SeQuential Environmental Services, a used cooking oil (UCO) collector based in the U.S. Pacific Northwest, has merged with Neste-owned Mahoney Environmental to become Mahoney Environmental Services as of Jan. 1, according to a social-media post by Tyson Keever, chief operating officer.

SeQuential’s website states, “We are thrilled to share some exciting news that signifies a positive transformation for our company. In our ongoing commitment to deliver exceptional service and sustainable solutions, SeQuential is partnering with Mahoney Environmental. The change is more than just a collaboration and represents a milestone in our journey to enhance our services and expand our reach.”

Dave Kimball, president and CEO of Mahoney Environmental, also posted on social media that, “As we move in to the New Year, I’m excited to share some exciting news that signifies a positive transformation for Mahoney Environmental and SeQuential. On Jan. 1, we will become one company and most importantly, we will provide a seamless experience for our valued customers in our ongoing commitment to deliver exceptional service and sustainable solutions. This change represents a milestone in our journey to enhance our services and expand our coverage along the West Coast. With SeQuential, we’re recycling more used cooking oil into renewable fuels. Together, we are fighting climate change. I know this merger will propel our company to the next level, and it couldn’t be done without our amazing employees and customers.”

In 2018, SeQuential, then a vertically integrated Oregon-based biodiesel producer and UCO collector, was acquired by the California-based biodiesel manufacturer Crimson Renewable Energy.

In 2020, global renewable diesel and sustainable aviation fuel (SAF) producer Neste Corp. acquired U.S.-based Mahoney Environmental.

In November 2022, Neste announced it planned to acquire the UCO collection and aggregation business and related U.S. assets from Crimson Renewable Energy.

The transaction, which closed in January 2023, included shares in SeQuential Environmental Services and Pure LLC, as well as a UCO processing plant in Salem, Oregon.

That deal, however, did not include Crimson’s biodiesel production facility in Bakersfield, California.

Also in 2022, Neste and Marathon formed a joint venture involving the conversion of Marathon’s petroleum refinery in Martinez, California, for the production of up to 730 million gallons per year of renewable diesel and SAF.

Following the merger with Mahoney, SeQuential’s website states, “We appreciate your continued trust and partnership. Together, with Mahoney, we are transforming used cooking oil into low-carbon renewable diesel and sustainable aviation fuel. We are fighting climate change together. Thank you for being a part of our journey.”
