Refinement

We’re the longest-running commercial biodiesel producer on the West Coast.

For more than a decade, we’ve refined oil at our centrally located production plant in Salem, Oregon. Our proven, certified process turns used oil into sustainable products, including biodiesel, glycerin, salt cake, and boiler fuel.

What doesn’t get turned into a bioproduct is put back into the system, helping us keep our process and refinery producing nearly zero waste. We employ on-site R&D and equipment fabrication to expand capacity and yield, save energy, reduce waste, create new markets, and put existing products to new use—just a few of the many ways we’re always looking to innovate.
