This Demonstration Project is being conducted based on the demonstration plan announced by the Three Companies in March 2025, aimed at achieving a carbon-recycling society.

JFE Steel has commenced the supply of by-product gas generated from its steelmaking processes for the Demonstration Project. Mitsubishi Gas Chemical has begun producing methanol using this by-product gas at its newly constructed Carbopath^™*1 demonstration plant within its Mizushima Plant. Furthermore, Mitsubishi Chemical has begun producing propylene using this methanol as raw material at its existing demonstration facility (utilizing the DTP^®*2 process).

The Three Companies will continue the Demonstration Project, evaluate its economic viability, and identify challenges and pathways toward commercialization. Furthermore, the Three Companies will explore broader opportunities for collaboration with other businesses within the Mizushima Complex.
