The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …
