Japanese chemical companies Asahi Kasei, Mitsui Chemicals, and Mitsubishi Chemical have set 2030 as their target for the potential reduction in ethylene output capacities in west Japan, the companies announced today.

The three firms have launched a limited liability partnership (LLP) Setouchi Ethylene LLP on 19 August. It will study potential output capacity reductions and carbon neutrality of their two ethylene production facilities in west Japan by 2030, they said.

Asahi Kasei and Mitsubishi Chemical have a 567,000 t/yr naphtha-fed ethylene cracker in the Okayama prefecture, and Mitsui Chemicals has a 500,000 t/yr naphtha-fed ethylene cracker in the Osaka prefecture, both in west Japan.

The partnership will also discuss whether the companies will scrap one of the two crackers or downsize their production capacities, a company spokesperson told Argus.

Each of the three companies has provided ¥500,000 ($3,400) to make a total capital of ¥1.5mn for the partnership. The firms are considering jointly operating the ethylene production facilities in west Japan as part of capacity optimisation plans by 2030, and the partnership will explore an ideal model for their joint operating entity.

The three companies previously announced in May 2024 plans to co-operate on the decarbonisation of the two ethylene production facilities. The firms considered introducing biomass feedstocks such as biomass-based naphtha, which the newly established LLP will discuss as part of their decarbonisation initiatives.

Japanese ethylene producers have been facing challenges because of weakening domestic demand and China's production capacity expansions. This has prompted them to consider restructuring their business.

Japanese energy company Cosmo Energy has decided to scrap subsidiary Maruzen Petrochemical's cracker in east Japan's Chiba prefecture in the April 2026-March 2027 fiscal year.

Fellow refiner Eneos is also considering decommissioning one of the two crackers at its Kawasaki refinery near Tokyo by the end of the April 2027-March 2028 fiscal year.

Mitsui Chemicals and refiner Idemitsu are also consider scrapping Idemitsu's cracker in Chiba by the 2027-28 fiscal year.
