Phillips 66 and Restaurant Technologies, Inc. (RTI) have formalized a significant long-term agreement aimed at bolstering the domestic supply chain for renewable fuels, specifically focusing on the conversion of used cooking oil (UCO) into Sustainable Aviation Fuel (SAF) and renewable diesel. This strategic collaboration leverages RTI’s extensive network of over 45,000 food service locations across the United States to provide high-quality, traceable feedstock to the Phillips 66 Rodeo Renewable Energy Complex in California. As one of the largest facilities of its kind globally, the Rodeo complex represents a cornerstone of the energy industry’s transition toward lower-carbon solutions. The partnership underscores a growing industrial trend where waste streams from the hospitality and food service sectors are repurposed to meet the rigorous energy demands of the aviation and transportation industries.
The Mechanics of the Strategic Feedstock Agreement
The agreement establishes a reliable pipeline of used cooking oil, a critical feedstock for the production of second-generation biofuels. RTI, a leader in automated cooking oil management, will supply Phillips 66 with UCO that is International Sustainability and Carbon Certification (ISCC) certified. This certification is a vital component of the deal, as it ensures the feedstock meets stringent global standards for greenhouse gas reduction, traceability, and environmental sustainability, aligning with the principles of the United Nations Global Compact.
According to Mark Hughes, Senior Vice President of Commercial at Phillips 66, the agreement is a strategic move to secure feedstock optionality. By locking in a consistent, domestic supply of high-quality oil, Phillips 66 can better manage the volatility of the renewable fuel market while ensuring its California operations remain at peak productivity. The integration of RTI’s collection capabilities with Phillips 66’s refining expertise creates a robust value chain that connects thousands of American kitchens directly to the fuel tanks of commercial aircraft.
Innovation in Collection: The Closed-Loop System
A primary driver of the efficiency of this partnership is RTI’s proprietary closed-loop automated cooking oil management system. Unlike traditional "open" collection methods—where used oil is often stored in outdoor bins susceptible to theft, contamination, and weather-related degradation—the RTI system manages the oil within a controlled, automated environment. This technology ensures that the UCO remains clean, separated from food waste, and largely free of excess water or other contaminants that typically complicate the refining process.
Ronald Cardwell, Director of Commodity Strategy at RTI, emphasizes that the quality of the final fuel is fundamentally tied to the quality of the initial feedstock. By maintaining purity at the source—the restaurant kitchen—RTI reduces the need for intensive pretreatment at the refinery. This increased efficiency allows for a higher conversion rate, meaning more of every gallon collected is successfully transformed into usable, high-performance renewable fuel. This systematic approach to waste management effectively turns a logistical challenge for restaurants into a high-value asset for the energy sector.
The Transformation Process at the Rodeo Renewable Energy Complex
The journey from a deep fryer to a jet engine involves complex chemical engineering at the Phillips 66 Rodeo Renewable Energy Complex. Once the UCO is collected from RTI’s network—which spans 41 markets and includes hotels, casinos, colleges, and restaurants—it is transported to the California facility. The transformation process begins with a rigorous cleaning phase to remove any remaining microscopic impurities.
Following pretreatment, the oil is heated and subjected to a process known as hydroprocessing. During this stage, the feedstock is combined with hydrogen under high pressure and temperature in the presence of catalysts. This chemical reaction removes oxygen and rearranges the hydrogen and carbon atoms into hydrocarbons that are identical to those found in conventional petroleum-based fuels. The resulting "neat" (unblended) SAF is then blended with traditional jet fuel to meet ASTM International standards, ensuring it is a "drop-in" fuel that requires no modifications to existing aircraft engines or airport infrastructure.
Environmental and Economic Impact of SAF
The adoption of Sustainable Aviation Fuel is widely regarded as the most effective near-term solution for decarbonizing the aviation industry, which is responsible for approximately 2-3% of global carbon dioxide emissions. According to industry data, SAF can reduce lifecycle greenhouse gas (GHG) emissions by as much as 80% compared to conventional fossil-based jet fuel. These reductions are calculated by considering the carbon absorbed by the organic feedstocks during their growth or the emissions avoided by diverting waste from landfills.
