• (March 18, 2025) Agreement on Collaboration and Cooperation between Inagi City and ENEOS

Recycling of Household Used Cooking Oil

This is an initiative to recycle used cooking oil.

The waste cooking oil collected by mobile sales vehicles from Keio Store and Keio Corporation is processed to remove impurities by the partner collection company, Yoshikawa Yushi Co., Ltd., and is recycled into products such as soap and ink by business operators.

In the future, we also plan to recycle into Sustainable Aviation Fuel (SAF).

What is SAF

SAF (Sustainable Aviation Fuel) is aviation fuel produced from non-fossil materials such as used cooking oil and animal fats. Compared to fossil fuel-derived fuels, it can reduce the emissions of greenhouse gases, including CO2. ENEOS Corporation aims to supply household used cooking oil as part of the raw materials for SAF production plants in the future.
