We provide used cooking oil collection and grease interceptor cleaning services all along the west coast. By converting used cooking oil into biodiesel, we reduce America’s dependence on foreign oil. Ultra-clean biodiesel produces up to 85% less carbon dioxide and 99% less sulfur dioxide than petroleum diesel which reduces the negative health impact from tailpipe emissions.

SeQuential is a subsidiary of Crimson Renewable Energy, the largest ultra-low carbon biodiesel producer on the West Coast, and one of the only companies in America handling the biodiesel production process from beginning to end: collecting used cooking oil, refining it into biodiesel, and refueling vehicles, fleets, fuel stations, and our local communities.
