The expansion projects involve investment of Rs 3,500 crore for augmenting the existing capacities of caustic soda, chloromethane, and phosphoric acid, besides caustic potash at its Dahej plant.
The caustic soda capacity is being expanded by 1,200 tonne per day (TPD), that of chloromethane by 600 TPD, phosphoric acid by 300 TPD and the caustic potash to 120 TPD, a company statement said.
The company is looking at setting up a 120 MW coal-based power project at Dahej as part of the expansion plan.
Alternatively the company may also acquire an existing caustic soda manufacturing plant with a similar capacity in Eastern part of the country, the release added.
