About Us
Vashon Bioenergy Farm, LLC (VBF) is a community-scale bioenergy system on Vashon, at Island Spring Organics. For every 60 to 80 pounds of “waste” that would otherwise be hauled away, Impact Bioenergy’s NAUTILUS generates about 7 gallons of organic plant food and 1 gasoline gallon equivalent of ultra low carbon renewable fuel.

VBF helps to reclaim and regenerate over 2,000 pounds of nutrients and 300,000 gallons of water annually, along with plenty of clean energy to help power a resilient circular economy, on-island!
