Cosmo Oil Co., Ltd., in collaboration with Suita City, Osaka Prefecture, JGC Holdings Corporation, REVO International Inc., and SAFFAIRE SKY ENERGY LLC, has signed an agreement to promote Sustainable Aviation Fuel (SAF). The agreement, effective from March 12, 2025, outlines a cooperative effort to convert used cooking oil into SAF feedstock, advancing environmental sustainability.

The "Agreement on Collaboration and Cooperation in Promoting the Adoption of SAF" aims to encourage the collection and recycling of used cooking oil into SAF. A signing ceremony was held on the same day at Cosmo Oil's Sakai Refinery, Japan's first major SAF production facility.

Suita City will supply around 27,000 liters of used cooking oil annually for this initiative—the largest contribution of its kind from a Japanese municipality. As part of Suita City's General Waste Management Plan, the city has actively supported accessible recycling systems. Since 2009, Suita has installed collection points for used cooking oil at public facilities, facilitating proper disposal and reuse. While this resource can become valuable SAF feedstock, many households still discard it as waste. Through this partnership, Suita City will expand collection efforts to convert waste oil into aviation fuel, empowering citizens to contribute to a carbon-free, resource-recycling society.

The five collaborating organizations will work together to build a sustainable and decarbonized society by:

• Collecting household-generated used cooking oil.
• Supporting production and continued SAF supply.
• Raising public awareness about recycling used cooking oil into SAF.
• Expanding oil collection points across Suita City.
• Developing additional initiatives aligned with the Agreement's objectives.

Key Initiatives:

Used cooking oil collected from 15 public facilities, including city offices and libraries, will be transported by REVO International to the SAFFAIRE SKY ENERGY plant located at Cosmo Oil's Sakai Refinery. This facility, completed in December 2024, will lead Japan's large-scale SAF production efforts by converting recycled cooking oil into sustainable fuel. Additionally, oil from 35 municipal elementary schools and 14 public daycare centers will be collected for SAF production, bringing the annual total to approximately 27,000 liters.

To further encourage participation, Cosmo Oil's service stations in Suita City may also become collection points. To promote awareness, citizens who donate used cooking oil will be entered into a lottery featuring prizes like "Suitan Goods" (the city's mascot-themed items) and SAF facility tour invitations. The initiative will also extend awareness campaigns to local businesses to boost engagement and promote sustainable practices.
