Calculating CO2 emissions from the production of lime
construction, pulp and paper manufacturing, and water purification. Lime is produced in a two or three step process: stone preparation, calcination, and hydration. Calcination is the process by which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO).
