In this study carbide lime waste was used as raw material to produce precipitated calcium carbonate (PCC). Carbide lime is an industrial waste from acetylene gas industry which uses limestone in its production. The use of PCC as fillers in paper making can reduce the production cost and improve the paper properties such as opacity and brightness. PCC can be produced from carbide lime waste by ionic sucrose solution method. The sucrose solution of Brix 10° was first prepared by dissolving sugar (sucrose) in water followed by dissolution of carbide lime waste in the sucrose solution.
