The flyash based cement grinding production facility of Gujarat Ambuja Cements Ltd (GACL) at Ropar started operations last week to expand the company’s production by a million tonnes.  The company also announced investment of Rs 2 billion ($US43.3m) at its Ropar facility once the captive power plant becomes operational.  "With the new unit, GACL’s Ropar thermal power plant will utilize 800,000 tonnes of flyash annually and thus become the first of its kind in India to implement 100% utilization of flyash", GACL Chairman Suresh Neotia said.  The Ropar plant will produce 2.5Mt of cement annually.  With this round of capacity expansion aimed at strengthening GACL’s presence in north Indian market, total production capacity now stands at 14.5Mta, Neotia added.
