AHMEDABAD: Gujarat Narmada Valley Fertilizers Company (GNFC) said it has developed a technology, in partnership with the Central Salt and Marine Chemicals Research Institute (CSMCRI), that converts wastes generated at GNFC's Bharuch-based plant to calcium carbonate.
"The technology removes inorganic impurities present in wastes, generated by the fertilizer plant, and converts it to precipitated calcium carbonate," CSMCRI Senior Scientist and Deputy Director R V Jasra said.
The calcium carbonate generated is of high quality and is used as a raw material by industries manufacturing paints, paper, PVC pipes, toothpaste and rubber, Jasra told PTI.
"Traditionally, natural limestone extracted from earth is used to manufacture precipitated calcium carbonate. But through the technology, the same can be manufactured from wastes," he said adding both CSMCRI and GNFC have been jointly awarded a patent for this technology.
GNFC, which had teamed up with CSMCRI in 1998 to device ways to treat 300 tonnes of daily waste generated, is now in the process of commissioning a full-fledged calcium carbonate plant at Bharuch with a daily capacity of 100 tonnes, Jasra said.