For airlines and corporate flight departments, the availability of SAF is crucial for meeting increasingly stringent ESG (Environmental, Social, and Governance) goals. The Phillips 66 Aviation team facilitates the sale of this renewable fuel to customers who require certified emissions reporting to prove their progress toward net-zero targets. Furthermore, the diversification of the fuel supply through SAF enhances energy security. By utilizing domestic waste products rather than relying solely on global crude oil markets, the aviation industry can build a more resilient energy profile.
Chronology of the Rodeo Facility Transition
The partnership with RTI is a pivotal chapter in the broader history of the Phillips 66 Rodeo facility. Originally a traditional crude oil refinery, the site has undergone a massive multi-year transformation known as the "Rodeo Renewed" project.
- Initial Announcement: Phillips 66 first announced plans to convert the San Francisco-area refinery into a renewable fuels plant in 2020, citing the shifting regulatory landscape in California and the rising demand for low-carbon fuels.
- Permitting and Construction: Over the subsequent years, the company navigated complex environmental reviews and transitioned its processing units to handle bio-based feedstocks rather than heavy crude.
- Operational Milestone: In early 2024, the facility reached a major milestone by commencing the commercial production of renewable diesel and SAF.
- Supply Integration: The current long-term agreement with RTI represents the stabilization phase of the project, where the company is securing the massive volumes of feedstock required to operate at full capacity.
The facility now has the capability to produce approximately 800 million gallons of renewable fuels per year, making it a global leader in the transition to renewable energy.
Supporting Data: The Rising Demand for Bio-Feedstocks
The global demand for renewable feedstocks is projected to grow exponentially over the next decade. Market analysis suggests that as more countries implement Low Carbon Fuel Standards (LCFS) similar to California’s, the competition for high-quality waste oils will intensify.
- Feedstock Availability: While vegetable oils like soybean and canola are common, waste-based lipids like UCO are preferred because they do not compete with food crops for land use, giving them a lower carbon intensity score.
- Aviation Targets: The International Air Transport Association (IATA) has set a goal for the aviation industry to achieve net-zero carbon emissions by 2050. Achieving this will require SAF to account for roughly 65% of all aviation fuel used by that date.
- Regulatory Incentives: The U.S. Inflation Reduction Act (IRA) provides significant tax credits for the production of SAF, further incentivizing energy companies like Phillips 66 to invest in large-scale conversion projects and secure long-term feedstock contracts.
Industry Reactions and Strategic Implications
The partnership has been met with positive sentiment from both the energy and hospitality sectors. Industry analysts note that this agreement provides a blueprint for how "circular economy" principles can be applied on an industrial scale. By providing a guaranteed market for used cooking oil, Phillips 66 gives food service operators an incentive to participate in sustainable waste management practices.
For Restaurant Technologies, the deal validates their investment in closed-loop infrastructure. It moves the company from being a service provider to a critical player in the global energy transition. For Phillips 66, the deal mitigates one of the greatest risks in the renewable fuel sector: feedstock scarcity. As more refineries convert to renewable production, the "battle for the barrel" has shifted from crude oil to used cooking oil and animal fats.
Future Outlook: Scaling the Lower-Carbon Flight
As the Rodeo Renewable Energy Complex continues to scale its operations, the impact of the Phillips 66 and RTI agreement will be felt across the aviation sector. Airlines are currently facing a "supply gap" where the demand for SAF far outstrips the available supply. Agreements that secure feedstock and streamline production are essential for narrowing this gap and making lower-carbon flight more accessible and affordable for the general public.
The long-term nature of this agreement signals to the market that the infrastructure for a renewable energy future is not just a concept, but a functioning reality. As Ronald Cardwell noted, the pieces are now in place to scale these operations. The success of the Rodeo facility, supported by the steady supply from RTI’s 45,000+ locations, serves as a proof of concept for other regions and industries looking to bridge the gap between traditional operations and a sustainable future.
In conclusion, the collaboration between Phillips 66 and Restaurant Technologies represents a sophisticated integration of logistics, technology, and chemistry. By looking to the "deep fryer" as a source of energy, these companies are demonstrating that the path to energy security and carbon reduction often begins with the most common waste products of modern life. As SAF production continues to ramp up, the role of reliable, high-quality feedstock will remain the linchpin of the aviation industry’s journey toward a net-zero horizon.
