Our History

In many ways, our company was born in the same place our products begin: the back of a restaurant. Mazzi’s Italian eatery, to be exact—the Eugene, Oregon pizza shop where Ian Hill and Tyson Keever first met in 2001. The pair shared a passion for the environment and quickly struck up a friendship over a love for the outdoors and a firm belief that there had to be a better way to create energy without harming the planet. SeQuential was formed a year later.

Early on, we sold homemade biodiesel by the barrel from a pickup truck. After thousands of miles on the road and hundreds of relationships forged, we now collect millions of used cooking oil each year that is transformed into renewables. And we’ve replicated our model across the nation – collecting and recycling used cooking oil.


As of 2023, we now work with the global company, Neste, to create renewable fuels and continue our mission to work towards a more sustainable world.

Strong partnerships have always been a part of our DNA to take our mission to build a better energy model to a new level. We are one of only a handful companies in the U.S. handling on a large-scale the process from beginning to end: collecting used cooking oil, refining it into renewable fuels and refueling vehicles, fleets, and fuel stations in our communities.
