Phillips 66 and Restaurant Technologies are Converting Used Cooking Oil into Sustainable Aviation Fuel
Phillips 66 and Restaurant Technologies (RTI) have a long-term agreement to convert used cooking oil from U.S. restaurants into sustainable aviation fuel (SAF) at Phillips 66's California facility. RTI supplies ISCC-certified used cooking oil, while Phillips 66 produces and sells SAF, reducing greenhouse gas emissions by up to 80%. The partnership aims to strengthen supply for lower carbon fuel markets and support decarbonization commitments.
How this was made

The 30-second read
Why it matters
The key trading angle is improved feedstock reliability and quality for SAF production, which can reduce operational friction and support renewable fuel output, but the lack of financial terms limits near-term earnings impact assessment.
Market read
A long-term, traceable used cooking oil supply agreement links RTI’s feedstock quality to Phillips 66’s SAF production, supporting the renewable aviation fuel supply narrative.
What to watch
SAF economics depend on policy incentives, hydrogen and processing costs, and certification demand; the article does not address these sensitivities or potential feedstock competition.
Background
The article describes a closed-loop used cooking oil collection and processing approach by RTI and its integration with Phillips 66’s Rodeo Renewable Energy Complex to produce certified SAF.
Ticker impact
Phillips 66 is named as the SAF producer at its Rodeo Renewable Energy Complex, supplied with ISCC-certified used cooking oil under a long-term agreement.
Likely modest positive bias as investors price improved renewable-fuels supply optionality and integration benefits.
The article is a specific long-term supply agreement tied to Phillips 66’s named facility, but it provides no financial terms or capacity numbers to gauge magnitude.
Market effects
Reinforces the renewable fuels value chain theme, highlighting feedstock quality and traceability as differentiators for SAF supply.
California-based Rodeo Renewable Energy Complex is positioned as a key SAF production hub supported by domestic restaurant feedstock.
Supports lower-carbon aviation fuel supply narratives tied to lifecycle GHG reductions and certification frameworks used in emissions reporting.
Counterpoint
Without disclosed volumes, pricing, or contract economics, the market may treat this as incremental rather than materially earnings-moving.
