This business strategy highlights the important contribution of chemical production to global sustainability. For instance, in April 2022, Hanwha Solutions made a strategic decision to increase its production of caustic soda. Caustic soda, or sodium hydroxide, is essential in the production of rechargeable batteries and lightweight materials, as they are both fundamental to building sustainable solutions. Hanwha Solutions invested $282 million (KRW 338 billion) to increase the production of caustic soda by an additional 270,000 tons. With this infusion of capital, the annual caustic soda production volume is expected to jump to 1.1 million tons by 2025.
