We're SeQuential.

We collect used cooking oil, refine it into biodiesel and bioproducts, and then refuel our communities. You might have seen our trucks on the highway, or spotted our used collection bins behind your favorite restaurant. Or maybe you have even filled your vehicle with our biodiesel. So is Sequential a cooking oil recycler? A trucking company? A biodiesel refinery? We’re all those things. We collect used cooking oil, refine it into biodiesel and bioproducts, and then refuel our communities. We take part in each step of the process. That’s why we are called SeQuential. We ensure each step is top-notch and always driving toward our main goal: to build a better energy model that puts people, community, and the environment first. It’s a simple idea, really, but one that’s better for us all. And, thankfully, there’s a place for everyone within our process. We hope you’ll join us. our origins “We began selling SeQuential biodiesel by the five-gallon jug.” Since our humble beginnings in 2002, we’ve built our own refinery, created more than 25 million gallons of biodiesel, and now operate up and down the West Coast. Thanks to relationships with partners such as Pacific Biodiesel and Tyree Oil, and customers like Kettle Foods and Burgerville, we’ve become what we are today—an innovative, conscientious maker of local, responsible bioproducts that’s helping build a better energy model for the future.

SeQuential Salem Processing Plant

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.
