About SeQuential

Our company’s roots trace back to Mazzi’s Italian eatery in Eugene, Oregon. It was there, in 2001, that Ian Hill and Tyson Keever crossed paths and ignited a shared vision for a greener future. Bonding over their love for the environment and the great outdoors, they recognized the pressing need for a sustainable approach to energy generation. In 2002, SeQuential was born, and has since been acquired by Mahoney on 01/01/2024.

In the early days, we sold homemade biodiesel from the back of a pickup truck, one barrel at a time. As we traveled countless miles and fostered meaningful connections, our dedication grew stronger. Today, we proudly collect millions of gallons of used cooking oil annually, transforming it into renewable fuels. Our model has expanded nationwide, allowing us to make a significant impact in the collection and recycling of used cooking oil.

From humble beginnings to a nationwide endeavor, Mahoney (formerly SeQuential) remains committed to our mission of environmental stewardship and sustainability.

In 2023, we proudly joined forces with the global powerhouse, Neste, to propel our mission of fostering a more sustainable world to new heights. This partnership amplifies our commitment to creating renewable fuels and driving positive change.

At Mahoney (formerly SeQuential), collaboration has always been ingrained in our DNA as we strive to revolutionize the energy landscape. We stand among a select few companies in the United States that handle the entire process on a large scale – from collecting used cooking oil, refining it into high-quality renewable fuels, to refueling vehicles, fleets, and fuel stations within our communities.

By seamlessly integrating each step, we deliver a comprehensive solution that sets us apart. It’s through these strong partnerships and our unwavering dedication that we’re able to create a better energy model, advancing sustainability on a grand scale. Join us in shaping a brighter future for generations to come.
