Basic Chemicals

We will introduce what Basic Chemicals are, along with our production capacity, bases, and manufacturing flow.

Aiming to reduce the carbon content of plastic raw materials, we are working to supply biomass chemicals and build a supply chain for biomass plastics.

We aim to build Resources circulation system in which used plastics are recycled by heating and breaking them down into a refined oil equivalent to crude oil (oilification).

This is a joint venture between Mitsui Chemicals Co., Ltd. and Idemitsu Kosan. We manufacture, process, and sell polypropylene resin and polyethylene resin, and aim to create diverse and high value-added new products and technologies.

This is a joint venture between Asahi Kasei Corporation and Idemitsu Kosan. As Japan's largest polystyrene resin manufacturer, we manufacture, sell, and conduct research and development of synthetic resins.

Established in 1972, it is a wholly owned subsidiary of Idemitsu Kosan. As Malaysia's only polystyrene manufacturer, we manufacture polystyrene resin and sell it to Southeast Asia, including Malaysia.

This is a joint venture between Idemitsu Kosan and Environmental Energy Co., Ltd. We sell recycled oil made from used plastics and contribute to the circulation of plastic Resources through chemical recycling.
