SeQuential

What SeQuential does

SeQuential is a renewable fuels and environmental services company that converts used cooking oil into renewable diesel and sustainable aviation fuel (SAF). Founded in 2002 and headquartered in Portland, Oregon, the company sits in the downstream segment of the UCO value chain, processing waste grease collected from commercial kitchens into drop-in biofuels. Operationally, it is tightly linked to Mahoney Environmental, which provides the upstream collection infrastructure serving over 90,000 food establishments across all 50 US states. Under CEO Harry Simpson, the company employs between 101 and 250 people.

SeQuential's product portfolio spans the full used cooking oil lifecycle. Core services include used cooking oil collection and recycling, professional grease trap cleaning, automated and standard oil container systems (including custom equipment design and installation), and fresh cooking oil delivery back to commercial kitchens. Its customer base is highly diversified across verticals: independent restaurants (the primary segment), grocery and convenience stores, hotels and resorts, casinos and country clubs, stadiums, schools, airports, and corporate and franchise national chains. The company does not disclose its core refining technology or proprietary IP, and its competitive edge is grounded in physical logistics scale rather than disclosed technological differentiation.

The business model combines recurring service revenue (UCO pickup, grease trap maintenance, fresh oil delivery, equipment leasing/installation) with commodity-linked revenue from biofuel refining. Customer acquisition is primarily direct, supported by content marketing (blog), an active social media presence across Facebook, YouTube, LinkedIn, and Instagram, and a customer referral program that leverages the 90,000-account base. The circular-economy narrative — converting kitchen waste into renewable transportation fuel — underpins SeQuential's positioning with sustainability-focused enterprise customers, though no AI/ML capabilities, patents, certifications, or formal partnerships were disclosed in the available sources.
