Indonesian petrochemicals and energy firm Chandra Asri has signed an agreement with sovereign wealth funds Danantara and the Indonesia Investment Authority to jointly develop a chlor-alkali ethylene dichloride (CA-EDC) plant in Cilegon city, Banten.
Danantara and INA will jointly invest about $800mn in the project. The plant aims to boost Indonesia's production of caustic soda and EDC to strengthen industrial downstream self-sufficiency and reduce import dependency of inputs for industries such as water treatment, soap and detergent manufacturing, alumina refining and nickel processing.
In a first phase, Chandra Asri will build a plant with a production capacity of 400,000 t/yr of solid caustic soda (equivalent to 827,000 t/yr in liquid form) and 500,000 t/yr of EDC. A potential second phase could expand production and introduce chlorine derivatives, depending on the outcome of ongoing feasibility studies.
"The chemical sector underpins key value chains — from manufacturing to energy transition — especially in nickel processing and alumina refining," Danantara chief investment officer Pandu Sjahrir said. "This investment strengthens national resilience by reducing import dependence on essential products like caustic soda and EDC," he added.
The joint venture is expected to generate EDC export earnings of up to 5 trillion rupiah/yr ($306mn) and trim Indonesia's import bill for caustic soda by Rp4.9 trillion/yr.
