Gujarat is one of the largest producers of portland cement with a number of cement plants spread in and around the state. Most of them use lignite- procured from the Gujarat Mineral Development Corporation Limited’s mines at Panandhro (about 120 Km from Bhuj) as a fuel and limestone (a hard sedimentary rock composed mainly of calcium carbonate, obtained as a surface miner or blasted material) as the major raw material for production of cement. The Bhuj transport division transports limestone to Shree Digvijay Cement Company Limited (www.adityabirla.com/our_companies/indian_companies/shree_digvijay_cement.htm in Sikka, Jamnagar district, Gujarat India) as well as M/ s Gujarat Sidhee Cement Limited (in Morasa, Veraval district, Gujarat, India- www.mehtagroup.com/gs_cement.htm).
