-made biodiesel into their cars, Newkirk was a backyard producer, making fuel out of fryer waste from the Saturn Café.
Like other biodiesel producers, Newkirk also inevitably made a lot of dark, thick waste glycerin.
For every 100 gallons of biodiesel made, 10 gallons of the crude goop remain. Last year 600 million gallons of biodiesel were produced, and while a freeze on tax credits has slowed production this year, America will still have millions of gallons of crude glycerol at its fingertips.
