Abstract
Tajmahal (India), one of the Seven Wonders of the World, was built using marble stones. The white shiny marble stones are polished to use as flooring tails, wall tails, to make different statues and decorative items. Millions of tons of solid waste is being generated every year from marble industries. The solid waste from marble industry can be converted into food grade calcium carbonate. The solid waste is made into slurry with 30-40% solids. It is dissolved in dilute hydrochloric acid and precipitated as calcium carbonate using sodium carbonate. The product quality analysis matched with food grade calcium carbonate.
