Birla Corporation is planning to increase cement production capacity to 15 million tonne (mt) in the next four years from its current capacity of 9.3 million tonne. With the increase in production capacity, Birla Corporation would be among the top 10 cement producers in the country. The company which had signed an MoU with Assam Mineral Development Corporation (AMDC) for setting up a plant there, is waiting for the state agency to get the limestone mining lease after which a joint venture company would be formed. While AMDC would hold 12.5 per cent equity, Birla Corporation would hold the rest. The plant would have one million tonne capacity, which will be set up with a capital expenditure of Rs 600 crore.
