1. A method for producing a clinker from a solid comprising calcium chloride comprising:
(a) combining the solid comprising calcium chloride with a solid comprising silica to produce a solid composition comprising calcium chloride and silica, wherein the molar ratio of Ca: Si in the solid composition comprising calcium chloride and silica is 2.5 to 3.5;
(b) dechlorinating the solid composition comprising calcium chloride and silica to produce a dechlorinated composition comprising Ca and having less than 10% w/w Cl; and
(c) heating the dechlorinated composition in the presence of a flux to produce a clinker.
