Audit Confirms Plant’s Commitment to Sustainably Produced Renewable Fuel

Salem, OR – March 16, 2017 – The Sustainable Biodiesel Alliance has announced the certification of SeQuential, the longest-running commercial biodiesel producer on the west coast, for its innovative and nearly zero-waste production of renewable fuel.

The SBA has developed and implemented an objective certification standard for measuring the sustainability of biodiesel production and use. SeQuential has been awarded via independent third-party audit score, the Gold level standard for biodiesel production.

SeQuential is dedicated to building a better energy model focused around regionally sourced biodiesel. All of the fuel SeQuential produces is made from used cooking oil recycled from restaurants and businesses within a roughly 500-mile radius of its Salem, Oregon, plant. Additionally, the company fuels its collection and delivery vehicles with high blends of its own biodiesel and offsets its energy consumption by using solar panels and setting regular energy conservation targets.

“The Gold Certified level is currently the highest standard achieved for sustainable biodiesel production,” said Jeff Plowman Vice-Chair of the SBA and Certification Committee Chair.

The audit checklist for biodiesel production is based on the SBA’s Baseline Practices for Sustainability, and evaluates the following:

  • Air Emissions
  • Water Resources
  • Waste Handling
  • Plant Energy
  • Sustainable Sourcing
  • Community Benefit
  • Plant/Worker Benefit
  • Quality

“We’re thrilled to be receiving SBA Gold Certification,” said Tyson Keever, CEO at SeQuential. “It’s rewarding to see our team’s commitment to sustainability recognized. We look forward to continuing to strengthen our sustainability practices through ongoing partnership with the SBA.”

This audit of SeQuential biodiesel production, the second of its kind, has given the SBA Certification Committee some valuable insight to the success of the audit procedure. The Committee is dedicated to an ongoing analysis of sustainable practices in biodiesel production, distribution and use of biodiesel and is looking forward to a procedural review this year.

About the Sustainable Biodiesel Alliance:

The Sustainable Biodiesel Alliance (SBA) is a 501(c) 3 non-profit organization created to promote sustainable biodiesel practices, including the harvesting, production and distribution of biodiesel fuels. These efforts include Environmental, Social and Economic sustainability. When biodiesel advocates Kelly King, Annie Nelson and Daryl Hannah formed the alliance in 2006, their ultimate goal was to create a certification system for verifying that all points in the production and distribution of the fuel are sustainable. This certification system, officially launched in 2016, will not only provide transparency for the consumer but also build extra value for a sustainable product. Since its creation, the Alliance has grown to include family farmers and farm organizations such as the Institute for Agriculture Trade and Policy (IATP), members of the 25 x 25 coalition, environmental organizations, renewable energy experts and a wide array of NGO’s.

About SeQuential:

Commercially operating since 2005, SeQuential is the longest-running biodiesel producer on the West Coast, and one of only a few domestic manufacturers that handle the entire production process from beginning to end: collecting used cooking oil, refining it into biodiesel and distributing it back into the local community.
