Solvay process - Wikipedia

The principal byproduct of the Solvay process is calcium chloride (CaCl 2) in aqueous solution. The process has other waste and byproducts as well. Not all of the limestone that is calcined is converted to quicklime and carbon dioxide (in reaction II); the residual calcium carbonate and other components of the limestone become wastes.
