Itochu Enex Co., Ltd.
Obayashi Corporation
Itochu Enex Co., Ltd. and Obayashi Corporation will conduct a demonstration experiment using renewable diesel (RD *1) as fuel for construction machinery to be operated during construction work at Expo 2025 Osaka, Kansai, Japan (hereinafter referred to as "Osaka-Kansai Expo"),.
In this experiment, RD will be used as an alternative fuel to diesel oil for construction machinery (forklifts) that Nishio Rent All Co., Ltd. lease to Obayashi (planned RD usage volume : 1,800L, planned CO2 reduction : 4.6t). The RD will be procured by Itochu Corporation from Neste, a Finnish company, and supplied to Obayashi by Itochu Enex. Itochu Enex and Obayashi will investigate the impact of long-term use of RD on construction machinery during the construction period of the Osaka-Kansai Expo, as well as verify and optimize the process from fuel procurement to supply and use.
In addition to expanding the use of RD through this experiment, Obayashi will also conduct a demonstration experiment to use 100% biodiesel fuel (B100 fuel), which has a different manufacturing process and properties from RD, for construction machinery. Also, besides low carbonization of fuels, the company will promote various initiatives, including the introduction of electric construction machinery, the use of renewable energy, the promotion and expansion of ZEB, and the development and commercialization of low-carbon construction materials, thereby contributing to the realization of a decarbonized society.
Based on Corporate Philosophy of "The Best Partner for Life and Society," Itochu Enex will continue to contribute to a sustainable society by providing a stable supply of energy as an energy company and by promoting the use of products and services that reduce environmental impact.

- *1 Renewable Diesel (RD)
Neste MY Renewable Diesel is a next-generation biofuel produced by Neste, one of the world's largest manufacturers of renewable fuels (headquartered in Finland), from raw materials such as waste cooking oil and waste animal and vegetable oil that are not in competition with food, through a hydrogenation and refining process. It can be used as-is in vehicles and heavy machinery that use diesel fuel, and has achieved a 90% reduction in GHG (Greenhouse Gas) emissions on a life cycle assessment basis, compared to petroleum-derived diesel fuel.
